福州市郊区小麦田杂草的危害比较严重。近年来小麦推广宽畦撒播,锄草困难,用手工拔草,工效很低,往往除草不及时,影响小麦产量的提高。杂草不仅直接与小麦争夺肥、水、光,而且是害虫寄生和越多的场所。因此,开展麦田除草的研究是贫下中农迫切的需要。一九七二年冬我们与福州市郊金星大队科技组一起,开展麦田化学除草试验,通过小区和大田试验,证明“扑草净”和“西玛津”防治麦田杂草效果良好。现将试验结果整理如下:一、扑草净:是一种内吸传导型除草剂。它有良好脂溶性,能透过植物表皮,被根系吸收再运输到地上部分,抑制植物光合作用;又可通过茎、叶吸收进入体内,有一定触杀作 Fuzhou suburbs of wheat weeds more serious harm. In recent years, popularization of broad wheat spread sowing wheat, weeding difficulties, hand weeding, ergonomics is very low, often weeding is not timely, affecting wheat yield increase. Weeds not only fight directly with wheat fat, water, light, but also the pest parasites and more places. Therefore, carrying out research on wheat weeding is an urgent need of the poor and middle peasants. In the winter of 1972, we carried out the weed experiment on wheat field with the Venus Brigade Science and Technology Group in the suburbs of Fuzhou, and proved that “weed net” and “Simazine” had a good effect on weeds in wheat field through plot and field experiments . The test results are now organized as follows: First, prometryn: is a kind of absorption-type herbicides. It has good fat-soluble, through the plant epidermis, absorbed by the roots and then transported to the aerial part of the inhibition of plant photosynthesis; but also through the stems and leaves absorbed into the body, there is a certain touch to kill
