Problems solved by technology

However, due to the drought and lack of rain in winter and spring, the groundwater source is insufficient, resulting in serious water shortage in the field soil, but it has caused great losses to agricultural production.
Especially in northern China, spring sowing crops cannot be sown on time due to drought, lack of rain or lack of soil moisture, which will bring poor harvests to agricultural production.
Especially for corn and cotton crops, due to lack of rain, they cannot be sown in time or lack of moisture after sowing, resulting in serious lack of seedlings and ridges. They have to wait for the rain to sow and delay the sowing period, resulting in waste of natural resources such as land and light and heat.
In order to alleviate this problem and ensure spring sowing, farmers have adopted many measures, such as: digging wells, constructing farmland water conservancy, and even picking water for planting. Drought resistance before spring planting is a major problem for farmers

Embodiment Construction

[0009] Below in conjunction with specific embodiment, the method for preserving moisture in the spring sowing period of the present invention is described in further detail.

[0010] The method for preserving moisture in the spring sowing period of the present invention mainly includes seven steps of leveling the land, covering with film, pressing soil on the film, opening holes, applying water, sowing, and covering with soil. That is, after the autumn harvest of the previous year, it should be combined with fertilization, and the land should be rotated to level the surface. Before the soil thaws in the early spring from the end of February to the beginning of March next year, use the freeze-thaw layer formed on the surface in winter to cover the soil surface with a 0.008 mm thick degradable agricultural mulch film, and ditch the land around the mulch film to compact the mulch film. The film rate should account for 70% of the land. Press the soil on the mulch to prevent the f...

Abstract

A method for preserving soil moisture in spring sowing season includes such steps as levelling the ground, covering plastic film on the soil, covering some holding-down soil on the film, making caves, irrigating to the caves, sowing in the caves and covering soil and seeds. Its advantage is high effect.

Description

technical field [0001] The invention relates to a method for preserving moisture in arable land, in particular to a method for preserving moisture in arable land with plastic film during the spring sowing period. Background technique [0002] In agricultural production, spring planting is a particularly critical sowing period in a year. Farmers compare the rain when spring comes to "spring rain is as expensive as oil", which reflects farmers' expectation for spring rain. However, due to the drought and lack of rain in winter and spring, the groundwater source is insufficient, resulting in serious water shortage in the field soil, but it has caused great losses to agricultural production. Especially in northern China, spring sown crops cannot be sown on time due to drought, lack of rain or lack of soil moisture, which will bring poor harvests to agricultural production. Especially for corn and cotton crops, due to lack of rain, they cannot be sown in time, or due to lack of ...
