In the spring, many fruit farmers are used to applying base fertilizer in spring, but there is no good autumn. In the spring, the temperature is high, the soil is not good, and the base fertilizer is not fermented for a long time. The tree is difficult to absorb, which causes waste to a certain extent. Applying base fertilizer in autumn, the temperature is suitable, the soil moisture is good, it is beneficial to the decomposition of fertilizer and root absorption, and can timely supplement the tree nutrients, which is conducive to flowering and fruit setting in the coming year. Premature topdressing and topdressing should be applied during the fruit expansion period, and premature nutrition is easily lost. Potassium fertilizer is applied during the fruit expansion period, the fruit surface is bright, the color is bright, and the meat is crispy. If the effect is applied during the flowering period, it is not obvious. Over-reliance on foliar fertilizers Because most of the foliar fertilizers on the market are plant conditioners, the effects after spraying are immediate. Therefore, some fruit farmers applied base fertilizer without topdressing, and individual fruit farmers did not apply fertilizer and topdressing. They relied too much on foliar fertilizer. In fact, more than 95% of the nutrients in plants came from the soil, and the leaf surface absorption rate was very low. The unfertilized manure into the orchard is not directly decomposed into the orchard, which not only does not have the expected fertilization effect, but also pollutes the environment, and is also susceptible to fruit trees and insects.

Partial application of chemical fertilizers Many fruit farmers apply a large amount of chemical fertilizers, neglecting the medium and trace element fertilizers and organic fertilizers, causing excessive waste of nitrogen and a large amount of phosphorus deposition. The direct performance is that the orchard soil is severely squashed, the growth and development of fruit trees are out of balance, the pest control is out of control, and the apple yield is not High, quality is degraded, and the taste is not good.
