经测定,蔗地深耕深松对甘蔗前期吸收N、P、K有促进作用,且旺盛生长期甘蔗+3叶的叶长,叶宽超过对照,叶面积系数比对照增加10%左右;甘蔗产量比对照增加2.68—16.80%;甘蔗蔗糖分比对照高0.32—2.27%。因此认为:蔗地深耕深松有利于旱地甘蔗前期早生快发,促进后期糖分积累,使甘蔗增产增糖。
It was determined that deep plowing and deep plowing in sugarcane field could promote the absorption of N, P and K in early stage of sugarcane, and the leaf length and leaf width of sugarcane +3 leaf in the vigorous growing stage were more than those in the control, and the leaf area coefficient increased about 10% Control increased 2.68-16.80%; sugar cane sugar content higher than the control 0.32-2.27%. Therefore, it is concluded that deep plowing and deep plowing in sugarcane fields are good for quick early stem growth of sugarcane in dry land and promoting late accumulation of sugars, increasing sugarcane production and increasing sugar content.
