Protected Sagittaria sagittifolia seedling raising method

Abstract

The invention relates to a protected Sagittaria sagittifolia seedling raising method, which belongs to the technical field of agricultural (vegetable) cultivation and includes: building a level bed in an insulation facility, and making sure that ridges around the bed are higher than the same; spreading a plastic film on the bed top and the ridges to form a water storage tank; filling the water tank with fresh water; pouring selected terminal buds of Sagittaria sagittifolia into the water tank, raking well to lead the terminal buds to densely float in the water, and making sure that each terminal bud is partially immerged in the water while being partially exposed; erecting an arch shed over the level bed, covering the arch shed with one layer or a plurality of layers to achieve thermal insulation and increase; guaranteeing sunlight to guarantee photosynthesis of leaves of seedlings; and when interior temperature of the facility ready for transplanting reaches more than 15 DEG C, picking out the seedlings which are 20-25cm high, separating mutually entangled roots, and transplanting the seedlings. The method is simple and easy, pest and disease damage in seedling period can be prevented effectively, labor and seedling land are reduced, roots of the seedlings are rich, the roots of the seedlings are less apt to break in lifting before transplanting, and the seedlings can quicklyrecover to grow after transplanting.

Description

technical field [0001] The invention relates to a method for cultivating seedlings in a Cigu facility. It belongs to the technical field of agricultural (vegetable) cultivation. Background technique [0002] Cigu seedlings are generally first made of soil, river mud, etc. to make a seedling bed, and then the Cigu terminal buds are inserted into the soil or matrix at a certain distance to allow them to sprout and grow. In the early spring facility cultivation of Cigu, the sturdy terminal buds are used as seeds. After the temperature starts to rise in early spring, the seedlings are raised in protected areas in time. When the height of the seedlings is about 15-20cm, the small seedlings are transplanted and transplanted to greenhouses, greenhouses and other facilities as soon as possible. However, there are often germs, insect eggs, grass seeds, etc. in the soil, which may cause diseases, insects and weeds in the seedling stage, affecting the growth of Cigu seedlings; the ins...

AI Technical Summary

Problems solved by technology

However, there are often germs, insect eggs, grass seeds, etc. in the soil, and there may be diseases, insect pests and weeds in the seedling stage, which will affect the growth of Sagittarius seedlings; terminal bud insertion requires more labor and high cost; after insertion at a certain distance, 1 mu Generally, the seedbed can only be used for 10-20 mu of field transplanting, and there is more land for seedling cultivation
