在灵山县生态条件下,对早、晚稻免耕抛秧的适宜抛栽密度进行了研究。结果表明,早稻免耕抛栽密度不应少于33.0万~34.5万蔸/hm2,晚稻免耕抛栽密度以34.5万~36.0万蔸/hm2较理想。
Under the ecological conditions of Lingshan County, the suitable throwing planting density of no-tillage and throwing seedlings for early and late rice was studied. The results showed that no-tillage and early sowing throwing planting density should not be less than 330,000 ~ 345,000 蔸 / hm2, no-tillage sowing late rice planting density 345,000 ~ 360,000 蔸 / hm2 more ideal.
