Technical Field
The invention relates to the technical field of agricultural planting, in particular to a method for raising seedlings of actinidia valvata dunn by cutting.
Background
The kiwi fruits are widely favored due to the unique flavor, rich in vitamin C, multiple mineral nutrients, effects of clearing intestines and invigorating stomach and the like, and become one of important fruits. China is the origin of most of Actinidia Lindl germplasm resources, and the cultivation area of Chinese kiwi fruits is the first place in the world. At present, the seedling progeny of delicious kiwi fruit is mostly adopted for breeding kiwi fruit seedlings as stocks, and the kiwi fruit seedlings have many defects, such as poor seedling growth consistency, poor saline-alkali resistance and waterlogging resistance of the seedling stocks, and the like, so that the selection of the stocks with good resistance and growth becomes a key for improving the quality of the kiwi fruit seedlings. The Actinidia valvata Dunn is a kind of Actinidia chinensis, has developed root system, has good waterlogging resistance and saline-alkali resistance, can be produced in large scale, and can be used as stock of Actinidia chinensis seedling.
The asexual propagation can maintain stable inheritance of characters, and the cuttage is one of important means for carrying out the asexual propagation. At present, in kiwi fruits, a technical method for raising seedlings by cutting is provided in actinidia arguta and other kiwi fruits, but the genetic background of the kiwi fruits is greatly different from species to species.
Therefore, providing a method for raising seedlings of actinidia valvata dunn by cutting to promote the healthy development of the actinidia valvata dunn industry is a problem to be solved urgently by technical personnel in the field.
Disclosure of Invention
