将高吸水性树脂KH841(简称树脂)掺入土壤中可以提高土壤保水能力,减少土壤中水分的蒸发以防止干旱,从而提高种子发芽力和促进幼苗的生长。今年春我们利用蔬菜种子和幼苗在温室中作了一些试验,现将初步结果报告如下: 试验一:蔬菜种子播种出土和幼苗生长情况 树脂是按0.1%,0.3%,0 The incorporation of superabsorbent resin KH841 (referred to as resin) into the soil can improve the soil water retention capacity, reduce the evaporation of moisture in the soil to prevent drought, thereby improving seed germination and seedling growth. This spring we used vegetable seeds and seedlings in the greenhouse to do some experiments, the preliminary results are reported as follows: Experiment 1: Vegetable seed sowing and seedling growth situation Resin is 0.1%, 0.3%, 0
