In recent years, all regions have vigorously promoted corn film mulching techniques, which has played a significant role in increasing corn production and increasing farmers’ income. However, some problems were found in the promotion, mainly in several aspects: It is easy to form punching holes on the conjunctiva. When it rains after sowing, it is easy to form agglomerates. It is difficult to break the knots, causing difficulty in the emergence of corn. It is easy to form seedlings and breaks. Low rainwater utilization rate covers the groundwater film and has good water retention performance. However, in case of light rain, rainwater diverts from the mulch to both sides of the mulching film. Since there is little rainwater, it cannot penetrate into the under film, and there is less moisture infiltrating the rhizosphere, and the corn root system can not obtain sufficient moisture. To make part of the rain evaporated. It is difficult to remove the film when the corn grows late, when it encounters high temperature and drought, or before and after harvesting, when it is necessary to peel off the plastic film, corn is planted on the plastic film. When the film is peeled off, it is difficult to remove the film and it is difficult to peel off the film. Workmanship. Farmers with a relatively shortage of labor cannot implement the removal of the film. The late high temperature and drought will result in insufficient grain filling, which will affect the increase of yield. Soil pollution caused by the lack of rural labor, coupled with the increase in the degree of agricultural mechanization, corn straw is basically used to return to the field at one time, while returning the field, the film will be left behind in the soil, resulting in white soil pollution, to feed The normal growth of crops has a certain effect. For these defects of mulching corn, after many years of practice and exploration, we have summarized the planting mode of sowing on the side of the film. In the production, we have achieved very good results in increasing production and are welcomed by farmers. The membrane side planting mode has the following advantages: Raising the ground temperature We measured the ground temperature of corn at 10 cm before the jointing of corn. The exposed ground temperature sown on the membrane side was higher by 1.4°C-1.8°C, which was 0.2°C-0.4°C lower than that sown on the membrane. By raising the ground temperature, the seeds can be planted 7-10 days earlier, and the seedlings grow fast and robust, laying the foundation for high yields. To prevent the formation of rain after sowing, generally does not form a knot. Even if there is partial consolidation, breaking is very easy. It can promote the emergence of corn with neat seedlings, seedlings and seedlings. At the same time, it has reduced the waste of human resources caused by the elimination of consolidation and reduced the labor burden on farmers. There is less rain in spring water storage, but in the event of rain but not in the sowing period, the mulch can be laid in the field manually or mechanically to protect the bottom. At the time of sowing, the seeds of the mulching corn can be sown on each side of the film. After sowing, it was light rain. The rainwater diverted to both sides along the mulch, just irrigating the roots of the corn, partially infiltrating under the plastic film to preserve it, prolonging the water use time, and satisfying the demand for water for a long time. Make corn grow and develop robustly and gain high yields. It is favorable to top-dressing corn like top-dressing, and top-dressing has a great impact on the yield. After several years of trials, each time the fertilizer is chased once during the jointing stage and the big bell-mouth period of the corn, the yield can be increased by about 200 kilograms. Therefore, in the event of rain, it can be manually or mechanically applied by acupuncture or applying methods, and the top dressing depth should be 7-10 cm. The maize fertilizer sown on the film side was closer to the root system of corn than that planted on the film, which was beneficial to absorption and utilization. Easy to remove the film, because the film side sowing, uncovering the film from the stalks and root defects, it is easy to peel off. When the high temperature and drought occurred in the later season or before and after harvest, the mulch can be removed (as long as the mulch is of good quality, it can be uncovered once). And it saves labor and time, leaving no residue. It not only solves the influence of high temperature on corn in the later period, but also solves the problem of soil pollution, and does not affect the growth of the crop under cultivation.
