小麦播种前对种子进行处理,可以促进早出苗、出壮苗。常见的种子处理方法如下:一、浸种1.氯化钙浸种。播种前将麦种放入0.25%的氯化钙溶液中浸泡24小时,然后捞出,晾干后播种。可以促进出苗,增强植株抗干热风的能力。2.磷酸二氢钾浸种。将麦种浸泡在0.2%~0.3%的磷酸二氢钾溶液中,12小时后捞出,晾干后播种。磷酸二氢钾浸种具有壮苗、促进分蘖、提高产量的功效。
Wheat seeds before sowing treatment, can promote early emergence, strong seedlings. Common seed treatment methods are as follows: First, soaking 1. Calcium chloride soaking. Before sowing the wheat into 0.25% calcium chloride solution soak for 24 hours, then remove, dry and sow. Can promote emergence, enhance the ability of plants to resist dry hot air. 2. potassium dihydrogen phosphate soaked. Soak the wheat seeds in 0.2% ~ 0.3% potassium dihydrogen phosphate solution, remove after 12 hours, dry and sow. Potassium dihydrogen phosphate soaking seedlings with seedlings to promote tillering and improve the yield of the effect.
