Method for cultivating corn through plastic film mulching

Abstract

The invention discloses a method for cultivating corn through plastic film mulching. The method includes the following steps that, (1), soil preparation is carried out, wherein soil is deeply scarified for 30-35 cm in the middle ten days of March firstly, it is most ideal to add a certain amount of organic fertilizer, then rotary tillage is carried out 1-2 times, and the soil and the fertilizer are mixed to be uniform; (2), ridging and mulching are carried out; (3), mulches are punched; (4) seeds are treated, wherein before being sown, the corn is treated with a seed coating, after the corn isstacked for 3-6 hours, the corn is mixed with fungicide, and the corn is sown after seed dressing is completed; (5), the treated seeds are put in punched holes in the mulches, and the seeds are covered with soil by one cun while being sown; (6), seedlings are selected and complementarily planted, wherein when seedlings grow to 2-3 leaves, weak seedlings are removed and strong seedlings are reserved, the seedlings are thinned at the three-to-four-leaf period or final singling is carried out at the five-to-six-leaf period, and the seedlings are checked and complementarily planted in time; (7),field management is carried out; (8), corn harvesting is carried out. By means of the method, the problems that the limitation of the altitude exists, meanwhile, manual seedling digging cultivation isneeded, and a method is complex and low in efficiency are solved.

Description

technical field [0001] The invention relates to the technical field of corn cultivation, in particular to a method for cultivating corn covered by plastic film. Background technique [0002] The existing domestic corn cultivation methods are usually sowing in March of the current year and harvesting in June; or sowing in July of the current year and harvesting in October, or sowing in the winter of the current year and harvesting in February of the next year . The method is to plant ridges and sow seeds in the plain areas with low altitude and in Hainan area, and harvest the corn after it matures through conventional field management. demand, due to the tenderness of corn seeds, it is prone to lack of seedlings and broken seedlings, and there will be a market blank in July to August. 15°C), drought or heavy rain, the above-mentioned cultivation method cannot be used in areas with higher altitudes; meanwhile, the above-mentioned method needs to go through the step of manual...
