以豫谷18为试验材料,通过研究最佳化控药剂配比、处理剂量和药剂处理谷种与正常谷种的最佳混播比例,以实现谷子化控间苗的目的。试验结果表明,豫谷18经DO(300mg/L)和KO(40mg/L)药剂复配浸种12h,再以正常谷种占总播量的30%~40%的比例进行播种,既能保证正常发芽出苗、发挥群体顶土出苗的作用,又能实现化控间苗的目的。
Taking Yugu 18 as the experimental material, the optimal mixing ratio of treatment chemicals, the treatment dose and the optimum mixing ratio of the seed treatment with the normal grain seed were studied to achieve the goal of millet seedling control. The results showed that Yugu 18 seeds were soaked in DO (300mg / L) and KO (40mg / L) for 12h, and the seeds were planted in the proportion of 30% ~ 40% Sprouting emergence, the role of top seedlings play a role, but also to achieve the purpose of the control room between seedlings.
