In September, the fruit trees gradually entered the picking period, and the fruit tree autumn fertilizer was the most important and most important fertilization. Don't be careless and careless. First of all, the nutrients consumed by the fruit trees from the early spring germination to the flowering and fruit setting are mainly the nutrients stored in the tree in the previous year. The period from the harvest of the fruit to the time before the defoliation is the best time to accumulate nutrients. The autumn base fertilizer can increase the nutrient reserve of the tree. Secondly, autumn is the last growth peak of the root system in one year. Its life activity is strong, its ability to absorb nutrients is strong, and it is beneficial to delay leaf senescence, enhance the photosynthesis ability of autumn leaves, and increase the nutrient storage of trees. Thirdly, the soil temperature in autumn is higher, and the sensation is better, which is beneficial to soil microbial activities. The organic fertilizer applied is fast and easy to be absorbed and utilized by roots. Studies have shown that fertilization in autumn can increase the effects of nitrogen, phosphorus, potassium, calcium and magnesium by 1, 5, 3, 2 and 2 times, respectively. It is worth noting that the fertilization time is generally from September to October. The demand for nitrogen, phosphorus and potassium nutrients in fruit trees is proportional. At the same time, organic fertilizer should be added to supplement the appropriate medium and trace elements. The fertilization method is ditch. Or acupoint application; fertilization site, inside the outer edge of the crown; fertilization depth, generally distributed in the roots of 20 ~ 40 cm. Therefore, many experts and professors have called for: fruit trees, autumn application base fertilizer is "gold", winter application base fertilizer is "silver", spring application base fertilizer is "breaking copper and iron", and the majority of fruit farmers should fully understand the important meaning.

Finally, fertilization in autumn can improve the root growth environment and improve the tree's resistance to stress. Combined with autumn fertilization and deep soil turning, it can optimize soil structure, improve soil permeability, facilitate root respiration, and improve soil water storage and fertilizer retention.
