The controlled-release organic microbial fertilizer prepared by the invention is tested by a water immersion method to test the nutrient release effect of the fertilizer. The specific test method is as follows: weighing 50g of the fertilizer prepared in the embodiment 1 of the invention, putting the fertilizer into a small bag made of a 100-mesh nylon gauze, sealing the small bag, putting the small bag into a 1000ml glass bottle, adding 500ml of distilled water, capping and sealing the small bag, putting the small bag into a biochemical constant-temperature incubator at 25 ℃ for culture, then respectively sampling in 1 st, 3 rd, 5 th, 7 th, 9 th, 12 th, 24 th, 48 th, 56 th, 84 th and 112 th days of culture, inverting the bottle three times from top to bottom during sampling to enable the concentration of liquid in the bottle to be consistent, and transferring the bottle into another glass bottle for nutrient determination. Then, 500ml of distilled water is added into a glass bottle of a small bag filled with the fertilizer, the glass bottle is covered and sealed, then the glass bottle is placed into a biochemical constant temperature incubator, the steps are repeated for continuous culture, and the fertilizer is subjected to 3 times of repeated tests. The determination was carried out according to the specifications of HG/T3931-2007 and HG/T3997-2008. The fertilizer has the advantages that the accumulated release rate of nitrogen in 7 days is 7.6%, the accumulated release rate of potassium in 7 days is 6.11%, and the accumulated release rate of phosphorus in 7 days is 4.72%, namely the initial release rates of nitrogen, phosphorus and potassium elements are low, the release of nutrients is accelerated after 40 days, the release of nutrients is slowed after 100 days, and the total release period of the nutrients can reach 112 days. The nutrient release characteristics completely accord with the absorption trend of N, P, K 'less-more-less' of crops in the growth period, so that one-time fertilization of the crop growth period is realized, and the effects of increasing the yield and the income of the crops are obvious.

The fertilizer disclosed by the invention is used for planting the Chinese cabbages, and the application effect of the fertilizer on the Chinese cabbages in the planting process is researched. The test materials and the specific method were as follows: a certain vegetable planting land in Juzhou county, Shandong province is selected as a Chinese cabbage planting test land, the variety of the Chinese cabbage is Lubai III, the Chinese cabbage is planted in a conventional mode, one plant is planted in each hole, and the planting density is 3 plants/m 2. The soil conditions were: 0.272g/kg of total nitrogen, 35.6g/kg of organic matters, 182.5mg/kg of quick-acting nitrogen, 8.7mg/kg of quick-acting phosphorus and 98.2mg/kg of quick-acting potassium. The test was divided into 6 fertilization treatment groups, each treatment group having the same area, wherein 1 group was the fertilizer group prepared in example 1; groups 2-5 are the fertilizers prepared in comparative examples 1-3; 6 groups are blank control examples, the controlled-release organic microbial fertilizer in the example 1 is adopted, the fertilizer using amount of each fertilizer treatment group is the same, wherein the fertilizer of 1-5 groups is used as a base fertilizer for ditching and one-time application after sowing, the 6 th group fertilizer is 60 percent of base fertilizer, and the rosette stage is additionally applied by 40 percent. Other management measures are the same as those in the local field. All fruits were picked at harvest time, weighed to account for yield and 10 plants were randomly selected in each treatment group and the average individual plant bulb mass was calculated. In addition, the invention also researches the quality of the Chinese cabbages of each treatment group, and each treatment group is repeated for 3 times. The specific results are shown in tables 1-2.
