摘要
试验选用黑龙江省生产实践中广泛种植的8个优良品种,并在不同稀植处理下施三叶肥、花期肥,通过田间试验对稀植栽培下春小麦氮素转移、蛋白质含量变化、产量及构成因素进行研究。结果表明,3种处理下旗叶和籽粒的氮素含量变化呈交叉式,变化规律基本一致,龙麦29和克丰6籽粒蛋白质含量表现为显著增加,其他品种蛋白质含量差异不大。稀植与常规处理下各品种产量变化表现不一致。
Eight spring wheat cuhivars planted extensively in Heilongjiang Province were selected for the experiment, then applied fertilizer in three leaves stage and head sprouting stage under different seeding density. Nitroge＇n transfer, protein content, yield and yield components under low seeding density cultivation were studied through field experiment. The results showed that nitrogen content of flag leaf and grain changed in the form of intersect, the tendency was almost the same, grain protein content of Longmai29 and Kefeng6 inereased significantly, but the others＇ changed a few. Different cultivars yield varied differently between low seeding density treatment and conventional treatment.
