摘　　要：田间试验表明,高畦栽培西甜瓜对增产和防治德雷疫霉、辣椒疫霉有显著效果:畦作比平作出苗率增加147.9％,植株P_2O_5含量高5.11％,座瓜率增加96.3％,产量增加36.0％～88.4％,烂秧防效达89.2％～92.0％,烂瓜防效达100％。The field experiment indicated that high ridge cultivation of watermelon and melon had an apparent effect upon the yield increase and prevention and control of phytophthora drechsleri and p,capsici of watermelon and melon. Also, as compared with level cultivation) the ridge cultivation of watermelon1 and melon had showed- the rate of emergence was increased by 147.9%; the content of P2O5by5.11%; the percentage of fertile fruit by 96.3%; the yield increase by 36.0%-88.4%; and the control effec t of sar-ment rot was about 89.7% -92.0%, and that of fruit rot about 100%.
