谷子化控免间苗栽培技术是根据谷子籽粒太小、顶土力差、单粒种子难以保障顶土出苗,靠群体萌芽顶土才能出苗的特点,研制出的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制剂处理谷种的种苗逐渐枯萎死亡,而留下正常种苗,这样不用间苗或少间苗,即可实现大田谷子栽培密度要求。一、谷子化控免间苗栽培技术的优点
Miao-controlled millet seedless millet cultivation technology is based on millet grains is too small, poor top soil, single seed is difficult to protect the top soil emergence, by the germination of top soil to germination characteristics, developed a can guarantee the normal germination of millet seedlings Play the role of top soil group, but also in the emergence of MND preparation after death. The seeds treated with this preparation are mixed with normal cereals according to a certain proportion, and after emergence, seedlings of MND preparation treated with grain seed gradually wither and die, and leave normal seedlings, so that no seedlings or few seedlings are needed, To achieve millet millet cultivation density requirements. First, the Millet-free seedling cultivation technology advantages
