[0020] 1 Materials and methods.
[0021] Test location: The research test on the relationship between water vapor transmission rate and yield of mulch film was carried out in Wutong Village, Shangxiao Town, Zhenyuan County, Qingyang City, Gansu Province from 2019 to 2020. It is located at 107°39′E, 35°30′N, Haibo 1279 m, the annual average temperature is 8.3°C, the average annual precipitation is about 530mm, of which the precipitation from July to September accounts for more than 60% of the annual precipitation, the annual evaporation is about 1580mm, which is three times the annual average precipitation, and the accumulated temperature ≥10°C 2750°C, a semi-humid and dry continental monsoon climate in the warm temperate zone, which is a typical rain-fed agricultural area.
[0022] The cultivation experiment was carried out in Xujiazhuang, Yuzhong County, Lanzhou City, Gansu Dry Farming Area. It is located at 104°10′E, 35°51′N, 1740m above sea level, with an average annual tem...

Abstract
The invention relates to a spring corn planting method realizing mulching film sustainable composite covering. The method is characterized by comprising the following steps of S1, seed selection; S2, mulching film selection; S3, fertilizer preparation; S4, deep ploughing and soil preparation; S5, preparation before sowing, specifically, dividing the land into a plurality of rows of biodegradable mulching film covering areas and a plurality of rows of high-standard polyethylene mulching film covering areas before mulching film covering, wherein each row of biodegradable mulching film covering areas and each row of high-standard polyethylene mulching film covering areas are alternately arranged, a fertilizer is spread on the biodegradable mulching film covering areas, acetochlor is sprayed on the biodegradable mulching film covering areas for under-film weed prevention; during mulching film covering, it is guaranteed that the edges of biodegradable mulching films and the high-standard polyethylene mulching films are overlapped, and the edges of the high-standard polyethylene mulching films are located above the edges of the biodegradable mulching films; S6, seed sowing; S7, field management; and S8, high-standard polyethylene mulching film recycling. By means of the planting method, the use amount of the fertilizer and mulching films can be greatly reduced, and the labor cost for planting spring corn is reduced.
Description
technical field [0001] The invention relates to the technical field of agricultural planting and specifically designs a method for sustainable composite mulching planting of spring corn. [0002] technical background [0003] Moisture and temperature are the limiting factors for agricultural production in dryland areas. Water resources in dryland areas are severely scarce, and precipitation is unevenly distributed between years. The dry climate causes a large amount of water in the soil to evaporate. Polyethylene mulch plays an important role in regulating soil temperature and preserving Precipitation, suppression of soil water loss, and suppression of weeds have excellent performance and important functions. Therefore, plastic film mulching technology has become an important driving technology to promote the development of agricultural production in dryland areas. However, the good physical and chemical properties of polyethylene mulch gradually show negative effects in the ...
