| 摘 要： | 为探讨莲藕科学施肥方法,2007年进行了钾肥不同用量施肥试验。结果表明：潴育性杂沙泥肉田种植莲藕,施K2O 75～225kg/hm2,增产2 134～17 433kg/hm2,净增收益8 286～68 982元/hm2;潴育性沙泥肉田种植莲藕,施K2O 75～225kg/hm2,增产2 925～17 194kg/hm2,净增收益11 450～68 026元/hm2,可明显增强莲藕抗病性和显著改善品质。但施K2O超过225kg/hm2,莲藕产量和淀粉含量则明显下降。 |

| Abstract: | The fertitization experiment of polassium applicaition amount was conducted to discuss scientific fertilization methods on lotus.The results showed that:on temporary submergic hetero sandy clay fat fields,compared with no-potassium treatment,potassium oxide application amount 75～225kg/hm2 could increase the yield by 2 134～1 7433kg/hm2,and the net income by 8 286~68 982 Yuan/hm2;on temporary submergic sandy clay fat fields,potassium oxide application amount 75～225kg/hm2 could increase the yield by 2 925~17 194kg/hm2,and the net income by 11 450～68 026 Yuan/ hm2;furthermore,potassium application could obviously enhance the lotus disease resistance and remarkably improve the lotus quality,but lotus yield and starch would decrease obviously when potassium oxide application amount more than 225kg/hm2. |
