我师位于天山北麓,属大陆性气候,无霜期118——155天,年平均温度4.9℃,年降水134.4—240.3毫米,12月份降雪最多,最大雪深出现在2月份,积雪封冻期长达天140左右.因此,以往农事活动期短,休耕期长.由于生产的迅速发展,耕地面积不断扩大,而整地等基本作业,多集中于春秋雨季进行,因而劳力、机力及灌溉用水均很紧张,往往不能适期播种,影响作物生长发育和产量的提高.为此,我师数年来反复进行了带雪作业和早播作物的生育情况调查.
My teacher is located in the northern foot of Tianshan Mountains, a continental climate, frost-free period of 118--155 days, the annual average temperature of 4.9 ℃, annual rainfall of 134.4-240.3 mm, the most snowfall in December, the maximum snow depth in February, Reaching a day of about 140. Therefore, in the past, due to the short period of agricultural activities and the long fallow period, due to the rapid development of production, the area of arable land continued to expand while the basic operations such as land preparation were mainly concentrated in the spring and autumn rainy season. Therefore, labor, mechanical power and irrigation water Very nervous, often can not be planted properly, affecting crop growth and yield increase.To this end, my teacher repeated over the years with snow operations and early-sowing crops fertility survey.
