Methods of Raising Bamboo and Willow Seedlings in Arid Areas

Abstract

The invention discloses a method for growing bamboo and willow seedlings in arid areas, which mainly includes sand bed preparation, burying, spraying water, branching and post-branching management. Then the branches are cut off to become individual seedlings, and then cultivated into seedlings under certain water and fertilizer conditions. Compared with the prior art, the present invention builds a micro-environment by sprinkling irrigation to raise seedlings in batches, and the seedlings raised are strong and uniform in size, without rooting agent or rooting powder treatment, but the root system of the plant is more than the seedlings raised by bamboo willow microplant propagation and seedling technology. 2 to 3 roots, so the plants have strong growth, especially the high reproduction coefficient, which is generally more than 8 times that of conventional cutting seedlings. The degree of intensification is high, manpower and material resources are saved, and the emergence rate per unit area is high.

Description

technical field [0001] The invention relates to a method for raising bamboo and willow seedlings, in particular to a method for raising bamboo and willow seedlings in arid areas. Background technique [0002] Bamboo willow is a new willow hybrid variety. After years of breeding and domestication, its shape, side branches, and dense planting are similar to bamboo, so it is named Bamboo willow. [0003] On the basis of inheriting many advantages of traditional willow species, bamboo willow further improves the fast-growing and resistance of the species. Bamboo willows are widely used, and are often used as industrial raw material forests, large-diameter timber, street trees, landscaping, and farmland shelterbelts. [0004] Most of the western regions belong to arid or semi-arid regions, especially Xinjiang region. Due to the special natural and geographical environment, some problems have been encountered in the introduction of bamboo and willow, and the fast-growing nature o...

Problems solved by technology

[0005] For example, in the area around the Taklamakan Desert in Xinjiang, the sunshine time is long, the temperature is high, the winter is cold and the summer is hot, the temperature difference between day and night is large, it is windy and dry and hot, and the frost-free period is long. Erosion, the upper cuttings of bamboo and willow cuttings will dry up quickly and gradually spread below the ground, causing the cuttings to dry out and die

In the cuttings with branches and leaves, although the leaves are curled, the skin of the cuttings exposed on the ground and the new branches is still green. Although the cuttings in the soil have taken root, there are many brown spots on the skin. Most of them are single root, the above situation makes the growth potential of cuttings weak and the survival rate is low

[0006] Bamboo willows germinate early. After the weather warms up and the ice and snow melt, bamboo willows have germinated. At this time, the nursery is muddy and people and vehicles cannot enter the ground. The conventional measure is to cut off the stems and fix the planting to ensure survival, which virtually delays the annual growth of bamboo willows and has a negative impact on the fast-growing and high-yield bamboo and willows.
