摘要
基于穴盘旱育秧技术研究不同播期和播量对水稻产量的影响,结果表明,播期和穴播量对穴盘旱育秧水稻分蘖动态、生育进程、每公顷穗数、穗实粒数及稻谷产量都有较明显的影响,以播期5月20日播量5粒/穴处理的产量最高,为10285.5kg/hm^2。
The effects of different sowing time and sowing rate on rice production were studied based on the technique of dry raising seedlings in aperture disk.The results showed that sowing time and sowing rate had obvious influence on tillering dynamics,growth process,spike number per hectare,grain number per spike and yield of rice.Comprehensive analysis showed that the highest yield was 10285.5 kg/hm2 under the conditions of sowing on May 20 with 5 grains per hole.
