我们曾于一九五五年总结了群众甘蔗育苗移栽的经验,但仅从提早甘蔗下种出发,未考虑到蔗区冬种面积大,相当一部份春植蔗是套种在麦田中,这样既不能下基肥,又不能提早下种,也限制了今后机械种植的应用.特别是甘蔗发芽成苗阶段处于小麦的荫蔽之下,出苗率低,缺苗严重,土壤坚实,蔗苗细弱,产量不高.前作小麦,因受要套种甘蔗的限制,也无法采用先进技术和高产的晚熟品种.在套种甘蔗时,还常常折断了部份小麦.在拌泥浆套种甘蔗时,又造成麦田过湿,违反了该时小麦成熟不宜多水的原则,一般小麦要损失10～20%.收割小麦和处理麦茬时,也可能损伤一部份蔗苗.若待麦收后播种,甘蔗则嫌太迟,产量和含糖分都会降低.群众埋怨说:“种蔗损麦”,“收麦伤蔗”.为了解决这些矛盾,我们从重新参考以往的研究资料,认真总结群众分兜、移预备苗补缺穴的经验,以提高复种指数和最大限度地提高单位面积的光能利用率作为研究出发点,根 We had summed up the experience of the masses of sugarcane seedling transplanting in 1955, but only from early sugarcane under the species, did not consider the sugarcane area winter species area, a considerable part of the spring planting of cane in the wheat field, This will neither under the base fertilizer, but also can not be planted earlier, but also limits the future application of mechanical planting.Particularly sugarcane germination stage is under the shadow of wheat, the emergence rate is low, lack of seedlings serious, solid soil, thin sugarcane seedlings, Yield is not high.Formerly wheat, because of the need to intercropping sugar cane restrictions, can not use advanced technology and high yield of late-maturing varieties.In the intercropping of sugarcane, often also break some of the wheat.When mixed with sugar cane straw, but also caused the wheat field over Wet, in violation of the principle of wheat should not mature when the water is more, the general loss of 10 to 20% of wheat. Harvest wheat and wheat stubble, it may also damage some of the cane seedlings. , The output and sugar content will be reduced.People complain that: “Cane damage wheat”, “harvest wheat cane.” In order to solve these contradictions, we re-reference to previous research data, earnestly summarize the crowd points pocket, Points of experience to improve complex Index and maximize the utilization of light energy per unit area as a starting point for research, root
