Ramie plastic film covering cultivation techniques
First, film 1. Covering time: The spring temperature can be covered with film when the ground temperature stabilizes at 5°C (or 10~15 days before the date of suitable sowing). In Shandong, it is usually appropriate to use in mid-March. 2, plastic film specifications: generally better to cover a single line, northwest irrigation area can also be used to cover a double-line method. Because the ground temperature after the mulching can be increased by 3~7°C and the growth and development of ramie are promoted, the spacing of mulching film should be increased correspondingly. In order to save investment, ultra-thin polyethylene film or low-pressure polyethylene high-density film with a width of 60~70cm can be used. 3, filming methods: mulch film covering castor generally take the first method after sowing. The mulching film is covered with a laminating machine with a flat film, and after the laminating machine presses the film, it forms a ridgeback and a ditch. Spring rainy areas can be planted by means of ridge-covered membranes, which is conducive to drainage and waterlogging. Second, sowing 1. Sowing time: The sowing time of mulch-covered ramie is 5-7 days longer than that of non-mulching ramie, avoiding early emergence due to early planting and high ground temperature, and encountering frost-free seedlings that are exposed to frost. 2, sowing method: In accordance with the provisions of spacing, in the middle of the film with a small shovel to cut the mulch 5 to 10 cm, depth 2 to 3 cm, broadcast 2 to 3 seeds, and then shovel with fine shovel to cover the seeds of fine soil, pressure Actually, this method saves seedlings, soil pressure and other procedures, which is conducive to the emergence of castor seedlings and cotyledons, and is conducive to the acquisition of seedlings and seedlings. Third, management (see ramie cultivation technology points).
