[0175] (2.1.2) Preparation of drug-containing medium
[0176] Dissolve the original powder of the drug with methanol + 0.1% TWEEN-80, and dilute it with sterile distilled water to make a 10g / L mother solution. Cool down to about 50°C after sterilizing, add 1mL of prepared medicines to 9mL medium and shake well to obtain medicine-containing medium containing medicines of various concentrations, add the same amount of sterile water as a control, each treatment Set up 3 repetitions;
[0177] (2.1.3) Toxicity determination
[0178] The mycelium growth rate method was used to measure. Put the pre-cultivated colonies of the tested strains on the ultra-clean workbench, use a puncher with a diameter of 5mm to punch out the bacteria disc along the same circumference of the edge of the colony, and then paste the side of the bacteria disc containing the hyphae on the side containing the drug. In the center of the culture medium, place it upside down in a constant temperature incubator...
Embodiment 1
[0280] The preparation of embodiment 1 suspension seed coating
[0281] 0.6% tebuconazole, 9% cyantraniliprole, 9% thiamethoxam, 1% borax, 0.5% zinc sulfate, 0.5% molybdate molybdate, 0.0026mg / L brassinolide, 1.5% sodium alginate , 3% NNO, 1% Tween 80, 1% Acid Scarlet and 72.9% water were put into an electromagnetic stirrer and mixed uniformly, and the mixture was placed in a high-speed emulsifying shearing machine to be sheared and emulsified to obtain a finished product.
Embodiment 2
[0282] The preparation method of embodiment 2 coated sorghum seeds
[0283] Place 500 g of selected sorghum seeds in a sterile dry wide-mouth conical flask, pour 10 mL of the suspension seed coating agent prepared in Example 1 into it, shake it by hand, shake it in a shaker for 10 minutes, and place Blow dry in a ventilated place.

Abstract
The invention discloses a research method of a pesticide-fertilizer composite seed coating agent for sorghum, belonging to the field of pesticide-fertilizers for sorghum. The method specifically comprises the following steps: S1, screening a formula for a seed coating pesticide: S1.1, screening proper bactericides and insecticides according to sorghum head smut and main soil insects by using methods of indoor toxicity measurement, seed safety test and the like, and determining the optimal dosages of the bactericides and insecticides; and S1.2, according to growth rules of sorghum, screening out an appropriate growth regulator by using an indoor seed germination method, and determining the optimal dosage of the growth regulator; S2, screening a formula for a seed coating agent micro-elementfertilizer; S3, screening a formula for a seed coating agent auxiliary agent; S4, detecting technical indexes of the seed coating agent; and S5, evaluating the biological effect of the seed coating agent. The sorghum seed coating agent which can promote seed germination and seedling growth, prevent and control seed propagation and main diseases and insect pests in a seedling stage and reduce theapplication amount of chemical fertilizers and pesticides is developed in virtue of the research method.
Description
technical field [0001] The invention relates to the technical field of sorghum medicinal fertilizer, in particular to a research method of a compound seed coating agent of sorghum medicinal fertilizer. Background technique [0002] Seed coating agent is developed from traditional seed soaking and seed dressing. It is processed by using modern technical equipment to process pesticides, chemical fertilizers, plant growth regulators, film-forming agents and other auxiliaries, and is coated on the surface of plant seeds. Its standardized and commercialized special drug dosage form (Zhao Leilei et al., 2009). Studies have shown that the use of seed coating agent to coat the seeds can significantly increase the yield of crops and prevent the occurrence of pests and diseases (Song Juming et al., 1989). Seed coating agent is a special pesticide formulation because it has better protection. , systemic conduction and sustained release have attracted much attention (Mu Kangguo et al.,...
