[0027] The preparation method of the special cultivation medium for Chinese herbal medicines used (refer to ZL 201410228080.6):
[0028] 1) Preparation of the mother seed of the strain: take the waste bacterial sticks after cultivating shiitake mushrooms, black fungus, ganoderma and other wood-rot fungi, remove the plastic bag, and use it as the raw material of the strain after being crushed; add 0.5-3% of the weight of the raw material of the strain Brown sugar, 3~10% wheat bran, 2~8% corn flour, 1~7% ammonium bicarbonate, 3~15% superphosphate, stir evenly in a blender and use it as a strain compound material; Trichoderma living spores powder (effective number of viable bacteria ≥ 10 9 cfu / g) and the strain compound material are fully mixed at a weight ratio of 1:1000~1500, covered and fermented with a white plastic film for 15-20 days to obtain the mother seed of the strain; the fermentation conditions are: pH value 7~8, CO 2 The concentration is 0.5%, the cultivation tempe...
Embodiment
[0033] A method for ecological prevention and control of Huazhonglou rhizome rot, the specific steps are as follows:
[0034] 1) Base selection
[0035] Under-forest bases choose broad-leaved forests and mixed forests near water sources, with good irrigation and drainage, and deep humus, canopy density of 40-60%, and altitudes of 500-1500m; field bases choose well-drained, good soil texture, rich in humus , slightly acidic dry land. After the Huazhonglou products are excavated, the planting plots will be idle for 2 to 3 years.
[0036] 2) Seedling propagation:
[0037] a) Preparation of seeds and seedlings: From early to mid-November, harvest ripe berries with red skin, stack and ferment the berries, rub and rinse them, sort out plump and undamaged seeds, and mix the seeds and fine river sand by weight ratio Mix evenly at a ratio of 1:3, store at 3-5°C for 2-3 months to keep the seeds moist; combine it with a special cultivation medium for Chinese herbal medicines (prepared...
