摘要
以普通白菜早生京华为试材,研究了沼渣与复合肥配比对普通白菜产量、品质及土壤肥力的影响。结果表明:用适当比例沼渣代替基肥中的复合肥,植株的各项生长指标以及产量均明显优于单一施用复合肥,与单一施用复合肥相比,普通白菜的可溶性糖、VC、可溶性蛋白含量均显著增加,硝酸盐含量显著降低;在基肥中添加不同比例的沼渣,土壤中的有机质、全氮、全磷、全钾含量均显著增加。用一定比例沼渣代替复合肥作基肥,可促进普通白菜生长,改善品质,提高土壤肥力,本试验中以沼渣40%+复合肥60%的配比效果最好。
Using pakchoi〔Brassica campestris L.ssp.chinensis(L.)Makino var.communis Tsen et Lee〕'Zaoshengjinhua'as material,this experiment studied the effects of different ratios residue-to-compound fertilizer on the growth,yield and quality of pakchoi and soil fertility.The results showed that using appropriate proportion of residue to instead the basal fertilizer,the indexes of growth and the yield of the plants were much better than by using fertilizer alone.Compared with using fertilizer alone,the soluble sugar,VC and soluble protein contents of pakchoi were significantly increased;while its nitrate content decreased significantly.Adding appropriate proportion of residue to basal fertilizer could increase the contents of organic matter,total nitrogen,total phosphorus,total potassium in soil.This study indicates that adding appropriate proportion of residue to instead compound fertilizer can promote the growth of pakchoi,improve its quality,and increase soil fertility.In this experiment,the treatments of 40% residue + 60% fertilizer has the best effect.
