Camellia growth, development, flowering nutrients needed for the various elements. Camellia enthusiasts but generally only know that irrigate and fertilize, little is known about the emergence of many pathological Camellia is caused by the lack of certain elements. This brief description:
(1) the lack of nitrogen in the growth performance of camellia leaves. Needs adequate nitrogen fertilizer, otherwise the leaves can not flourish if the lack of nitrogen in the growth period of quality fertilizer Wang, performance Camellia old leaves yellow. If too much nitrogen fertilizer quality, the leggy branches and leaves of Camellia performance, resulting in buds infertility and so on. Growing support proper fertilization is so important part of camellia.
(2) the lack of performance of the element phosphorus Phosphorus is the main nutrients camellia flowering and fruiting, if phosphorus fertilizer shortage, resulting in no strong bud, flower shrinking down serious bud, flower. Lack of phosphorus fertilizer, also affected cell formation and proliferation of Camellia. Camellia plant growth led to the slow, old leaves appear dark purple.
(3) the lack of potassium in potassium can promote the performance of Camellia dry robust, enhanced external resistance. Once the lack of these elements in plants, the sick were as follows: tip and leaf margin Kujiao, leaf wrinkling, old leaves turn yellow and so on.
(4) the lack of performance of iron when iron deficiency within the plant Camellia, the sick were as follows: Camellia plants lack vigor, leaf color from green to yellow, then become pale, slow-growing branches.
(5) the lack of sulfur in the performance of camellia plants if the lack of sulfur fertilizer, leaf color changed from dark green, then becomes gray.
(6) the lack of performance of magnesium Magnesium is an important component of chlorophyll composition. If the lack of such elements camellia leaves, leaf chlorosis of the central and edge to white, and white spots appear on the veins.
(7) lack of expression of calcium with calcium to promote the growth of radicle Camellia function. If the soil is low in calcium, Camellia's performance: loss of green leaves, leaf edges curl up, and white stripes appear.
(8) lack of performance Pentu boron boron is missing, lost camellia leaves pale green, the edges curl-shaped leaves, buds atrophy is not long.
(9) lack of performance of zinc in zinc deficiency in camellia leaves, the sick were as follows: camellia leaves turn yellow, sometimes white, branches software, Ye quality thin.
(10) lack the performance of cobalt camellia leaves a lack of cobalt, the sick were as follows: leaf color from green to pale, whole leaf upward bend, but not curly. Camellia
observation that the lack of (1) to (4) some of the elements, it is timely fertilizer complement. If the missing (5) to (10) some of the elements, not simply to make fertilizer, because these trace elements, camellia needs little change as long as the soil can be solved Fanpen, because the new soil has these elements.
one to apply to the soil.
Soil is the basis for the growth of potted camellias, camellia roots because the soil dependent growth, development, life activities Camellia water and nutrients needed for the main draw from the soil. Camellia like acidic, with high humus, loose ventilation of the mountain red (yellow) loam, pH value of 5 to 6.5, can not be used alkaline earth or heavy sticky soil for potted camellia matrix.
Soil preparation: Mountain soil (crops ripening red loam) 50%, 40% wood chips or mushroom residue, cake flour or livestock manure and phosphate powder 10%, three mix, watering amount of equipment bags of aging, aging time: the summer and more than 20 days, more than 30 days in spring and winter, this is not only loose soil aeration, but also water and fertilizer for growth and development of the camellia.
second light to moderate. Camellia requires appropriate light, afraid of hot direct sun.
spring, late autumn will see the light of camellias and more to move to the balcony or on the ground, receiving all-day light, to promote plant growth and development, make it flower bud, bud robust.
into the summer sun is most intense, it is necessary to move the pots to light back positive, well-ventilated environment, conservation, can also be moved to the north or south of the balcony on the balcony below the Growing support, you can also use the 75% shade net, from 9 am to 5 pm the plant cover to avoid direct sun, causing injury or small plants wilted leaves, Camellia conditions will move the safe passing summer sun roof.
three to appropriate temperature. Camellia physiological temperature is an important condition. Camellia likes the warm, optimum growth temperature of 18 ℃ to 25 ℃, relative humidity 60% to 65%.
Camellia growth, mid to late spring shoots sprout normally in 3, April began to bud, 5 months late terminal bud formation, stop growing and gradually differentiated leaf buds or flower buds, flower bud formation from flower to 180 until days to 240 days. Germinating in late summer shoot in July to stop growing in early September. Camellia Although low temperature, but the cold case of invasion, the temperature suddenly dropped below 0 ℃ or Northwest are faced with drying winds, frost damage can cause young shoots, buds are withered by the frost damage, for which it will move back north to the south at the flower pots conservation, to make it safe winter.
Fourth, appropriate humidity. Camellia leaves and more leaf area, transpiration fast. Camellia like high humidity climate, but also hi moist soil. Therefore, make up the moisture to give potted camellias,
watering in spring and 1 day during the growing season, especially in the summer water 1 to 2 times, to maintain a certain air humidity, the growth of plants to flourish. Also, note that for water, and most families are pouring tap water, constant, daily pot of soil is alkaline. To this end, the watering, the monthly supplement poured 0.5 to 1% ferrous sulfate in water, can also be used 5-8% edible vinegar solution were sprayed on the leaves. Camellia like moist soil, but was worried about water flower pots, in the rain if the basin water must be immediately removed to avoid smothering roots immersed in water, rot.
five to moderate nutrients. Hi fat camellia flowers is because of robust growth vigor, leaf more, and longer flowering period, and thus nutrient requirement abound.
in the fertilization process, enough fertilizer, combined with adequate long-term fertilizer Huanpen facilities, according to pot size, pot Shi maturity 3-80 g cake flour, put it under the pelvic floor and the subsoil and mix well. According to plant growth stage, application of organic fertilizer.
addition to the hottest summer and winter when the cold outside, applied 1 month to 2 times decomposition of water, oil cakes.
its application methods: the basin edge about soil clawed through the 2 points, the liquid fertilizer is applied into the trench covered with soil to avoid smell. The maturity of the cake can also be applied in the basin edge and the powder mix basin earth, so that flowers slowly absorbed.
city took on the flower market to buy flowers for the Friends of special fertilizer, hygienic and safe. In order to grow better Camellia, Camellia peanut strong in the period of 1 month to 2 to the outer-root fertilization, to 0.2 to 0.3% potassium dihydrogen phosphate and 1% to 2% of auxin spraying leaves. Fertilization principle: should not re-light, light should not be thick, should be less is not appropriate, we must adhere to the method of thin manure handling facilities, especially not applied raw manure.
six to fit the environment. Camellia like to moderate the growth of air flow in the growth environment, the most favorite breeze blowing, it is the water vapor hi southeast winds, but the fear of northwest wind and wind, leaving the fast evaporation of water, camellia supply and demand out of balance, but also easy to plant and leaf damage, resulting in the phenomenon of plant falling off the bud. Camellia on the sheltered sunny winter to conserve the environment, and a certain temperature and humidity. Spring and autumn, move pots to a balcony, making it air and light, by the wind shaking, so plant growth is not only good, but also conducive to differentiation, growth and development of flower buds, but also to reduce the incidence of pests and diseases. Through years of practice have shown that moderate ventilation, appropriate lighting, can play a role in the prevention of pests and diseases.
site maintenance and management
place: Camellia should be placed in warm and humid, air and light areas. Spring should be light enough, Xia Jiyi attention shade, avoid direct sunlight and 西晒, if placed on the balcony, often accidentally, it was Shaisi. Winter should put more than 3 ℃ room temperature in the room.
watering: Camellia bonsai cultivation of the state to keep the soil moist, but not too wet, to prevent dry when wet. Usually poured in the spring may be appropriate to facilitate the germination Choushao; summer, insisted the morning and evening watering, the best foliar spray of water, the leaves wet,cheap UGG boots, do not use emergency water poured straight, full irrigation, not pouring hot water, to avoid open when the water temperature before and after noon; Fall watering should be moderate; winter watering should be in around noon, you can spray water once every two or three days.
fertilization: hi camellia fertilizer in the basin need to be aware when you put in the basin ground in the basal to the main P and K, applying fertilizers, bone meal, including post-maturity, hair, feathers, Longkang ash, poultry manure and the SSP and other substances. Usually not too much fertilizer, generally 4 to 5 months after flowering 2 to 3 times between the thin applied fertilizer, fall in Nov. fertilizer applied can be a little strong. Fertilizer should be noted that slightly larger proportion of phosphate to promote flower Fan Seyan.
trim: slow the growth of Camellia, not over-pruning, the general will affect the leggy branches and tree pest branches, weak branches can be cut. If too many buds on each branch can be sparse flowers leaving only 1 or 2 and maintain a certain distance, the rest put off early to avoid consumption of nutrients. Also, close in time pluck the flowers wither, but also reduce nutrient consumption in order to facilitate robust plant growth, the formation of new buds.
Fanpen: Camellia bonsai can be 1 to 2 years Fanpen a new basin basin should be larger than the old One, to facilitate the development of root stretch. Fanpen time should be in the spring in April and autumn can be. Removed with the appropriate part of the compacted soil replacement of the old soil and replace loose fertile new soil, and place the basal binding.
pest control: Camellia mainly black mold disease, anthrax, etc., can be sprayed to control Bordeaux 0.5 degrees. There are tea shoot moth pests, pest control methods can be cut off tip, generally carried out in 4 to 6 months is appropriate. 2000 times can be sprayed with pesticides methamidophos control, spraying time, the end of March, early April, when the light is appropriate against overwintering larvae. Spraying must be leaves, wet the young shoots so far. Camellia conservation
quit I quit the bud early July the second ring and leaf fertilizer applied during the three-ring concentrated fertilizer before new leaves in a mature Bordeaux mixture spray of urea or four ring
precepts ground through the summer without watering change position during the spring and summer quit six to seven ring three times spraying foliage fertilizer
Camellia anthracnose disease is one of the common camellia, Camellia leaves major damage, occurs at the tip and leaf margin. Is a fungus disease, infection by the spore camellia caused gill plate. The prevention and cure: 1, timely removal of diseased leaves destroyed. 2, to prevent sunburn, insects and frost damage caused by the wound. 3, reasonable fertilization and watering. 4, to protect the new shoots, the shoots sprout just when spraying 50% ammonium Dyson 1000 times. 5, incubation period,UGG BOOTS, 50% Tuobu Jin sprayed 800 times, 1 spray every 7-10 days,UGG boots, continuous spray 2-3 times before prevention and cure of the disease. (This drug is commercially available)
(3) sporadic not control, contiguous infection when the disease, with 29% lime sulfur from 100 to 200 times and 30% Magnesium sulfate suspension 400 ~ 500 times (before the onset of spraying), 27% copper 500 ~ 800 times high, 4% of agricultural agent against 120 600 800 times, 25% of the Miami West SC 100 ~ 200mg / L concentration of drug liquid, 20% copper thiophene 500 ~ 800 times bacterial spray.
