Embodiment 1

[0025] Embodiment 1, with 100ml white rot fungus spore suspension (10 5 cfu / ml) is diluted with 40 kg of sterilized basal medium and mixed with 50 kg of wood chips sterilized by high-temperature steam to make the water content of the wood chips 50%. Pack one bag per 2kg, culture in a 37°C incubator for 9 days, dry in a 40°C oven for 20 hours, and set aside. Two weeks before sowing, apply white rot fungicide at 400g / m 2 The amount of land is applied to the soil surface at a depth of 10cm, the soil is loosened, and watered to keep it moist.

Embodiment 2

[0026] Embodiment 2, with 200ml white rot fungus spore suspension (10 6 cfu / ml) was diluted with 70 kg of sterilized basal medium and mixed with 80 kg of wood chips sterilized by high-temperature steam to make the water content of the wood chips 50%. Pack one bag per 2kg, culture in a 30°C incubator for 10 days, dry in a 45°C oven for 22 hours, and set aside. Two weeks before sowing, apply white rot fungicide at 500g / m 2 The amount of land is applied to the soil surface at a depth of 20cm, loosened, and watered to keep it moist.

Embodiment 3

[0027] Embodiment 3, with 100ml white rot fungus spore suspension (10 5 cfu / ml) was diluted with 75kg of sterilized basal medium and mixed with 60kg of wood chips sterilized by high-temperature steam to make the water content of the wood chips 60%. Pack one bag per 2kg, culture in a 35°C incubator for 8 days, dry in a 50°C oven for 24 hours, and set aside. Two weeks before sowing, apply white rot fungicide at 450g / m 2 The amount of land is applied to the soil surface at a depth of 30cm, loosened, and watered to keep it moist.

Abstract

The application of whterot fungus preparation in improving the continuous cropping performance of soil belongs to the field of microbe applying technology. Its implementation includes the following steps: applying whterot fungus preparation in the amount of 400-500 g / sq m into soil in the depth of 10-30 cm in two weeks before seeding, loosening soil, watering and maintaining moisture. The present invention can improve the continuous cropping performance of soil, promote the amplification of beneficial flora, preventing and controlling diseases and pests of crop, and raise the yield and quality of crop.

Description

technical field [0001] The invention belongs to the technical field of microorganism application, and relates to a method for treating soil by using microorganisms, in particular to the application of a white-rot fungal agent in improving soil continuous cropping obstacles. Background technique [0002] The obstacle of continuous cropping is that when the same crop or related crops are continuously planted on the same soil, the normal cultivation and management measures will result in reduced yield, poor quality, and poor growth status. Many horticultural plants (including fruits and vegetables and ornamental flowers), field economic crops and Chinese herbal medicines have varying degrees of continuous cropping obstacles. Although people have recognized this problem in agricultural production for a long time, they have avoided or alleviated the occurrence of this phenomenon by adopting crop rotation and stubble farming. However, due to the limited arable land, the drive of ...
