Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with embodiment. It should be pointed out that those skilled in the art can make some improvements without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.

[0016] Implementation location: Lishu Garden, Zhenjiang Academy of Agricultural Sciences Park, Huayang Town, Jurong City

[0017] Specific implementation: a soil improvement method for reducing soil bulk density. The method is to evenly cover the orchard soil with naturally air-dried rice straw in December, and implement the whole orchard coverage and compaction slightly. And compared different coverage amounts, the comparison results are shown in Table 1.

Abstract

The invention discloses a soil improvement method for reducing the volume weight of soil. Straws are used for covering the soil; and the straws are rotted under a natural environment state and then are returned back to the soil or the straws are rotted under the action of native bacteria and then are returned back to the soil, wherein the use amount of the straws is 6.25kg / m<2>-12.5kg / m<2>. Compared with a method for reducing the volume weight of the soil by covering the straws on an orchard and other methods, the aim of reducing the volume weight of the soil can be achieved without the need of damaging a physical structure of the soil, and the covering of the straws can be carried out all the year round; and the straws are brought into the orchard and wastes are changed into valuable things, so that agricultural wastes are treated, the soil is improved and the ecological environment is protected.

Description

technical field [0001] The invention relates to a soil improvement method for reducing soil bulk density, in particular to a soil improvement method for reducing soil bulk density by covering orchards with rice straw. Background technique [0002] With the improvement of people's living standards, the demand for fruit is increasing, so the size of orchards is increasing. The basis for determining the fruit yield and fruit quality of an orchard is the soil quality. The level of soil bulk density directly affects the extension of fruit tree roots and the absorption of soil nutrients by fruit tree roots, which also affects the yield of fruit trees and fruit products. the quality of. Rice and other crop stalks can be seen everywhere in the countryside. They have become wastes with large output but little use in rural areas, and are not easy to handle. Most of them are disposed of by incineration, which seriously pollutes the environment. Straws are introduced into the dry land ...
