Problems solved by technology

The main reasons are: the traditional mulching method of mulching film only partially covers the ground, and 1/3 to 1/2 of the ground in the field is still bare, the effect of warming is limited, and some crops are difficult to mature normally; in addition, the traditional mulching method is to Crops are planted on ridges, which can prevent long-term water accumulation in crop roots in areas with irrigation conditions and re...

Embodiment Construction

[0014] In the present invention, the land is first leveled, and at the same time, enough base fertilizer is applied in the field. Get width 120cm then, ditch respectively along 40cm, 80cm place, form 40cm and 80cm two different wide and narrow ridge surfaces, its ridge height is greater than 5 centimetres. Make each ridge level off through trimming, form the situation as shown in accompanying drawing 1. Then cover the ridges and furrows with mulch. Proceed with sowing.

[0015] A specific embodiment of the present invention is: first row with a row marker with a tooth pitch of 40 cm in the small row and 80 cm in the large row, and then use a step plow to plow the small bow-shaped ridge along the small row to the middle, and the ridge height is 10 cm. ~15cm, between two small arcuate ridges is a large ridge of 80 cm, scrape the furrow formed when the ultra-small ridge is in the middle of the large ridge to form a large arcuate ridge, the height of the ridge is 5 cm, between t...

Abstract

The invention relates to a crop planting technology, in particular to the planting technology for planting big rear crops in semiarid rain-fed agricultural region with high altitude but small annual rainfall. The technology of the invention is that: ditching and ploughing ridge in the leveled field, sowing seeds in side the ridge ditch after covering the ridge ditch and a ridgr platform with a mulching film. The invention, for forming the ridge platform covered by the mulching film outside the sewing ditch, can function as a water collecting surface to fully collect the rainwater and enable it flow into the ditch, thus can effectively collect rainwater and protection moisture in the soil, namely can largely reduce water loss and soil erosion as well as vaporization of moisture and sufficiently utilize the limit rainwater resource at the same time.

Description

technical field [0001] The invention relates to the planting technology of crops, especially for planting large and sparsely planted crops such as corn, potato, broad bean and oil sunflower in semi-arid rain-fed agricultural areas with high altitude and annual precipitation of 250-550mm technology. Background technique [0002] The semi-arid rain-fed agricultural area with an altitude of 2100-2400m and annual precipitation of 250-550mm has no available surface water and groundwater resources. The growth of crops depends entirely on natural precipitation. Drought is the main factor restricting local agricultural production. In semi-arid areas, precipitation is scarce, droughts occur frequently, and the distribution of time and space is very uneven. Most of the precipitation is concentrated in the three months from July to September, which is misaligned with the critical period of crop water demand. In semi-arid areas, due to spring drought, crops are often difficult to plant...
