历年来,望谟县早稻烂秧严重,晚稻产量不高,究其原因尽管是多方面的,但主要受热量条件的影响。因此,分析望谟县的热量条件,对于合理充分地利用农业气象资源、避免和减少损失、提高望谟水稻单产,具有重要意义。一、从热量条件确定早稻播种期望谟可种双季稻面积3万亩,常年种双季稻1.5万亩左右。早稻以常规稻为主,杂稻次之,也有少量糯稻栽培。酶能加速生物体内物质的变化,其强度与温度有关通常认为,10～12℃是谷粒发芽的最低温度,32℃是最适温度,40℃是最高
Over the years, Wangmu County early rice rotten seedling serious, late rice yield is not high, although the reasons are many, but mainly by the impact of heat conditions. Therefore, it is of great significance to analyze the caloric conditions of Wangmian County in order to rationally make full use of agricultural meteorological resources, avoid and reduce losses and improve rice yield in Wangmo County. First, from the heat conditions to determine the planting of early rice Wang Mo double crop rice area of 30000 acres, perennial double crop of about 15000 acres. Early rice is dominated by conventional rice, followed by hybrid rice, but also a small amount of glutinous rice cultivation. Enzymes can speed up changes in the biological material, the intensity and temperature is generally believed that 10 ~ 12 ℃ is the minimum temperature of grain germination, 32 ℃ is the optimum temperature, 40 ℃ is the highest
