一、喷施微肥的效果制种后期进行根外喷施硼砂、磷酸二氢钾混和液,有利于提高结实率和千粒重,有利于提高制种单产。据试验,硼砂、磷酸二氢钾混喷的比单喷磷酸二氢钾提高结实率2.2%,千粒重增加0.07克,亩实产增加20斤;比单喷硼砂的提高结实率1.7%,千粒重增加0.32%,亩实产增加16.5斤;比不喷的(喷水)提高结实率3.1%,千粒重增加0.58克,亩实产增加30斤,增产13.04%。
First, the effect of spraying fertilizers Late seed spraying with borax, potassium dihydrogen phosphate mixed solution is conducive to improving the seed setting rate and 1000-grain weight, is conducive to improving seed production. According to the experiment, borax and potassium dihydrogen phosphate mixed spray increased the seed setting rate by 2.2% and the thousand-grain weight by 0.07g, and the yield per mu increased by 20kg. Compared with the single-spray borax, the seed setting increased by 1.7% 0.32% increase in real production of 16.5 kg; non-sprayed (water spray) to improve seed set rate of 3.1%, 1000 grain weight increased 0.58 grams, 30 acres increase in real production, an increase of 13.04%.
