有机肥能提高西瓜糖分和维生素C含量,降低有机酸,并对西瓜甜味,鲜味、苦味氨基酸组成产生有利影响,从而改善西瓜风味。有机肥与化肥配合的适宜比例,猪粪,鸡粪为60％,麻饼为40％。有机肥(猪粪、鸡粪、麻饼)与化肥配合施用,西瓜产量比对照(等养分)每亩增产60.2～251.2kg,增产率为4.1％～16.3％。有机肥提高西瓜品质及产量的原因,主要是提供养分并促进其平衡,改善西瓜根际环境,促使西瓜早发健壮,提高单瓜重,延长糖分积累时间。另外,有机肥还可调节植株生长点中脱落酸与赤霉素的比例,从而促进西瓜花芽分化,早座果,早成熟。 Organic fertilizer can improve watermelon sugar and vitamin C content, reduce organic acids, and watermelon sweet, umami, bitter amino acid composition had a beneficial impact, thereby improving watermelon flavor. Appropriate proportion of organic fertilizer and chemical fertilizer, pig manure, chicken manure is 60%, 40% of hemp. Organic fertilizer (pig manure, chicken manure, hemp cake) with the application of chemical fertilizers, watermelon yield than the control (nutrient) per mu yield 60.2 ~ 251.2kg, the yield was 4.1% ~ 16.3%. Organic fertilizer to improve watermelon quality and yield of the reasons, mainly to provide nutrients and promote its balance, improve watermelon rhizosphere environment, promote watermelon early and robust, improve the weight of a single melon, prolong the accumulation of sugar. In addition, organic fertilizer can also adjust the ratio of abscisic acid to gibberellin in the growth point of the plant, thereby promoting the differentiation of watermelon flower buds, early fruiting, and early maturation.
