通过一个主试验和多点表证示范研究甘蔗施用糖厂酒精废液的肥料效应。结果表明,糖厂酒精废液中的养分对甘蔗有一定的增产增糖作用,但是产量差异未达显著水平;地膜覆盖比施酒精废液增产作用大,经济效益好。 A main experiment and demonstration of multi-point table were used to demonstrate the fertilizer effect of sugar cane alcohol waste liquor. The results showed that the nutrients in sugar alcohol waste liquor could increase the sugar content of sugarcane, but the difference of yield did not reach the significant level. The plastic film mulching had bigger effect than alcohol waste liquor, and had good economic benefit.
