The invention provides a processing method for controlling microbes of dehydrated spices through combining irradiation of high-energy electron beams with hot-air drying, and belongs to the technical field of deep processing of farm products. The processing method comprises the following processes that: fresh spices are subjected to selection, cleaning and water draining; high-energy electron beam irradiation is carried out; and phased atmospheric pressure hot-air drying is carried out after the irradiation. The processing method has the advantages that the irradiation of the high-energy electron beams on the fresh spices has the effects that: 1, partial microbes in raw materials can be directly killed, and the number of the microbes is reduced; and 2, through the penetration effect of the high-energy electron beams, cell structures in the fresh spices can deform, shrink or crack and the like, so tissue fluid in cells is easier to exude or lose, and the free water content is increased; and the water is favorably diffused out during the drying, and the drying efficiency is improved. The phased hot-air drying has the effects that: 1, the water in the raw materials is evaporated to obtain dried products; and 2, through the irradiation effect on the microbes, the physiological functions of the microbes in the spices are damaged to different degrees and cannot be restored during the drying; the microbes in the spices can be effectively killed with a low dose of irradiation; and the hot-air drying efficiency is improved.

The invention relates to organic concentrated nutrient solution special for flower and potted landscapes and a preparation method thereof. The preparation method mainly comprises the following steps of: (1) uniformly mixing milk, soybean milk, common salt and a fermentation agent according to a weight ratio of 10-30:10-40:1-3:1-5 and then placing in a fermentation tank, and fermenting at normal temperature for 20-40 days to obtain fermentation broth A; (2) uniformly mixing animal dung, water and the fermentation agent according to a weight ratio of 30-40:10-20:1-5 and then placing in the fermentation tank, fermenting at the normal temperature for 30-60 days and discarding residue to obtain fermentation broth B; and (3) mixing the fermentation broth A and the fermentation broth B according to a weight ratio of 1:0.8-1 and filling. The preparation method of the organic concentrated nutrient solution is simple; the raw materials are low in cost and readily available; a product is natural, organic, safe and pollution-free; peculiar smell is not produced after application; the nutrient content is high and the nutrition is complete; and the organic concentrated nutrient solution has high pertinence to nutritional requirement of potted plants.
