整精米率是衡量水稻米质中的一项重要指标,而整精米率与破碎率成反比。宁夏引黄灌区水稻成熟期间空气湿度低,气候干燥,且昼夜温差大,在无风天气,夜间露水较大,易使水稻产生“爆腰”(米粒在稻壳里形成的裂纹),同时,不良的栽培技术也会使水稻米质下降,破碎率升高。如何克服这一劣势,最大限度 Whole rice rate is a measure of rice quality in an important indicator, while the rate of whole rice is inversely proportional to the rate of broken. During the maturing period of rice in Ningxia Yellow River Irrigation Area, the air humidity is low, the climate is dry, and the temperature difference between day and night is large. During the windless weather and large night dew, rice can easily produce “burst waist” (the crack formed in the rice husk) At the same time, poor cultivation techniques will also reduce rice quality and increase the rate of fragmentation. How to overcome this disadvantage, the maximum
