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 raising seedlings of Sagittarius under facilities. The utility model belongs to the technical field of agricultural (vegetable) cultivation. Background technique [0002] Arrowhead seedlings are generally raised with soil, river mud, etc. to make a seedbed, and then the top buds of Arrowhead are inserted into the soil or substrate at a certain distance to allow them to germinate and grow. Arthia sativa in early spring protected cultivation uses strong terminal buds as seeds. After the temperature starts to rise in early spring, the seedlings are raised in protected areas in time. When the seedlings are about 15-20cm high, the seedlings are transplanted into greenhouses, greenhouses and other facilities as soon as possible. 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 s...

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
