在甘蔗栽培中,冬植蔗的产量和糖份虽然比春植蔗的高,但由于冬季气温低、雨水少,对甘蔗萌芽生长不利,冬植蔗到2月下旬(桂南)至4月(桂北)才萌芽。由于蔗种长期埋在地下,凤梨病严重,萌芽率一般达30-40%,少的则只有10%左右,所以造成严重缺株断垄,亩有效茎少,产量低,也影响了蔗农种冬植蔗的积极性。因此,如何提高冬植蔗的萌芽率,增加亩有效茎数,以提高亩产蔗量已成为当前急待研究解决的重要课题。现将我所于1981年末及1982年初进
In sugar cane cultivation, although the yield and sugar content of winter sugarcane are higher than that of spring sugarcane, due to low winter temperatures and few rainfall, winter sugarcane is unfavorable to germination and growth of sugarcane, and winter sugarcane will be in late February (Guinan) till April (North Guangxi) before germination. As the cane species buried in the ground for a long time, pineapple disease is serious, the germination rate is generally 30-40%, while the less is only about 10%, resulting in serious lack of broken line ridge, mulberry, less effective and low yield, but also affected sugarcane farmers Winter sugarcane enthusiasm. Therefore, how to improve the rate of germination of winter cane and increase the number of effective stalks to increase the amount of cane per acre has become an urgent issue to be solved urgently. Now I entered in late 1981 and early 1982
