稻米品质的优劣主要决定于品种的遗传特性,如胶稠度,直链淀粉含量等性状一般比较稳定,但一些加工品质及外观品质等则受环境条件(主要是气温)的影响较大。本文通过比较不同栽培季节的汕优63稻米理化性状的差异,分析气温对品质的影响因素及相关程序,稳定汕优63在我地的最佳品质的种植栽培季节. 一、材料与方法将汕优63组合在我地分别于3月中旬、5月中旬、6月中旬播种,即作早稻、中稻和晚稻种植、齐穗期分别在7
The quality of rice mainly depends on the genetic characteristics of varieties, such as gel consistency, amylose content and other traits are generally stable, but some processing quality and appearance quality is greatly affected by environmental conditions (mainly temperature). This paper compares the different physical and chemical properties of Shanyou 63 rice in different cultivation seasons, analyzes the influencing factors of temperature on quality and related procedures, and stabilizes the planting season of Shanyou 63 in the best quality in our country.Materials and MethodsSanshan You 63 combinations were sown in mid-March, mid-May and mid-June respectively, that is, early rice, middle-aged rice and late rice were planted in full heading stages at 7
