晋东南地区1979年小麦播种时底墒不足,一冬无雪,1980年早春又发生了严重冻害,使小麦大幅度减产。从偶然的埋土现象中,我们发现小麦干旱受冻的要害是其分蘖节,1981年以来,长治县北呈乡农科站王书成和长治县南董村胡师则,连续3年进行了试验、示范,摸索出了一条旱地小麦抗旱防冻增产的好办法——小沟垅种植法。 In southeast region of Shandong in 1979 sowing at the end of lack of moisture, a winter without snow, in early 1980 there was a serious freeze injury, so that a substantial wheat yield. From accidental burying, we found that the key to the freezing of wheat drought is its tillering node. Since 1981, Wang Shicheng of Agricultural Science Station of Beicheng Township in Changzhi County and Hu Shizhi of Nan Dong Village of Changzhi County have been tested for three consecutive years Demonstration and worked out a good way to drought drought and drought-resistant wheat yield - small ditch planting method.
