Annual mulching film full coverage old film peeling and new film replacing fertilization and seeding integral method for dry farming regions

Abstract

The invention relates to an annual mulching film full coverage old film peeling and new film replacing fertilization and seeding integral method for dry farming regions. The method comprises the following steps that (1) land parcels are selected; (2) composite microbe organic fertilizers are uniformly spread on the land surface; (3) complete lands are divided; (4) mulching films are mulched on all land surfaces; (5) the soil is sterilized; (6) seeds are selected; (7) the seeds are stirred; (8) the dibble seeding planting is carried out at proper time; and (9) in the dry farming regions with the altitude below 2000m, the mulching films are reserved after the crop harvesting in the first year, the seeding is carried out on the original mulching films in the second year, the mulching films are reserved after the crop harvesting, the old mulching films are peeled off to mulch new mulching films during the seeding in the third year, meanwhile, the fertilization, soil sterilization and dibble seeding integral planting is carried out; and in dry farming agriculture regions with the altitude being 2000 to 2300m, the mulching films are reserved after the crop harvesting in the first year, the old mulching films are peeled off to mulch new mulching films during the seeding in the second year, and meanwhile, the fertilization, soil sterilization and dibble seeding integral planting is carried out. The method provided by the invention has the advantages that the rainfall utilization rate of the dry farming agricultural regions can be greatly improved, in addition, the mechanical operation can be realized, the planting work procedures are reduced, the labor is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a fertilization and seeding method in a dry-farmed area, in particular to an integrated method for fertilizing and seeding in a dry-farmed area with annual full coverage of plastic film, removing the old and replacing it with a new one. Background technique [0002] Gansu Province is located in the northwest inland, and the continental temperate semi-arid climate determines that the climate in this area is dry, with little rainfall, large evaporation, insufficient water and low precipitation utilization rate are the bottlenecks that restrict agricultural production for a long time. The traditional plastic film mulching cultivation technology has suppressed the ineffective evaporation of soil moisture to a certain extent, but in general, the soil is bare, and a large amount of soil moisture still evaporates ineffectively, which has not fundamentally solved the problem of precipitation use efficiency. The full-film double-furrow ...

AI Technical Summary

Problems solved by technology

The full-film double-furrow sowing technology realizes full-surface mulch coverage and greatly improves the utilization rate of precipitation. However, due to the advance time of mulching and the delay of sowing time, the entire cultivation process is complicated and labor-intensive, and it is difficult to realize mechanized operation; The mulching time of plastic film is only from June to October, and the soil is bare for 2 to 6 months of the year, and a large amount of soil moisture still evaporates during this period
