摘要
为探寻减肥条件下西瓜的施肥配方,研究了4个不同施肥处理(T_(1),不施肥料;T_(2),常规施肥;T_(3),在常规施肥基础上减施30%化肥;T_(4),木霉菌生物有机肥+减施30%化肥)对西瓜产量与品质的影响。试验结果表明,施用木霉菌生物有机肥可显著增加西瓜植株的株高、茎粗、叶片SPAD值以及果实可溶性蛋白、可溶性糖、VC含量;产量、产值均以T_(4)处理最高,收益比T_(1)高2210.61元/667 m^(2)。建议西瓜生产采用木霉菌生物有机肥配施减量30%化肥的高产可持续施肥配方。
In order to provide theoretical basis for scientific application of trichoderma and rational application of fertilizer in watermelon production,the effects of four different fertilization treatments(T_(1),no fertilizer;T_(2),conventional fertilization;T_(3),30%reduction of compound fertilizer;T_(4),30%reduction of compound fertilizer+trichoderma)on the yield and quality of watermelon were studied.The results showed that the plant height,stem diameter,chlorophyll content,yield,soluble protein content,soluble sugar content and vitamin C content of watermelon could be increased effectively by applying trichoderma.T_(4) treatment had the highest yield and output value,and its output value was 2210.61 yuan/667 m^(2) higher than that of T_(1).It is suggested to adopt the high yield,high quality and sustainable fertilizer formula of 30%reduction of compound fertilizer and trichoderma combined application in watermelon production.
