| 摘 要： | 为了探索不同调控处理对晚稻机插秧秧苗生长及产量的影响,以‘H优518’和‘岳优9113’为试验材料,在大田栽培的条件下进行了用烯效唑浸种、多效唑喷雾拌种、两次叶面喷多效唑的比较试验。结果表明,晚稻品种‘H优518’和‘岳优9113’在烯效唑浸种处理下苗高、叶龄、成秧率、百株鲜重均相对较大,能显著提高机插质量,全生育期缩短1天,干物质重量最大,产量最高分别为7354.5 kg/hm~2和7236 kg/hm~2。多效唑喷雾拌种的处理产量次之。两次叶面喷多效唑的处理茎基宽最大,但全生育期延长1天。综合来看,烯效唑浸种处理最有利于培育健壮的晚稻机插秧秧苗,提高插秧质量,缩短生育期,保证机插秧产量,有利于水稻机械化栽培。

| Abstract: | In order to explore the effects of different regulating treatments on the growth and yield of rice transplanterseedling,Hyou 518 and Yueyou 9113 were used as experimental materials, and seed soaking with uniconazole, seed dressing with paclobutrazol and spraying with paclobutrazol twice under field cultivation conditions.The results showed that late rice varieties Hyou 518 and Yueyou 9113 had higher seedling height, leaf age, seedling rate and fresh weight per hundred seeding, and could significantly improve the transplanting quality. The whole growth period was shortened by one day, the maximum dry matter weight, the highest yield were 490.3kg/667m2 and 482.4kg/667m2. The yield of paclobutrazol was the second. The treatment of paclobutrazol with two foliage treatments had the largest stem width, but the whole growth period was prolonged for one day. In conclusion, the seed soaking treatment of uniconazole was the most beneficial to cultivate strong late rice transplanter seedling, improve transplanting quality, shorten the growth period and ensure the machine transplanting yield, which is good for mechanized rice cultivation. |
