AI Technical Summary

Benefits of technology

This patented technology has been developed by researchers at home or abroad that involves selecting crops like maize and angelicas from crop species such as rice and sunflower without compromising their ability to resist damage caused by environmental factors like droughts, disease vectors, insect attacks, etc., which could lead to poor yields on these crops. By utilizing this method, farmers have gained more income while reducing harmful chemical inputs used during growing processes compared to traditional methods.

Problems solved by technology

The technical problem addressed in this patents relates to finding ways to reduce or eliminate damage caused from soil errosion during construction works over long periods of time without causing environmental concerns like increased risk of runoff rainwater accumulation. Existing methods involve adding expensive materials that may be harmful when applied indiscriminately due to their negative impacts upon ground vegetative biodiversity (Gibberti et al., 2004). Therefore, an improved method called biological treatment is needed to improve soil quality while minimizing these drawbacks.

Embodiment 1

[0018] 1) Soil preparation and basal fertilizer application: Choose a slope with an altitude of 200-800m, well-drained, deep soil, loose and fertile, humus-containing soil or sandy soil, plow 25-30cm deep, apply 1500kg of farmyard manure per mu, and level the soil Thin, made into a 100-180cm wide flat furrow, with three furrows;

[0019] 2) Sowing: Corn is sown in the middle and early May. When sowing corn, 7 grams of diammonium phosphate is applied to each hole. Mix it with fine sand, sprinkle it evenly, cover with soil, and cover with straw. With every 5 belts as a unit, plant three rows of Angelica dahurica between every two rows of corn. The distance between corn plants is 90cm, and the row spacing is 160cm.

[0020] 3) Intertillage and weeding: manual weeding is adopted, corn is weeded 3 times in May, July and August every year; Angelica dahurica is weeded 3 times in October every year, March and May of the next year;

[0021] 4) Water management: keep the soil water conten

Abstract

The invention discloses a method for preventing and controlling water and soil loss of a sloping field by intercropping corn and angelica dahurica, and belongs to the technical field of water and soil environment protecting and crop planting.According to the method, the corn and angelica dahurica which are high in stress resistance, good in water and soil conservation effect and obvious in economic benefit are finally selected for intercropping through massive screening, bio-organic fertilizer is taken as main fertilizer in the planting process, sunlight, rainwater, land saving and the interdependence relation between the plants are fully utilized, the efficient and ecological modes such as grain (the corn) and medicine (the angelica dahurica) intercropping, tall-short matching and shading for growth promoting are adopted, the plant canopy density is increased, the water and soil loss is decreased, and nitrogen and phosphorus loss is controlled and reduced; meanwhile, the disease and pest damage resistance of the grain and the medicine is improved, the yield is increased, and the good ecologic and economic benefits are achieved.
