Problems solved by technology

[0002] In the arid and semi-arid areas of northern China, there is little precipitation in autumn and winter, and the soil dehydrates seriously, resulting in low soil moisture content and ground temperature in spring, making it difficult for maize to sow and emerge, which is the main obstacle to maize production in this area; the application of conventional mulching cultivation techniques, although fro

Embodiment Construction

[0009] Choose wheat, corn, potato, bean or green manure land as the front stubble, with deep soil layer, good soil structure, good water seepage and water and fertilizer retention performance, moderate or higher fertility, flat terrain or gentle slope land;

[0010] Soil preparation and mulching before winter to increase moisture: take wheat, corn, potato, beans or green manure land as the previous stubble plot, and apply 3000-5000 kg of farmyard manure per mu as base fertilizer after the previous crops are harvested to sterilize the soil and eliminate insects Then deep plowing; planting in wide and narrow row mode, plot length 6.6m, width 5.5m, row spacing (0.50m+0.80m) × 0.27m, 10 rows per plot, 20 plants per row, 200 plants in total, 2m around the test site Protection row, ridging method: start along the contour line, plant in wide and narrow rows, the width of the row is 80cm, and 2 sowing ditches are first opened with the narrow row of 50cm, most of the soil is scraped to ...

Abstract

The invention discloses a trench sowing cultivation method of corns in a drought area. The trench sowing cultivation method comprises the following steps of carrying out soil preparation and film mulching and increasing moisture before winter, applying a fertilizer and seeding at the beginning of spring, managing at the seedling stage and the middle term, and managing and harvesting at the later stage. In comparison with the regular film mulching cultivation technology, the novel technology has different soil preparation and film mulching time, the annual film mulching cultivation in a furrow starts after harvesting preceding crop (in autumn), film mulching is timely carried out when soil preparation in rain, hole sowing is carried out along the furrow in spring, in comparison with sowing, the film mulching is ahead of time for 5-7 mouths, rainfall in a non-growing season can be stored for a crop growth season, so that the water desorption of soil in autumn and winter is effectively reduced, the temperature of the soil is improved, and soil nutrient is improved to be effective for creating good soil environment for growth of the corns; after many-year experiments, the result shows that in comparison with sowing in spring, by adopting the furrow film mulching cultivation, the moisture content of the soil, which is 0-20 cm under a film, is improved by 6.5-11.5%, the temperature of the soil, which is 5 cm under the film, is improved by 2.5-3.0 DEG C, the yield rate of the corns is improved by 12-25.8%, and the trench sowing cultivation method has better soil moisture conservation, warming and yield increase effects.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a furrow sowing cultivation method for corn in dry areas. Background technique [0002] In the arid and semi-arid areas of northern China, there is little rainfall in autumn and winter, and the soil dehydrates seriously, resulting in low soil moisture content and ground temperature in spring, and difficulties in corn seedling emergence, which are the main obstacles to corn production in this area; the application of conventional mulching cultivation techniques, although from To a certain extent, the ground temperature has been increased, and the effect of moisture conservation has been enhanced, but the problem of poor soil moisture in spring sowing has not been solved. The raised ridges are still not conducive to rain collection and moisture increase. . [0003] The rain-collecting and water-saving cultivation technology on the side of the corn film is a new production and cultivation mo...
