Effects Of Grafting With Loofah As Stock On The Growth.Yield And Quality Of "Ke Nong Er Hao" Balsam Pear

Balsam pear(Momordica charantia L.)is mainly planted in tropical to temperate regions,are more common in the north and South culture in China,is mainly the melons and vegetables.The balsam pear contains many bioactive substances,have remarkable therapeutic effect,application effect and health care efficacy,by the love of the people.In production,is the continuous cropping of balsam pear inevitably,while continuous cropping obstacles will bring a lot of damage to crops,causing great loss of production.As everyone knows,grafting can effectively increase the disease resistance of plant,increase plant root nutrient uptake of water and soil,but also can improve the yield.So The cultivation of vegetable crops,grafting is very important,but also very necessary,and it has already become one of the essential contemporary crop production technology.This technology is currently in the vegetable crops have done a lot of tests,and has also been implemented in the daily production.The rootstock on seed setting rate,vegetables crop resistance has great effect on fruit growth and quality.Pumpkin Seedlings and Loofah seedlings have been used as stock to graft Balsam pear seedlings in the production.loofah seedlings are used as stock in our tests because they are more anti-waterlogging and easy to graft than pumpkin seedlings.This test with"Kenong No.two" as a scion with bitter gourd,gourd as rootstock,grafting yield of inquiry"number two" melon growth,agriculture and disease resistance,impact test results are as follows:(1)The gourd as rootstock "kenong No.two" bitter,bitter gourd seedling grafting each period of stem length and diameter was significantly larger than that of self root seedlings and grafted seedlings of bitter gourd,bitter gourd vine growth advantage late in the process gradually manifested,and the growth of main stem diameter is the main advantage gradually in the early growth of.(2)The gourd as rootstock "kirnon No.two" bitter,bitter melon grafted fruit size,thick flesh and self than bitter gourd,balsam pear showed that grafting significantly better.For improving the "traits Kenong two" bitter gourd fruit has a very significant role.(3)In the same growth period,grafting can obviously improve the Kenong No.two balsam pear yield of grafted seedlings before the late production was higher than that of self root seedlings,and yield of balsam pear are presented at first and then decreased.(4)The incidence of graft Kenong two "of Momordica charantia was significantly lower than that of self root powdery mildew of Momordica charantia,indicating grafting can better reduce the" branch No.two "on the incidence rate of bitter melon powdery mildew,improve resistance.(5)."Conon No.two" bitter gourd can make balsam pear abnormal fruit number,fruit rate has been improved.
