近年,美国在论证新的耐除草剂大豆品种的性能,以及比较耐除草剂品种与传统品种的产量方面下了很大功夫。 选择作物品种和更换作物品种是件复杂的至关重要的事,因为改换品种可能会影响到农场的利润。试验证明,耐磺酰脲除草剂的大豆(称为STS大豆)的产量比传统品种的产量高。由美国Asgrow种子公司生产的STS大豆种子以及相应的除草计划,统称为STS体系。几年的对照试验表明,STS体系有产量高;封垅快;对作物无压力、可使作物发挥全部遗传措力,长得更快、更健康;除草效果好;使用灵活等优点: In recent years, the United States has made great efforts to demonstrate the performance of new herbicide tolerant soybean varieties and compare the yield of herbicide tolerant and traditional varieties. Choosing crop varieties and changing crop varieties is a complex and crucial matter, as changing varieties may affect farm profits. Tests have shown that the production of sulfonamide-tolerant soybeans, known as STS soybeans, is higher than that of traditional varieties. The STS soybean seeds produced by Asgrow Seed Company of the United States and the corresponding weeding program are collectively referred to as the STS system. Several years of controlled trials have shown that the STS system has the advantages of high yield, fast sealing, no pressure on the crop, allowing the crop to exert all genetic measures to grow faster and healthier, better weeding effect,
