生产优质稻米,仅选用优良品种是不够的,栽培措施在一定程度上也左右着稻米品质。 (一)播种期 同一品种提早播种,可增加稻米中淀粉含量,降低蛋白质含量。 (二)本田密度 基本苗过多会导致糙米率、精米率和整精米率下降,垩白粒率和整精米率增加,米粒透明度差,直链淀粉含量与胶稠度升高,蛋白质含量下降。采用水稻旱育 Producing quality rice is not enough to use only fine varieties, and cultivation practices to a certain extent also affect the quality of rice. (A) sowing the same species of early sowing, can increase the starch content in rice, reduce protein content. (B) too much Honda density seedlings will result in brown rice rate, milled rice rate and milled rice rate decreased, chalky grain rate and milled rice rate increased, rice transparency is poor, amylose content and gel consistency, protein content decreased.
