近年来,随着农村生产结构的调整,新沂县蚕桑生产发展很快。据县多管局统计,1988年全县新扩种桑圃0.17万亩,可栽植大田万余亩。桑苗圃田投肥多,湿度大,杂多草且难拔除,严重影响桑苗素质。为解决桑苗圃田草害问题,我们在1987年和1988年进行防治试验,将结果整理如下。 试验设在唐店乡农科站桑苗圃田,处理有50％杀草丹乳油100毫升/亩;60％丁草胺乳油100毫升/亩;15％稳杀得乳油100毫升/亩12.5％盖草能100毫升/亩;10％禾草克乳油100毫升/亩;以喷清水为对照。采用随机区组排列,重复3次,小区面积为28平方米,试验品种
In recent years, with the adjustment of rural production structure, silkworm mulberry production in Xinyi County has developed rapidly. According to the statistics of the County Multi-Office, in 1988, the county’s newly expanded planting area of 0.17 million mu of mulberry trees could be planted with more than 10,000 mu of fields.

In order to solve the problem of field nuisance, we conducted prevention and cure tests in 1987 and 1988, and the results are summarized as follows. The experiment is located in Tangshen Township Agricultural Station Sang nursery Tian, dealing with 50% kill grass Dan Dan EC 100 ml / mu; 60% Butachlor EC 100 ml / mu; 15% stable EC 100 ml / mu 12.5% Grass to 100 ml / mu; 10% Wo Ke Ke EC 100 ml / mu; to spray water as a control. Using random block arrangement, repeated 3 times, the plot area of 28 square meters, test varieties
