How to apply the base fertilizer in the autumn of the orchard:
In the autumn, the orchard should be applied to the base fertilizer, which is conducive to storing nutrients and promoting growth and development. For the management of orchard, many fruit farmers attach importance to tree management and despise underground management; it is not right to pay attention to the management of fruiting period and to despise management after fruit harvesting. Underground management and post-harvest management are as important as growing season management, especially in the fall season. Because the fruit trees consume a lot of nutrients through the fruit of a growing season, the autumn base fertilizer can make the tree nutrients be replenished in time, which can make the flower buds more substantial, which is conducive to flowering and fruiting in the coming year. Not only that, the autumn application of base fertilizer is conducive to the maturity of organic fertilizer, so that the fruit trees store nutrients during the growth period before the leaves, which is conducive to the growth and development of the fruit trees in the coming year, and the roots that are excavated during fertilization can be repaired in time.

The autumn base fertilizer should be carried out after fruit picking and when the autumn shoot stops growing. Generally, in September and mid-September, late-maturing and late-maturing tree species can be carried out before fruit picking. Linyi Fertilizer Network Copyright
The type of autumn-based base fertilizer should be mainly based on decomposed farmyard manure containing more organic matter, such as compost, circle fertilizer, straw fertilizer, pig and sheep chicken manure, human excrement and so on. The organic fertilizer is slowly decomposed and has a long fertilizer effect. When applying the basic fertilizer in autumn, it can be combined with the application of NPK fertilizer to apply NPK compound fertilizer, and apply multi-element micro-fertilizer to achieve balanced fertilization. The amount of fertilizer applied in autumn can account for 60%-70% of the annual fertilization amount. In addition, the amount of fertilizer to be applied depends on the variety, age, and tree potential. Large trees, weak trees, and young trees and saplings. The result tree requires that the total amount of organic fertilizer and inorganic fertilizer should reach “jinjinjinfeiâ€, and the high-yield orchard with a yield of more than 2,500 kg per mu should also increase the amount of fertilizer.

The method of fertilization should be suitable for trees. The distribution of sapling roots is small, and can be applied by circular groove; mature trees can be used to dig trenches; roots can be covered with orchards and then deep-turned; In densely planted orchards, it is possible to use ditching between rows; for orchards with crops under the trees, caves can be applied.

The depth of fertilization should be different depending on the tree species. Deep root trees such as apples, pears, and walnuts should be applied deeper, generally 30-40 cm in depth; shallow root trees such as peach, apricot, and plum can be applied shallower, generally deep. At 15-30 cm. The orchard with irrigation conditions should be irrigated once after fertilization to facilitate soil sedimentation and fertilizer decomposition, which is convenient for root absorption. In addition, we must pay attention to timely planning to make up for cracks to facilitate drought and cold resistance. Linyi Fertilizer Network Copyright
