Regarding orchard management, many fruit growers attach importance to management on the trees and despise underground management; they attach importance to management during fruiting period and despise management after fruit harvesting. This is not correct. Underground management and post-harvest management are as important as the management of the growing season, and in particular, the use of base fertilizers in the fall cannot be underestimated. Because fruit trees consume a lot of nutrients after a growing season, autumn basal fertilizer can make tree nutrients be replenished promptly, and flower buds can be more substantial, which is beneficial to flowering and results in the coming year. Not only that, autumn basal fertilizer is conducive to the decomposing of organic fertilizers, so that the fruit trees store nutrients before the deciduous growth period, which is beneficial to the growth and development of fruit trees in the coming year. The tree roots excavated during fertilization can be repaired in time.
Autumn basal fertilization should be carried out after the fruit is picked and when the autumn shoots stop growing. Usually in the middle or early September, late-maturing cultivars and late-maturing cultivars can be carried out before harvesting fruits.
The types of autumn basal fertilization should be based on rotten farmyard fertilizers containing more organic matter, such as compost, circulatory fertilizer, straw fertilizer, pig feces and chicken manure, and human fecal urine. Slow decomposition of organic fertilizer, long-term fertilizer. When autumn basal fertilization can be combined with the application of rotten manure fertilizer applied NPK complex compound fertilizer, combined with the application of multi-element fertilizer, to achieve balanced fertilization. The amount of basal fertilizer in autumn can account for 60%-70% of the annual fertilization amount. In addition, the amount of fertilization depends on the species, age, and tree vigor. Big trees, weak trees and more facilities, saplings, Wang trees less. The result tree requires that the total amount of organic fertilizers and inorganic fertilizers be used to reach “high-yield fruitâ€, and high-yield orchards with a yield of over 2500 kg per mu should also be appropriately increased.
The fertilization method should be based on trees and suitable. The young tree roots have a smaller distribution range and can be applied with ring-shaped furrows. The mature trees can be digged with radial grooves. The roots covered with orchards can be applied in the whole garden and then deep-turned. In densely planted orchards, inter-row ditching can be used to apply the method; an orchard with inter-tree crops under the tree can be used.
The depth of fertilization is different depending on the species. Deep-rooted trees such as apples, pears, and walnuts must be applied deeper. Generally, the depth is 30-40 cm. Shallow-rooted trees such as peaches, apricots, and plums can be applied shallowly. At 15-30 cm. The orchard with irrigation conditions should be poured with water once fertilization in order to facilitate the settlement of the soil and the decomposition of fertilizers, so as to facilitate root absorption. In addition, we must pay attention to timely planning, make up for cracks, in order to facilitate drought and cold.
