- 摘要:
- 以收获后的大蒜和油菜秸秆按2∶1(G2R1)、1∶1(G1R1)、1∶2(G1R2)比例制作堆肥茶,以“中农29号”水果黄瓜为试验材料,采用珍珠岩基质栽培,全生长期以Hoagland营养液为植株提供营养,在黄瓜两叶一心后每4 d喷施一次堆肥茶,分别以喷施清水(CK1)、不喷施(CK2)为对照,测定黄瓜生长和果实品质指标,采用隶属函数法进行综合评价,探究叶面喷施堆肥茶在黄瓜无土栽培体系中的应用价值。结果表明:G1R1处理的黄瓜果实品质综合表现最佳,尤其在维生素C含量方面,相比CK1、CK2分别提高了121.60%、465.29%,而可溶性蛋白质含量比CK1低19.05%、比CK2高8.80%;在卫生品质方面,硝酸盐含量分别比CK1、CK2高18.89%、28.09%,亚硝酸盐含量分别比CK1、CK2降低37.84%、41.03%。G1R1处理黄瓜生长指标及产量也较对照表现一定优势。
- Abstract:
- To assess the effect of foliar application of compost tea prepared from garlic and rape plant residues,the growth and fruit quality of cucumber (Cucumis sativus cv.Zhongnong No.29) was evaluated.The compost tea was prepared incorporating various proportions of garlic and rape plant resides as:2∶1 (G2R1),1∶1 (G1R1) and 1∶2 (G1R2).A total of five treatments (proportionately prepared compost tea,spraying with ground water (CK1) and no spraying (CK2)),were applied once in four days interval when cucumber grew to two leaves stage.The subordinate function method was used to comprehensively evaluate the measured fruit quality.The results showed that G1R1 had the best performance on comprehensive fruit quality,especially on the content of vitamin C.Compared with the two controls,the vitamin C content of G1R1 increased by 121.60% and 465.29%.The soluble protein content was 19.05% lower than CK1,but 8.80% higher than CK2.However,the nitrate content was 18.89% and 28.09% higher than CK1 and CK2,respectively.The nitrite content of G1R1 was decreased by 37.84% and 41.03%,respectively.Also,the cucumber plants of G1R1 treatment had better growth performance and production than the controls.
