以东农423(V7)为供试品种,在水稻三超栽培条件下,设A、B、C等密度相同而行株距不同的3个处理,研究了宽行处理A(42 cm×14.3 cm)和B(36 cm×16.7 cm)与窄行处理C(30 cm×20 cm)对水稻生育及产量的影响。结果表明:处理间的茎蘖动态、叶面积指数、叶绿素含量、干物质积累、产量及其构成因素等均呈A>B>C趋势,说明宽行栽培更有利于水稻的超高产。
Taking Dongnong 423 (V7) as the tested variety, three treatments (A, B and C) with the same density and different row spacing were conducted under the rice super-cultivation conditions. The effects of broad-width treatment A (42 cm × 14.3 cm ) And B (36 cm × 16.7 cm) and narrow row treatments C (30 cm × 20 cm) on the growth and yield of rice. The results showed that the trends of stem tiller, leaf area index, chlorophyll content, dry matter accumulation, yield and its components all showed A> B> C between treatments, which indicated that broad-leaved cultivation was more favorable for super high yielding rice.
