Problems solved by technology

[0003] The main factor that restricts the growth and survival rate of Mandshurica mandshurica is water. Traditional afforestation methods are not conducive to water retention and moisture retention of plants. Therefore, during afforestation in spring, in case of drought, the survival rate of plants is very low
If the method of artificial watering is used, the investment is relatively large and it consumes more resources. Therefore, most of the plants rely on rainfall to make the plants grow naturally. However, as the drought problem becomes more prominent, only relying on the ability of the plant root system to absorb the rainfall after the rainfall, the plant growth is relatively slow. , especially in the initial stage of afforestation, the root system of the plant is underdeveloped, and the ability of water absorption and water retention is weak. Even if the afforestation is done after rainfall, it is difficult to ensure a high survival rate

Abstract

The invention discloses a fraxinus mandshurica water retention and afforestation method, and belongs to the technical field of water retention and afforestation. The method comprises the following steps of selection of an afforestation land, preparation of a water-retaining agent, soil preparation, seedling selection and transportation, application of the water-retaining agent, afforestation and young forest tending management, wherein the water-retaining agent comprises coconut soil, aloe gel, plant starch, potassium alkyl sulfate and gelatin. Based on the principle of matching site with trees, by applying the water-retaining agent, the method has the beneficial effects that (1) multiple water retention means are used for comprehensive treatment, so that the water retention efficiency andthe afforestation survival rate are improved; (2) the operation is simple and convenient and the popularization is easy; and (3) the method is environment-friendly and does not pollute the soil.

Description

technical field [0001] The invention relates to the technical field of water conservation and afforestation, and more specifically relates to a method for water conservation and afforestation of Mandshurica mandshurica. Background technique [0002] Mandshurica mandshurica is one of the precious broad-leaved tree species in the northeast forest region. It is distributed in the northeast in China, and grows in the eastern Daxinganling, Xiaoxinganling, and Changbai Mountains. It is distributed westward to parts of Qianshan and Yanshan Mountains, as well as parts of Henan, Shanxi, Shaanxi and Gansu. Mandshurica mandshurica has a hard and dense material and beautiful texture. It is a high-grade wood material for industry and civil use. It can be used to make various furniture, musical instruments, vehicles, and machinery. [0003] The main factor restricting the growth and survival rate of Mandshurica mandshurica is water. Traditional afforestation methods are not conducive to ...
