甘蔗地的合理轮、间、套种,是甘蔗高产、高糖、提高亩蔗地经济效益,改土增肥,培养地力的重要措施。据我区1986年30万亩甘蔗的统计,其中新植蔗16.5万亩,轮栽豆类的占8.2万亩,薯类4.5万亩,与水稻轮栽的3.5万亩。经过多点抽样调查,轮栽的甘蔗亩产增1～1.5吨,增产20～40％,豆类亩增10～20公斤,薯类增200～300公斤,水稻年亩增50～100公斤。蔗行间套种面积达19.2万亩,占甘蔗面积64％,甘蔗亩增0.2～0.5吨,间种花生的亩收干荚25～40公斤,高产的
Reasonable sugarcane rotation, intercropping, intercropping, is sugarcane high yield, high sugar, improve the economic benefits of mu cane, soil improvement and fertilizer, an important measure to cultivate fertility. According to the statistics of 30 million mu of sugarcane in 1986 in our district, the newly planted sugarcane was 165,000 mu, the planted legumes accounted for 82,000 mu, the potatoous plant 4.5 million mu, and the 35,000 mu paddy planted. After more sampling survey, rotation of planted sugar cane mu produced by 1 to 1.5 tons, an increase of 20 to 40%, beans mu by 10 to 20 kg, potato increased by 200 to 300 kg, mu in rice increased by 50 to 100 kg. Intercropping area of cane lines up to 192,000 mu, accounting for 64% of the area of sugarcane, sugarcane mu by 0.2 to 0.5 tons, intercropped peanuts acres harvest pods 25 to 40 kg, high yield
