本试验根据1973年7月在广东省召开甘蔗科研协作会议布置,我场过去未有宿根习惯,也没有经验。1974年开始试验,面积0.25亩,品种纳印310,设有五个处理:盖牛粪、盖土杂肥、盖猪粪、盖河砂,以不盖为对照。随机排列,没有重复。甘蔗于11月8日收获,11月9日覆盖,厚度2市寸。1974年3月31日开垄亮蔸,4月7日培土压蔸一次,出苗后田间管理同一般大田。从宿根蔗苗期调查五个处理中,以盖牛粪的表现最好,盖土杂肥、盖猪粪的表现次之,盖河砂的较差,不覆盖的(对照)表现最差。实践证 According to the arrangement of sugarcane research collaboration meeting held in Guangdong in July 1973, this experiment had no habit of rooting and no experience in the past. Test began in 1974, an area of ​​0.25 acres, the Indiana varieties 310, with five treatment: cover cow dung, cover Tuza Fei, cover pig manure, cover River sand, to not cover as a control. Random arrangement, no repetition. Sugarcane was harvested on November 8, covering November 9, with a thickness of 2 inches. On March 31, 1974, the ridge was opened brightly and the soil was pressed on April 7 once. After the emergence of the field management, the fields were generally the same. Among the five treatments, the cow dung showed the best performance, followed by pig manure covered with pig manure, followed by pig manure, and the poor and uncovered (control) hatch sand had the worst performance.
