| 摘 要： | 试验研究了平衡施肥对大白菜产量和品质的影响.结果表明,在CK(N15P5K10)基础上分别增施氮肥、磷肥、钾肥、硼肥、有机肥都可使大白菜产量提高5.3%～47.0%,并以施用泥炭的效果最为显著.与CK相比.仅常规施肥的大白菜硝酸盐含量降低;不同施肥处理均提高了大白菜维生素C舍量,且以常规处理增幅最大.达121.9%;增施氮肥、硼肥和有机肥大白菜的氨基酸舍量增加,以氮肥的效果最佳,增幅为26.4%.增施氮肥、磷肥、泥炭和菜籽粕处理的还原糖含量增加;硼肥和磷肥处理可提高大白菜的氮含量,增幅分别为10.4%和9.2%,增施磷肥提高了大白菜的舍磷量,增幅为17.7%,钾肥和硼肥处理提高了大白菜的含钾量,增幅分别为6.3%和2.6%.不同肥料组合对大白菜N/P,N/K,P/K作用不一致.

| Abstract: | A field plot experiment was carried out to study the effect of balanced fertilization on field and quality of Chi- nese cabbage. The results indicated that yield of Chinese cabbage was significantly increased by 5.3%-47.0% by further adding nitrogen, phosphorus, potassium and organic fertilizers on the basis of N15P5K10. Addition of peat to Chinese cab- bage produced the best. Compared with CK, nitrate nitrogen content reduced when applying conventional fertilizer. VC were all increased in different treatme... |
