High-quality pollution-free apple fertilization technology
Second, top-dressing topdressing should be quick-acting fertilizer-based, according to the strength of the tree, the yield level and whether the lack of trace elements, etc., to determine the type, quantity and frequency of fertilization.
1. The top-dressing time is growing. The tree top-dressing period is carried out for a long time in the spring shoots and autumn shoots of fruit trees. The main use of phosphorus and potassium fertilizers is supplemented with a small amount of nitrogenous fertilizers, and irrigation is controlled; the weak trees are topdressed before early spring germination and before the spring shoots are stopped. The golden mean tree is applied before flowering and before it stops in the autumn. It is carried out 2 or 3 times a year. The first topdressing is carried out before sprouting in early spring. Fertilizer is mainly applied with nitrogen fertilizer to meet the nutrients required during flowering, increase the fruit setting rate, and promote the growth of new shoots; the second top dressing should be better after flowering. Nitrogen fertilizers and fertilizers are mainly N, P and K fertilizers to reduce physiological fruit drop, promote the growth of branches and leaves and flower bud differentiation; the third time should be top-dressing during fruit enlargement, and mainly apply K fertilizer or compound fertilizer to increase the accumulation of tree nutrients and promote fruit production. Expanding to ensure coloring and maturation, improve fruit yield and quality, and enhance wintering and cold resistance of fruit trees.
2. Fertilizer type and amount of nitrogen fertilizer to the main application of urea, with 15 kg per acre; phosphate fertilizer is suitable for diammonium phosphate, with 20 to 25 kg per acre, potassium fertilizer application of potassium sulfate, 35 to 40 kg per acre.
3. Top-dressing methods generally use radial furrow fertilization and annular furrow fertilization. The depth of the fertilization ditch is generally 15 to 20 cm. After the fertilizer is applied, the soil is tightly sealed. If the soil moisture is poor, the top dressing should be combined with watering to achieve better results.
Third, outside the top dressing In order to quickly supplement the nutrients of fruit trees, promote apples to increase, protect the leaves, you can take the method of dressing fertilizer. Specifically, the fertilizer solution is sprayed on the leaves of apple trees and absorbed and utilized by apple leaves to ensure the normal growth of apples and the prevention of deficiency diseases. The topdressing time should generally be performed at 9 to 11 o'clock in the morning or at 2 to 4 o'clock in the afternoon, avoiding the high temperature stage at noon. The site of spraying should be mainly leaves and leaves, and the interval time is 10-15 days. Commonly used fertilizer types and concentrations: 1 Urea can be sprayed after germination, leaf development, flowering, fruit enlargement, and fruit picking. The application concentration is 0.2% to 0.3% in the early stage and 0.3% to 0.5% in the middle and late stages. Potassium dihydrogen phosphate, 0.2% for early use and 0.3% to 0.4% for mid- and late-stage use. 3 Before and after the borax germination with 1%, full bloom with 0.3% to 0.5%. 4 Ferrous sulfate 0.1% to 0.4%.
