- 摘要:
- 以西瓜为材料,通过水培试验,在EC值相同条件下,研究了沼液与营养液配施对西瓜生长特性、根系活力、产量以及可溶性固形物、可溶性蛋白质、维生素C含量及硝酸盐含量的影响。结果表明:合理配施沼液,能有效改善西瓜品质,提高产量。与单独施用营养液相比,配施稀释16倍沼液处理下西瓜产量显著提高了9.26%,可溶性固形物含量显著增加了1.65%,维生素C含量是对照的1.77倍,增幅显著,硝酸盐含量较对照较低了8.96 mg?g-1。配施稀释16倍沼液的有机营养液,可以有效促进设施西瓜生长,增加株高,促进根系生长,提高设施西瓜产量,改善果实品质。
- Abstract:
- Watermelon was taken as material,through hydroponic experiment,under the same conditions EC value,the biogas slurry and nutrient solution with yield of watermelon,growth characteristics,root activity,and the contents of soluble protein,soluble solids,vitamin C,and the influence of nitrate content were analyzed.The results showed that the nutrient solution suitable for the application of biogas slurry,which could effectively improve the fruit quality of watermelon and increase the yield.Compared with the application of nutrient solution alone,the yield was significantly increased by 9.26%,the content of soluble solids increased by 1.65%,the content of vitamin C significantly increased by 1.77 times under organic nutrient solution with 16 times biogas slurry treatment.Compared to control,the content of nitrate decreased by 8.96 mg?g-1.The organic nutrient solution with 16 times biogas slurry could effectively increase the growth of watermelon,increase plant height,promote root growth,increase watermelon yield and improve fruit quality.
