Method for improving walnut rhizosphere ecological environment in stony desertification area

Abstract

The invention discloses a method for improving a walnut rhizosphere ecological environment in a stony desertification area. The method comprises the following steps that step 1, land modification is carried out; step 2, seedling selection and field planting are carried out; step 3, a mode is built; step 4, a water collecting funnel is built; and step 5, wormcast fertilization is carried out. The method for improving the walnut rhizosphere ecological environment in the stony desertification area is safe and reliable, crop waste is processed into earthworm feed, a large amount of wormcast is produced after earthworms eat the earthworm feed, chemical fertilizer is replaced with the wormcast, and the purposes of improving the physical and chemical properties of soil in the walnut rhizosphere in the stony desertification area, promoting crop root development and reducing water and soil loss are achieved. According to the method for improving the walnut rhizosphere ecological environment in the stony desertification area, the pollution load of agricultural waste to the environment is relieved, weight and pesticide are reduced, the wormcast which is a novel biological organic fertilizer containing a large number of nutrient elements and organic matter is used, the crop yield is increased, the quality of agricultural products is improved, continuous cropping obstacles of crops can be relieved, and soil-borne diseases are controlled.

Description

Technical field [0001] The present invention relates to the field of ecological environmental improvement, in particular a method of ecological environmental improvement of walnuts around a desertification area. Background technique [0002] Since the soil nor in the rocky desertification area, the soil loss is serious, so there is a certain requirement for the ecological environment improvement in the rocky desertification area, Guangxi Fengshan is committed to building a walnut production, but the walnut is mainly grown in the rocky desertification area. The production of nutrients and soil erosion is facing the problem. Walnut production is mainly with food crops corn, economy crop soybeans, vegetable crop pepper and Chinese herbal medicines such as "vegetables + fruit forest model" ecological environment improvement methods; however, in crops There is a large number of straws to be treated after harvest, and a large amount of fertilizer is used in crop planting, and there wil...

Problems solved by technology

[0002] Due to the poor soil nutrients and serious soil erosion in rocky desertification areas, there are certain requirements for the improvement of the ecological environment in rocky desertification areas. Fengshan, Guangxi is committed to building a large walnut production county, but walnuts mainly grow in rocky desertification areas. Facing the problems of nutrient infertility and soil erosion in production, walnut production is mainly interplanted with grain crops corn, cash crop soybeans, vegetable crops pepper and Chinese medicinal materials, and the ecological environment improvement method of "vegetable + fruit forest model" is adopted; however, in crop After harvesting, there is a large amount of straw to be treated urgently, and a large amount of chemical fertilizers will be used to increase production during crop planting, which will have a certain impact on the environment; therefore, it is very necessary to invent a method for improving the ecological environment of walnut rhizosphere in rocky desertification areas at this stage of
