播前整地好坏,对作物出苗影响很大。有关资料说明,棉苗出土多少与整地的坷垃多少有直接关系,每平方米内有直径4—5厘米的坷垃18—20块,出苗27—39株,每平方米有坷垃50—70块,出苗只有1—5株,坷垃增加1.5—2.5倍,出苗减少4—30倍。麦田整地细平的,平均每米出苗73.3株,无断垄现象,整地差的平均每米出苗64株,1米以上断垄5.5%。可见整好地是种好的基础。下面谈谈如何保证机耕质量问题。
Before planting sowing is good or bad, a great impact on crop emergence. Relevant information shows that the number of unearthed cotton seedlings and the preparation of the number of grasshoppers are directly related to the per square meter diameter of 4-5 cm diameter Kee rubbings 18-20, emergence of 27-39 strains per square meter of Ke rub garbage 50-70, emergence Only 1-5 strains, Ke rub increased 1.5-2.5 times, 4-30 times reduce emergence. Cropping of wheat field is smooth, with an average of 73.3 plants per meter. There is no broken ridge phenomenon. The average yield per plant is 64 per meter, and the width of more than 1 meter is 5.5%. We can see that the whole is a good foundation. Here to talk about how to ensure the quality of the plow.
