The invention relates to the technical field of organic fertilizers and planting of watermelons and muskmelons, and provides a special fertilizer for milk irrigated watermelons and muskmelons and a double-stubble planting method for sweetness enhancement of milk irrigated watermelons and muskmelons. The special fertilizer for the milk irrigated watermelons and muskmelons comprises black goat manure, sophora alopecuroide, sesame seed meal, bran, organic fresh milk, brown sugar and zymophyte. The black goat manure is pulverized into powder by a pulverizer, the sophora alopecuroide is pulverizedinto 1 cm to 2 cm, and the ratio of the black goat manure, the sophora alopecuroide, the sesame seed meal, the brans, the organic fresh milk, the brown sugar and the zymophyte is 2700-3200: 80: 50: 150: 5: 1. The double-stubble planting method for sweetness enhancement of the milk irrigated watermelons and muskmelons comprises the following steps: selection of a nursery seedling plate and soil, cleaning and germination accelerating of seeds, soil preparation, transplanting, irrigation, topdressing, shaping and forking of watermelon and muskmelon vines and fruit bearing of the watermelons and the muskmelons. The problems that in an existing watermelon and muskmelon planting process, soil nutrients are damaged due to the fact that chemical fertilizers are used for a long time, and the sweetness of melons is reduced are solved.

The invention provides bacillus licheniformis capable of producing amylase, protease and cellulase and application of the bacillus licheniformis. The bacillus licheniformis is bacillus licheniformis FJAT-27214 and is preserved in the China General Microbiological Culture Collection Center on August 6, 2025, the preservation address is No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing, and the preservation number is CGMCC No. 35536. The bacillus licheniformis disclosed by the invention can be used for simultaneously producing amylase, protease and cellulase at high yield; the bacillus subtilis has antibacterial activity to escherichia coli and has certain tolerance to artificial gastric juice, artificial intestinal juice and cholate, the survival rate in the artificial gastric juice is 58.11%, the survival rate in the artificial intestinal juice is 82.58%, and the survival rate in the cholate is 28.03%. When the strain fermentation liquor is used for pomace micro-storage, the content of crude protein and total sugar of pomace can be remarkably increased, meanwhile, the content of neutral detergent fiber and ammoniacal nitrogen is remarkably reduced, and an effective strain resource is provided for pomace micro-storage fermented feed.

The invention belongs to the technical field of compound fertilizers, and particularly relates to a compound fertilizer microbial fertilizer as well as a preparation method and application thereof. The preparation method of the compound microbial fertilizer comprises the following steps: respectively fermenting livestock slaughtering wastes, livestock wastes, waste melons and fruits and eggshells to obtain a solution a, a solution b, a solution c and a solution d; mixing the obtained solutions in proportion, adding molasses, bacillus subtilis, EM bacteria and trichoderma harzianum, fully mixing, and carrying out secondary fermentation to obtain a compound microorganism stock solution; and adding the nitrogen-phosphorus-potassium inorganic fertilizer and the compound microorganism stock solution, and fully stirring to obtain the fertilizer. The invention discloses a compound microbial fertilizer prepared by a preparation method, which is used for solving the problems of soil hardening, acidification and plant diseases and insect pests caused by chemical fertilizer application, soil quality improvement, harmful substance reduction and fertility improvement.

This utility model discloses an artificial light source device suitable for strawberry cultivation in plant factories, including a lamp housing, an aluminum substrate, and a control panel. A light source module is fixedly connected to the surface of the aluminum substrate. The light source module includes four independent light source channels divided by wavelength: a first light source channel emitting 660nm red light, a second light source channel emitting 450nm blue light, a third light source channel emitting 730nm far-red light, and a fourth light source channel emitting 590nm yellow light. The LEDs are all COB LED packages and are welded to the aluminum substrate according to a uniform distribution and symmetrical arrangement. A driving circuit module corresponding to each light source module is fixedly connected to the other side wall of the aluminum substrate. This utility model can increase the sugar content of strawberry fruits and reduce the rate of deformed fruits, solving the problem of traditional general-purpose light sources having a single spectrum and being unable to adapt to the needs of different strawberry growth stages. Compared with traditional light sources that are manually adjusted, it can reduce manual maintenance time and lower the operating costs for growers.
