Embodiment 1
[0102] In the invention, nitrogen fertilizer and biochar are evenly applied to the target soil according to a specific ratio, so as to realize the goal of inhibiting phosphorus loss and improving phosphorus availability, and further improving the utilization rate of phosphorus fertilizer.
[0103] The nitrogen fertilizer is urea.
[0104] The biochar is general-purpose 95% biochar base fertilizer.
[0105] The soil is sandy soil, fluvio-aquic soil or sandy ginger soil.
[0106] The specific ratio is nitrogen fertilizer content:biochar content=1:1-3:1.
[0107] The crops are wheat, sorghum or corn.
[0108] The economic crops are cotton, rapeseed or soybean.
[0109] The organic matter and porous structure in the biochar of the present invention seal phosphorus, reduce the loss of phosphorus, and after combined with nitrogen fertilizer, activate the activity of soil microorganisms, also change the physical and chemical properties of soil to a certain extent, and promote Trans...
Embodiment 2
[0111] The method for improving the utilization rate of phosphate fertilizer by using the combination of nitrogen fertilizer and biochar, specifically includes the following steps:
[0112] (1) Design and manufacture test soil columns, such as figure 2 shown;
[0113] (2) Select the sandy soil used for the test;
[0114] (3) Mix nitrogen fertilizer and biochar in the ratio of 1:1, 2:1, 3:1.
[0115] (4) uniformly mixing nitrogen fertilizer and biochar mixture with the soil sample in step (2) in step (3);
[0116] (5) the mixture in the step (4) is put into the soil column in the step (1);
[0117] (6) Detect available phosphorus content in the sandy soil after 24h;
[0118] (7) Use a peristaltic pump to rinse the sandy soil, and detect the total phosphorus content in the rinse solution after 3 hours
[0119] (8) Compare the available phosphorus content and total phosphorus content obtained in step (4) and step (7) with the available phosphorus content and total phosphoru...
Embodiment 3
[0122] Embodiment 3: as figure 2 As shown, the method of using the combination of nitrogen fertilizer and biochar to improve the utilization rate of phosphorus fertilizer includes the following steps:
[0123] (1) Design and manufacture test soil columns, such as figure 2 shown;
[0124] (2) Select the river tidal soil used in the test;
[0125] (3) Mix nitrogen fertilizer and biochar in the ratio of 1:1, 2:1, 3:1.
[0126] (4) uniformly mixing nitrogen fertilizer and biochar mixture with the soil sample in step (2) in step (3);
[0127] (5) the mixture in the step (4) is put into the soil column in the step (1);
[0128] (6) After 24 hours, the available phosphorus content in the river fluvo soil is detected;
[0129] (7) Use a peristaltic pump to rinse the river fluvo soil, and detect the total phosphorus content in the rinse solution after 3 hours.
[0130] (8) Compare the available phosphorus content and total phosphorus content obtained in step (4) and step (7) wi...
