Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of furrow mulching cultivation method that improves natural rainfall infiltration, storage and utilization, so as to solve the problem that the partial pressure of carbon dioxide in the soil in the film existing in the existing full-film mulching technology is too high, making it difficult for deep roots and microorganisms to breathe. The problem of low soil nutrient turnover

Embodiment 1

[0016] Embodiment 1-taking corn as example, specifically illustrate the present invention:

[0017] Step 1. After the previous crops are harvested, stubble shall be removed in time, deep plowing shall be carried out, and moisture shall be preserved in time. Before the soil is thawed (one month before sowing), apply enough fertilizer, turn the surface soil by rotating or shallow sowing, and turn the chemical fertilizer into the underground.

[0018] Step two, ridging. In order to prevent the evaporation of water on the ridge, the method of mulching while forming the ridge is adopted. The size of each ridge is equal, the width of the ridge is 35-37cm, and the height is 20-22cm. Sowing is carried out on the ridge with a distance of 20cm. The two ridges connect to form an open ditch and a dark ditch (ditch width 20-22cm) as a rain collection ditch.

[0019] Step three, lamination. Cover with 120cm wide plastic film, and the plastic film boundary is compacted with soil at the s...

Abstract

The invention discloses a furrow covering cultivation method capable of increasing natural rainfall infiltration, storage and utilization and aims to solve the problems that the partial pressure of carbon dioxide of soil in a film in the whole plastic-film mulching technology is excessively high, deep root systems and microorganisms have breathing difficulties, and soil nutrients are low in circulation rate.The method includes: mulching and ridging are performed at the same time, mulching is performed on the ridges, an open ditch and a blind ditch are arranged at the connection of two ridges at interval, the blind ditch is a rain collecting ditch, and the open ditch is covered by crop straw.The method has the advantages that the defect that the whole covering on double ridges and planting in catchment furrows excessively consumes deep moisture and the moisture on the film evaporates easily, and the method is significant to soil moisture recovering and sustainable development of soil water.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a crop cultivation method. Background technique [0002] The natural conditions of dry farming on the Loess Plateau are harsh, with little precipitation, uneven temporal and spatial distribution, water shortages, and nine droughts in ten years. Therefore, dry farming occupies a very special position in the rural economy of this area, and it is particularly important to vigorously promote rainwater-harvesting and water-saving technologies. Although the full-film double-furrow sowing technology has been widely promoted in the past few years, and has greatly promoted the high and stable yield of crops in dryland areas, the high and stable yield brought about by this technology is based on excessive consumption of soil moisture and nutrients. At the same time, it will inevitably lead to the unsustainable development of dryland agriculture. For example, the aerial root activit...
