以早籼杂交稻金优433、T优535和中熟晚籼杂交稻金优207为材料,进行直播栽培和育苗移植栽培比较试验。结果表明,金优433的产量,比对照高1.4%,T优535的产量比对照低5.9%。同时,分析了直播栽培省工省力、产量较高的原因,得出选用分蘖力较强、株高较矮、穗较短和结实率高的优质早籼杂交稻品种做晚稻直播栽培适宜在丘陵地区推广的结论。
A comparative experiment on direct seeding cultivation and seedling transplanting culture was conducted using the indica hybrid rice Jinyou 433, T You 535 and the mid-maturing late indica hybrid rice Jinyou 207 as materials. The results showed that the yield of Jinyou 433 was 1.4% higher than that of the control and that of Tanyou 535 was 5.9% lower than that of the control. At the same time, the reason of saving labor and high yield of direct-seeding cultivation was analyzed. It was concluded that the direct seeding cultivation of late-season rice with high tillering ability, short height, short spike and high seed setting, Regional promotion of the conclusion.
