Corn planting technology: corn planting technology video picture

The main results are as follows: 1. Soil preparation and fertilization must be done in soil preparation, deep ploughing and careful cultivation to avoid uneven seedling emergence; more than 2000 kilograms of farm manure, 20 kilograms of phosphate fertilizer and 20 kilograms of carbon amine are applied per mu. 2. Sowing corn at the right time: it should be isolated from other corn. Before sowing, the seeds must be sterilized: soak in clear lime water or soak in 50% carbendazim 500 times solution for 7 to 8 hours before sowing or budding. Spring sowing from March to April and summer sowing from June to July. The suitable strip sowing method is that the row spacing is 83 cm, the plant spacing is 30 cm ~ 40 cm, the seed per mu is 1.5kg, and 3000 ~ 3500 plants per mu. It is best to use plastic film mulching or seedling transplanting for early planting. 3. Replenishing seedlings of maize: check the situation of seedlings in time after emergence, and if there is a lack of seedlings, soak seeds in time to promote bud replanting. 4. Topdressing corn in time: at 4 leaves, 2000 kg of manure water and 5 kg carbamine per mu were used to top up the seedling fertilizer; at jointing, 25kg rapeseed cake or tung oil cake plus 2.5kg urea was applied and cultivated to weed the soil; when 9 leaves, "bract fertilizer" was applied, and urea was used for 12.5kg per mu. Pest control is the same as ordinary corn. 5. Corn should be harvested in time: the harvest time is generally 18-23 days after pollination, when the grain water content is about 70%. When the corn is harvested, the corn cobs and bracts are broken off together; after harvest, they are sold or processed in time.
