用50%的尿浸玉米种6～8小时,能加速种子内部酶的活动,并具有肥育种子的作用,对提前出苗和前期壮苗,提高产量均有一定的效果。据山东招远、掖县、莱阳等县试验和大田考察,尿浸种的一般提早出苗1～2天,三叶期前表现叶绿、苗壮,一般增产2～10%。用尿水浸种,应掌握尿与水的比例不得超过50%,浸种时间长短,应按品种不同而定,马齿型的适当短些,硬粒型的可适当长些。浸过的种子要及时下种,原则是:“早”浸不过
Maize with 50% urine maize 6 to 8 hours, can speed up the activity of the enzyme inside the seed, and has the role of fattening seeds, early emergence and early seedling, increase production have a certain effect. According to Shandong Zhaoyuan, Ye County, Laiyang and other county trials and field investigations, the general emergence of urine soaking seedling 1-2 days, three-leaf stage before the performance of leaf green, Miao Zhuang, the general increase of 2 to 10%. Soaked with urine, should master the ratio of urine and water shall not exceed 50%, soaking time, should be different varieties, shorter appropriate dent type, hard type may be appropriate longer. Soaked seeds to timely under the species, the principle is: “early” dip too
