A kind of intensive willow floating seedling raising method and its application

Abstract

The invention provides an intensive willow floating seedling cultivation method. The intensive willow floating seedling cultivation method comprises utilizing a phenolic foam plate serving as a floating carrier, cutting willow cuttings in a high density, placing into a nursery pond, injecting a nutrient solution and replacing the nutrient solution for every 14 days. According to the intensive willow floating seedling cultivation method, willows are rapid in rooting and sprouting and good in growing, willow growing required environment factors such as fertility, temperature and moisture are controlled furthest, willow seedlings are wide, thick and green in leaf, willow root systems are extremely developed, the root fresh weight is 8 to 10 times higher than the earth culture, the integral seedling cultivation period is 3 to 4 months, the seedling cultivation time is greatly reduced compared with the traditional field seedling cultivation, and cultivated willow seedlings are high in drought resisting and anti-water-logging capability, suitable for forestation under a water shortage or water excessive saturation condition. The intensive willow floating seedling cultivation method has the advantages of being strong in operability and practicability, shortening the seedling cultivation time, improving the seedling cultivation density, reducing costs, achieving modernized, industrialized and intensive seedling cultivation in a large scale and providing a large amount of willow seedlings for production and ecological environmental engineering in a short time.

Description

technical field [0001] The invention belongs to the field of plant cultivation and seedling raising, and relates to an intensive willow floating seedling raising method and its application. Background technique [0002] Willow is an important resource plant, and there are about 330 to 500 species in the world. Willow has many uses and has high economic and ecological value. For example, willow can be processed into boards for papermaking, etc. Willow is fast-growing and has a large biomass, which can be used as bio-energy materials. Important energy willow; willow leaves have high nutritional value and can be used as animal feed; many willows have high ornamental value, such as weeping willow, willow with long claws, willow with silver buds, and willow with mosaic leaves. As a pioneer tree species, willow can adapt to harsh habitats, such as dark and humid, flooded, drought, high salinity, and poor nutrition. Willow is fast-growing, easy to reproduce asexually, and has str...

Problems solved by technology

However, conventional field seedling cultivation (mainly conventional soil cultivation) has many disadvantages. It takes up a lot of space and needs to occupy arable land with better soil quality; it is labor-intensive, and cuttings require a lot of manpower, and more manpower and material resources are required for seedling raising. , financial resources; long seedling cycle, high management costs and other shortcomings
