The invention discloses a method and device for preparing ceramsite from sludge pyrolytic biochar. The method includes the steps that powder grinding, humidifying, pelleting, low-temperature drying, middle-temperature presintering, high-temperature sintering and cooling are carried out on the sludge pyrolytic biochar to obtain the ceramsite. The device comprises a quantitative feeding device, a water adding device, a humidifying device, a forming and pelleting device, a drying device, a middle-temperature presintering device, a high-temperature sintering device and a cooling device. The sludge pyrolytic biochar is used for preparing the ceramsite, large-scale utilization of the sludge pyrolytic biochar is achieved, heavy metal element in the sludge pyrolytic biochar is further efficiently solidified and passivated, potential heavy metal accumulated pollution of the sludge pyrolytic biochar in the land using process is avoided, and the method and device are particularly suitable for resource utilization of sludge pyrolytic biochar with heavy metal content exceeding standard. The method is simple, practical, low in equipment investment and low in cost and has good economic benefits and environmental benefits.

The invention provides an effective method for improving the quality of ranunculus hybrid seeds, which specifically includes the following steps: (1) planting of parent materials: soaking seeds in warm water, placing them in a refrigerator at 0-4°C for 5-7 days, and accelerating germination at room temperature for 7-7 days 10 days, sow in non-woven nutrient bags, and the parents are planted according to 1:1-1.2 moisture separation, and 1200 plants are planted per mu; (2) Ground cover: full-covered with black polyethylene film with a light transmittance of less than 10%; (3 ) Greenhouse warming: control the temperature in the greenhouse to 15-20°C; (4) Supplementary light for male parents: use LED light strips for 24h supplementary light every day, and the light intensity is 2000-3000Lx; (5) Cross-pollination: after emasculation Start pollination in 3 days, and pollinate 3 times; (6) harvest seeds. The present invention greatly improves the pollen yield and pollen vigor of the ranunculus male plant through methods such as seed soaking, full film-covering cultivation, and male parent light supplementation, combined with reasonable temperature control, and further significantly improves the hybrid seed setting rate of ranunculus, the highest possible up to 94.5%.

The invention discloses a special weeding film for fruit trees and a preparation process of the special weeding film. The special weeding film is prepared from the following components in percentage by mass: 65-80% of linear low-density polyethylene, 4-10% of low-density polyethylene, 6-10% of anti-aging masterbatch and 10-15% of light-blocking black masterbatch, wherein the anti-aging masterbatch is formed by reasonably matching, mixing and granulating according to demands. According to the preparation process disclosed by the invention, a conventional ground film blowing unit is adopted, PLC terminal software is adopted for inputting signals, particles which are well matched and mixed are put into a feed inlet of an extruder by a mechanical hand, and screw conveying, homogenization, compression, filtration, molding, traction, air ring cooling, coiling and packaging are performed; and the compression ratio of a mold head is controlled at 4.0-4.5 in molding, and the blow-up ratio of the film is controlled at 3.0-3.5. Compared with general molding requirements, the mechanical strength of the film is improved in comparison with that of the ordinary weeding ground film. According to the preparation process disclosed by the invention, the problems that a small amount of additives is added in the traditional process and the mixing with main raw materials is non-uniform to cause that the product quality is affected are solved, the stability of the product quality is ensured, the frequency of adding the materials is reduced, the time is saved and the product performances are further improved.

The invention discloses a method for preparing a culture medium with Chinese herbal medicine dregs. The method comprises the steps as follows: after the Chinese herbal medicine dregs are accumulated for anaerobic fermentation, compound bacteria of bacillus subtilis and aspergillus niger as per the bacterial content are added and mixed uniformly to enable the bacterial content concentration to be higher than 500 thousands bacteria per gram, then syrup is sprayed and mixed uniformly, after accumulation, the accumulated materials are covered with a black plastic film until the highest temperature in the accumulated materials reaches 55 DEG C, the black plastic film is removed for aerobic fermentation until the moisture content of the accumulated materials is lower than 45%, and the culture medium can be obtained through accumulation and ageing. The culture medium prepared with the method is low in salinity, low in EC value, large in cation exchange capacity and high in acid-base buffering capacity and saline-alkaline buffering capacity; meanwhile, by the aid of the culture medium, the soil looseness degree, the fertilizer keeping and water holding capacity and the heat insulation and ventilation capacity can also be improved; the culture medium is suitable for most of crops, even flowers, plants and the like with very strict cultivation requirements, the culture medium is suitable for mixing with any materials to be prepared into required media without limitations, and salinization conditions caused by excessive use can be avoided.

The invention discloses a method for preparing a solar greenhouse vegetable matrix, relates to a greenhouse fertilizer, and belongs to the field of fabrication of fertilizers. The solar greenhouse vegetable matrix is characterized by being prepared from the following materials by weight percent of 40-45% of preceding crop root, 5-10% of manure, 5-10% of a fungicide and 40-45% of traditional Chinese medicine waste residue. The solar greenhouse vegetable matrix has the beneficial effects that used materials are wastes of a pharmaceutical factory and agriculture; the solar greenhouse vegetable matrix is wide in source, low in cost, and good in cultivation effect, and the water and fertilizer maintaining ability of the prepared matrix is strong. The organic matrix is prepared according to the method disclosed by the invention; the wastes can be converted into precious resources; no pollution is generated in the production process; and the solar greenhouse vegetable matrix contains an organic matrix which is formed by inoculating trichoderma koningii into the preceding crop root and waste stems and leaves, an organic matrix which is formed by the collected manure, crop straws and calcareous shale by composting fermentation, the fungicide and the traditional Chinese medicine waste residues, so that the solar greenhouse vegetable matrix is complete in nutrition, and suitable for popularization, and can provide the enough nutrient content to the crops.
