摘要
分析了小麦矮抗58籽粒灌浆特性及不同栽培措施对其灌浆特性的影响,结果表明:正常条件下矮抗58的灌浆渐增期短,快增期长,缓增期较长;种植密度和氮肥水平对该品种的灌浆特性有明显影响。在该试验条件下,最佳播量是187.5万基本苗/hm2,最佳施纯N量是2512.5kg/hm2。
The effect of diffierent cultivation measures on grain filling rate of wheat variety -aikang 58 was studied. The results showed grain filling prcess of Aikang 58 was the curve of "slow-fast-slow'and the gradual increasing staging was shorter, the rapid increasing stage and slow increasing stage were longer.The planting density and N fertilizer had significate effect on its grain filling under the experiment condition. The optimum planting density was 187.5 thousand seedlings per hectare, and the optimum N fertilizer 16 kg/667m^2.
