The test results showed that using the mixed substrate of pedite and vermiculite in winter and spring can keep moisture but not too high, and the produced sprout vegetable had good quality and high yield.展开更多

The results showed that： after cutting and pinching, seedlings with multi-lateral branches could be formed. The cutting treat- ment in the container had a small number of seedlings with over 2 lateral buds, and the lateral buds were weak. Some of the weak lateral buds disappeared with the growth going on, showing poor growth performance. The pinching treatment in the sand bed nursery found a large number of seedlings with more than 2 lateral buds, and the lateral buds could grow into lateral branches, forming the T. sinensis seedlings with multi-lateral branches. Proceed to cutting processing, the secondary and third-level lateral branches came into being, which could make the seedlings of T. sinensis have multi-head tree shape in 2-3 years.展开更多
