NOVELTY - A cucumber slow release fertilizer comprises rice washing water, quartz sand, corn straw, bagasse, Chinese cabbage, soybean cake, duck manure, shell powder, corncob, effective microorganism biological bacteria agent, diammonium phosphate, potassium iodide, sodium molybdate, ammonium chloride, potassium sulfate, phosphate fertilizer, starch, propylene glycol, urea-formaldehyde resin, sodium dodecyl sulfate, auxiliary agent, and water.    USE - Cucumber slow release fertilizer.    ADVANTAGE - The slow release fertilizer reduces labor burden, utilizes and recycles waste materials, and it has reduced dosage and great anti-soil compaction effect.    DETAILED DESCRIPTION - A cucumber slow release fertilizer comprises 14-16 pts. wt. rice washing water, 8-11 pts. wt. quartz sand, 8-10 pts. wt. corn straw, 7-9 pts. wt. bagasse, 12-15 pts. wt. Chinese cabbage, 7-8 pts. wt. soybean cake, 9-11 pts. wt. duck manure, 4-6 pts. wt. shell powder, 8-10 pts. wt. corncob, 2-3 pts. wt. effective microorganism biological bacteria agent, 6-8 pts. wt. diammonium phosphate, 4-6 pts. wt. potassium iodide, 4-5 pts. wt. sodium molybdate, 10-12 pts. wt. ammonium chloride, 8-11 pts. wt. potassium sulfate, 12-15 pts. wt. phosphate fertilizer, 2-3 pts. wt. starch, 1-2 pts. wt. propylene glycol, 6-8 pts. wt. urea-formaldehyde resin, 2-3 pts. wt. sodium dodecyl sulfate, 5-6 pts. wt. auxiliary agent, and balance water. The auxiliary agent comprises 6-7 pts. wt. agar, 3-4 pts. wt. ethylene glycol dimethacrylate, 1-2 pts. wt. bamboo coal powder, 7-9 pts. wt. borax, 5-6 pts. wt. zinc borate, 3-5 pts. wt. glycerol, 1-2 pts. wt. zinc sulfate, 2-3 pts. wt. ammonium molybdate, 10-14 pts. wt. starch, and balance water. The auxiliary agent is prepared by mixing agar and starch, adding 50 pts. wt. water, heating while stirring to dissolve, adding remaining components, continuously heating while stirring for 70-80 minutes, and cooling to room temperature. An INDEPENDENT CLAIM is included for preparation of slow-release fertilizer comprising crushing quartz sand, corn straw, bagasse, Chinese cabbage, soybean cake, duck manure, shell powder and corncob into 160 mesh ultrafine dry powder, adding effective microorganism biological bacteria agent, diluting with 10 times water, adjusting water content to 30-35% with rice washing water, and fermenting to 38-45 degrees C for 20-24 days while turning once every 2 days; mixing diammonium phosphate, potassium iodide, sodium molybdate, ammonium chloride, potassium sulfate and phosphate fertilizer, adding 5-6 times water, heating while stirring to dissolve, adding starch, propylene glycol, urea-formaldehyde resin and sodium dodecyl sulfate, and stirring for 10-15 minutes to obtain mixture; adding quartz sand, and heating while stirring constantly for 40-50 minutes to obtain gummy mixture; and mixing with fermented material, adding auxiliary agent, mechanically stirring for 30-40 minutes, and granulating.
