Embodiment 1

[0032] The mulching method of the farmland ridges and furrows for rain-collecting planting of the present embodiment is aimed at the fields where the previous crops of the farmland are flat-planted, and comprises the following steps:

[0033] 1) After the previous crops are harvested, according to the layout of ridges and ditches for rain-collecting planting in the field according to the agricultural production plan, the surface soil at the ridged part is divided to both sides to form a landfill ditch;

[0034] 2) Gather the straw and weeds in the field. The whole straw does not need to be crushed. It is laid in the landfill ditch along the direction of the landfill ditch. Adjust the track of the agricultural machinery in the field so that the wheels of the agricultural machinery can crush the straw and weeds along the direction of the landfill ditch. Form the prototype of the ridge body, and then cover the surface soil cleaned to both sides on the prototype of the ridge body t...

Embodiment 2

[0037] The film mulching method for rain-collecting planting in ridges and furrows of the present embodiment is aimed at the fields where the previous crops are planted for rain-collecting in ridges and furrows, comprising the following steps:

[0038] 1) After harvesting the crops planted in the previous ridges and furrows for rain collection, collect field crop straw and weeds, gather them in the planting ditch of the original ridge and furrow planting system, and adjust the track of the agricultural machinery in the field so that the wheels of the agricultural machinery are aligned with the straw along the direction of the original planting ditch. Weeds and weeds are rolled to form the prototype of the ridge, and then combined with plowing or deep loosening, the soil on the original ridge surface is transferred and covered on the prototype of the ridge to form a new ridge, and the original ridge is reduced to a new planting ditch;

[0039] 2) Eradicate the soil near the jun...

Abstract

The invention relates to a mulching film covering method for farmland ridge-and-furrow rainwater-harvested planting. The mulching film method includes the steps that the surface of a ridge body is covered with a mulching film, and the edge portions, on the two sides of the ridge body, of the mulching film is coiled inward in the direction of the ridge body and fixed. Compared with a traditional mulching film covering method, the mulching film covering method eliminates water stagnation regions formed by film-pressing soil on the film in a joint area of the ridge and a furrow, it is ensured that natural rainwater collected on the mulching film on the side of the ridge completely flows into soil in planting trenches in the farmland ridge-and-furrow rainwater-harvested planting process, fixation of the mulching film can be met, the mulching film is prevented from being uncovered by wind, it can be avoided that the film-pressing soil on the edges of the mulching film blocks, absorbs and dissipates drought-region farmland ridge surface rainwater converged runoff to makes rainwater unavailable, and the rainwater harvesting efficiency of the farmland ridge-and-furrow rainwater-harvested planting technology is further improved.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a film covering method for rain-collecting planting in ridges and ditches in farmland. Background technique [0002] Farmland ridge and furrow rain harvesting planting technology (also called farmland ridge and furrow micro-harvesting planting technology) is an important mode of in-situ enrichment and superposition of farmland rainwater. Planting techniques are organically combined. This technology intercepts the natural precipitation on the ridge surface by forming ridges and covering it with plastic film to form runoff, and uses the characteristics of water flow to the lower part to guide the precipitation on the ridge surface into the adjacent low-cut ditch planting area, which is consistent with the original planting area. The superposition of natural precipitation can improve the soil moisture environment in the root zone of crop growth and development in drylands t...
