Embodiment Construction

[0017] figure 1 It is a schematic diagram of the cultivation method of the present invention. As a specific embodiment of the water-saving irrigation and early germination cultivation method for corn of the present invention, the following steps are included.

[0018] First, ditch the large and small row spacing alternately on the flat ground, sow corn seeds, the sowing depth is 5cm, wherein the large row spacing is 70cm, and the small row spacing is 50cm, sowing till the ridge head.

[0019] Second, after sowing, fill the ditch with a cover device to ensure that the cover soil is of the same depth.

[0020] The 3rd, scrape soil: scrape off the soil layer above the seed and above the small row with agricultural implements, and the width of the soil layer scraped off is guaranteed to be greater than the width of the small row spacing.

[0021] Fourth, watering: Instead of using water pumps to irrigate one row at a time, each individual small amount of water is poured into eac...

Abstract

The invention discloses a water-saving irrigation and early germination cultivation method of corns, which is characterized by comprising the following steps of: (1) ditching a flat land, and alternately sowing corn seeds in large and small rows, (2) covering with the soil, and filling and leveling up after sowing, (3) scraping off 2-3cm soil layers from above the seeds and the small rows with a farm tool, and (4), watering and irrigating shallow ditches formed after scraping the soil, wherein the large row spacing is 70-75cm; the small row spacing is 45-50cm; the sowing depth is 4.5-5.5cm; and the width of each scraped soil layer is greater than the small row spacing. With the adoption of the method for cultivating the corns, the seedling emergence after the corns are sown is one or two days earlier, and the effect of saving irrigation water by above 60% can be achieved.

Description

technical field [0001] The invention relates to a corn cultivation technology, which belongs to the field of agricultural cultivation technology, in particular to a water-saving irrigation and early germination cultivation method for corn. Background technique [0002] In the usual corn cultivation techniques, it takes a long time for corn to emerge after sowing, generally about 5 to 6 days. After the corn is sown, the irrigation method of water pumps is usually used to irrigate one row and one row, so that the amount of irrigation water is relatively large. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a corn water-saving irrigation and early germination cultivation method compared with the usual corn cultivation technology. [0004] In order to solve the above technical problems, a water-saving irrigation and early germination cultivation method for corn of the present invention comprises the following steps...
