一、适时收割 优质稻的收获时期对产量和米质的影响较大。收获过早,籽粒不饱满,青粒米多,脱粒困难,产量较低,而且碾米时米粒易碎,整精米率和精米率降低;收获过迟,易掉粒,枝梗易折断,米糠层加厚,加工损失较大,裂纹米增多,同样会影响优质稻的产量和品质。优质稻何时收获最好呢?主要是根据谷粒是否已成熟,干物质重是否已达最大值来定。 优质稻的成熟过程同样可分为乳熟期,蜡熟期、完熟期和枯熟期4个时期。乳熟期又称灌浆期,以米粒内
First, timely harvest of high-quality rice harvest on the yield and quality of the larger rice. Premature harvest, incomplete grain, more grains of rice, difficulty in threshing, low yield, and the rice grains are fragile when milled, the rate of milled rice and milled rice is reduced; the harvest is too late, Thicker layers, larger processing losses and increased cracked rice will also affect the yield and quality of high quality rice. When is the best harvest of high-quality rice is mainly based on whether the grain has matured, whether the maximum dry matter weight to be set. High-quality rice maturation process can also be divided into milky maturity, wax maturity, maturity and dry period of 4 periods. Milky maturity, also known as filling period, with rice inside
