Embodiment 2

[0030] The preparation method of the medicinal fertilizer composition containing potassium phosphite, mineral source potassium fulvic acid, and polyglutamic acid of embodiment 2 comprises the following steps,

[0031] Step 1, add deionized water to the reaction kettle, then put in mineral source potassium fulvic acid, stir at room temperature for 30min, and the stirring speed is 100rpm;

[0032] Step 2, put potassium phosphite into the reaction kettle of step 1, adjust the pH to 6.5-7.5, raise the temperature to 55-60°C, and stir at a stirring speed of 200rpm for 1 hour to obtain chelated liquid A, which is taken out for later use;

[0033] Step 3, put polyglutamic acid into deionized water, stir at room temperature at a speed of 100rpm for 30min to obtain liquid B, take it out for later use;

[0034] Step 4: put liquid A and liquid B into a mixing reactor, stir at room temperature at a speed of 100 rpm for 30 minutes, take out and filter, obtain the filtrate, package, and obt...

Embodiment 2

[0036] The using method of the medicinal fertilizer composition containing potassium phosphite, mineral source potassium fulvic acid, polyglutamic acid of embodiment 2 comprises the following steps,

[0037] Ⅰ, take the medicinal fertilizer composition containing potassium phosphite, potassium fulvic acid, polyglutamic acid and 1 billion / ml Bacillus subtilis, 200 million / ml Bacillus licheniformis, 200 million / ml jelly samples The bacillus is mixed to obtain a mixed liquid medicine;

[0038] Ⅱ. Apply at the peanut seedling stage, before flowering, and after flower fall, and water the field after mixing the mixed medicinal solution with irrigation water, and apply at an amount of 5000g per mu.

[0039] Among them, the previous peanut crop is wheat, and the soil type is sandy loam with uniform soil fertility.

[0040] The test results are shown in Table 2.

Abstract

The invention relates to the field of fertilizers, and particularly relates to a pesticide-fertilizer composition containing potassium phosphite, mineral source potassium fulvate and polyglutamic acid. The composition comprises the potassium phosphite, the mineral source potassium fulvate and the polyglutamic acid in a weight ratio of (20-500): 1: (12-300), and can improve the crop yield and effectively inhibit root rot.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a medicinal fertilizer composition containing potassium phosphite, mineral source potassium fulvic acid and polyglutamic acid. Background technique [0002] Due to the long-term unreasonable application of chemical pesticides and chemical fertilizers, the soil pollution has been aggravated, and the single nutrient concentration in the soil is too high, which not only causes the stock of physical phase reactions in the soil to be too large, but also produces harmful substances in the soil, causing crop root damage. The difficulty of prevention and control is increasing, and the control effect is getting worse and worse, seriously affecting the growth of crops. At the same time, since most pesticides and fertilizers cannot be applied at the same time or affect their respective effects when applied together, pesticides and fertilizers need to be applied separately, which increases labor c...
