How to plant corn to increase production? Please suggest that the following methods of planting corn can increase production for your reference: first, planting mode 1, side film cultivation leveling the ground according to conventional planting specifications, after the film is laid, the holes are artificially opened at a distance of 3ml 5cm from the film edge on both sides of the film. 2. Wide and narrow row cultivation according to the specification of 80 cm wide row and 40 cm narrow row, covered with plastic film. 3. Intercropping in time and space can be used in intercropping. The common forms are: corn with beans, corn with garlic, corn with vegetables, corn with wheat and Chinese cabbage, and so on. 4. in order to improve the sowing density of maize, we can leave single plant and double plants in the hole on the basis of properly increasing the distance between plants. Generally, it can be increased by 500 plants / 667 square meters. Chemical control technology 1. Spraying chemical hormones such as Jian Zhuang Su, Ai Feng Su and Dipramine in the big trumpet stage to control the overgrowth of corn, reduce nutrition loss and water loss, and increase yield. 2. To promote the early maturity of corn by artificial castration, fertilizer regulation and hormone utilization. (1) artificial castration. At 3:1 in the early stage of maize flowering, the male leaves three rows and leaves one row to ensure pollination. If the remaining row is removed at the later stage, it can mature 5 days earlier. (2) applying fertilizer to regulate the growth period. The methods of seed dressing with zinc fertilizer, spraying leaves with micro-fertilizer and controlling nitrogen in the later stage can be matured 5 days earlier on the basis of early emergence of seedlings. (3) hormone utilization. In the later stage of crop growth, spraying ethephon and gibberellin on the leaf can ripen early for 5 days. Third, pest control techniques mainly introduce the control methods of red spiders: application of chemical pesticide Nisolang (1500 times, which has a strong killing effect on eggs and larvae, but no effect on adults), propargite (2000, 000 times, dissolved in warm water), acaridin (5000, 000, 000 times), 3991 granule fumigation. 4. Weed control techniques 1. Soil treatment with atrazine (atrazine, atrazine, ethyl), alachlor (Lasoo), Acetochlor, etc., sprayed on the soil surface before film mulching after sowing. 2. At seedling stage, atrazine, 2mae4 Mel D butyl vinegar and Yunongsi were sprayed on weed leaves in order to avoid contact with corn leaves. 3. Some perennial weeds can be killed by herbicides, such as Nongda, Ke Anacao Ganling, etc., and must be sprayed in a directional way (plus protective cover, low spraying). Fifth, although there is little demand for trace elements in the process of crop growth, the use of trace elements in micro-fertilizer and biological fertilizer plays an important role. As long as a little more micro-fertilizer is applied, crops can get more other nutrients at the same time. It is generally recommended to spray calcium, zinc and magnesium fertilizer on the leaves of maize at seedling stage. 6. Other techniques 1. Different harvest times should be chosen according to different planting purposes. The mature stage of seed corn is the best, the silage corn of silage is the best from the late milk stage to the early stage of wax ripening, and the harvest of sweet and waxy corn is the best at the top full warehouse. 2. Harvest method to produce seed corn can be harvested with stalk, so that the sugar content can continue to be transferred to the grain.
