Orchard soil aeration and fertilization 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

[0001] (1) Technical field [0002] The invention relates to a method for aeration and fertilization of orchard soil, belonging to the field of orchard soil management and fertilization. [0003] (2) Background technology [0004] The root system is the foundation of the plant, and it is 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, which not only limits root growth, but also It will affect root metabolism and nutrient absorption due to lack of oxygen, and even cause some roots to suffocate and die, eventually leading to weak tree growth and fruit tree yield reduction. Therefore, improving soil permeability is very important for fruit tree growth and fruit production. [0005] Fertilizing can provide n...

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.

[0008] Film-covered hole fertilizer and water storage technology has a good water-saving effect in dry 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. If it exceeds 40cm, the root system cannot be guided to develop deep. In addition, the storage of fertilizer water in plastic film-covered holes mainly considers water saving, and does not consider soil air permeability, nor does it consider the ratio of nitrogen, phosphorus, and potassium nutrients; moreover, the diameter of the fertilization hole is more than 30cm , relying on soft grass for support, it is easy to be trampled

[0009] 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
