Embodiment 1

[0020] The effect of phosphorus activator on the activation of phosphorus in alkaline loess soil:

[0021] The application rate of phosphorus activator is 15000kg / hm of furfural slag 2 , Potassium sulfate 300kg / hm 2 , phosphate solubilizer 0.6kg / hm 2 , wood vinegar 25kg / hm 2 . The loess soil used in the experiment was the plow layer soil of Tianshui farmland, which was divided into control (CK 0 , do not apply any fertilizer), phosphate fertilizer 225kg / hm 2 (P 15 ), Phosphate fertilizer 225kg / hm 2 +Organic fertilizer 7500kg / hm 2 (MP 15 ), and the treatment with phosphorus activator was denoted as (CK 2 ,P 15-2 and MP 15-2 ). According to the above-mentioned design application rate of phosphorus activator, mix each component with loess soil evenly, and put 300g (passed through a 2-mm sieve) into a plastic cup, and add deionized water according to 70% of the field water capacity. Plastic cups are sealed with plastic wrap, and a small hole is left in the middle of...

Embodiment 2

[0023] Effects of phosphorus activators on wheat biomass:

[0024] The application amount of phosphorus activator is the same as embodiment 1. According to the designed application rate, mix each component with loess soil evenly, and place 1 kg (passed through a 2-mm sieve) in a plastic pot, and add deionized water according to 70% of the field water capacity. The plastic pots were aged in a constant temperature incubator at 25°C for 1 day, and the seeds were sown on the 2nd day. During the test, water was added uniformly depending on the degree of drought of the soil, and the amount of added water for all treatments remained the same. Each treatment was repeated 4 times, and the treatment without phosphorus activator was set as the control, and the culture experiment lasted for 60 days. The effect of phosphorus activator application on wheat biomass figure 2 , the test results showed that for the blank control, the phosphorus activator could significantly increase the b...

Embodiment 3

[0026] Effects of phosphorus activators on total phosphorus content of wheat plants:

[0027] The application amount of phosphorus activator is the same as embodiment 1, and the test operation process is the same as embodiment 2. The influence of phosphorus activator on the total phosphorus content of wheat plants is shown in the appendix image 3 . For the blank control, the phosphorus activator can significantly increase the total phosphorus content of wheat plants, and the increase rate is 27.0%; Increase the total phosphorus content of wheat plants by 1.21% and 15.4%, respectively.

Abstract

The invention discloses an alkaline soil phosphorus activator, which is prepared by combining furfural residue, potassium sulphate, wood vinegar and phosphate-solubilizing bacteria agent. The alkaline soil phosphorus activator disclosed by the invention contains rich nutrient elements such as organic matter, nitrogen phosphorus and potassium, and also contains rich phosphate-solubilizing bacteria, applying the alkaline soil phosphorus activator in alkaline soil can increase the rapid available phosphorus content of the soil, increase the phosphorus supply capacity of the soil, enhance the nutrient absorption of crop and increase the yield of the crop, and thereby the application of phosphate fertilizer can be reduced. The added phosphate-solubilizing bacteria agent plays the role of activating both the original phosphorus and applied phosphate fertilizer in soil and has a longer duration of activation, and moreover, the phosphate-solubilizing bacteria agent can increase the yield of crops and promote the accumulation of nutrient elements in crops, and also can enhance the fertility of soil. The alkaline soil phosphorus activator is quite suitable for activating alkaline soil phosphorus. By limiting the dosage ratio of the furfural residue, the potassium sulphate, the wood vinegar and the phosphate-solubilizing bacteria agent, the utilization rate of phosphorus fertilizer is greatly increased, and the usage of phosphorus fertilizer in soil is reduced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an alkaline soil phosphorus activator capable of activating alkaline soil phosphorus. Background technique [0002] There is a large area of ​​alkaline soil distributed in our country. Alkaline soil has a strong fixation effect on phosphorus, and calcium phosphate precipitation is easy to form, making the soil generally deficient in phosphorus. Insufficient phosphorus supply is one of the most important limiting factors for agricultural production in alkaline soil areas. one. There are two main ways to solve the problem of soil phosphorus deficiency: one is to increase the amount of phosphorus fertilizer applied, and the other is to increase the utilization rate of phosphorus fertilizer. Phosphorus is a non-renewable resource, and the phosphate rock resources in our country are very poor. From the perspective of sustainable agricultural development, it is a practical and f...
