| 摘 要： | 以五优稻1号为供试品种,设A(两段育苗)、B(超早育苗)、C(常规育苗)等三个处理,研究了三种不同育苗方法对水稻生育及产量的影响.结果表明,处理间的秧苗素质差异显著;处理间的生育期差异非常大,但成熟期差异并不很大;处理间茎蘖动态、叶面积动态、干物质动态等均有极为明显的差异;产量呈A(12547.6kg/hm2)＞B(10679.3kg/hm2)＞C(7846.1kg/hm2).可见,处理A(两段育苗)和处理B(一段超早育苗)是寒地水稻超高产栽培的重要技术途径.

| Abstract: | Three treatments of A(two sections growing seedlings), B(super early growing seedlings), C(conventional growing seedlings) were designed to study the effect of different growing seedlings methods on the growth and yield of rice. The results showed that: The difference of the seedling quality of different treatments was significant; the difference of growth period of different treatments was obvious, but that of maturation period was not obvious; the difference of the dynamic change of tiller growing, leaf area index , dry matter weight under different treatments was extremely significant, the yield showed the tendency of A>B>C. Treatment A and treatment B were important technology of Super High-yield cultivation of rice in cold zone. |
