1. Sowing by stages: Sowing by stages and listing by stages, which can be advanced or postponed. Nursery in shed or hotbed can be planted in late February. Direct seeding cultivation with plastic film mulching can be sown in early March, direct seeding in the open field can be started in early April, and can be sown until the middle and late July, forming a continuous supply period from June to 10.
Second, optimize improved varieties: semi-compact varieties such as Sunuoyu 1, Yandan No.5 and Lunuoyu 1 are better.
Third, isolated planting: when planting waxy corn, it should be isolated from other types of corn. Isolation can adopt spatial isolation and time isolation. The use of space isolation is generally at least 200 meters; Time isolation means that the sowing dates of other types of corn are staggered, so that the planted waxy corn is not "beaten" by other types of corn nearby. Generally, the interval between spring sowing and summer sowing is about 30 days and 20 days respectively.
4. Reasonable close planting: planting with a width of 0.8 ~ 0.9 m and a narrow row of 0.4 ~ 0.5 m, and it is better to keep two seedlings. Semi-compact hybrid varieties such as Yandan No.5 and Sunuoyu 1 should be planted with 4000 ~ 4500 plants per mu, while flat hybrid varieties such as Lunuo 1 should be planted with 3500 ~ 4000 plants per mu. Spring sowing is slightly sparse and summer sowing is slightly dense; Fertile land is slightly denser and barren land is slightly thinner.
5. Clever fertilization: before sowing, apply manure 1000 kg per mu, and use 30-40 kg of compound fertilizer as base fertilizer; Topdressing urea at seedling stage, jointing stage and heading stage was 2-8kg, 3-5kg and 6 6- 10/0kg respectively.
6. Pay attention to pest control: waxy corn is more seriously damaged by corn rot and armyworm than ordinary corn, so pay attention to prevention and control. The control effect of corn cob and armyworm with 2.5% cypermethrin EC or 20% metronidazole EC 1500 ~ 2000 times solution is better.
Seven, timely harvesting: when harvesting has a great influence on the quality of waxy corn green ears. Early harvest, insufficient dry matter and various nutrients, low yield; When the harvest is too late, the seeds shrink, the epidermis becomes hard and thick, and the taste is not good. 25 ~ 30 days after pollination is the suitable harvest period for fresh waxy corn ears.
