Fruit tree and fertilizer application

  Fruit tree and fertilizer application play a great role in the growth and yield increase of fruit trees. It is reasonable to use the fertilization fertilizer. Mastering the use of fruit trees and applying fertilizer will greatly improve the efficiency of fertilizer use and have a good effect on fruit trees. The method of using fruit trees for fertilization is introduced as follows:

Instructions:



    Many varieties of fruit trees have different germination, flowering, fruit expansion and maturity stages, but the root growth law is roughly the same as the fertilizer requirement in each period.



    1. Beginning in March every year, when the ground temperature exceeds 5 degrees, the sap begins to flow, and the roots of the fruit trees slowly start to move. As the ground temperature gradually increases, the growth of the roots increases, and the fruit trees begin to germinate, flower and store nutrients. It marks the arrival of the first large amount of fertilizer. The root activity period is about 30 days, nitrogen can promote the growth of branches and leaves, so the topdressing should be based on nitrogen fertilizer.



    In the arid areas, the fruit trees need a lot of watering during the germination period, and can be combined with watering for 8 kg of fruit trees per acre. Flowering consumes a lot of nutrients, and after the flower grows, the leaves begin to grow, and the fruit begins to expand for the first time. These require a large amount of nutrient supply. Therefore, the fruit should be topdressed after the fruit tree falls. At this time, the water can be used to combine the water and the roots. Stars, trees are about 8 kilograms per mu, and the tree is weak and the amount of flowering is about 12 kilograms per mu.



    2, June fruit tree into the flower bud differentiation period, the root system also began to enter the second growth peak. Phosphate fertilizer can increase sugar and acid, promote flower bud differentiation, and has the name of “flower fertilizer”. Combined with watering, it can be applied to 8-12 kilograms of Wei Nong Le Genxing, or 6-9 kilograms of Wei Nong Le Gao Potassium, and supplemented with trees. Body nutrition, restore the tree.



    3, 7-9 months, the roots of the fruit trees enter the third growth peak, and the fruit also enters the second and third expansion periods. It is also the flower bud formation period and the fruit coloring period. Potassium fertilizer can significantly improve the fruit quality and promote the fruit. In this period of expansion, potassium fertilizer should be the main factor. Summer is the rainy season. These two top dressings should look at the topdressing fertilizer, and the fertilization should be used well. It has a great effect on fruit coloring, fruit, and sugar.
