Embodiment 1

[0038] Example 1 A method for raising seedlings of Codonopsis pilosula with high yield and preventing diseases and insect pests

[0039] The seedling raising method includes:

[0040] (1) Seed selection and treatment: Codonopsis pilosula seeds must have a net weight of more than 0.31g, a water content of less than 6.12%, a clarity of more than 93%, and a germination rate of more than 87%; choose full, mildew-free, disease-free seeds and place them Soak the seeds in warm water of 40℃~50℃ and 0.3~0.5% potassium permanganate solution;

[0041] (2) Seedling tray treatment: Put the seedling tray in a 100-fold diluted bleaching powder solution, soak for 8-10 hours, and take it out to dry for later use;

[0042] (3) Substrate preparation: Take 40 parts of humus soil, 5 parts of dead silkworm extract, 7 parts of biogas residue fermentation material and 45 parts of lime powder and mix them evenly, and use 2% honey water to control the humidity of the substrate to 30% , Put the matrix into a b...

Embodiment 2

[0048] Example 2 A method for raising seedlings of Codonopsis pilosula for high yield and preventing diseases and insect pests

[0049] The seedling raising method includes:

[0050] (1) Seed selection and treatment: Codonopsis pilosula seeds must have a net weight of more than 0.31g, a water content of less than 6.12%, a clarity of more than 93%, and a germination rate of more than 87%; choose full, mildew-free, disease-free seeds and place them Soak seeds in warm water of 40℃~50℃ and 250 times solution of 50% carbendazim;

[0051] (2) Seedling tray treatment: Put the seedling tray in a 100-fold diluted bleaching powder solution, soak for 8-10 hours, and take it out to dry for later use;

[0052] (3) Substrate preparation: Take 50 parts of humus soil, 15 parts of dead silkworm extract, 8 parts of biogas residue fermentation material and 30 parts of lime powder and mix well, and use 2% honey water to control the humidity of the substrate to 38% , Put the matrix into a bag, and disinf...

Abstract

The invention discloses a high-yield and disease-insect damage preventing seedling growing method for Codonopsis pilosula. The seedling growing method is characterized by including the steps of seed selecting and treating, seedling tray treating, matrix preparing, tray loading, hole pressing, sowing, matrix covering, seedling trays putting in seedbed and seedling stage managing. By means of the method, seedlings emerge fast and are uniform and high in seedling survival rate, and seeds are saved; the seedling age is short, the seedlings are high in quality, root systems are developed and complete and are hurt little during transplanting, the seedlings recover fast, and the harvesting stage comes ahead of time; the seedbed is small in area and convenient to manage and transport; seedling trays and the matrix are disinfected, and therefore the occurrence rate of disease and insect damage is small in the seedling stage. The method effectively increases the Codonopsis pilosula yield and prevents and controls the disease and insect damage.

Description

Technical field [0001] The invention relates to the field of planting technology, in particular to a method for raising seedlings of Codonopsis pilosula with high yield and preventing diseases and insect pests. Background technique [0002] Codonopsis (scientific name; Codonopsis pilosula (Franch.) Nannf.) is a genus of Codonopsis of Campanulaceae, a perennial herb. Codonopsis is a traditional tonic medicine commonly used in China. In ancient times, Codonopsis from the Shangdang area in Shanxi was used as the top grade. It has the effects of nourishing the middle and nourishing qi, strengthening the spleen and lungs. According to modern research, Codonopsis pilosula contains a variety of sugars, phenols, sterols, volatile oils, baicalein glucoside, saponins and trace alkaloids, which can enhance immunity, expand blood vessels, lower blood pressure, improve microcirculation, and enhance hematopoietic function. In addition, it can improve the white blood cell decline caused by che...
