Shandong Changyi Bureau of Agriculture from 1988 to 1999 with vermiculite, perlite, sawdust, river sand four kinds of substrates for the grape hot-cuttage test. Laboratory temperature is not higher than 7 ℃, in order to prevent the shoot bud germination. Cuttings for the 1-year-old Beijing show grapevine branches, length 15cm, keep 2 buds. The heat source is an electric blanket, and the temperature of the base of the cuttings is measured after being energized for 15 hours. The temperature of the four kinds of substrate cuttings was respectively 25.5 ℃ and 2
