采用 3个不同熟期的水稻品种 ,在不同形式的混合稀植栽培条件下种植 ,阐述了各品种的生育性状 (株高、叶龄、叶龄指数、茎数、生长量 )在各生育时期的高产生育指标及增长规律、产量、产量结构 (每穴穗数、穗粒数、单穴粒重、经济系数、千粒重、饱满率 )及增产比例。
Three different maturity rice cultivars were planted under different forms of mixed and sparse cultivation. The fertility characteristics (plant height, leaf age, leaf index, number of stalks, growth) The yield and yield structure (per spike per spike, spike per spike, single grain weight, economic coefficient, 1000-grain weight, plumpness) and the proportion of yield increase.
