Grass growing covering method without deep plowing for kiwifruit orchards

Abstract

The invention provides a grass growing covering method without deep plowing for kiwifruit orchards. The grass growing covering method has the advantages that full-year grass growing and ground covering grass growing virtuous ecological cycle modes are energetically popularized in the orchards, granular structures of soil can be continuously improved, the porosity of the soil can be increased, structural shapes of the soil can be improved, the fertility of the soil can be enhanced, good soil moisture conservation effects can be realized, the utilization rate of moisture in the soil can be increased, the earth surface temperatures of the orchards can be lowered, the potential of hydrogen of the soil can be improved, the stress resistance of fruit trees can be continuously enhanced, diseases can be relieved, accordingly, fleshy roots of kiwifruits can healthfully extend and grow in fertile, loose and air-permeable soil environments, the yield of kiwifruit fruits can be increased, and the quality of the kiwifruit fruits can be improved.

Description

technical field [0001] The invention belongs to the technical field of orchard soil management, and in particular relates to a no-deep plowing grass covering technology for kiwi fruit orchards. Background technique [0002] The soil is the carrier of the orchard, and the quality of the soil determines the production quality, plant life, fruit yield and quality of the orchard to a large extent. As the temperature rises in summer, it has become normal in the north to maintain a temperature of around 40°C. Under the continuous high temperature, the leaves and fruits of kiwifruit trees are severely sunburned. When the soil surface temperature exceeds 30°C and the soil moisture content is lower than 60% of the field water holding capacity, there will be insufficient moisture, and it will be difficult for the roots of the fruit trees to absorb water. The shoots, leaves, and fruits stop growing, and the leaves and fruits begin to compete with each other for nutrients. The division ...

Problems solved by technology

[0002] The soil is the carrier of the orchard, and the quality of the soil determines the production quality, plant life, fruit yield and quality of the orchard to a large extent. As the temperature rises in summer, it has become normal in the north to maintain a temperature of around 40°C. Under the continuous high temperature, the leaves and fruits of kiwifruit trees are severely sunburned. When the soil surface temperature exceeds 30°C and the soil moisture content is lower than 60% of the field water holding capacity, there will be insufficient moisture, and it will be difficult for the roots of the fruit trees to absorb water. The shoots, leaves, and fruits stop growing, and the leaves and fruits begin to compete with each other for nutrients. The division and expansion of young fruit cells are hindered, and even dead shoots, leaves wilt, and brown spots or wither appear on the leaf edges. Extensive scald-like necrosis, severe leaf fall in the orchard, and sunburn and shrinkage of some fruits; the high temperature season in summer is a critical period for kiwi fruit trees to need water. In the orchard, the phenomenon of soil drought and water shortage often occurs due to the continuous rise of surface temperature, and the phenomenon of frequent occurrence The hot phenomenon leads to the evaporation of soil water on the surface of the orchard and the increasing transpiration of the fruit trees, which intensifies the consumption of water and organic nutrients in the fruit trees, seriously affecting the life activities of the kiwi fruit trees; The continuous use of a large number of fertilizers has caused serious compaction of the orchard soil, acid-base imbalance, and serious secondary salinization of the soil, resulting in a continuous decline in soil fertility. The main reason for the proliferation of diseases such as chemical disease, bacterial canker, and brown spot. It is necessary to improve the above-mentioned problems in the soil and fruit trees.
