谷子生产中的“一低三难”(产量低、保苗难、间苗难、锄苗难)问题,特别是间苗的艰辛劳作,极大地影响了谷子种植规模的扩大和谷子产业的发展壮大。为解决这一问题,山西省农业科学院谷子研究所研制出一种既能保证谷子正常发芽出苗发挥群体顶土作用,又能在出苗后自行死亡的MND制剂。把用这种制剂处理过的谷种和正常谷种按一定比例混匀播种,出苗后,MND制剂处理过的谷种2叶期开始逐渐枯萎死亡,而未处理过的种苗
Millet production in the “low three” (low yield, seedling difficult, thinning seedling difficult, hoe seedling difficult), especially the Miao Miao hard work, greatly affected the expansion of millet plantations and millet industry to grow and develop . In order to solve this problem, the Institute of Millet Research, Shanxi Academy of Agricultural Sciences, has developed a MND preparation which can ensure that the normal germination and emergence of millet can play the role of the top soil of the population and can die after emergence. The seedlings treated with this preparation were mixed and planted according to a certain proportion. After emergence, the 2-leaf stage of the MND preparation treated grain began to wither and die, while the untreated seedlings
