摘要
以5个西瓜品种为试材,通过不同的猪、牛、羊粪有机浸提液配比设置了3个有机营养液配方处理,品种和营养液二因素组合共15个处理(T1~T15),测定各处理西瓜的单果质量、果形指数、产量及可溶性固形物、Vc、可溶性蛋白、可溶性糖、还原糖含量共8个指标,比较各处理间上述指标的差异,运用因子分析的方法对各处理产量和品质指标进行综合评价,从中筛选得到高品质的有机营养液和品种组合。结果表明:营养液和品种耦合对各处理西瓜品质指标的影响极显著;T9处理(即品种Z3与配方P3耦合的处理,用Z3P3表示,下同)还原糖含量最高,为57.7 mg·g^(-1),T7处理(Z3P1)还原糖含量最低,为26.0 mg·g^(-1);T6(Z2P3)、T13(Z5P1)处理可溶性糖含量最高,分别为33.6、33.9 mg·g^(-1),T7(Z3P1)处理可溶性糖含量最低,为14.5 mg·g^(-1);T6(Z2P3)处理可溶性固形物含量最高,为14.0%,T15(Z5P3)处理可溶性固形物含量最低,为11.4%;T5(Z2P2)处理Vc含量最高,为16.7 mg·100g^(-1),T4(Z2P1)处理Vc含量最低,为9.7 mg·100g^(-1)。利用因子分析得到得分排名前3的处理是T9(Z3P3)、T11(Z4P2)、T6(Z2P3)。当施用有机营养液配方3时,2011WH0045、2011WH0053两个西瓜品种产量及品质较好,当施用有机营养液配方2时,2011WH0057西瓜品种产量及品质较好。
To select high-quality organic watermelon varieties,choose appropriate nutrient solution combinations and provide theoretical basis and technical support for organic watermelon cultivation,five watermelon varieties were used as test materials and three organic nutrient solution formulations were created by mixing different amounts of organic extracts from pig,cow and sheep manure in this study.There were 15 treatments(T1~T15)combined with varieties and nutrient solutions.Eight indexes of single fruit quality,fruit shape index,yield,soluble solid,Vc,soluble protein,soluble sugar and reducing sugar were measured.The differences of the above-mentioned indexes among the treatments were compared.The yield and quality indexes of each treatment were evaluated by factor analysis and from which high-quality organic nutrient solution and variety combination were selected.The results showed that the coupling of nutrient solution and variety had a significant effect on the quality indexes of watermelon.The content of reducing sugar in T9 treatment(That is,the treatment of the coupling of the variety Z3 and the formula P3,represented by Z3P3,the same below)was the highest with 57.7 mg·g^(-1),and the content of reducing sugar in T7 treatment(Z3P1)was the lowest with 26.0 mg·g^(-1).The content of soluble sugar in T6(Z2P3)and T13(Z5P1)treatment was the highest with 33.6 mg·g^(-1) and 33.9 mg·g^(-1) respectively.The content of soluble sugar in T7(Z3P1)treatment was the lowest with 14.5 mg·g^(-1).The soluble solid content of T6 treatment was the highest with 14.0%,and that of T15(Z5P3)treatment was the lowest with 11.4%.The content of vitamin C in T5(Z2P2)treatment was the highest with 16.7 mg·100g^(-1),and the content of vitamin C in T4(Z2P1)treatment was the lowest with 9.7 mg·100g^(-1).Using factor analysis,the top 3 treatments were T9(Z3P3),T11(Z4P2)and T6(Z2P3).When organic nutrient solution formula 3 was applied,the yield and quality of 2011WH0045 and 2011WH0053 watermelon varieties were better.When organic nutrient s
