Embodiment Construction

[0035] Below in conjunction with embodiment the method of the present invention is further described.

[0036] A method for cultivating Flammulina velutipes with a water-retaining agent solidified nutrient solution as a medium, the specific implementation is as follows:

[0037] 1. Choose the agricultural water-retaining agent with a water absorption ratio of 200-300 times and a particle size of 80-100 mesh as the raw material.

[0038] 2. Preparation of nutrient solution for production:

[0039] (1) 10000ml nutrient solution consists of raw materials and ratio: 380 grams of sugar, 100 grams of flour, 40 grams of soybean powder, 50 grams of yeast extract, 40 grams of peptone, 20 grams of potassium dihydrogen phosphate, 10 grams of magnesium sulfate, water 9400ml;

[0040] (2) Preparation: Dilute the flour and soybean powder with 1000ml of cold water first, then heat 8400ml of water until the water temperature is 60-70°C, then add sugar, yeast extract, peptone, potassium dihy...

Abstract

The invention relates to the field of novel edible fungus cultivation technique, and in particular relates to a method for cultivating flammulina velutipes through taking a water-retaining agent solidified nutrient solution as a culture medium. The method comprises the concrete steps of: firstly preparing a nutrient solution rich and comprehensive in nutrition; completely absorbing and solidifying the nutrient solution into a granular solid nutrient solution by using an agricultural water-retaining agent of which the water absorption multiple is 200-300 times and the grain size is 80-100 meshes; preparing a fruiting culture medium through taking the solid nutrient solution as a main raw material; putting the solid culture matrix into a plastic bottle or a polypropylene dog-eared bag, carrying out conventional sterilization and inoculating with flammulina velutipes liquid strains; and cultivating the strains till fruiting through management. The method disclosed by the invention has the advantages that a lot of raw materials such as wood dust, cottonseed hull, corncob, bagasse and the like required in traditional production can be omitted; more than 200kg of materials can be replaced by only 1kg of the water-retaining agent; meantime, traditional process which is complex in working procedure, large in labour amount, long in production cycle and high in production cost is completely abandoned; and therefore, the method is worth popularizing.

Description

technical field [0001] The invention relates to the field of a new technology for cultivating edible fungi, in particular to a method for cultivating Flammulina velutipes by using a water-retaining agent to solidify a nutrient solution as a culture medium. technical background [0002] Flammulina velutipes is delicious, smooth and crisp, and extremely nutritious. According to determination, every hectogram of Flammulina velutipes dry product contains 13.49% of pure protein, almost surpassing all edible fungi. Flammulina velutipes contains 18 kinds of amino acids, among which 8 kinds of amino acids necessary for human body account for 44.5% of the total amount of amino acids, which is also higher than other mushrooms. In particular, lysine and arginine are particularly rich in content, and they are of great benefit to promoting children's physical and intellectual development, so the Japanese call it "enhancing wisdom mushroom". In addition, the proflavin contained in Flamm...
