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

Embodiment 1

[0019] Example 1 Seedling cultivation by water insertion

[0020] In the experimental farm of Huajiachi Campus of Zhejiang University, a seedbed of 1.5 m and a depth of 15 cm was constructed, and then a layer of fine sand with a thickness of 5 cm was sprinkled to form the slotting bed. The purpose of sanding was to fix the cuttings. Insert the cuttings (10 cm in length) of dry willow, weeping willow, bark willow, dragon's claw willow, and silver bud willow directly into the sand, and then inject tap water to make the cuttings above the surface of the water. Adventitious roots can be produced by water insertion for 1 week, and then transplanted. Cultivate for a period of time before transplanting for the second time. This method has low seedling reproduction efficiency, tap water is used in the whole process, and the plants can only use their own nutrition to grow during the whole process. After a long time, the seedlings grow poorly (yellow leaves), the leaves are thin, and...

Embodiment 2

[0021] Embodiment 2 cutting seedling raising

[0022] The nursery is located in the experimental farm of Huajiachi Campus of Zhejiang University. The nursery is deeply plowed, and the depth of the plowed field is 20-30cm as a seedbed, and the width of the seedbed is 1.5m. Dry willow, weeping willow, Qi willow, dragon claw willow, silver bud willow, each cutting has 1~2 buds, the length is 10 cm, the spacing between cuttings is 20cm, and the row spacing is 50cm. Put the cuttings directly into the soil and water after cutting . After 1 week, roots and leaves emerged. This method is a common method at present, but the labor intensity is high, the reproduction coefficient is low, and the work range for the final seedling raising is large, which increases the cost of seedling cultivation.

Embodiment 3

[0023] Embodiment 3 Floating Seedlings

[0024] Implemented in the experimental farm greenhouse of Zhejiang University Huajiachi Campus.

[0025] (1) Establish a floating nursery pond. Establish a nursery pool—a cement pool, with specifications of 5 m in length, 0.45 cm in width, and 0.30 cm in depth, with a cement wall thickness of 6 cm. To prevent leakage, the nursery pool should be coated with waterproof paint once.

[0026] (2) For the seedling carrier, choose a phenolic foam board (PF) insulation board with a thickness of 3-5 cm. This foam board is soft, tough, aging-resistant, corrosion-resistant, and has a large bearing capacity. It is easier to operate than polyethylene foam boards.

[0027] (3) Collect the willow branches of the year, such as dry willow, weeping willow, willow, willow, willow, silver-bud willow, etc., with a thickness of 0.5-1cm, full buds, neat branches, no pests and diseases, and cut them into cuttings with a length of 10-15cm. , according to 15...

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...
