福海县地处新疆,阿勒泰山以南地带,属于高寒春小麦区。麦田杂草种类较多,覆盖度大,严重影响了春麦的生长及产量。据八二年调查:麦田杂草有14科39种,其中阔叶类的灰藜,苍耳、田旋花、苦豆子,野豌豆等占75％,一般地块每平方米都在250—450株范围之内。通过取样测产得知:当年损失小麦产量为220万斤。 76年在我县小面积试验2·4—D丁酯除草剂成功后,迅速转入大田推广。近年来,除草面积已达万亩以上,收到了较好的效果。
Fuhai County is located in Xinjiang, south of Mount Altay, belonging to alpine spring wheat area. There were more weeds in the wheat field and more coverage, which seriously affected the growth and yield of spring wheat. According to the survey in 1982, there were 39 families and 14 families of weeds in wheat fields, of which 75% of broad-leaved quinoa, cocklebur, field convolvulus, bitter pea and wild pea accounted for 75% 450 strains within the scope. Measured by sampling that: the loss of wheat production was 2.2 million pounds. 76 years in my county small area test 2.4-D butyl herbicide success, quickly transferred to Daejeon promotion. In recent years, weeding area has reached more than mu, received good results.
