Seeking the planting method of tobacco covered with plastic film

Tobacco plastic film mulching planting method: soil preparation and ridging requires consistent ridge spacing, flat ridge surface, fine broken soil and no stubble. The distance between ridges is 100cm, the distance between plants is 50cm, and there are 20000 seedlings per hectare. Timely early planting plastic film tobacco should be planted early, effective use of accumulated temperature, generally from May 1 to 10. The bottom water should be thoroughly watered when planting tobacco. Mulch plastic film immediately after planting, in order to increase temperature and preserve soil moisture. When covering the film, the film should be stretched and paved, compacted and compacted to ensure no air leakage. After mulching, plough the soil once and press both sides of the plastic film strictly. Field management constantly check the film after planting, if there is ventilation place should be compacted in time, so as not to run away moisture and breed weeds. And when the temperature in the seedling film is as high as 38 ℃ and lasts for more than 3 hours, punch the hole above the film in time to ventilate and cool down. In the absence of frost, 60% of the tobacco seedlings were covered with plastic film. Draw the tobacco seedlings out of the film, cultivate the roots with soil, and then seal the film around with fine soil. If tobacco seedlings are found to be de-fertilized, it can be combined with seedling irrigation and fertilization. Uncover the film when the flue-cured tobacco grows to the late stage of the group plant and the early stage of vigorous growth. To remove the film, weeding and soil cultivation should be carried out at the same time, and then plough once. Extra-root topdressing is due to high soil temperature, fast decomposition of nutrients, good growth of tobacco plants and large amount of fertilizer in plastic film mulched tobacco field. In order to ensure the nutritional demand of tobacco plants, extra-root topdressing was carried out in the early stage of vigorous growth according to the growth trend after the film was opened. Spray 2.25kg urea per hectare, dissolved in 187.5 kg of water. To shovel soil and plastic film smoke once, you should do two shovels, two shovels, and three shovels. That is, the ridge and ditch before the film is opened, the temperature is raised and the cold is dispelled; after the film is uncovered, the soil cultivation is carried out at the same time; once in the prosperous period, the soil height should reach more than 25 cm.
