施肥和除草是水稻栽培中的两项重要技术措施,而镇海炼化股份有限公司生产的除草包膜尿素(简称除草尿素)就兼有这两方面的功能。近几年我们多点、多次对其进行了除草效果、肥效、增产作用、安全性及其应用技术的试验研究。结果表明,除草尿素由于含有适量多元广谱型除草剂,能有效地防治水田中单子叶或双子叶杂草,对稗草防治效果尤佳,是水田一次性广谱除草药肥。根据小区对比试验,移栽早稻田亩施除草尿素10公斤作第一次追肥,杂草总体株防率93.94%,鲜重防效率96.84%,比亩施普通尿素10公斤+15%乐草隆40克
Fertilization and weeding are two important technical measures in rice cultivation. Herbicidal coated urea produced by Zhenhai Refining & Chemical Co., Ltd. (hereinafter referred to as herbicidal urea) has both of these functions. In recent years, we have more and more carried out many of its weeding effect, fertilizer efficiency, production, safety and application of experimental research. The results showed that herbicide urea could effectively prevent and control monocotyledonous or dicotyledonous weeds in paddy field because of its proper amount of broad-spectrum herbicides, which was especially effective in controlling barnyardgrass and was a one-time broad-spectrum herbicide. According to the plot comparative test, the transplanting of rice in the morning paddy field Mushi Shi urea 10 kg for the first top-dressing, weeds overall plant prevention rate of 93.94%, fresh weight control efficiency of 96.84%, 10 kg than the ordinary urea urea + 15% G
