Orchard soil ventilating and fertilizing method

Abstract

The invention discloses an orchard soil ventilating and fertilizing method. The orchard soil ventilating and fertilizing method comprises the following steps: drilling fertilizing holes at certain intervals by a soil punching machine along the inner edges of tree disks of fruit trees, packing thick organic materials in the bottoms of the holes, inserting bundled corn straw or branches into the bottoms of the fertilizing holes, then filling with organic fertilizer, spraying chemical fertilizer in ratio when the added organic fertilizer reaches a certain height, further adding the organic fertilizer, irrigating after the fertilizing holes are full filled with the organic fertilizer, slightly shaking the corn straws or the branches which are inserted into the holes, and finally covering the fertilizing holes and the tree disks with straw carpets; removing the straw carpets during topdressing in summer, applying the chemical fertilizer in ratio and covering with the straw carpets again. According to the orchard soil ventilating and fertilizing method, the corn straws or the branches are inserted into the fertilizing holes; the air permeability is improved; with the combination of the straw carpets with few same plant diseases and insect pests as the xerophilous plants, the water, fertilizer, air and heat are obviously improved; the temperature and the humidity of the soil are stabilized; the plant diseases and insect pests are reduced; the root development and the nutrient absorption are promoted; the consumption of the chemical fertilizer is reduced; the labor efficiency is improved; the labor intensity is alleviated.

Description

(1) Technical field [0001] The invention relates to an orchard soil aeration and fertilization method, which belongs to the field of orchard soil management and fertilization. (2) Background technology [0002] The root system is the foundation of the plant and the organ through which the fruit tree absorbs nutrients and water from the soil. Metabolic activities such as root growth and respiration require oxygen, and soil oxygen content depends on good soil aeration, but poor soil aeration in the root zone of fruit trees due to trampling, mechanical compaction, and the soil itself not only limits root growth, but also Oxygen deficiency will affect root metabolism and nutrient absorption, and even cause some roots to suffocate and die, eventually leading to weakened tree growth and reduced fruit production. Therefore, improving soil air permeability is very important for fruit tree growth and fruit production. [0003] Fertilization can provide nutrients to fruit trees. At ...

Problems solved by technology

According to the materials used, orchard ground covering can be divided into covering plastic film and grass covering, etc. Among them, covering plastic film is widely used because of its low cost and simple operation, but plastic film brings environmental pollution to the orchard because it is difficult to degrade naturally. At the same time, the air permeability of the plastic film is poor, and covering the ground will reduce the air permeability of the soil, and covering the plastic film will make the soil heat up too high in summer, which is not good for the roots distributed in the upper layer of the soil.

[0006] Film-covered hole fertilizer and water storage technology has a good water-saving effect in dryland orchards, but it is still covered with plastic film, which also has problems such as plastic pollution, reduced soil aeration, and high ground temperature in summer. More than 40cm, the root system cannot be guided to develop to the depth; in addition, the fertilizer water storage in the film-covered hole mainly considers water saving, does not consider the soil air permeability, and does not consider the ratio of nitrogen, phosphorus and potassium nutrients; moreover, the diameter of the fertilization hole is more than 30cm , relying on soft grass to support, it is easy to be trampled

[0007] Orchard ground mulching mainly refers to covering various scattered plant materials such as straws and weeds. Although the overall effect is better, these plant materials are messy and complicated to operate; local straws, weeds, etc. are xerophytes like fruit trees , often carry or breed pathogenic bacteria, pests or weed seeds that attack fruit trees; and the resources such as straw and weeds in the main fruit tree production areas are very limited. New methods of ground mulching need to be developed
