以20个杂交中稻组合为材料,在冬水田高密低肥、中密中肥和低密高肥3类栽培模式下,研究了产量及库源性状的变异。结果表明,产量在3个栽培模式间、20个杂交组合间及栽培模式与杂交组合间的交互作用均达极显著水平,20个杂交组合在3种栽培模式的平均产量表现为高密低肥>中密中肥>低密高肥,分别筛选出了适宜3种栽培模式和同时适宜3种栽培模式的杂交组合。
With 20 hybrid mid-rice combinations as materials, the variations of yield and sink-source traits were studied in three types of high-density, low-fertilization, medium-density and medium- The results showed that the interaction between the three cultivation modes, the twenty hybrid combinations and the cultivation patterns and the hybrid combinations were all reached extremely significant level. The average yield of the 20 hybrid combinations in the three cultivation patterns showed high density and low fertilizer> Zhongmi Zhongfei> low density and high fat were selected, respectively, suitable for three kinds of cultivation patterns and suitable for three kinds of cultivation patterns of hybrid combinations.
