The specific fertilization mode is that the calcium superphosphate, the potassium sulfate and the prepared biological organic fertilizer are used as base fertilizers to be applied to soil, the three fertilizers are firstly spread on the surface of the soil together, and then ploughing and sowing are carried out. The application amount of the calcium superphosphate is 600kg/hm2The application amount of the potassium sulfate is 90kg/hm2. The application rates of the biological organic fertilizer 1-the biological organic fertilizer 4 in the 4 test groups are respectively 15t/hm2、45t/hm2、60t/hm2、75t/hm2. The control group did not apply bio-organic fertilizer, and the fertilizer application method was the same as the test group. In the seedling stage of spring wheat, urea is applied once for each group, and the application amount of urea is 150kg/hm2。
Selecting Ningchun No. 4 as a test variety, and performing the test in the last ten days of 3 months according to the ratio of 270kg/hm2Sowing the seeds at the sowing rate, performing the same conventional management on each district, and harvesting in 7 middle of the month. Before harvesting spring wheat, selecting 15 plants from each cell, manually harvesting the whole spring wheat, then testing seeds, and measuring plant height, ear dry weight, stem dry weight and leaf dry weight. After the spring wheat is harvested, the yield of each cell is counted. Calculating each groupAverage plant height, average ear dry weight, average stem dry weight, average leaf dry weight, and average cell spring wheat yield of spring wheat. The results are shown in Table 1.
