Winter fertilization technology of Camellia?

　　 According to the different requirements of the growth and flowering of Camellia, the following fertilization periods should be mastered: the first fertilization should be carried out from February to March. At this time, most Camellia flowers begin to germinate and should be fertilized with nitrogen fertilizer. Promote the sprouting of sprouts. The second fertilization should be carried out from April to May. In April, nitrogen fertilizer and potassium dihydrogen phosphate can be applied alternately to promote the strong growth of new shoots and provide necessary nutrients for the differentiation of flower buds. In May, the new shoots have all been lignified, and the flower buds have been Beginning to differentiate into flower buds, at this time, phosphate fertilizer-based fertilizer should be applied to increase the nutrients needed for flower bud formation.

　　  The third fertilization should be carried out from late June to mid-July. At this time, the temperature gradually rises, the plant grows slowly, and the nutrient is absorbed less. The thin fertilizer solution mainly based on nitrogen fertilizer should be applied. If the concentration is too high, it is easy to burn the roots. From late July to August is the high temperature dormancy period of camellia, so no fertilizer can be used. The fourth fertilization should be carried out from mid-November to mid-October. At this time, the Camellia plant enters the second growth period, the sap activity is strong, the roots continuously absorb water and nutrients, and the auxin is formed by photosynthesis, so it is necessary to timely fertilize the soil. It can be applied with nitrogen fertilizer, phosphate fertilizer and about one percent of superphosphate to form a mixed fertilizer solution to meet the nutrients needed for autumn growth and enhance the cold resistance of the plants in winter, laying a good foundation for the full bloom of the spring flowers. .
