蘑菇菌糠在小白菜上的肥效研究

Study on the Application of Mushroom Culture Medium Residue as Compost for Pakchoi

目的：研究蘑菇茵糠在小白菜上的肥效。方法：试验设3个处理：A常规施肥：腐熟猪粪S00kg／亩、45％（15-15-15）复混肥20kg／亩作基肥，5kg／亩尿素作追肥；B常规施肥＋蘑菇菌糠堆肥：常规施肥的基础上增施蘑菇茵糠堆肥300kg／亩，蘑菇茵糠堆肥在移栽前一次性作基肥施用；C不施肥（CK）。每个处理重复3次，采用随机区组设计。统计各小区产量，同时进行经济性状考察和硝酸盐、糖分含量、维生素C含量测定。结果：增施蘑菇菌糠堆肥能改善小白菜的生物学性状，增产14．5％；小白菜的可溶性糖含量提高14．2％、硝酸盐含量降低19．1％、VC含量提高22．3％。结论：蘑菇菌糠堆肥具有明显的增产和提高蔬菜品质的效应，适宜在蔬菜上推广使用。

Objective：Study on the fertilizer efficiency of Mushroom dregs compost in pakchoi. Meth- odThis test of 3 treatment. A： Conventional fertilization： Fully-fermented pig manure 500kg/Mu, 45% （ 15-15-15 ） compound fertilizer 20 kg/ Mu as base fertilizer use, 5kg/ Mu urea as fertilizer use; B Conventional fertilization with mushroom compost： In conventional fertilization based on the increasing ap- plication of mushroom compost 300kg/Mu, Mushroom compost in before transplanting disposable as basic fertilizer; C No fertilization （ck）. Each treatment was repeated 3 times, using a randomized block de- sign. At the same time, mainly on the economic traits investigation and nitrate, sugar content, vitamin C content determination. Result：In comparison with the check, applying the fermented mushroom dregs to pakchoi could increase fresh yield by 14.5%, the content of soluble sugar by 14. 2%, the content of vi- tamin C by 22. 3%, and could reduce the content of nitrate by 19. 1%. Conclusion：Mushroom compost can obviously increase yield and improve the quality of vegetables effect, suitable for vegetable use.
