The requirements are complete(plastic nursery pots wholesale), the proportion is coordinated, the fertilizer is large, the concentration is high, and the application is timely. According to the principle of “diligence and application, less and less, less first, then less, first and then thicker”, the time of fertilization should be short, the concentration should be light, the number of times should be more(12cm plastic grow pots), the amount of fertilizer should be less, and the age of the tree increases.(greenhouse 7 inch plastic terracotta plant pots)
4 to 7 years old trees, every two months in February and August, topdressing once(black plastic nursery pots), still in the early stage of nitrogen, potassium as the second, phosphorus again, the middle and late application of nitrogen, phosphorus and potassium ternary compound fertilizer, but the amount of fertilizer should be with the age of the tree Increasing year by year and increasing in synchronization(plastic terracotta pots wholesale). The ratio of application of NPK for the whole year is preferably 1:0.7:0.8.
Spray 300-350 times of borax water in April and June each year to promote early production. As a result, the tree should be fertilized three times a year, and the ratio of nitrogen, phosphorus and potassium required for the whole year is about 1:0.85:0.9. In March of the flowering period after germination, each plant was sterilized with 100-120 kg of human waste(16cm plastic grow pots), or 350-400 g of urea, to promote hair shoots and flowering results, and to improve fruit set rate and yield.
(greenhouse 7 inch plastic terracotta plant pots)Each plant can apply 400 kg per mu after transplanting(plastic nursery pots). Apply NPK fertilizer every 40 to 45 days, and apply 30-40 grams of compound fertilizer per plant per plant to promote the development of shoots. It contains red soil or yellow soil with low effective phosphorus and less boron, and applies appropriate amount of chemical phosphate fertilizer and boron sand(15cm plastic grow pots). The concentration is 3500 times of manganese sulfate and 2500 mg of magnesium sulfate~3000 times.
The borax is sprayed at the flowering stage, preferably 300 to 350 times(plastic nursery pots manufacturers). And the decrease is increased and the concentration is increased. 1 to 3 years old tree, from the beginning of February to the end of May, every 40 to 45 days to apply a quick-acting nitrogen fertilizer(120mm plastic grow pots), each time each plant is sautéed with 15-20 kg of human waste and 20-30 g of urea to promote the germination and growth of the branches and leaves.
Generally, the roots are covered with trees in the whole garden, and are dug with rows or buried in the whole garden(cell trays). According to the measurement, during the rapid expansion of the fruit, each plant applied 800-1000 grams of NPK compound fertilizer to promote fruit development and improve quality. Fertilizer can be used for manure, compost, soil and fertilizer(14cm plastic grow pots), waste fertilizer processed by tanning, sugar mud, green manure and cake fertilizer.(greenhouse 7 inch plastic terracotta plant pots)
Generally, it is best to apply it from September to October after fruit picking(wholesale nursery pots). When the branching buds start to branch, 1000 kg of decomposed manure is mixed with 25 kg of superphosphate and combined with the soil. In addition, regardless of small trees and large trees, in the growing season from May to July, pesticides should be sprayed in combination with pest control(13cm plastic grow pots), and manganese and magnesium elements should be added to supplement the micro-fertilizer.
(greenhouse 7 inch plastic terracotta plant pots)The method uses a semi-circular ditch, a radiant ditch, a fan-shaped pit and a strip-shaped ditch(16.5cm plastic grow pots). If there is a lack or deficiency, when the bud is bud, the topdressing fertilizer will be used in the case of insufficient fertilizer. When transplanting the chrysanthemum seedlings, use 5 kg of urea and 10 kg of superphosphate mixed with each other(12.5cm plastic grow pots), and spray 3 times with 0.5%-1% potassium dihydrogen phosphate, once every 7-10 days.
