摘要： 为探索温岭市早稻的适宜播种期和机械移栽方式,开展早稻不同播期下钵苗摆秧及毯苗机插的对比试验。结果表明:早稻钵苗处理的抗性、生产稳定性要明显好于毯苗,播种期可以比毯苗提前10~15 d,最佳播种期为3月1日;早稻钵苗处理的成熟期比毯苗提早3~6 d,比直播早稻成熟期提前7~10 d;早稻生产中,钵苗带土无植伤移栽有利于活棵发苗,与毯苗移栽相比,有10 d的早发优势,栽后15~20 d是分蘖爆发期,分蘖多为低节位有效分蘖,易成大穗;相同播种期下,早稻钵苗摆栽比毯苗机插有增产优势,增产主要是钵苗活棵早发带来的穗多、穗大和粒多。

Abstract:

To explore the suitable sowing date and mechanical transplanting method for early rice in Wenling City, a comparative experiment was conducted on bowl seedling machine transplanting and carpet seedling machine transplanting under different sowing dates of early rice. The results showed that the resistance and production stability of bowl seedling machine transplanting early rice were significantly better than those of carpet seedlings. The sowing date of bowl seedlings could be 10-15 days earlier than that of carpet seedlings, and the optimal sowing date is March 1st. The maturity date of early rice bowl seedlings was 3-6 days earlier than that of carpet seedlings, and 7-10 days earlier than that of early rice direct-seedings. In the production of early rice, bowl seedling transplanting with soil and without planting injury was conducive to seedling survival and tillering occurrence. Compared with carpet seedling machine transplanting, it had the advantage of early tillering for 10 days, the tillering outbreak period was 15-20 days after transplanting. Most of the tillers were effective tillers at low nodes, which were easy to form large panicles. Under the same sowing date, the bowl seedling machine transplanting early rice had the advantage of increasing yield than carpet seedling machine transplanting. The yield increase was mainly due to the more panicles, larger panicles and more grains caused by the early tillering of bowl seedlings.

Key words: early rice, sowing date, bowl seedling, carpet seedling
