Hedge earth bank ridge-direction pitting field having functions of conserving water, soil, nitrogen and phosphorus and cultivation method

Abstract

The invention relates to a hedge earth bank ridge-direction pitting field having functions of conserving water, soil, nitrogen and phosphorus. The field comprises ridges and multiple earth banks, and the ridges comprise ridge bodies and furrows; the multiple ridge bodies and the multiple furrows are arranged in parallel and at intervals; multiple earth banks are arranged in each furrow in the extending direction of the corresponding furrow, and each earth bank is provided with a hedge. The invention further relates to a cultivation method of the ridge-direction pitting field. The cultivation method comprises the steps of measuring the slope and length of the field; making selection between downslope ridge culture or cross-slope ridge culture according to the measured slope and length, and arranging the multiple furrows and ridge bodies, wherein the furrows and the ridge bodies are arranged in parallel and at intervals; arranging the multiple earth banks in each furrow in the extending direction of the corresponding furrow; planting plants on each earth bank for forming the corresponding hedge. According to the hedge earth bank ridge-direction pitting field and the cultivation method, the hedges are reasonably arranged, the stability and firmness of the earth banks are improved, meanwhile, the water, soil, nitrogen and phosphorus conservation effects are greatly improved, the water and soil conservation effect is made to be more ideal, environmental benefits are achieved, and meanwhile economic benefits are combined.

Description

technical field [0001] The invention belongs to the direction of farmland soil cultivation under the jurisdiction of the discipline of farming system. In particular, the invention relates to a field with hedgerows, ridges, and ridges of plants with the function of water and soil nitrogen and phosphorus conservation and its cultivation method. Background technique [0002] The ridge direction area field is to build soil ridges in the furrows at intervals along the direction of the ridges on the slopes of the ridges, so that the rainfall runoff can be blocked and stored on the spot, and the rainwater confluence can be prevented from being scoured along the furrows. [0003] There are mainly following defects in the existing ridge-oriented field fields: [0004] 1. The stability of the soil ridge is not enough. In case of heavy rain or continuous rain, the accumulated water in the ditch is easy to wash away the soil ridge, triggering the domino effect, resulting in greater ero...

Problems solved by technology

[0004] 1. The stability of the soil ridge is not enough. In case of heavy rain or continuous rain, the accumulated water in the ditch is easy to wash away the soil ridge, triggering the domino effect, resulting in greater erosion at the bottom of the slope, leading to more serious soil erosion. This is the current ridge The main problems urgently needed to be solved by Xiang Ward

[0005] 2. Because the soil ridge is affected by various uncertain factors such as rainfall, soil quality and geographical conditions, it is impossible to correctly select a reasonable distance between the soil ridges, resulting in an ineffective interception effect of rainfall runoff

[0006] 3. The cost is high, and the construction of ridges on the ridge to the field has only environmental benefits, no economic benefits, and increases the total farming cost input, such as seeds, sowing, stubble removal, etc., and may also affect crop field management

Mainly plant branch-like shrub plants. The main reason why it is not suitable for farmland application is that the large above-ground parts affect the growth of crops, the interlacing of roots affects soil cultivation and produces strong nutrient competition with crops, and also affects crop sowing, harvesting and intertillage. At the same time, the agricultural economic value of the plants in the hedgerow technology for water and soil conservation is not great, and the aboveground parts are thick and difficult to be cut and crushed by machinery and cannot be returned to the field, which hinders the use of the hedgerow technology in the farmland. application in
