Embodiment 1

[0105] Embodiment one: a kind of preparation method of the soil conditioner of preventing and treating wheat take-all in newly reclamation farmland is, and this method comprises the steps:

[0106] a. Preparation of Trichoderma preparation: Activate the Trichoderma harzianum strains preserved in inclined test tubes with PDA medium, then inoculate them on PDA plates and place them in an incubator at 25°C for expanded culture for about 3 days to obtain expanded culture of Trichoderma harzianum Inoculate the expanded cultured Trichoderma strains into PDA culture medium and place them in a shaker for 3 to 5 days, then inoculate them in solid cultures sterilized at 121°C, and ferment with aeration at 24°C to 26°C for 7 After ~10 days, the solid fermented product is obtained, which is then dried in the sun, added with diatomite with a weight content of 15-20%, and rice husks with a weight content of 5-10%, and then pulverized, and passed through an 80-mesh sieve to obtain wood mold ...

Embodiment 2

[0109] Embodiment two: a kind of preparation method of the soil conditioner of newly reclamation farmland prevention and treatment of wheat take-all is, and the method comprises the steps:

[0110] a. Preparation of Trichoderma preparation: Activate the Trichoderma harzianum strains preserved in inclined test tubes with PDA medium, then inoculate them on PDA plates and place them in an incubator at 25°C for expanded culture for about 3 days to obtain expanded culture of Trichoderma harzianum Inoculate the expanded cultured Trichoderma strains into PDA culture medium and place them in a shaker for 3 to 5 days, then inoculate them in solid cultures sterilized at 121°C, and ferment with aeration at 24°C to 26°C for 7 After ~10 days, the solid fermented product is obtained, which is then dried in the sun, added with diatomite with a weight content of 15-20%, and rice husks with a weight content of 5-10%, and then pulverized, and passed through an 80-mesh sieve to obtain wood mold ...

Embodiment 3

[0113] Embodiment three: a kind of preparation method of the soil conditioner of newly reclamation farmland prevention and treatment of wheat take-all disease is, and this method comprises the steps:

Abstract

The invention relates to a soil conditioner, in particular to a soil conditioner for preventing and curing wheat take-all in newly cultivated farmland. The soil conditioner is prepared from the following raw materials by weight percent: 20 to 27% of sheep manure, 20 to 27% of fulvic acid potassium, 20 to 30% of Kang Dibao, 0.5 to 1.5% of manganese sulfate, 1 to 2% of zinc sulfate, 10 to 15% of trichoderma preparations, 0.5 to 1.5% of fly maggot powder and 10 to 15% of rejects. The preparation method of the soil conditioner comprises the following steps of: preparing, drying and crushing the trichoderma preparations, respectively crushing the sheep manure, the Kang Dibao, the fulvic acid potassium, the manganese sulfate, the zinc sulfate, the fly maggot powder and the rejects, then mixing all components of the soil conditioner in the dry state, and fully stirring and uniformly mixing the components to obtain beige powdery product which is the soil conditioner. The soil conditioner is applied after being uniformly mixed with chemical fertilizers before crop sowing or is sowed together with seeds when the crop is sowed. The invention provides the soil conditioner capable of conditioning the structure of soil, enhancing the fertility of the soil, enhancing the disease-resistant capacity of the crop and reducing the generation of the wheat take-all.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a soil conditioner for preventing and controlling wheat take-all in newly reclaimed farmland and its preparation method and application method. Background technique [0002] Wheat take-all is called "cancer" among plant diseases, and it is a worldwide disease. Its occurrence has been recorded for more than 100 years and it is distributed in more than 100 countries or regions. The area of ​​wheat take-all in my country is about 20 million mu every year. Wheat take-all disease was first discovered in Xiji County in Ningxia in 1974, and then it spread rapidly, the damage continued to increase, and the yield loss also continued to increase. Not only that, at present, with the construction and expansion of the Yellow River Yang Project in Ningxia Hui Autonomous Region, the area of ​​newly cultivated farmland in Hongsibao, Yanchi County, Huinong District, Pingluo County and other places has rapid...
