DETAILED DESCRIPTION - A special microbial organic fertilizer for Carthamus tinctorius comprises the following raw materials in mass parts: 250-600 parts of oil slag degradation product of Carthamus tinctorius seed oil, 300-600 parts of Carthamus tinctorius stem leaf, 100-300 parts of danty and 3-6 parts of microorganism bacterium agent as EM compound bacterium agent, where the oil slag of the Carthamus tinctorius seed oil is residual slag for filtering oil fat after squeezing, where the oil slag degradation product of Carthamus tinctorius seed oil is prepared by the following steps: using Bacillus subtilis CICC 10210 and Yarrowia lipolytica CICC 1444 strain to prepare Bacillus subtilis fermentation liquid and Yarrowia lipolytica fermentation liquid as the prior art, taking 50-80 parts of Bacillus subtilis fermentation liquid and 30-50 parts of Yarrowia lipolytica fermentation liquid as mass parts into 200-500 parts of the oil slag of Carthamus tinctorius seed oil, adjusting water content to be 45-55 wt.%, adjusting pH at 6.5-7.5, mixing fully, controlling temperature of material at 35-40 degrees C and placing for 6-8 hours; heating, timing when the temperature is increased to 100 degrees C, retaining for 25-35 minutes; and obtaining oil slag degradation product of Carthamus tinctorius seed oil. The preferable technical solution is as follows: the special microbial organic fertilizer for Carthamus tinctorius comprises the following raw materials in mass parts: 560-600 parts of oil slag degradation product of Carthamus tinctorius seed oil, 340-360 parts of Carthamus tinctorius stem leaf, 140-160 parts of danty and 3.5-4.5 parts of microorganism bacterium agent as EM compound bacterium agent. INDEPENDENT CLAIMS are included for the following: 1) preparation of the special microbial organic fertilizer for Carthamus tinctorius involving: using Bacillus subtilis CICC 10210 and Yarrowia lipolytica CICC 1444 strain to prepare Bacillus subtilis fermentation liquid and Yarrowia lipolytica fermentation liquid as the prior art, taking 50-80 parts of Bacillus subtilis fermentation liquid and 30-50 parts of Yarrowia lipolytica fermentation liquid as mass parts into 200-500 parts of the oil slag of Carthamus tinctorius seed oil, adjusting water content to be 45-55 wt.%, adjusting pH at 6.5-7.5, mixing fully, controlling temperature of material at 35-40 degrees C and placing for 6-8 hours; heating, timing when the temperature is increased to 100 degrees C, retaining for 25-35 minutes; and obtaining oil slag degradation product of Carthamus tinctorius seed oil; and breaking the dried Carthamus tinctorius stem leaf till the length is less than 0.5-1 cm for future use, taking the Carthamus tinctorius stem leaf, danty and microorganism bacterium agent as EM compound bacterium agent as mass parts, mixing fully, and mixing the mixture material with the oil slag degradation product of Carthamus tinctorius seed oil prepared in the above step; adjusting the content of the mixture material to be 55-65 wt.%, pilling and fermenting, timing when the temperature is increased to 55 degrees C, retaining for 4-6 days, turning pile, timing when the temperature is increased to 50 degrees C again and retaining for 4-6 days; repeating for 2-3 times as the operation of the way; obtaining fermenting material; drying the fermenting material in air or in oven till the water content is less than 20 wt.% to obtain powder product; or prilling the fermenting material by the prior art to obtain the particle product; and 2) application of special microbial organic fertilizer for Carthamus tinctorius, where 500-700 kg of fertilizer is used in each unit of area and the application method of the fertilizer involves spreading the fertilizer on the ground equably before sowing red flow in Spring and then turning to enable the fertilizer to be in the soil; applying once and not top-dressing.
