Embodiment 1

[0026] Embodiment 1: a kind of special microbial fertilizer for rice improved in saline-alkali land

[0027] A special microbial fertilizer for rice improved in saline-alkaline land comprises the following components in mass percentage: 75% of microbial bacterial agent, 12% of elemental nutrient, 8% of carbon nanotube, and 5% of 1-methylcyclopropene.

[0028] The microbial inoculant is obtained through the following steps:

[0029] 1) Dilute the concentrated distiller's grain waste liquid purchased from Qiandaohu Brewery 100 times with water, adjust the pH value to 7.5, sterilize, cool, and use it as a culture medium;

[0030] 2) Inoculate the mixed bacterial solution according to the inoculum volume of 15% of the culture solution volume, and the mixed bacterial solution is composed of Pseudomonas fluorescens, Bradygonia halotolerant, Interrhizobia xylobia and Lactobacillus in a mass ratio of 1:1: 1:1 mixed to get;

[0031] 3) Ferment and cultivate for 48 hours at a temperat...

Abstract

Microbial fertilizer specially used for rice and for improvement of saline alkali land belongs to the technical field of fertilizer. The fertilizer includes, by mass, the following components: 70%-80%of a microbial agent, 8%-20% of an elemental nutritional agent, 2%-10% of carbon nanotubes, and 2%-6% of 1-methylcyclopropene; and the microbial agent is obtained from fermentation of pseudomonas fluorescens, salt-tolerant Bacillus lentus, Rhizopus intermedia and lactobacillus. The microbial fertilizer specially used for the rice and for the improvement of the saline alkali land is reasonable indesign, and through intervention of exogenous functional microorganisms on a rhizosphere micro-domain of rice, the method can make the usage amount of fertilizer reduce, the improvement effect of thesaline alkali land is improved, and the salt tolerance of the rice is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special microbial fertilizer for rice improved in saline-alkali land. Background technique [0002] my country's saline-alkali cultivated land area is 7.6 million hectares, of which about 6.6 million hectares are saline soil and 1 million hectares are alkaline soil. The saline-alkali soil in East China, South China and coastal areas with large rice planting area accounts for about 15% of the national saline-alkali soil, the groundwater salinity is greater than 10g / L (up to 50g / L), and the salt content is generally above 0.4% , the main salt is Cl - , which has become the main limiting factor for the increase of local rice production. Rice is the most sensitive response to salt stress among cereal crops. The salinity threshold is 3dS / m, and the yield decreases by 12% for every 1dS / m increase beyond the threshold. Osmotic stress, oxidative stress, and ion stres...
