Method for cultivating salt willow

Abstract

The invention relates to a method for cultivating a salt willow. The method comprises the following steps of: selecting seedlings of a salix willow, a rose willow and a bamboo willow in spring; planting the salix willow, the rose willow and the bamboo willow in a mixed mode; selecting the salix willow and the rose willow of which braches are turned from light green into dark green or light red in the second year of the spring; cutting the branches which turn light green into dark green or light red into branch sections and cutting the branch sections; shifting the seedlings which are cut at an interval, cutting the branches of the remained seedlings and leaving the strongest branches in the third year of spring; and enabling the remained seedlings to grow to the salt willow in the third year of the autumn. The salt willow obtained by the method is high in survival ratio of planting, straight in trunks, dense in leaves, strong in roots, high in salt and alkali resistant ability, and good in greening effect; the crown is umbrella-shaped; and the generation of willow catkins and the damage to the environment are avoided.

Description

technical field [0001] The invention relates to a method for cultivating willows, in particular to a method for cultivating saline-alkali-tolerant salt willows, and belongs to the field of agricultural technology. Background technique [0002] Common willow has been widely used as a greening plant. However, because common willows are not resistant to salt and alkali, it is difficult to grow them on saline-alkali soils. They can only be planted on ordinary non-saline-alkali soils. Ordinary willows will produce a large number of catkins, which will affect the environment. [0003] At present, the salt-alkali-tolerant plants are usually shrubs, such as Tamarix. Due to their relatively low height, the effect of windbreak and sand fixation is not ideal. The surrounding environment is polluted and the greening effect is poor. In the present invention, the so-called salt willow refers to saline-alkali-tolerant willow. Contents of the invention [0004] The technical problem to...

However, because ordinary willows are not resistant to salt and alkali, it is difficult to grow them on saline-alkali land. They can only be planted on ordinary non-saline-alkali land. Ordinary willows will produce a large number of catkins, which will affect the environment.
