花生是我场旱地种植的主要经济作物,播种面积常年在4000亩左右。长期以来,杂草的危害一直影响我场花生的高产稳产,杂草的种群主要是马唐,其次是香附子。1987年开始,我们进行了地乐胺防除花生地杂草的试验,1988年重复试验,同时还进行了大面积的示范和推广,均取得了满意的效果。现将试验和示范情况整理总结如下,供参考。 Peanut is the main cash crop planted in dry field in our country. The sown area is about 4,000 acres all the year round. For a long time, the harm of weeds has always affected the high and stable yield of peanuts in our field. The population of weeds is mainly crabgrass, followed by the monkshoods. Beginning in 1987, we carried out the test of deniline against peanut weeds. We repeated the tests in 1988 and carried out large-scale demonstration and popularization with satisfactory results. The test and demonstration are summarized below, for reference.
