(一)甘蔗收获后,利用残留在地下部分的“蔗头”,促使萌发抽苗,如新植蔗一样加以培育,这便是宿根栽培。我们南方各省及冬季比较温暖的蔗区,宿根栽培非常普遍。全国宿根栽培的面积,约占甘蔗栽培总面积的一半以上。本省目前仅温州专区的滨海蔗园有宿根栽培,温州的沿江华山区以及金华专区,一向没有宿根栽培的习惯。宿根蔗的单位面积产量目前往往以第一年为最高,以后有降低趋势,故宿根蔗一般仅种植二年,第三年起即多半改种其他作物。甘蔗宿根栽培的好处很多,增产的潜力也很大:第一:可以节约种苗。根据本省新植蔗的密植水平,一股每亩的用种量达到1,500斤左右,如以
(A) sugar cane harvest, the use of residues in the underground part of the “sugar head” to promote seedling germination, such as planting new cane to be cultivated, this is the perennial cultivation. Our southern provinces and the warmer cellars in winter, perennial cultivation is very common. Perennial cultivation area, accounting for about half of the total area of sugar cane cultivation. At present, there are only perennial cultivation in Binhai Cane Garden in Wenzhou area, Huashan District along Wenzhou and Jinhua area in Wenzhou. There is no habit of perennial cultivation. The yield per hectare of cane is usually the highest in the first year, and then tends to decrease in the future. Therefore, it is generally planted only for two years. In the third year, most crops will be changed to other crops. There are many benefits of sugarcane pest cultivation, the potential for yield increase is also large: First: you can save seedlings. According to the close planting level of new sugarcane in the province, an acre of about 1,500 kilograms per mu is used,
