五月插秧季节,平均气温14～16℃。土温17℃左右。如遇苗弱地瘦,插秧时缓苗期一般需要5～7天,甚至更长。实践表明,水稻插秧前用速效性化肥(氮肥、磷肥)作基肥,对促进缓苗,早生快发,争取农时,提早成熟,实现高产稳产有良好的效果。全层施肥是在耙地前,利用畜力或动
May planting season, the average temperature of 14 ~ 16 ℃. Soil temperature about 17 ℃. In case of weak to lean, seedlings when transplanting seedlings generally take 5 to 7 days, or even longer. Practice shows that the use of quick-acting chemical fertilizers (nitrogen and phosphate) as basal fertilizer prior to rice transplanting has a good effect on promoting seedling emergence, quickening early and quicker hair growth, getting early maturity and achieving high and stable yield. Full-layer fertilization is in the harrow before the use of animal power or move
