通过分期播种和分期栽插以测定水稻籽粒灌浆特性和稻米品质的关系。结果是:一般情况下,谷粒灌浆前、中期的灌浆速度与总精米率、整精米率、垩白大小、碱解度,胶稠度均呈反相关趋势而与透明度呈正相关趋势;而灌浆后期的情况则与前、中期表现有相反趋势。 The relationship between rice grain filling characteristics and rice quality was determined by sowing and staging in stages. The results were as follows: Under normal circumstances, grain filling rate before and during grain filling was inversely correlated with total milled rice rate, milled rice rate, chalkiness, alkalinity and gel consistency, but positively correlated with transparency; The situation is contrary to the previous and mid-term trends.
