水稻旱育壮秧稀植技术较好地解决了水育秧的烂秧和秧苗不壮两大难题,具有省水、省种、省工、省肥、省秧田、增产、早熟等优点。旱育秧苗矮壮,根系发达,返青快,分蘖早,成穗多。合理稀植,扩大行距,减小墩距和墩苗数,更利于增加水稻有效分蘖,提高成穗率,减少病虫害发生,具有明显的增产效果。技术推广过程中产量和效益增加明显。技术要点1.选用良种。选用优质、高产、抗逆性强、增产潜力大、综合性状良的中
The technology of sprouting seedling and sprouting in paddy rice well solves the two difficult problems of rotting seedling and seedling of watering seedling, which has the advantages of saving water, saving species, saving labor, saving seedling, raising seedling, increasing yield and precociousness. Dry seedling seedlings sturdy, developed roots, fast green, tillering early, into more than spike. Reasonably thin planting, expanding row spacing, reducing pier spacing and the number of pier, but also help to increase the effective tillering of rice, increase the rate of spike, reduce the occurrence of pests and diseases, with obvious yield-increasing effect. Technology promotion process output and benefits increased significantly. Technical points 1. Selection of elite. Selection of high-quality, high yield, resistance to strong, large potential for production, a comprehensive good trait
