About, the experts pointed out that in 2018, the spring corn planting technology is simplified, and Huinong.com has only compiled the general (grain) corn planting technology for everyone. The following continues to introduce the corn planting technology and sweet and waxy corn planting technology.
I. Feed corn planting technology
1 Promote order production and guarantee production income
It is recommended to plant in the vicinity of a large dairy farm or silage, which is advantageous for sale and easy transportation.
2 selection of the variety
It should be selected as an excellent silage corn variety or a grain-feeding variety that has been approved, suitable for planting in the region, with a growth period of 110 to 120 days, strong resistance to large and small spot diseases, and green ripening.
Suggested trials: Bencheng 6 (Pencheng 6), Hongrui 101 (Hongrui Silage 101), Jinshang 100, Agricultural Research Silage 2, Yufeng 185 (Suiyu 308), Zheng Dan 958, etc.
3 planting density
Generally, the seedling density is 4,500 to 5,500 plants/mu, which is higher than that of ordinary corn.
4 Pest control
Prevention is the main, prevention and control measures move forward. It is strictly forbidden to use highly residual highly toxic pesticides during the whole growth period. Stop using pesticides within 15 days before harvesting, and use physical and biological control to control pests and diseases.
5 harvest period
At the end of the milk maturity of the grain to the early stage of the harvest, and timely silage treatment, the harvest can obtain the best value of yield and nutritional value. Other cultivation measures are the same or similar to ordinary corn.
Second, sweet, waxy corn planting technology
1 Promote order production, properly concentrate planting, and guarantee production income.
2 selection of the variety
You should choose an excellent variety that has been approved, localized for disease-resistant and high-yield, and harvested from 80 to 90 days.
Recommended varieties, glutinous corn can be tested: Wanhao 2000, Jingke 糯 2000, Caitian 糯 2, etc.; sweet corn can be tested: Boss sweet 818, Wan Tian 2000 and so on.
3 batch seeding
In particular, self-produced and self-selling farmers should adopt batch seeding, batch harvesting and sales, to avoid the difficulties of harvesting and sales caused by concentrated maturity.
The mulching film covers the sowing of sweet corn, which can be planted in the early days until April 10, and can be taken on the land after April 20.
Sweet corn seeds are small (瘪), the seeding depth should be 2 cm ~ 3 cm, so as not to affect the emergence of seedlings.
4 isolation planting
It is spatially isolated from other corn varieties by more than 400 meters; or by time isolation, that is, the sowing date of other corn varieties grown in the adjacent and surrounding areas is different from 20 days to 25 days to ensure quality.
5 pest control
Take prevention as the main, prevent and control measures move forward, and give priority to physical control and biological control.
Chemical control shall be carried out in accordance with the pollution-free agricultural product management regulations or green food production standards, using high-efficiency and low-residue pesticides, and it is strictly forbidden to use high-residue highly toxic pesticides during the whole growth period.
Stop using pesticides within 20 days before harvesting, and use physical and biological control to control pests and diseases.
6 best manual weeding
Many sweet, waxy corn varieties are sensitive to herbicides. Improper use is prone to phytotoxicity. It is best to use manual cultivating and weeding. Chemical weeding can not spray herbicides containing nicosulfuron, and it is necessary to select a test before it is effective and harmless.
7 Reasonable close planting
The density of seedlings is thinner than that of ordinary corn, and generally 3,200 to 3,500 plants per mu.
8 timely harvest
The harvesting standard for waxy corn is: the grain water content is about 50%, generally harvested 24 to 26 days after silking; the sweet corn harvesting standard is: the grain water content is 66% to 71%, generally 20 to 22 days after corn silking. Harvested. Strive to achieve the same day harvest, processing the same day, to ensure the quality of fresh food. Other cultivation measures are the same or similar to ordinary corn.
