Rainwater collecting and soil moisture preservation method for dry land apple trees

Abstract

The invention discloses a rainwater collecting and soil moisture preservation method for dry land apple trees. The rainwater collecting and soil moisture preservation method for dry land apple trees comprises the steps of fertilizer application and soil preparation, ridging and film mulching or whole orchard film mulching, digging of rainwater collecting gutters, and straw covering in the rainwater collecting gutters and space between lines. The rainwater collecting and soil moisture preservation method for dry land apple trees is characterized in that soil processing is carried out before fertilizer application and soil preparation, 0.5 kilo of 40% of phoxim emulsifiable concentrate and 30 kilos of compound fine sand soil are mixed into compound poisonous soil to be applied per mu, and the compound fine sand soil is formed by mixing fine sand, horse dung, vermiculite and field soil according to the proportion of 2:2:1:3. The horse dung is dry horse dung with the water container not more than 5 percent and is crushed into particles with the particle diameter of 0.3-0.5 mm. Through soil processing, pests overwintering in the field such as buscks, scarabs and sympiezomias velatus chevrolats can be killed, pest eggs parasitizing the soil can be prevented from growing, and underground pests are effectively controlled. Meanwhile, the compound fine sand soil serves as a pesticide carrier and soil moisture preservation materials, the use amount of the fine sand is reduced, the soil fertility and soil quality of the orchard are kept, and good social benefits can be achieved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for collecting rain and preserving moisture of apple trees in dry land. Background technique [0002] In recent years, my country's apple cultivation has gradually shifted to the loess plateau apple eugenic area, with the west and north as the main cultivation areas. For apple production, these areas have a good ecological environment, light and heat resources, and sufficient land and labor. However, the relatively low precipitation has become a limiting factor for the development of apples in these areas, especially the uneven annual distribution of precipitation. The large amount of water seriously affects the development of the industry. Therefore, the development of water-saving and water-saving measures in dryland orchards has become the focus of attention of fruit farmers. In order to effectively solve the problems of drought and lack of...

Problems solved by technology

[0004] The purpose of the present invention is to: provide a method for collecting rainwater and preserving moisture of apple trees in dry land. Before soil preparation and ridging, the soil is treated with compound poisonous sand to effectively prevent and control the occurrence of underground pests. The method of raising high ridges to cover black film rainwater collection ditch is improved, aiming to solve the problems existing in the actual operation of the existing method
