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

Abstract

The invention relates to the field of agriculture, and discloses a water retention and soil fixation method for a pear orchard in a mountain area. The method comprises the steps that 1, ditching and ridging are conducted according to the fruit tree line spacing being 2.0-3.8 m; 2, in early October, drilling planting is conducted in the rapes for fertilizer use, white clover and alfalfa mixing sowing mode, wherein the sowing rate of rapes for fertilizer use is 4-8 kg/ha, the sowing rate of white clovers is 8-20 kg/ha, and the sowing rate of alfalfa is 10-25 kg/ha; 3, after sowing is completed,the surface of soil is covered with rice straw, wherein the dosage is 2,000-4,000 kg/ha; 4, from early April to late May in the next year, the rapes for fertilizer use, white clover and alfalfa 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 soil can 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 growth of fruit trees is promoted.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for water conservation and soil stabilization for mountain pear 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 southern my country are planted on hills, and planting fruit trees is a common land use method. However, newly cult...
