Deep long-acting cost-saving fertilization method for kiwi fruits

Abstract

The invention belongs to the technical field of kiwi fruit management, and discloses a kiwi fruit deep long-acting cost-saving fertilization method, which comprises the following steps: determining problems existing in kiwi fruit orchard fertilization; an organic fertilizer with good water absorption and permeability is adopted as a basis and is mixed with NPK macroelement, medium element and microelement chemical fertilizers to form a formula fertilizer; a cylindrical easily-degradable mesh bag is adopted, and formula fertilizer is filled into the mesh bag to prepare a nutrition column which is a fertilizer source for kiwi fruit fertilization; drilling holes in soil layers around the kiwi fruit trees, inserting nutrient columns into soil holes by utilizing high water absorption of organic matters in the nutrient columns and diffusivity of a high-concentration slow-release formula fertilizer, and continuously releasing nutrients and moisture to the periphery by the nutrient columns; the nutrition columns are replaced according to a certain time interval. Loss and waste of the fertilizer are completely eradicated; the application efficiency of the fertilizer is improved, the labor for fertilization is saved, certain anti-waterlogging, drought-resisting and disease-preventing effects are achieved, and the acre yield and the fruit quality of the kiwi fruits can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of kiwifruit management, and in particular relates to a deep and long-term cost-saving fertilization method for kiwifruit. Background technique [0002] The roots of kiwifruit are fleshy roots, with shallow roots, soft wood and weak stretching force, and the roots are basically distributed in the range of 10 to 40 cm deep in the soil layer. The roots are intertwined into a network, and the regeneration is poor. Deep fertilization can easily lead to serious root fractures, affect root growth, and easily induce diseases. The usual furrow application and hole application will cause root damage and fertilizer burning. In recent years, the surface application method of fertilizer has been promoted, which causes the root system to be far away from the fertilizer. It mainly relies on the infiltration of surface water to transport nutrients to the kiwifruit tree, which is slow and time-consuming. Lag, kiwi fruit tr...

AI Technical Summary

Problems solved by technology

[0004] (1) The current furrow application and hole application will cause root injury and fertilizer burning, which will affect the growth of the root system and easily induce diseases

[0005] (2) The current technology of surface spreading causes the root system to be too far away from the fertilizer, and the process of nutrient infiltration to the vicinity of the root system is long and slow, and is restricted by water shortage, which cannot meet the nutrient needs of kiwifruit growth in time

[0006] (3) After fertilization on the surface of the prior art, it is difficult for the organic fertilizer to enter the deep layer of the soil, which has a poor effect on soil improvement

[0007] (4) The terrain of the orchard on the hillside of the prior art is uneven, and the utilization rate of the fertilizer applied on the surface is extremely low

At the same time, after surface fertilization, a large amount of fertilizer will be lost with heavy rainfall, causing environmental pollution and waste of fertilizer

[0008] (5) The number of times of fertilization in the prior art is large, the amount of fertilizer is large, and the amount of labor is large, which increases the production cost

[0009] The difficulty of solving the above problems and defects is: the above technical problems generally exist in the production of kiwifruit in various places. At present, it mainly relies on increasing the amount of fertilizer to make up for the lack of fruit tree absorption, and the production cost is extremely high. At present, there is no effective and low-cost method.
