对单季晚粳秀水134进行直播栽培方式下播种期与播种量的双因素试验,结果表明：在每667 m2600 kg产量水平下,适宜的播种期为5月27日至6月3日、播种量为2.5～3.0 kg,适期早播稀播,有利于培育壮苗,提高产量。

Double factors tests on sowing date and seeding rate of single cropping of late japonica rice variety Xiushui134 by using direct-seeding method were conducted.The results showed that,the optimum sowing time was from May 27 to June 3 and rational seeding rates was 2.5-3.0 kg,when the target yield per 667m2 was 600kg,early sowing in good time with low density would be beneficial for nursing vigorous seedlings and thus improving the grain yield.
