Compound fungicide for enhancing wheat salt resistance and preparation method of compound fungicide

Abstract

The invention belongs to the field of microorganisms, and discloses a compound fungicide for enhancing wheat salt resistance and a preparation method of the compound fungicide. The compound fungicideis characterized in that microorganism compound bacteria comprise, by weight, 50-80 parts of azospirillum, 45-70 parts of pseudomonades, 20-40 parts of bacilli, 15-30 parts of streptomyces and 20-35 parts of yeast. The compound microorganism fungicide can improve salt stress applied onto plants, the salt resistance of wheat can be enhanced, soil property is improved, soil fertility is enhanced, sothat the wheat effectively absorbs nutrient substances, the yield of the wheat is improved, income of farmers is increased, the compound microorganism fungicide is environmentally friendly and effectively solves the problem of waste of saline and alkaline land resources, the compound microorganism fungicide acquired by a freeze drying technique is conveniently transported and has good popularization and application prospects, and transportation cost is saved.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to a compound bacterial agent for enhancing the salt tolerance of wheat and a preparation method thereof. Background technique [0002] With the growth of population and the development of social economy, the area of ​​cultivated land is gradually decreasing, and the quality of land is also declining. The problem of land salinization in the world is becoming more and more serious. Excessive soluble salts will affect the water absorption of the crops, making it difficult for the crops to absorb water, resulting in burnt seedlings. In addition, when the concentration of certain ions is too high, it will affect the absorption of other ions, thereby affecting the absorption of crop nutrients. At the same time, some ions have a direct toxic effect on crops, such as chloride ions may cause burns to crops, making it difficult for plants to survive on saline-alkali soil. Although...

Problems solved by technology

Excessive soluble salts will affect the water absorption of the crops, making it difficult for the crops to absorb water, resulting in burnt seedlings

In addition, when the concentration of certain ions is too high, it will affect the absorption of other ions, thereby affecting the absorption of crop nutrients.

At the same time, some ions have a direct toxic effect on crops, such as chloride ions may cause burns to crops, making it difficult for plants to survive on saline-alkali soil

Although saline-alkali land is an available resource, due to the low soil fertility and poor physical and chemical properties of saline-alkali land, there are many anions and cations harmful to crops, the crop yield is low, and the economic benefit is low, so this land resource is still largely wasted.
