Ridge film-mulching soil moisture preservation and rainwater collection ditch water collection method based on dry land fruit tree root system soil hydrothermal environment

Abstract

The invention discloses a ridge film-mulching soil moisture preservation and rainwater collection ditch water collection method based on a dry land fruit tree root system soil hydrothermal environment. Ridges are inwardly made in the vertical projections of crowns, rainwater collection ditches are outwardly dug in the vertical projections of the crowns, fertilization ditches are inwardly dug close to the rainwater collection ditches, black mulching films are spread at the beginning of thawing, and roots are exposed within a range between 3cm and 5cm around the roots of tree bodies; mulching films are spread on the sloped ridge surfaces, and are fixed by longitudinal batten-shaped earth; the films are removed in time in the rainy season in order to keep a good soil environment. The method is based on the rainfall characteristics of local regions, a fruit tree moisture utilization principle and the keeping of a good root zone environment. The technique is easy to operate, the cost is low, and the method has the technical effects of water preservation, water storage, evaporation resistance, centralized moisture utilization, water-promoted fertilization and keeping of the good root zone environment. The method is suitable for apple trees, peach trees, pear trees, grapevines and other fruit trees of different ages in arid regions, and can promote the activity of the root systems of fruit trees and accelerate the growth of saplings and the formation of tree shapes, ensure the stable and increased yield of grown fruit trees and increase the quality of fruits.

Description

technical field [0001] The invention relates to an orchard ridge film moisture conservation and rain collection technology, in particular to a method for dryland orchard inter-row ridge film mulching, moisture conservation, small ditch rain collection, and efficient use of water and fertilizer. Background technique [0002] The Ministry of Agriculture announced the "Regional Layout Plan for Superior Agricultural Products" (hereinafter referred to as "Zone") in 2003. In the "Zone", 12 types of northern deciduous fruit trees, including apples, peaches, pears, grapes, apricots, walnuts, dates, plums, cherries, and persimmons, are specialty fruit. [0003] The total rainfall in fruit tree producing areas on the Loess Plateau in Northwest China is generally around 400mm. More than 80% of the orchards in this area rely on natural precipitation, and the total rainfall basically meets the growth needs of fruit trees. However, the annual and seasonal variability of precipitation in ...

AI Technical Summary

Problems solved by technology

However, the annual and seasonal variability of precipitation in the territory is relatively large, coupled with high-intensity ground evaporation, resulting in frequent regional and seasonal droughts, which seriously affect the growth of fruit trees and the sustainable and stable production of fruit
