Laborsaving cost-reducing direct-seeding cultivation method for tobacco

Abstract

A laborsaving cost-reducing direct-seeding cultivation method for tobacco includes firstly, preparing a tobacco field and making beds one month and a half in advance, applying base fertilizer along a bottom center line of each ride, making ridges, and allowing rainwater to supplement the ridges until soil moisture is sufficient; secondly, making holes after the rain stops, and applying plant ash mixed with soil insect drug into the holes; thirdly, sowing seeds in the holes with one seed for each hole, spraying isolane to the plant ash and the coated seeds, allowing the plant ash and the coated seeds to absorb water and become humid, and covering with mulch; fourthly, making holes on the mulch when each seed germinates and grows two leaves and a core, applying fertilizer again into root holes with tobacco plants when tobacco seedlings grow about 20cm tall, filling the holes with soil, removing the mulch when the tobacco plants grow 50cm tall, hilling the beds till the ridges are full, controlling disease and pest damage, timely toping and picking buds, and harvesting for baking timely till the plants are ripe. The method omits the procedures of seedling raising, transplanting and topdressing, and accordingly planting time is shortened, peat and seedling trays are economized, and a seedling tunnel is omitted.

Description

technical field [0001] The invention belongs to a flue-cured tobacco cultivation method. Background technique [0002] Flue-cured tobacco is an important economic crop in my country, with an annual planting area of ​​more than 1 million hectares. At present, flue-cured tobacco planting mainly adopts the method of raising seedlings first and then transplanting. The whole process mainly includes raising seedlings, plowing the land, ridging, fertilizing, transplanting, covering film, preventing and controlling diseases and insect pests, topping and wiping, harvesting and baking, etc. The link is time-consuming, labor-intensive, and labor-intensive. Among them, the seedlings are raised mainly in two ways: floating seedlings and tray wet seedlings. Seedlings need to build greenhouses or plastic sheds, and the seedling stage takes about two months. The substrate used for seedlings is mainly peat (also called peat). Flue-cured tobacco planting mainly adopts ridge farming. The rid...
