摘要
黄瓜嫁接以奶瓜作砧木，可起到与黑籽南瓜砧类似的防病增产作用，并具有独特的抗热效果。津杂2号、津研4号、津春4号的奶瓜嫁接苗对枯萎病、霜霉病防效达94．4％、86．5％、95．3％，防效与黑籽南瓜嫁接苗的相当。三个接穗品种前期产量奶瓜嫁接苗比黑籽南瓜嫁接苗分别低8．0％、12．8％、32．4％，而总产量则分别高6．5％、10．8％、8．6％。经电导率测定，三个接穗品种奶瓜嫁接苗抗热性比黑籽南瓜嫁接苗分别高出15．3％、20.0％、13．6％。
Grafted with 'Nai Gua', the yield,disease and hot resistance increased in cucumber. The cucurnber variety of Jin Za No. 4, Jin Yan No. 4, Jin Chun No. 4 seedlinus were grafted with' Nai Gua'The rate of prevention and control of downy mildew and blight were 94. 4 %, 86. 5 %, 95. 3 % respectively as malabar gourd' s. And its early yield was lower thanthe malabar gourd's, but total yield higher.Plastmembrane permeability were higher than that grafted with malabar gourd's 15. 3 %, 20. 0 %, 13. 6 %respectively.
