Jingnongyu 658 has developed root system, stout stem, strong lodging resistance, strong ground breaking ability, vigorous seedling vigor, uniform maize seedlings and medium and high yield. Generally speaking, corn can be sown in April. Before sowing, compact maize varieties with strong disease resistance, high yield and lodging resistance should be selected and the seeds should be treated. After sowing, water and fertilizer should be applied according to the growth of corn, and intertillage weeding should be carried out to make corn grow better.

1. Introduction Experiment of Maize Variety Jingnongyu 658

1 and Jingnongyu 658 maize seedlings are uniform, with strong soil-breaking ability and vigorous seedling vigor after sowing.

2. This variety has developed roots, stout stems, strong lodging resistance, no sharp points and no seeds under high temperature and high heat environment, and the quality and yield of corn produced are above average.

Second, how to plant corn

1, seed selection and treatment

It is necessary to select compact maize varieties with strong disease resistance, high yield and lodging resistance, and screen out high-quality and full seeds. Seeds need to be dried, coated and soaked before sowing.

Step 2 sow seeds

Generally, sowing can be done in April, and the appropriate sowing method can be selected according to soil fertility. For example, in low fertility soil, equal row spacing is usually used, while in fertile areas, corn can be planted in a combination of width and width to make full use of soil fertility and improve corn yield.

3. Water and fertilize

Corn needs a lot of water, so water it according to its growth. In view of the relatively weak growth of corn, it is necessary to supplement urea and phosphorus and potassium fertilizer in time to effectively improve the growth rate and yield of corn.

4, intertillage weeding

In order to improve soil permeability and reduce the source of soil diseases, intertillage and weeding should be done in time to improve the growth quality of maize and make it fuller.

5, pest control

Common corn diseases and insect pests include smut, leaf spot, stem rot, gray spot, blue mold, aphid, corn borer, etc. Different control measures should be taken in time according to different diseases and insect pests. For example, 500 times solution of 75% chlorothalonil wettable powder can control gray spots, and 70% thiophanate-methyl ultrafine wettable powder 1000 times solution can control Penicillium ear rot.
