目的探索机插杂交籼稻稀播育秧秧苗生长特性、栽插质量、产量与效益特点。
Objective Our purpose is to investigate the rice seedling growth characteristic, quality of transplanting, rice yield and economic benefits of sparse seeding in indica hybrid rice.
所以，适当稀播可以培育壮根，增强根系活力，充分发挥土壤、特别是深层土壤的作用。
Therefore, properly sparse-sowing was favourable to cultivate strong roots, increase root activity and bring the yield-increasing function of soil, especially of deep soil into full play.
应用以抗病品种为主、增施钾肥、适期晚播、适当稀植等农业栽培综合防治措施。
High K fertilizer application could increase the resistance of corn and decrease the disease incidence.
