1. Reasonable close planting. The suitable density of high oil corn is 4,000 to 4,500 plants per mu. In order to reduce the empty rod and improve the group uniformity, the number of emergence should be about twice the suitable planting density; during the period of 4 to 5 leaves, the number of seedlings should be 1.3 to 1.5 times of the suitable planting density; The upper limit of the appropriate planting density should be used. The silking stage can be combined with auxiliary pollination to weak plants, and empty stalks can be eliminated to ensure a uniform group.

2. Scientific fertilization. In order to promote plant growth and increase grain weight and oil content, nitrogen, phosphorus and potassium fertilizers should be added. Generally, 1000 to 2000 kg of organic fertilizer per mu, 8 kg of phosphorus pentoxide, 8 to 10 kg of nitrogen, 1 to 2 kg of zinc sulfate, 2 to 3 g of nitrogen fertilizer during seedling stage, and 5 to 7 days after jointing. Apply 10 to 12 kg of nitrogen fertilizer.

3. Chemical regulation. High-oil corn plants are usually 2.5 to 2.8 meters high. Controlling high-resistance is one of the key measures for planting high-oil corn to achieve high yield. Generally, 30 ml of corn can be sprayed per acre during large flare period, or A new growth regulator, Vitalin, is sprayed per acre during the large flare period.

4. Timely treatment of pests and diseases. High-oil corn has strong resistance to large-scale spot disease, but the incidence of corn borer is higher. The prevention and treatment method can be used in the large bell mouth period with 3 to 5 kg of mites, or 3 kg of chlorpyrifos, or 2 kg of 1% of carbofuran granules. In the high-incidence area, it can be applied to the pistil once again during the silking period, which can effectively reduce the loss of bamboo shoots and ensure high yield and good harvest.
