Water retention and soil fixation method for citrus orchard in mountain area

Abstract

The invention relates to the field of agriculture, and discloses a water retention and soil fixation method for a citrus orchard in a mountain area. The method comprises the steps that 1, ditching andridging are conducted according to the fruit tree line spacing being 1.5-3.5 m; 2, in early October, drilling planting is conducted in the sickle alfalfa, broad bean and vulpia myuros c.gmelin mixingsowing mode, wherein the sowing rate of sickle alfalfa is 10-20 kg/ha, the sowing rate of broad beans is 50-80 kg/ha, and the sowing rate of vulpia myuros c.gmelin is 10-25 kg/ha; 3, after sowing iscompleted, the surface of soil is covered with rice straw, wherein the dosage is 2,500-5,000 kg/ha; 4, from April to June in the next year, the sickle alfalfa, broad beans and vulpia myuros c.gmelin are harvested and all covered and subjected to earth backing. Accordingly, the method is suitable for a new-cultivating orchard in the mountain area in South China, the water and soil loss of the soilcan be effectively reduced, the water retention and fertilizer conservation capacity of the soil is increased, physical and chemical properties of the soil are improved conveniently, and rapid growthof fruit trees is promoted.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for water retention and soil stabilization for mountain citrus orchards. Background technique [0002] Soil erosion is one of the important environmental problems in our country and even in the world. Soil erosion leads to the decline of land productivity, the aggravation of flood and drought disasters, and the deterioration of ecological environment, which in turn affects the sustainable development of the region. With the development of social economy, a large amount of newly reclaimed land is developed and utilized, and the new soil erosion caused by man is relatively serious. Therefore, how to prevent and control soil erosion has become a major problem to be solved urgently in the current agricultural environmental protection work. [0003] Most orchards in mountainous areas in southern my country are planted on hills, and planting fruit trees is the most common land use ...

Problems solved by technology

Using green manure crops to cover the soil of new orchards can effectively reduce the area of ​​bare land, greatly reduce soil erosion, and improve the ecological environment. However, there is currently no scientific method for the prevention and control of water, soil, nitrogen and phosphorus loss in orchards in southern my country.
