Wheat proprietary formula Loss-controlled fertilizer and Common compound fertilizer fertilizer efficiency comparative test, test carry out in Anhui along Huaihe River Northern Area of Huaihe River, point
4 points have not been selected.Experimental field topography is flat, and fertility is uniform, medium, and can fill can arrange.
2. material and method: 4 pieces of selection experimental field except soil fertility quality Bu Tong in addition to, progress weeding, the complete phase such as diseases prevention
Same field management measure.Common chemical fertilizer is applied in control group field, and the life of 1-5 of embodiment of the present invention preparation is added in test group field respectively
Substance fertilizer is 400-800g/ kilograms.It applies fertilizer at the same time, examines nitrogen, P elements, potassium element in soil before applying fertilizer
Content and soil pH value.The content of nitrogen in soil, P elements, potassium element is examined after fertilising a period of time again.
3. test data result is as follows: nitrogen, P elements, the weight ratio of potassium element in fertilising are 5:1:1.It applies per acre
Fertile 50kg, according to 667 square meter per acre, the thick 0.2 meter of calculating of soil, the weight of soil is 150 tons or so per acre, i.e., every kilogram average
The amount of organic fertilizer material is 330mg in soil；The weight of nitrogen is applied in every kilogram of soil for 235.7mg, in every kilogram of soil
The weight for applying P elements is 47.1mg, and the weight that potassium element is applied in every kilogram of soil is 47.1mg.
Each component content in soil before testing:
Each component content in soil after test
Data are displayed without addition biomass fertilizers control field, and the leaching test group of moisture and nutrient is serious, this be by
In preparation biomass fertilizers, bamboo scraps internal structure has carried out loose, causes the structure of bamboo scraps hole occur, is conducive in subsequent corruption
Middle storage oxygen is lost, Decayed rate is promoted and fertilizer energy, cavity is beneficial to prevent soil moisture, nutrient loss.
It should be understood by those ordinary skilled in the art that: the discussion of any of the above embodiment is exemplary only, not
It is intended to imply that the scope of the present disclosure (including claim) is limited to these examples；Under thinking of the invention, above embodiments
Or can also be combined between the technical characteristic in different embodiments, step can be realized with random order, and be existed such as
