| 摘 要： | 通过田间试验,比较研究了在细砂土和粉壤土两种质地的土壤上,cu、Mo、Si营养对苦瓜产量和品质的影响.结果表明,与对照相比,在细砂土上施Cu能显著提高苦瓜产量,而施Mo、Si未表现出明显的增产作用;在粉壤土上施Si极显著提高了苦瓜产量,而施Cu、Mo未表现出明显的增产效果.在细砂土上施Cu、Mo极显著降低了苦瓜硝酸盐含量,而施Si未降低硝酸盐含量;在粉壤土上施Cu、Mo、Si均使苦瓜硝酸盐含量显著或极显著降低.在两种质地的土壤上施Cu、Mo、Si对Vc含量没有明显的影响;在细砂土上施Cu、Mo、Si极显著提高了可溶性糖含量,在粉壤土上施Cu、Mo亦极显著提高了可溶性糖含量.本试验结果表明在不同的土壤质地上Cu、Mo、Si营养对苦瓜的增产效应和品质改善效应不同.

| Abstract: | Effect of Cu, Mo and Si fertilizers on balsam pear (Momordica charantia) yield and quality were studied in two different textural soils. The results showed that compared with CK, Cu fertilizer had significant effect on the yield in fine sand soil but no evident effect with application of Mo and Si fertilizers. Cu or Mo fertilizers in silt loam soil had not significant effect on the yield compared with CK, however, the yield increased obviously when Si fertilizer applied in silt loam soil. The content of nitrate nitrogen significantly decreased by 19.15% ~ 43.35% with application of Cu or Mo fertilizers but no evident effect with Si fertilizer applied in fine sand soil. The content of nitrate nitrogen decreased when Cu, Mo, Si fertilizers applied in silt loam soil. The diversity of nitrate content between microelement fertilizer treatment and comparison was significant in the silt loam soil (p<0.01). Application of microelement fertilizer had no significant effect on the content of vitamin C in the two textural soils. The water-soluble sugar contents increased in the two textural soils with Cu or Mo fertilizers. The contents of water-soluble sugar in fine sand soil and silt loam soil increased by 85.40% ~ 148.68% and 27.72% ~ 65.31%, respectively. However the sugar content decreased significantly with application of Si in silt loam. The results showed that application of Cu, Mo, and Si fertilizers in different textural soils had different effect on yield and quality of balsam pear. |
