夏播大豆施用ＡＢＴ生根粉效果显著随着春小麦生产的发展，我县夏播大豆面积不断扩大，每年种植３万亩左右，但由于夏播大豆生育期短，分枝少，单株生产力低，产量也一直较低。为了提高大豆的产量，力争投资少，见效快，我们于１９９３年开始引进了ａＢＴ生根粉，在大城子...
Summer broadcast Soybean application of ABT rooting powder significant effect With the development of spring wheat production, my county summer sowing soybean area continues to grow, about 30,000 acres planted each year, but due to summer sowing soybean growth period is short, less branches, low per plant productivity, Production has also been low. In order to improve soybean production, and strive to invest less, quick, we started in 1993 introduced aBT rooting powder, Ayutthaya ...
