Climate: It is a typical tropical tree species that likes high temperature and rainy, calm and fertile soil.
Three. Technology: The main technical measures are:
1. Select the appropriate rubber plantation, divide the environmental types and match the varieties. Aiming at the two limiting factors of rubber planting in China: low temperature and typhoon, the adaptability of rubber trees to environmental conditions was studied. Different rubber planting areas are divided into large, medium and small environmental types, and different varieties are configured in each type area.
2. Breeding disease-resistant and high-yield varieties. At present, the wind-resistant variety Haiken 1 and the cold-resistant variety 93- 1 14 have been popularized in production, and the latter has a short-term low temperature of MINUS one degree.
3. Wind-resistant and cold-resistant cultivation techniques. Wind-resistant cultivation technology is to choose different sizes of shelterbelts, trim and shape them, and plant them reasonably close; Cold-resistant cultivation techniques mainly include ditch seedling raising, overwintering by bud grafting with stems, drought-resistant planting in early spring of next year, wide row and close planting, etc.
4. Rubber picking technology suitable for northern planting. According to the climatic characteristics of different rubber planting areas in China, the rubber picking technology combining tube, tillage and cutting and the dynamic analysis of rubber production were implemented.
