水稻旱地播种育秧,耐寒力增强、根系发达、生长优势明显、增产效果显著,同时可适当提早播种,避灾增产效果好,值得在水稻生产中推行。一、旱秧可早播早抽穗,避灾增产效果好 1.旱育早播,优于温室秧避灾效果旱育秧比水育秧可提早15—20天播种。我市中山区水稻播期为3月底至4月初,旱秧则提早到3月中旬,抽穗期比地膜水
Rice sowing seedlings in the dry land, cold hardiness, developed root system, obvious growth advantages, yield significant results, and appropriate early sowing, disaster prevention and yield increase effect is good, it is worth promoting in rice production. First, dry seedlings can be early sowing early heading, good effect of disaster prevention and control 1. Drying and early sowing, better than the greenhouse seedling disaster prevention and drought-tolerant seedlings than aquatic seedlings can be planted 15-20 days earlier. Zhongshan City, sowing date of rice for the end of March to early April, early drought to early March to mid-March, heading than the plastic film water
