生产实验证明,用过磷酸钙、硼酸混合液拌小麦种子,有显著的抗旱增产效果。据青海、甘肃、黑龙江等省一些干旱地区试验示范、一般可增产小麦百分之十至四十三。具体做法是:一、配制溶液,选质量较好的过磷酸钙六斤,加水一百斤,充分搅动,促其充分溶解,然后静置十五分钟左右,沉淀后,将澄清液取出,即为百分之六的过磷酸钙溶液。然后再加入百分之零点一的硼酸,即向溶液中加硼酸一两,充分搅拌就制成过磷酸钙和珊酸混合液。如无硼酸,可用硼砂代替,但用量
Production experiments show that with superphosphate, boric acid mixed wheat seed mix, a significant increase in drought resistance and yield. According to experimental demonstrations in some arid regions of Qinghai, Gansu and Heilongjiang provinces, generally wheat yield can be increased by 10 to 43 percent. Specific approach is: First, the preparation of the solution, select the better quality superphosphate six pounds, add water, one hundred jins, stir, promote its full dissolution, and then set aside for about fifteen minutes, after precipitation, the clear liquid removed, that is Six percent of superphosphate solution. Then add 0.1 percent of boric acid, boric acid to the solution one or two, fully mixed to make a mixture of superphosphate and sanshin. If no boric acid, borax can be used instead, but the amount
