Embodiment 1

[0030] Grind the corn stalks to 20 mesh with a pulverizer. The collected feces of livestock and poultry such as pigs and chickens are piled up, covered with 1.5cm of mud on the surface, piled up and fermented for 30 days. Then dry, crush and set aside.

[0031] Preparation of nitrogen-fixing bacterial agent: 45 parts of corn stalks, 55 parts of bran, moistened with water, material: water=1:2.8, sterilized, connected with 6 parts of Nocardia cellulosus HD-86 secondary strain. Fermented at 30°C for 3 days under sterile conditions, with a relative air humidity of 84%, dried at a low temperature of 70°C, and pulverized; the above are parts by weight, the same below.

[0032] Preparation of Trichoderma inoculum: 45 parts of corncobs, 55 parts of bran, and 1.5 parts of ammonium sulfate are used as culture medium, the raw materials are pulverized and mixed, moistened with water, material: water=1:2.8, sterilized, and connected with Trichoderma pseudokonii 6 copies of S28 secondary ...

Embodiment 3

[0040] B. Secondary bacterial strains: the formula of the culture medium is the same as that of the slant, only agar is not added, the natural pH value is bottled, sterilized at 8 pounds, the bacterial suspension of the slant strain is 4% by weight, cultured on a shaking table at 28°C . Embodiment 2. as described in embodiment 1, difference is: replace corn stalk with 100 parts of wheat straw raw materials. Embodiment 3. As described in embodiment 1, the difference is:

[0041] Preparation of nitrogen-fixing bacterial agent: 50 parts of corn stalks, 60 parts of bran, moistened with water, material: water=1:3.0, sterilized, and connected with 7 parts of Nocardia cellulosus HD-86 secondary strain.

[0042] Preparation of Trichoderma inoculum: 50 parts of corncobs, 60 parts of bran, and 2 parts of ammonium sulfate are used as culture medium, the raw materials are pulverized and mixed, moistened with water, material: water=1:3.0, sterilized, and then connected with Trichoderma ps...

Abstract

The preparation method of organic ecological soilless culture medium belongs to the field of agricultural bio technology. It is made up by using 100 portions of straw powder, 50-60 portions of cumulose fermented livestock and fowl dried excrements and 3-5 portions of compound bacterial preparation formed from azotogen and trichoderma preparation through the processes of uniformly mixing and stirring. The preparation of azotogen adopts cellulose Nocardia HD-86 with functions of decomposing cellulose and fixing nitrogen as strain and adds the corn stover, bran and water, and utilizes the aseptic fermentation process to obtain the azotogen, and the preparation of trichoderma preparation uses pseudo-Kan's trichodermin S28 as strain, and uses cob, bran, ammonium sulfate as culture medium through the processes of pulverizing, mixing, moistening, inoculating S28 and fermentation so as to obtain the trichoderma preparation. Said invention is favorable for industrial production of vegetables.

Description

(1) Technical field [0001] The invention relates to a preparation method of an organic ecological soilless cultivation medium, which belongs to the field of agricultural biotechnology. (2) Background technology [0002] The total amount of crop straw in the country is 650 million tons, of which about 20% are directly returned to the field, about 25% are used as feed "returning to the field", about 30% are used in rural life, and the straw used as industrial raw materials is insufficient 5%, more than 20% of the total straw is the remaining amount. In recent years, during the "double rush" seasons of summer and autumn harvests, straw burning has generally occurred, and there has been a phenomenon of igniting fires in every village and smoking everywhere. Not only wasting precious resources, but also polluting the environment, accidents continue every year, and even affect traffic and flights. The recycling of straw has become a major problem of "a headache for the governmen...
