摘要
[目的]探讨机插单季晚稻秀水134适宜的播栽期和密度。[方法]分别进行播期试验、栽插期试验、播种量试验和栽插密度试验,分析播栽期和密度对机插单季晚稻秀水134的影响。[结果]适期分批早播、稀播,适龄早栽有利于取得足穗、大穗、高产。足丛密植有利于足苗、足穗、高产。浙北地区单季晚稻秀水134机插,以5月中旬至下旬分批播种,播量125～150g/盘,栽插秧龄15～20d,密度27万～25万丛/hm2,基本苗100万～150万/hm2为宜。[结论]研究结果为单季晚稻秀水134生产提供了参考资料。
[Objective] The aim was to study suitable sowing and replanting date and density of maehine-transplanted single late rice Xiushui 134. [Metbod] The effects of sowing and replanting date and density on machine-transplanted single late rice Xiushui 134 were analyzed by taking experiments on sowing date, transplanting date, seeding rate and planting density. [Result] Optimal early sowing and sparse-seeding in batch, transplanting at optimum seedling age were beneficial to get enough ear with a high yield. Close planting with enough cluster was beneficial to get sufficient plants and enough ear with a high yield. Single late rice Xiushui 134 should be machine-transplanted with following technical conditions： batches sowing in late May, sowing rate of 125-150 g/Plate, seedling age of 15-20 d, planting density of 27×10^4-25×10^4 eluster/hm^2. [Conclusion] The results provided reference information for the production of single late rice Xiushui 134.
