The corn micromembrane cultivation technology has the advantages of improving the ecological environment, shortening the growth period, early maturity, and alleviating the contradiction of labor crowding during the farming season. However, there are some problems in the implementation of this technology. According to the current production situation, the following points should be noted in the implementation of corn microfilm cultivation: First, open the fertilization ditch or digging the fertilization nest and pay attention to the problem of fertilization. Flat soil open fertilization ditch or fertilization nest, slope soil digging fertilization nest, ditch and nest must be loose. Fertilization from high to low, both the ditch and the nest must be slowly poured into the ditch or nest. Immediately after the application, the soil is covered and the nest is covered to prevent the loss of fertilizer and evaporation. Second, planting attention problems. First, the soil must have enough sensation. Second, the soil surface should be level. Third, the seeds of the live broadcast must be soaked in germination. Fourth, when the bud is 2-3 mm long, the seed size and the length of the buds are roughly the same. Seeds are sown, and each nest is 2-3 pieces. It must be 10-20 cm away from the fertilization ditch or the fertilization nest to prevent the fertilizer from damaging the seeds. Or hurt the seedlings. Fifth, immediately after the end of the sowing, the ball is raised and raised for seedlings, and one seed is sown per ball. When the seedlings are 3-4 leaves, they are transplanted in the place where the seedlings are missing. Third, the cover film Note: In case of soil drought, after the rain, there is enough sensation cover film or conditional place to water to reach enough sensation cover film. The herbicide applied before the cover film should be on the road, the spray should be uniform, not excessive, and the film should be covered for half an hour after application. The micro-film should be covered on the soil surface of the seeding or planting area, and it should not be offset. The soil around the micro-film is pressed tightly to protect the moisture and reduce the weed growth. Fourth, do a good job of membrane rupture and seedling emergence: seedlings unearthed and have a leaf from one heart to two leaves when the membrane is introduced into the membrane. At the same time, the soil and the seedlings are moved, and the seal is severely broken, once every other day until the emergence of the seedlings. 5. Seedling transplanting: When the corn seedlings are from three leaves to three leaves, they are transplanted. It should be transplanted according to the size of the seedlings. When transplanting, do not plant it on the ditch or nest of fertilizer, away from about 15 cm. Strive to plant deep points, and then move the soil to the stems of the seedlings and seal them tightly.
