【摘要】 以生产上推广的超级稻准两优527为材料,研究了不同栽植方式对水稻生长发育的影响。试验表明:水稻移栽随着苗龄的推迟,其生育期将相对延长,免耕直播比移栽的生育期相对缩短;移栽的成穗率均高于免耕直播;移栽均比免耕直播增产。更多还原

【Abstract】 Zhunliangyou 527(a super-rice variety) was tested under different planting patterns to study the effect on its agronomic character and yield. The results showed that the growth period was delayed with increase of rice seedling age, the growth period with the zero tillage and direct sowing pattern was shorter than that with the transplanting pattern and the yield with the transplanting pattern was higher than that with the zero tillage and direct sowing pattern because of its higher effective spike rate.更多还原
