Efficient Grafting Technologies for Intensive Seedling Production of Small Fruit Watermelon in Early Spring
Grafting technology of seedlings directly affects watermelon production and fruit quality.In order to improve the comprehensive technical level of intensive seedling production by grafting of watermelon under low temperature conditions in early spring,and to improve the output ratio of high-quality seedlings,the efficient grafting technologies of small fruit watermelon in early spring were introduced from the aspects of key technologies of grafting such as selection of improved varieties,treatment of substrate,sowing,grafting of long-aged seedlings,healing management,prevention and control of seedling diseases,strong seedling standards,and grafting seedling packaging and transportation.Key technologies such as directional seeding,dry seed direct seeding and disinfection,long-aged seedling grafting,light and temperature supplementation were integrated,which could achieve an increase in grafting efficiency of 400%,an increase in uniformity of 10%,an increase in strong seedling rate of 28%,and an increase in grafting survival rate from 80%to more than 95%.
