Embodiment 1

[0026] Use the above-mentioned nutrient solution to float the Panax notoginseng seeds in November, and the seedlings will emerge in March of the next year, and they will emerge in April. The seedlings grow vigorously and are free from diseases and insect pests. After growing for one year, the seedlings are transplanted. Using the nutrient solution, Panax notoginseng grows robustly, and the rhizomes are significantly longer and thicker than those cultivated in soil, about 15%.

[0027] Through this nutrient solution production technology, the root system of Panax notoginseng seedlings is developed, and the plants grow in good condition, which provides a guarantee for improving the quality of Panax notoginseng seedlings and commodities, and promoting the development of the Panax notoginseng industry. cost-effective technology.

Embodiment 2

[0029] Use the above-mentioned nutrient solution to carry out floating seedling cultivation on the seeds of Chonglou in February-March, and the seedlings will emerge in April, and the seedlings will emerge in May. After growing for 2 years, it is transplanted in autumn. Using the nutrient solution, the chrysanthemum grows vigorously, and its rhizome is larger than that cultivated in soil.

Abstract

The present invention relates to a preparation method of a floating seedling nutrient solution for Chinese herbal medicine plant. The nutrient solution comprises macroelements, trace elements, ferric salt and nettle liquid. The macroelements include ammonium nitrate, potassium nitrate, calcium chloride, magnesium sulfate, calcium nitrate and potassium dihydrogen phosphate; the trace elements include manganese sulfate, zinc sulfate, copper sulfate, ammonium molybdate and boric acid; the ferric salt is sodium iron; and the nettle liquid is obtained by decocting Stinging nettle and water in a ratio of 4:6 in a pot for 2-3 hours, cooling and filtering. The macroelements, trace elements and ferric salt are weighed according to 20 times and 200 times of the original volume and prepared into a concentrated solution. For each usage, each liter of water is added with 5ml of macroelements, 50ml of trace elements and 200 ml of nettle liquid, and the mixture is fully mixed into the nutrient liquid; and a pH is adjusted to 5-7. The nutrient solution can be used in floating seedling and floating cultivation of Chinese herbal medicine plant seed, and is particularly suitable for floating seedling and floating cultivation of seed of pseudo-ginseng and Paris polyphylla.

Description

Technical field: [0001] The invention relates to the field of liquid fertilizers, in particular to a nutrient solution component and a preparation method suitable for floating seedling raising and floating cultivation of Chinese herbal medicine plants, especially Sanqi and Chonglou. Background technique: [0002] Chinese herbal medicine plants, especially Panax notoginseng (Bruk) F.H.Chen and Chonglou are Paris polyphylla Smith var.yunnanensis (Franch.) Hand.Mazz. The main component of Baiyao. Due to the serious accumulation of soil salt and acidification caused by continuous cropping in the production of Chinese herbal medicine plants in recent years, nutrient imbalance and plant autotoxicity have led to the destruction of soil ecosystem, imbalance of soil nutrient ratio, weakened soil fertilizer supply performance, root rot, stem Rot and other diseases and insect pests are serious, affecting the output and quality of the above-mentioned Chinese herbal medicines, and restr...
