Water-retaining seedling raising device and seedling raising method

Abstract

The invention discloses a water-holding seedling cultivation device and a seedling cultivation method. The water-holding seedling cultivation device is a column composed of an outer wall, an inner wall, a closing cover and a base, the center of the column is columnar planting hole, and the periphery of the column is an annular cavity water storage chamber. The outer wall and the base are made of waterproof materials, the inner wall is made of slow release water materials, and the closing cover is made of seepy materials. The seedling cultivation method includes the steps that the planting hole is filled with seedling cultivation matrixes, and then seedling cultivation is carried out by utilizing the seedling cultivation device; after seedling cultivation, seedlings and the seedling cultivation device are integrally placed in the planting hole dug in advance; after soil is covered and trampled, the seedlings are watered for the first time, and then a normal maintenance stage can be started. The water-holding seedling cultivation device is easy to manufacture and low in production cost, can be used for industrialized seedling cultivation, has a slow release effect on water, improves the utilization rate of the water, reduces the watering frequency, lowers the maintenance cost, can supply the water required for growing of the plants to the plants for a long time and improves the survival rate of the seedlings; vegetation can be recovered quickly, and the effect is obvious.

Description

technical field [0001] The invention relates to the field of vegetation restoration, in particular to a water-retaining seedling raising device and a seedling raising method. Background technique [0002] Drought is a worldwide problem. The total area of ​​the world's continental arid and semi-arid regions is about 48 million square kilometers, accounting for one-third of the continental area, covering more than 50 countries and regions on all continents of the world. Areas with annual precipitation less than 200 (or 250) mm are usually classified as arid areas, and areas with annual precipitation of 200 (or 250) to 500 mm are classified as semi-arid areas. [0003] my country is one of the main arid countries in the world, about 42% of the country's land area is in arid and semi-arid areas. 83% of the arid and semi-arid areas are distributed in the Northwest of China, so drought is the most important climate feature and natural disaster in the Northwest. [0004] The main...

Problems solved by technology

During the construction of greening projects in arid and arid areas, due to climatic conditions, it is very difficult to plant green seedlings

The main problems are: (1) The climate is dry, the rainfall is low, and the rainfall is concentrated in July to August; (2) The evaporation is large, water replenishment is difficult, and the survival rate of plants is low; (3) The soil moisture content is low and the soil hardness is high

[0006] In summary, the above technical measures have more or less certain problems in the process of utilization, or the design is complicated, or the production cost is expensive. Therefore, in production practice, it is difficult to use them on a large scale
