Due to late sowing, delayed seedling development, too small C/N ratio, malnutrition, and other factors affecting the growth and development of corn, vegetative overgrowth and delayed reproduction are known as late-maturing. Late maturity of the glutinous corn has delayed ripening, serious plant diseases and insect pests and lodging, and reduced yield. In addition, cross-regional introduction, blind introduction, the use of late-maturing varieties, will also cause corn can not be normal maturity, reduced or even out of production, quality decline.
Management techniques include:
1. Choose appropriate breeds and suitable planting techniques for the growth period.
2, timely sowing, sowing time not later than the recommended sowing date. Timely seedlings, promote early development. Potassium fertilizer was added, and potassium dihydrogen phosphate was sprayed in the middle and later stages; nitrogen fertilizer input was reduced in the middle and later stages.
3. Remove empty stalks and small plants and knock down the bottom leaves.
4. After the grouting is completed, the loquat leaves are peeled off to promote the ripening of the grains. Harvest with stalks to promote after-ripening.
