摘　　要：In order to find out a new way for environment-friendly and resourcelized utilization of cassava starch processing wastewater, the cassava starch anaerobic fermentation liquid was applied in watermelon production, and its effects on the growth and development, yield and fruit quality of watermelon were investigated. The results showed that the cassava starch anaerobic fermentation liquid significant- ly promoted the vegetative and reproductive growth and improved the yield and fruit quality of watermelon. Compared with conventional fertilization, the application of cassava starch anaerobic fermentation both with COD concentration of 1 200 mg/L according to the amount of 150 t/hm2 promoted the growth of vines and leaves of watermelon plants, brought forward the flowering, fruiting and harvest of watermelon and significantly increased the fruit number, fruit weight, yield, fruit size, fruit shape index, soluble solid content, soluble sugar content, soluble protein content and Vita- min C content of watermelon. At the same time of improving the yield and quality of watermelon, cassava starch anaerobic fermentation liquid was turned into treasure as a liquid fertilizer. This study provides a new ideal for the yield and quality im- provement of watermelon and the wastewater treating of starch factories.为了探明木薯淀粉废液环保资源化利用新路子,开展了木薯淀粉生产中经厌氧发酵后的废液应用于西瓜生产中,并研究其对生长发育、产量和品质的影响。试验结果表明,木薯淀粉厌氧发酵液应用到西瓜生产中能显著促进植株的营养生长和生殖生长,提高产量并改善果实品质。整个西瓜生育期施用COD浓度为1 200 mg/L左右的木薯淀粉厌氧发酵液150 t/hm^2能促进西瓜植株瓜蔓和叶片的生长,使西瓜开花结瓜时间和收获期提前,结瓜数、单瓜重、产量、果实大小、果形指数、可溶性固形物、可溶性糖含量、可溶性蛋白含量和Vc含量都比常规施肥的显著提高。木薯淀粉厌氧发酵液作为一种液肥应用到西瓜生产中可达到提高西瓜的产量和品质并变废为宝的双重目的,可为西瓜增产提质增效和淀粉厂有效解决环保问题提供新思路。
