木薯淀粉厌氧发酵液对南瓜生长发育、产量及果实品质的影响

为了探明木薯淀粉废液的环保资源化利用新路子,以蜜本南瓜为试验材料,开展了木薯淀粉厌氧发酵液对南瓜生长发育、产量和果实品质的影响研究。结果表明,施用木薯淀粉厌氧发酵液能显著促进南瓜植株的营养生长和生殖生长,提高产量并改善果实的品质。施用木薯淀粉厌氧发酵液能显著促进植株主蔓和叶片的生长,增加叶片叶绿素含量,单株结瓜数、单瓜质量和产量均比常规施肥对照提高50%以上,其果实大小、果形指数、可溶性固形物、可溶性糖、可溶性蛋白、淀粉含量和VC含量也比对照显著或极显著提高。木薯淀粉厌氧发酵液可作为追肥在南瓜生产中应用,达到变废为宝、提高南瓜产量和品质的双重目的。

Effect of Cassava Starch Anaerobic Fermentation Liquid on Pumpkin Growth，Yield and Fruit Quality

In order to ascertain the new resource utilizating way of cassava starch waste for environmental protection，this paper studied the effect of cassava starch anaerobic fermentation liquid（ CSAFL）on pumpkin growth，yield and fruit quality，taking‘ Mibennangua’ as experimental material．The results showed that applying CSAFL could significantly promote the vegetative and reproductive growth，increase pumpkin yield and improve its fruit quality． Using CSAFL could also remarkably promote the growth of pumpkin main stem and leaves，increase leaf chlorophyll content. Besides，its fruit setting number per single plant，single fruit weight and yield were higher than that of the contrast by over 50%. Its fruit size，fruit shape index，contents of soluble solid，soluble sugar，soluble protein，starch and VC were significantly or very significantly increased than that of the contrast．Therefore，CSAFL can be used as additional fertilizer in pumpkin production，so as to realize the dual purposes of turning waste into wealth，and improving pumpkin yield and quality.
