Embodiment 1

[0026] The biological preparation prepared in the third step is an aqueous emulsion, and its preparation process: take 1-9% of fermentation broth, 3-10% of solvent, 5-15% of emulsifier, 5-10% of dispersant, antifreeze 1- 5%, defoamer 0.05-0.3%, PH regulator 1-2%, deionized water 50%-85%, mix and dissolve the fermentation broth, solvent, and emulsifier into a uniform oil phase, disperse, antifreeze , Defoamer and deionized water are mixed to form a uniform water phase. Under high-speed stirring, add the water phase to the oil phase and add the pH regulator to obtain a well-dispersed chamaejasme water emulsion.

[0027] The water emulsion is sprayed on wheat to prevent and control wheat head blight, and the effect is remarkable.

Embodiment 2

[0029] The biological preparation prepared in the third step is a suspending agent, and its preparation process: take 1-10% of fermentation broth, 5-10% of dispersant, 2-5% of suspension stabilizer, 1-5% of antifreeze, defoaming Adding agent 0.05-0.3%, pH regulator 1-2%, deionized water 50%-85%, put the above materials into the mixing pulping machine for pre-mixing, and then pump into the first sand mill, second sand mill, The homomixer pulverizes and homogenizes to obtain the chamaejasme suspension.

[0030] The suspending agent is sprayed on apple trees to prevent and control apple anthracnose, and the effect is remarkable.

Embodiment 3

[0032] The biological preparation prepared in the third step is a microemulsion, and its preparation process: take 1-9% of fermentation broth, 3-10% of solvent, 5-15% of emulsifier, 3-5% of cosolvent, 1-5% of antifreeze 5%, stabilizer 3-5%, deionized water 50%-80%, mix the emulsifier and deionized water to form a uniform water phase, stir the fermentation broth, solvent, antifreeze, cosolvent, and stabilizer at high speed Add the water phase in the state to prepare a chamaejasme microemulsion.

[0033] Spraying the microemulsion on rice is used to control rice sheath blight, and the effect is remarkable.

Abstract

The invention discloses a method for preparing a biological agent by radix euphorbiae ebracteolatae. The method comprises the following steps: washing off sundries on the skin of the collected radix euphorbiae ebracteolatae, and naturally airing for 2-3 days at the temperature of 15-25 DEG C; smashing processed raw materials in the first step, putting the smashed raw materials in a fermentation chamber, slowly adding sweet water and stirring until the ratio of material to liquid is 1:(0.8-1), then adding zygosaccharomyces bailii and acetobacter xylinum being 0.1-0.5% of the material and liquid total quantity, wherein the mixing ratio of the zygosaccharomyces bailii to the acetobacter xylinum is 1:(0.8-1), and fermenting for 3-6 days at a constant temperature; taking fermentation liquid on the upper layer in the second step, and after filtering and removing particles in the fermentation liquid, combining the fermentation liquid, auxiliaries and water in proportions to prepare the biological agent. The zygosaccharomyces bailii and the acetobacter xylinum are used for fermenting the radix euphorbiae ebracteolatae, so that radix euphorbiae ebracteolatae ponicidin is greatly analyzed, and meanwhile the toxicity of radix euphorbiae ebracteolatae is eliminated; the prepared biological agent has remarkable effects on disease control of wheat, rice, apples and cucumbers, and is free of pesticide residues.

Description

Technical field [0001] The invention relates to a method for preparing biological preparations by using chamaejasme, belonging to the technical field of biological preparations. Background technique [0002] Euphorbia chamaejasme is the root of Euphorbia euphorbia. It is a perennial herb with a height of 30-60 cm. The root is thick, fleshy, spindle-shaped to conical, with yellowish brown skin, yellow latex, green stem, purple base, alternate leaves , The leaf blade is oblong-lanceolate, 4-11cm long, 1-2.5cm wide, whole. The total inflorescence is multi-cymose-shaped and grows at the terminal. 5 umbral stalks are umbrella-shaped, each stalk gives birth to 3 small stalks or a third small stalk; the cup-shaped cyme is broadly bell-shaped, and the total cup lobes apex Irregularly lobed; glands half moon-shaped, capsules triangular-shaped oblate, glabrous, seeds round ovoid, brown, flowering from April to June, fruiting from May to July, born on hillside, grassland or under forest, ...
