Embodiment 1
[0026] A method for improving flue-cured tobacco breeding process and efficiency, comprising the following steps:
[0027] S1. Seed pretreatment: process the foreign crops mixed in tobacco seeds, weed seeds and remove biological impurities, use light, heat and electricity to suppress pathogenic bacteria, keep the seeds healthy, and put the selected plump seeds into cloth bags, After soaking the seed coat, put it into 2% formalin solution for disinfection, take it out after soaking for 10 minutes, and rinse it with clean water;
[0028] S2. Local seedbed preparation: choose a flat, sunny place, where the ground temperature rises quickly, close to the water source, and easy to manage, eradicate weeds, and clean the site;
[0029] S3. Low-density seeding: plant 1000 plants per mu, and the planting method is mainly single-row high-box planting; the ridge width is 67cm, the furrow width is 33cm, and the plant spacing is 60cm;
[0030] S4. Water tray breeding and planting: a water ...

Abstract
The invention discloses a method for improving the flue-cured tobacco breeding process and efficiency. The method comprises the following steps of S1, seed pretreatment, S2, local seedbed preparation,S3, low-density sowing, S4, water disc type breeding and planting, S5, fertilization, S6, drought early blossoming management and S7, selfing and seed harvesting. Pathogenic bacteria are inhibited byutilizing light, heat, electricity and the like, seeds are kept healthy, selected full seeds are put into a cloth bag, seed coats are soaked, and put into a formalin solution, after sterilizing, theseeds are taken out, and the seeds are washed out through clean water; the weather is predicted preliminarily, so that the cultivation risk is reduced; then soil preparation and planting are conducted, and tobacco seeds are reasonably planted; a water disc is designed to carry out rapid water flow irrigation control over the land area of seedlings, so that the development and use of the seedling water quantity in different time periods are ensured; then fertilization is conducted, organic matter, vermiculite, perlite and medical stone are used for processing and preparing matrix fertilizer, and healthy seedling raising use is guaranteed; and seedling management and disease treatment are performed on tobacco cultivation, so that the tobacco breeding quality is improved.
Description
technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a method for improving the process and efficiency of flue-cured tobacco breeding. Background technique [0002] Tobacco is an annual herbaceous plant of the family Solanaceae. Roots can synthesize nicotine. Plant height 1-3 meters. The stem is erect, and each leaf axil has axillary buds, which can germinate into branches. The leaves are alternate and arranged in a spiral shape. The planting parts of tobacco leaves can be divided into five parts: the lower 2-3 leaves of the tobacco plant are called foot leaves; the upper 4-5 leaves are called lower second shed leaves; the middle 4-6 leaves are called waist leaves ; The 4-5 leaves in the middle are called the upper second shed leaves; the 3-4 leaves at the top of the tobacco plant are called the top leaves. The foot leaves and the lower two shed leaves are collectively called the lower leaves, and the u...
