Embodiment 1

[0017] Prepare nutrient solution, each 1000mL nutrient solution contains: 10g of sucrose, 5.0mg of ferrous sulfate heptahydrate, 11mg of boric acid, 90mg of ammonium chloride, 7.5mg of copper sulfate, 22mg of manganese sulfate, 12mg of zinc sulfate, and 30mL of Armillaria fermentation broth.

[0018] First prepare ferrous sulfate heptahydrate, boric acid, ammonium chloride, copper sulfate, manganese sulfate, and zinc sulfate to make 100 times mother liquor (keep it in the refrigerator for later use). When preparing the nutrient solution, mix the mother liquor and water at a ratio of 1:100, then add sugar and Armillaria fermentation broth according to the formula, and make up with water to obtain the nutrient solution.

[0019] The preparation process of Armillaria mellea fermentation liquid is: take Armillaria mellea (Vahl.ex Fr.) Quel. parent species, transfer in the sterilized culture liquid, shake and cultivate at 110rpm on a shaker, and the culture temperature is 25 After ...

Embodiment 2

[0025] Prepare nutrient solution, each 1000mL nutrient solution contains: 15g of glucose, 5.5mg of ferrous sulfate heptahydrate, 13mg of boric acid, 100mg of ammonium chloride, 8.2mg of copper sulfate, 25mg of manganese sulfate, 15mg of zinc sulfate, 50mL of Armillaria fermented liquid, prepared Method is with embodiment 1.

[0026] Application test:

[0027] In the first ten days of April in Beijing greenhouse, plant red gastrodia strogaea, and the selection is the same as in Example 1.

[0028] The control group used pure water, and the test group used nutrient solution to irrigate the tubers of Gastrodia elata; the amount of nutrient solution or pure water was 50 mL per 200 g of fresh weight of arrowroot, and watered until the gastrodia elata fruit matured; once every 7 days.

[0029] The results showed that: compared with the control treatment, the Gastrodia elata fruit in the test group was plump, the average fruit weight increased by 20.7%, the seed quality increased, t...

Embodiment 3

[0031] Prepare nutrient solution, each 1000mL nutrient solution contains: glucose 12g, ferrous sulfate heptahydrate 5.3mg, boric acid 12mg, ammonium chloride 95mg, copper sulfate 7.85mg, manganese sulfate 22.5mg, zinc sulfate 12.5mg, armillaria fermented broth 40mL , preparation method is the same as embodiment 1.

[0032] Application test:

[0033] In the first ten days of April in Beijing greenhouse, plant red gastrodia strogaea, and the selection is the same as in Example 1. The control group used pure water, and the test group used nutrient solution to irrigate the tubers of Gastrodia elata; the amount of nutrient solution or pure water per 200g of fresh weight of arrowroot was 40mL, and watered until the Gastrodia elata fruit matured; once every 5 days.

[0034] The results showed that compared with the control treatment, the Gastrodia elata fruit in the test group was plump, the average weight of the fruit increased by 22.2%, the quality of the seeds increased, the leng...

Abstract

The invention relates to a nutrient solution capable of improving seed quality of rhizoma Gastrodiae. Each 1000 mL of the nutrient solution contains 10 to 15 g of sugar, 5.0 to 5.5 mg of ferrous sulfate heptahydrate, 11 to 13 mg of boric acid, 90 to 100 mg of ammonium chloride, 7.5 to 8.2 mg of copper sulphate, 22 to 25 mg of manganese sulfate, 12 to 15 mg of zinc sulfate and 30 to 50 ml of armillaria mellea fermentation broth. The nutrient solution can substantially improve the fruit setting rate and quality of seeds of rhizoma Gastrodiae, provides an excellent seed source for stable high yielding of sexual reproduction and improves economic benefits of production of rhizoma Gastrodiae.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a nutrient solution for improving the quality of plant seeds. Background technique [0002] Gastrodia elata Blume (Gastrodia elata Blume) is a precious medicinal material in my country with high medicinal value. The domestic and foreign markets are in short supply. The development of Gastrodia elata production has good economic benefits and a stable and reliable prospect. Gastrodia elata belongs to the Orchidaceae plant, which cannot carry out photosynthesis and cannot complete the life cycle independently, so the cultivation method of Gastrodia elata is different from that of ordinary green plants. Gastrodia elata artificial cultivation has two kinds of asexual reproduction and sexual reproduction. Asexual reproduction uses Gastrodia elata tubers (dried tubers are Gastrodia elata medicinal materials) as propagation materials, and its growth cycle is short, but long-te...
