Embodiment Construction

[0007] A protected farming method in arid areas. After the crops are harvested in the autumn of the current year, combined with deep plowing, fertilize the soil according to the types of crops to be planted in the next year, and then cover the fertilized soil with straw at a rate of 15,000 kilograms per hectare. In the second year Cover the plastic film according to the type of crops to be planted in spring, keep the straw between the two plastic films, and plant according to the conventional method when planting. The ratio of 7,500 kg per hectare is covered with plastic film with straw. In the early spring of the third year, the straw covered in the first year has basically rotted. Cover the row with straw in the second year and plant according to the conventional method when it is to be planted. The operation of deep plowing and fertilization in autumn is the same as that of the first year. In this way, the soil moisture is preserved, the soil is fertilized, and the effect o...

Abstract

The invention relates to a protected land farming method in arid region, falling into the technical field of farmland protection, to solve the problems of spring drought, difficult seedling emergence, lean soil, low crop yield, etc. The protected land farming method comprises the steps of deep plowing after crop harvest in autumn of the current year, applying fertilizer in soil according to type of to-be-planted crops in the next year, covering straw on the fertilized soil at amount of 15,000 Kg / hectare, mulching film according to type of to-be-planted crops in spring of the next year, keeping the straws between two films, and planting according to conventional method. The protected land farming method utilizes waste straw to retain moisture in arid land soil, prevent water evaporation, fertilize soil, and prevent water / soil loss.

Description

technical field [0001] The invention belongs to the technical field of cultivated land protection, and in particular relates to a cultivation method for protected land in arid areas. Background technique [0002] my country's dryland agricultural areas account for 52% of my country's total land area, distributed in 16 provinces in the north, with a total area of ​​about 33 million hectares, accounting for 1 / 3 of the total cultivated land area. Currently, plow-type plows are commonly used in northern arid areas to plow and the surface is exposed for leisure. The upper soil is severely eroded by water and wind, resulting in barren soil, turbid rivers, and rampant sandstorms in the northern region. Valuable arable land resources are constantly being destroyed. Restricts the sustainable development of agriculture. Contents of the invention [0003] The invention mainly aims at the problems of drought in dry land in spring, difficulties in sowing and emergence of seedlings, po...
