The planting process of whole plant silage corn is basically the same as planting grain corn, but the silage corn has the botany characteristics of tall plants and lush foliage, and there are still differences in cultivation techniques. 1, sowing time Timely sowing, the actual production should be planted with grain corn at the same time, the general surface depth of 5cm at a stable temperature above 10 °C to start sowing, watch the weather forecast, the minimum temperature at night stable at 10 °C. 2, planting density A reasonable planting density not only guarantees production but also has a great influence on improving quality. The density is too large, the lodging resistance is poor, the empty stalk rate is high, the growth period is prolonged, and the photosynthesis is affected. Not only the yield is low, the dry matter content and the starch content are also low, and the quality is not good. Too small a density directly affects the biological output. General requirements for a reasonable planting density of 4000-4500 per mu, and some dense varieties can be increased to 5000-6000 strains. For flat and flourishing leaf types, the density should be low, and the density of compact leaf species can be increased appropriately; the density of high temperature accumulation and high altitude can be appropriately increased. When calculating the density, the line spacing is determined first, and the spacing is determined again. The formula is: spacing between rows = 667. 3, scientific fertilization Fertilizer quantity: silage corn has the characteristics of tall plants, lush foliage, large ear, high biological yield, more favorable to water and fertilizer, so the input of chemical fertilizer is more than 20% higher than that of grain corn, and the specific amount of fertilizer per acre is not less than 60 Kg, preferably over 70 kg, if the amount of organic fertilizer is large, the amount of fertilizer can be appropriately reduced. Fertilization method: It is better to use two fertilizers to ensure that the fertilizer is not deferred later. Nitrogen, phosphorus, and potassium fertilizers are applied as base fertilizers during site preparation. In the 8-10 leaves at the seedling stage, topdressing with nitrogenous fertilizers, it is advisable to apply topdressing urea containing potassium. The urea potassium not only contains nitrogen, but also contains potassium, which can strengthen the culm and promote the development of the ear. The proportion of top dressing is greater than the proportion of base fertilizer. The base fertilizer does not exceed 50% of the total amount of fertilizer, and top dressing is no less than 50% of the total amount of fertilizer. Foliar fertilizer can also be sprayed when conditions are met. Maize seedlings can be sprayed with 1-2 times foliar fertilizer at an interval of 80-100cm (7 days apart). Nitrogen fertilizer is the main fertilizer on the leaf surface and contains trace elements to promote growth. The effect of increasing production is more pronounced. 4, plastic film technology Plastic film cover technology is the reform of traditional production methods, which can effectively reduce the loss of soil moisture, and can effectively increase soil temperature. In areas with low rainfall, short frost-free period and low accumulated temperature, the effect of increasing production is obvious. Film coverage can increase the effective accumulated temperature of 200 ~ 300 °C, extend the growth period of 10-15 days, varieties can be extended from early to mid-early maturity, from the middle to late maturity. Each maturity period can increase production by more than 1 ton. At the same time, mulching can reduce field management links such as cultivating and weeding and reduce production costs. The whole process of pipelaying, filming, fertilizing, spraying, and sowing of the drip irrigation under the membrane can be completed at one time by the gas-suction precision film-covering machine, and the production efficiency is obviously improved.
