Embodiment 1

[0049] Embodiment 1, improving secondary salinization greenhouse soil (alkaline greenhouse soil)

[0050] 1. Preparation of Paenibacillus jamiri inoculum

[0051] The preparation method of the culture medium used in this embodiment is as follows:

[0052] Beef extract medium: glucose 20g, peptone 15g, sodium chloride 5g, beef extract 0.5g, agar 20g, distilled water to 1L, pH 7.0, sterilized at 121°C for 15min.

[0053] Fermentation medium of Paenibacillus: sucrose 15g, soybean meal 10g, (NH 4 ) 2 SO 4 4g,K 2 HPO 4 0.5g, MgSO 4 ·7H 2 O 0.1g, distilled water to 1L, pH 6.5, sterilized at 121°C for 15min.

[0054] Inoculate Paenibacillus jamilae (Paenibacillus jamilae) ACCC 03134 on a beef extract culture plate, culture at 37°C for 72 hours, then scrape off the spores on a culture plate and insert it into 500 mL of fermentation medium containing 200 mL of Paenibacillus jamilae In a triangular flask, cultivate for 72h at 37°C and 220rpm; then inoculate 2% (v / v) inoculum ...

Abstract

The invention discloses a fertilization method for improving secondary salinized greenhouse soil. The fertilization method includes applying organic fertilizer and inoculum to the secondary salinized greenhouse soil to be improved, so that the secondary salinized greenhouse soil to be improved is improved, and the active component of the inoculum is Paenibacillus. Adding organic fertilizer as base fertilizer and then applying Paenibacillus mili bacteria agent can improve the secondary salinized soil to neutral soil, improve the EC value and organic matter content of the secondary salinized soil, and increase the yield of cucumber. The invention can be used to improve the secondary salinized soil and increase the yield of cucumber.

Description

technical field [0001] The invention relates to a fertilization method for improving secondary salinized greenhouse soil. Background technique [0002] Secondary salinization (secondary salinization), also known as "soil secondary salinization", is the process of cultivated soil salinization caused by unreasonable human measures. [0003] The formation and degree of soil secondary salinization are closely related to the facility environment and human farming management. Facility cultivation is a long-term closed cultivation mode, which causes the temperature inside the facility to be higher than the outside all the year round, and does not receive sufficient leaching from natural rainwater and freezing and thawing of the soil in winter and spring. In addition, frequent watering is used to adjust the ground temperature of oversummer cultivation. The temperature makes the transpiration and evaporation of soil moisture stronger than that of the open field. According to the la...
