前言 目前我省大豆单产较低,其中杂草危害是影响大豆增产的重要因素之一。近年来联产承包责任制和各项农村政策的推行,农村经济发生很大变化,因此大豆田化学除草发展很快。但目前药价偏高,造成使用成本偏高,是除草剂应用中存在的一个问题。我们在使用方法上,采用垅作田间小区苗带施药,减少三分之一用药量。三年试验结果证明,这种施药方法确是一种降低成本及扩大推广面积的有效途径。 Preface At present, the yield of soybean in our province is relatively low, among which weed harm is one of the important factors affecting the soybean yield. In recent years, with the implementation of the household contract responsibility system and various rural policies, great changes have taken place in the rural economy. As a result, chemical weeding in soybean fields has developed rapidly. However, the current high drug prices, resulting in high cost, is the application of herbicides in a problem. We use the method, the use of 垅 for field nursery stocking, reducing the dose of one third. Three years of test results show that this method of application is indeed an effective way to reduce costs and expand the promotion of the area.
