Study on Water-saving and High-yield Technology of Drip Irrigation under Corn Film
Corn film irrigation technology can achieve water saving, production and production increase. After years of experiments, this advanced technology has gradually matured, which has important significance for the improvement of corn production in China. Next, let's take a look at the technology of drip irrigation and water saving under the corn film. 1. Brief introduction of sub-membrane irrigation technology Sub-membrane irrigation technology, in simple terms, is a technique in which a layer of mulch is covered in the field and irrigation is carried out under the membrane to achieve water conservation, production and production. This irrigation technology effectively combines the cultivation technology of the mulch film and the drip irrigation technology, and is an efficient and rapid drip irrigation technology. In the irrigation process, according to the growth conditions and actual needs of different crops, the drip irrigation system is used to transport the water to the space that the crop can absorb. This irrigation method mainly acts on the root crops, and the drip irrigation is not only water, but also drip irrigation. Pesticides and fertilizers, etc., thereby eliminating viruses, supplying nutrients needed for crops, and improving the quality and yield of crops. This irrigation technique requires reasonable control of the replenishment of water and fertilizer to provide maximum nutrient nutrition. Under-film drip irrigation technology can significantly save water and increase production. After mulching on the soil, the evaporation of water will be greatly reduced. After the water is mixed into the soil, the salt can be fully dissolved and the salt can be spread around. Leave a salt-free area in the center that is good for crop growth. This method can directly irrigate water and fertilizer. Due to the obstruction of the mulch film, it is difficult for water and fertilizer to penetrate into the ground or be lost due to surface runoff. The flow space of water and fertilizer is basically controlled in a relatively closed space, in which space can promote the photosynthesis of crops. Maximize the effect and achieve the ultimate goal of increasing production and maintaining value. In addition, under-film drip irrigation technology has the advantages of automatic management. 2. Corn film under irrigation high yield technology Corn under-film irrigation technology is a special application of sub-membrane irrigation technology. In the field, pipelines are laid along the direction of corn planting. Pipes must have drip heads and small holes to facilitate the transportation of water and nutrients. During the irrigation process, the water source should be transported to the surface of the soil intermittently or continuously. This way, a thin film is applied to the pipeline. This technology is an important achievement in the research of corn planting technology. It is a comprehensive application that can integrate heat preservation, water saving, yield increase and drought resistance. In the application of corn planting technology in Daqing, the accumulated temperature is more than 200 degrees, and the number of seedlings is about 5,000, and the yield per acre is nearly 1000. Compared with the common planting method, this method can increase the income per mu by more than 500 yuan, which can save About 40% of water and about 35 percent of fertilizers are saved. Corn growers do not need to weed and turn the ground, which greatly saves planting costs and achieves a combination of economic and social benefits. There are infinite possibilities. 3. Research on drip irrigation technology under film in Daqing City 3.1 Depending on local conditions The cultivation of corn should be adapted to local conditions. The drip irrigation technique under the membrane is also the same. Before the planting, the geological survey should be carried out. It is best to choose the terrain with flat terrain, soil fertility and convenient irrigation to ensure the success of the drip irrigation technology under the membrane. The texture of the soil should be soft, and the ability to retain water and fertilizer should be strong. Pay attention to the application of the base fertilizer. The base fertilizer has an important impact on the yield of corn. Under normal circumstances, the application range of the base fertilizer is below 0.1 m on the soil surface, and the drip irrigation technology only Responsible for watering, unable to water the soil, in the case of drip irrigation technology, it is necessary to rationally apply base fertilizer to increase the utilization rate of base fertilizer. In the spring, it is necessary to carry out land preparation, and apply about 2,000 kilograms of organic fertilizer per acre. In the process of land preparation, the degree of soil loosening can be ensured. The depth of tillage is preferably about 30 cm, which can also ensure the permeability of the soil. Promote the absorption of fertilizer. The land preparation should follow the six-character slogan, “flat, clean, loose, broken, Qi, 墒â€, in order to effectively ensure the quality of the soil, improve the efficiency of drip irrigation technology, and achieve a bumper harvest of corn. 3.2 Seed selection and processing The under-film drip irrigation technology of corn can promote the development and maturity of corn in advance, so it is necessary to select suitable seeds for planting. Do not choose seeds with premature maturity in the selection of seeds. Consider the varieties with longer growth period, which can increase the yield. The best choices are the seeds of Xianyu 335, Tianfa 502 and 503 series. Such seeds are more suitable for drip irrigation technology under the membrane. In the treatment of seeds, the first germination test is to be carried out. In the sowing process, seeds with low germination rate should be selected as much as possible. After drying, the seeds can be sterilized and disease-proof, and the quality of seeds can be improved. In areas where the soil has a high moisture content, seeds can also be soaked, and the seeds can be germinated, and draining and sowing can improve the quality and yield of the corn. Finally, there are seed coating, stuffing and seed dressing. If necessary, the coated seeds can be directly selected for planting. The process of germination cannot be carried out, which may cause phytotoxicity. 3.3 with hoe sowing, closed weeding Under normal circumstances, the drip irrigation under the corn membrane begins the first sowing on April 10, the second sowing is postponed for five days, and the third sowing is postponed for about thirteen days. The form of sowing can be selected with sorghum sowing, which not only promotes the growth of corn, but also promotes the development of the roots of corn. Under-film drip irrigation technology can be divided into artificial and mechanical operation modes. The planting methods are mainly divided into single-ridge planting, large-row double-row planting, and large-ridge mixed planting. The double-row planting of large ridges adopts the “one tube and two rows†irrigation method, which can maximize the planting effect. After planting, we can use 90% of Herne's emulsifiable concentrate or 72% of Duer's herbicides to remove weeds. When spraying, we must pay attention to keeping the soil moisture. Pesticide is sprayed in a closed space by means of drip irrigation to prevent weeds from affecting corn yield. At the same time, we must pay attention to the management of the field, protect the mulch film, and properly control the external objective factors to ensure the corn production.
