采用裂区试验设计方法研究栽培方式和施肥处理对黄瓜产量、钾吸收及养分利用效率的影响。结果表明，嫁接黄瓜产量为90631．53 kg／hm2，较自根黄瓜产量增加68．95％；嫁接栽培的钾吸收量极显著高于自根栽培，高出1．03倍，但钾利用效率极显著降低；施用钾肥可极显著提高黄瓜产量，黄瓜产量达81903．88 kg／hm2，较不施钾肥提高31．31％。

The effects of cultivation methods and fertilization on cucumber yield and the characteristic of potassium absorption and utilization were studied by split plot experiment .The results showed that the cucum-ber yield reached 90 631.53 kg/hm2 after grafting, and was 68.95%higher than that of root cultivation .The potassium absorption of grafting cultivation was 1 .03 times that of root cultivation , which reached the very sig-nificant level;but the use rate of potassium was significantly decreased .The cucumber yield was significantly increased by the application of potassium , reaching 81 903.88 kg/hm2 , and increased by 31.31%compared to the treatment without potassium .
