Problems solved by technology

In terms of forestry planting, my country's forest area is large, widely distributed and the growth environment conditions are complex. In order to solve the problem of afforestation on difficult sites such as arid, semi-arid and water-deficient slopes, and improve the survival rate of afforestation, if artificial watering is used, the investment will be relatively large. , it is more resource-intensive, so most of them rely on rainfall to make plants grow naturally. However, as the drought problem becomes more prominent, only relying on the ability of plant roots to absorb rainfall after rainfall, the growth of plants is relatively slow, especially after transplanting plants. Underdeveloped root system, weak water absorption and water retention capacity, even if transplanted after rainfall, it is difficult to survive

Abstract

The invention discloses a forest tree water retention planting method. The method comprises the following steps of pretreating nursery stocks, preparing a water-retaining agent, deeply planting the nursery stocks, applying the water-retaining agent, and wrapping the trunks. The water-retaining agent comprises plant starch, nano calcium carbonate, gelatin, phosphorus pentoxide, purple shale rock millet and hydroxypropyl cellulose. The method has the beneficial effects that (1) multiple water retention means are provided for comprehensive control, thereby improving the water retention efficiencyand the survival rate of forest trees; (2) the method is simple to operate and easy to popularize; and (3) the method is environment-friendly and free of soil pollution.

Description

technical field [0001] The invention relates to the technical field of tree planting, and more specifically relates to a method for planting trees with water conservation. Background technique [0002] In arid and semi-arid areas, water is one of the main factors restricting the distribution and normal growth of plants. The traditional farming and animal husbandry planting methods are direct transplanting, followed by watering and fertilization; this planting mode is not conducive to water retention and moisture retention of plants. Therefore, when planting in water-deficient dry land, sandy land and slope land, the survival rate of the plant is very low. Over the years, my country has invested a lot of manpower and financial resources in the prevention and control of desertification. In order to solve the problem of plant survival rate in difficult site afforestation areas, scientific and technological personnel have made many active attempts, especially in dryland and semi...
