杂草与花生争肥、水和光,对花生的生长和产量影响很大,一般草害造成减产20～30%.在广西亚热带半干旱岩溶区为地多人少地区,杂草影响花生产量尤为突出.我们在典型半干旱岩溶农业生态区——来宾县小平阳实施“治旱工程”项目同时,对50%乙草胺乳油防除花生田杂草的效果和使用的最佳浓度进行试验,现将结果总结供各地推广使用时作参考.一、处理内容和方法1.常规花生地(露地):乙草胺设亩施50、75、100和125克四个浓度,空白对照,共5个处理,重复两次,每小区约33m~2.
Weeds and peanuts fight fat, water and light, great impact on the growth and yield of peanut, the general grass damage caused by 20 to 30% .In Guangxi subtropical semi-arid karst area for more people and less areas, weeds particularly affect peanut production Highlighting the effects of 50% acetochlor EC on weeds in peanut field and the optimum concentration for its use in a typical semi-arid karst agro-ecological zone - Xiaobianyang, Laibin County The results for reference to promote the use of all around for reference 1. First, the treatment methods and contents 1. Conventional peanut (open field): acetochlor set Mushi 50,75,100 and 125 grams of four concentrations, a blank control, a total of 5 Processing, repeated twice, each about 33m ~ 2.
