Flue-cured tobacco planting, as a "short-term, fast and reliable" hot industry, is suitable for planting and development in many rural areas of China and has become a sustainable development industry that many tobacco farmers are willing to accept.
Here is a detailed introduction to the cultivation methods of flue-cured tobacco:
The direct seeding cultivation method of flue-cured tobacco can save labor for seedling raising, transplanting and topdressing; Shorten planting time; Save peat and seedling tray; Save the nursery greenhouse. It was invented by Guizhou Tobacco Research Institute and published in China National Intellectual Property Administration on 20 12,10,21. The operation points of this method are as follows:
Step 1: Arrange the tobacco fields and unpack them one and a half months in advance, apply base fertilizer along the center line of the ridge bottom, then ridging, and wait for rainwater to supplement the moisture in the ridge until the soil moisture is sufficient.
Step 2, punch holes after the rain stops, and apply plant ash mixed with underground insect repellent in the holes.
Step 3, sow seeds in holes, sowing/kloc-0 seeds in each hole, and then spraying transplanting agent into the holes until plant ash and the coated seeds are wet, and covering with plastic film.
Step 4, when the seeds germinate and grow to two leaves with one heart, make holes in the film; when the tobacco seedlings grow to 20 cm high, apply fertilizer again, apply fertilizer to the holes in the roots of tobacco plants, and fill them with soil; after the tobacco plants grow to 50 cm high, uncover the film and cultivate the soil, prevent and control pests and diseases, timely top-wipe the buds, and timely harvest and bake them after maturity.
