“秧好半年禾”。杂交水稻在较好的育秧条件下,在秧田期带分蘖的秧苗素质好些,移栽后比无蘖秧增产效果显著。但对秧苗素质与产量形成的内在联系,过去知道的不多。在1977年早造和晚造中,我们对矮优3号和常优7号作了试验,早造分无蘖秧、二叉秧(带一个分蘖)和三叉秧(带2个分蘖)3种处理,插植规格为8×4寸;晚造分无蘖秧、二叉秧、三叉秧和四叉秧4种处理,插植规格为9×3寸。早、晚造均为单株插植,试验共分3次重复。在整个生育过程中
“Ye Hao six months Wo.” Hybrid rice under good seedling raising conditions, tillering seedling stage seedling quality better, after transplanting than tillering seedling yield significantly. However, the inherent relationship between the quality of seedlings and the formation of yield did not know much in the past. In early and late 1977, we tested Shorty-3 and Changyou-7 with tillers, tillers (with one tiller) and trigeminal tillers (with two tillers) 3 Seed treatment, planting specifications for the 8 × 4 inch; late points without tillering seedling, two-yang seedlings, trilogy and quadrupedal seedlings 4 treatment, planting specifications for the 9 × 3 inch. Early and late are single plant implants, the test is divided into 3 times repeated. Throughout the birth process
