Study on the selection of grafted rootstocks of Tiwei watermelon
To screen for Tiwei watermelon rootstock varieties with good grafting affinity,good symbiosis,high survival rate,and strong disease resistance,Zaojia 8424 variety was used as a control.There are three types of rootstocks:gourd type,pumpkin type,and wild type,field experiments were conducted to determine the survival rate,disease resistance,yield and soluble sugar content of grafted seedlings after harvest.The results showed that there was a great difference in the survival rate of grafted watermelon seedlings among different rootstocks.The 9 grafting combinations had a good comprehensive character,the survival rate was 98.5%,and the grafting affinity was good,the incidence of fusarium wilt was 1.7%,the total 667 m2 yield was 4303.70 kg,the central sugar content was 12.2°,the edge sugar content was 9.2°,the hollow rate was 0.The rootstock Sizhuang 7 is suitable for grafting of Tiwei watermelon,and can be recommended as a grafted rootstock for promotion in Cixi City.
