Special corn cultivation and management

First, fresh corn cultivation management:

1, the choice of varieties: should choose good quality, comprehensive resistance, adapt to the regional market sales.

2. Isolation: In principle, time, space, and obstacle isolation methods are used. Fresh corn should be separated from other corn varieties by more than 300 meters, so as not to affect the quality of string powder, and the natural barrier distance can be appropriately shortened; time isolation must be more than 20 days above the flowering date of other corn varieties.

3, preparation before sowing, sowing seeds before sowing can improve germination; choose flat land fertile, adequate light, irrigation and drainage conditions, Mushi organic fertilizer about 1500 kg, 40 kg of phosphate fertilizer, 40 kg of compound fertilizer, 15 kg of potassium fertilizer ( Potassium chloride or potassium sulfate).

4, sowing time: in principle, the earliest sowing to the soil surface in the depth of 5 cm stable ground temperature above 12 °C, the latest seeding must be 100 days before the arrival of early frost. Except special sowing requirements. The use of mulch film covering, seedling transplanting and other methods can be appropriately sowed in advance, the same plot requires a consistent sowing date, otherwise it will affect the Miao Qi and harvest period.

5, seeding rate, the use of species per acre is generally 1.5-2.5 kg, 1 or 2 per hole in advance or postponed appropriate amount of increase and decrease, sowing depth of 3-5 cm, sweet corn grain shrinkage, young shoots top soil ability, Shallow broadcast should be appropriate.

6, field management: when sowed or coated with poisonous flour powder to control the underground pests, the density of planting depends on the variety, general sweet waxy corn 3000 per mu, bamboo shoots 5000-5500 / acre. The jointing to filling stage is the critical period of water demand, combined with irrigation to replenish primary fertilizer, and mainly quick-acting nitrogen, which can greatly increase production. After years of experiments, it has been shown that multiple application of biological fertilizer can effectively improve the soil, increase the yield and quality, promote the early maturation of crops, and enhance Disease resistance and disaster-resistance are relatively intuitive manifestations of full fruit, bright color, and increased sugar content.

Harvesting period: Harvesting of corn shoots during the spikelet spinning. About 72% water content of sweet corn grain was the best harvesting period, generally 20 days after pollination; fresh corn was harvested 20 to 25 days after waxy corn pollination. After harvesting, it is timely processed and the straw is harvested 5-7 days after harvest to prepare for comprehensive utilization.

Second, feed corn cultivation management:

1 stage sowing, in order to extend the supply of green feed, can be sowing time, the interval is 15-20 days. Hand broadcast 2 kg/mu. When machine broadcast 3 kg/mu. Due to the instability of branching, sowing at high temperatures, the branching is weakened, and the amount of sowing should be appropriately increased in summer sowing. 2Increase the density, the row spacing is generally 60 centimeters and 25 centimeters, the north mu leaves the seedlings to 4000-5000, in the south of the Yangtze River due to the reduction of branching, the Mu Liumiao is 7000-8000; this species has the branching characteristics, when the seedlings Can't go to branch. 3 fertilizer and water is sufficient, due to the growing density of forage corn, fertilizer and water requirements are very high, base fertilizer applied 5000 kg of organic fertilizer per acre, but also appropriate to increase nitrogen, phosphorus, potassium fertilizer, especially potassium fertilizer. Soil cultivators are to be cultivated before sealing, which will facilitate irrigation and drainage, increase lodging resistance, and timely irrigation during the jointing stage to obtain higher forage yield. (4) Harvesting in appropriate period, the best harvesting period of silage corn is generally around 40 days after pollination, ie the late stage of milk ripening and wax initial stage of grain growth. Early harvesting will affect yield, too late harvest, yellow leaf increase affect quality .

Third, burst corn cultivation management:

1 It is due to the fact that popcorn grains are small, and the emergence is slow, and fine seeding is required; 2 is that most popcorn varieties have the feature of outcrossing sterility, that is, the filaments can only receive fertilization and fertilization of their own or the same species of pollen, granting other types of corn After the pollen, it is shown that the outcrossing is not strong, so it does not need to be isolated when planting. 3 is harvested at the ripening stage, because the popcorn of popcorn can only be processed into the popcorn with the maximum bursting coefficient after the mature corn is fully matured.
