猪场粪污源大量元素水溶肥料在叶菜上的肥效研究

Influence of macroelements water soluble fertilizer with pig wastes addition on leaf vegetables yields and qualities

为研究一种以猪场粪污为原料的新型大量元素(含微量元素Cu)水溶肥料的应用效果,采用田间小区试验,通过设置清水对照、等养分单质肥料和猪场粪污源大量元素水溶肥料3个处理,研究施用供试大量元素(含微量元素Cu)水溶肥料对不同试验点叶菜产量、叶绿素和Vc含量的影响。结果表明:施用猪场粪污源大量元素(含微量元素Cu)水溶肥料增加了叶菜的产量、叶绿素和Vc含量,与清水对照相比,叶菜产量增产幅度为5. 50%～41. 43%,叶绿素和Vc含量分别提高5. 59%～24. 53%和7. 14%～35. 71%;与等养分单质肥料相比,叶菜产量增产达6. 64%～19. 16%,叶绿素和Vc含量分别提高1. 93%～13. 96%和6. 52%～26. 67%。可见,该新型大量元素(含微量元素Cu)水溶肥料的施用可以有效提高叶菜产量,并改善其品质,值得推广应用。

A field experiment was conducted to study the effects of macroelements water soluble fertilizer (microelements type) with pig wastes addition on leaf vegetables yields and qualities.In this experiment,three treatments including water,equal nutrient single fertilizer,and new macroelements water soluble fertilizer with pig wastes were assigned to study their effects on the vegetables yields,chlorophyll and Vc contents,so as to evaluate the effects of the new water soluble fertilizer on vegetables yields and qualities.The results showed that the new fertilizer enhanced the yields and qualities of the leaf vegetables.In detail,compared with the water treatment,the yield of the treatment added with the new fertilizer increased by 5.50%-41.43%,the chlorophyll and Vc contents increased by 5.59%-24.53%and 7.14%-35.71%,respectively;compared with the equal nutrient single fertilizer,the yield increased by 6.64%-19.16%,the chlorophyll and Vc contents increased by 1.93%-13.96%and 6.52%-26.67%,respectively.Therefore,the application of the new water soluble fertilizer with pig wastes addition is beneficial for improving the yield and quality of the leaf vegetables,and is worthy of extensive application.
