甘蔗育苗移栽是节省蔗种,增产增糖的有效措施。但是,由于受灌溉和天气条件的限制,目前主要抢阴雨天栽植,因此影响了该项技术的大面积推广应用。 1987—1988年,我们在旱坡地上进行了甘蔗苗根沾保水剂的移栽试验,取得了良好效果。根据两年4个点的试验结果,苗根沾保水剂移栽同不沾保水剂的对照相比,返青期提前1周左右,成活率提高6—12％。有效茎增加6—20％,蔗茎产量每亩增加216—755公斤,平均增产454公斤,增产率达8—17％,平均为12％,如蔗价每吨按130元计,每亩扣除成本15—20元,亩获纯利润可达13—78元。 Sugarcane seedling transplanting is an effective measure to save sugar cane and increase sugar production. However, due to the restrictions of irrigation and weather conditions, the main grab rainy days planted, thus affecting the large-scale application of the technology. From 1987 to 1988, we carried out transplanting experiments of sugarcane seedling roots with water-holding agent on the dry slopes and achieved good results. According to the test results at 4 points for two years, the rejuvenation period was about 1 week earlier than the control without transplanting and the survival rate increased by 6-12%. Effective stem increased 6-20%, cane yield increased 216-755 kilograms per mu, an average yield of 454 kilograms, an increase of 8-17% yield, an average of 12%, such as sugar prices per ton at 130 yuan per acre deducted The cost of 15-20 yuan, net profit of up to 13-78 yuan per mu.
