不同播种量对直播-再生稻产量的影响

Effect of Different Seeding Rates on the Yield of Direct Seeding-Ratoon Rice

[目的]研究不同播种量对直播-再生稻产量的影响。[方法]以准两优608和两优527为材料,研究不同播种量对直播-再生稻产量的影响。[结果]在"直播-再生"的栽培方式下,准两优608和两优527的适宜播种量为30 kg/hm2。[结论]该研究可为南昌市的直播-再生稻的高产栽培技术提供科学依据。

[Objective] The research aimed to study the influence of different seeding rates on the yield of direct seeding- ratoon rice. [Method]Using Zhunliangyou 608 and Liangyou 527 as the materials,this paper studied the effect of different seeding rates on the yield of direct seeding- ratoon rice. [Result]Under the＂direct seeding- ratoon＂cultivation method,the appropriate seeding rate of Zhunliangyou 608 and Liangyou 527 was 30 kg / hm^2. [Conclusion] The research could provide scientific basis for high- yield cultivation technology of direct seeding- ratoon rice.
