Problems solved by technology

For a long time, the fertilization of mustard mustard has the problem of unreasonable nutrient mix and heavy nitrogen fertilizer, which makes the content of nitrate and nitrite in mustard tuber stem exceed the standard, which is not conducive to health after eating, and seriously affects the export of pickled mustard products
Moreover, ordinary compound fertilizers are easy to lose nitrogen, and the utilization rate of fertilizers is low, resulting in a continuous increase in the amount of nitrogen fertilizer, but little increase in yield, which aggravates environmental pollution and other problems.
At the same time, farmers need to fertilize many times in mustard planting, which is complicated and increases labor costs.

Embodiment 1

[0030] Preparation of polyaspartate

[0031] Add 700L of deionized water into a 1000L reactor, heat to 45°C, add 125kg of potassium carbonate under stirring conditions, then add 165kg of polysuccinimide with a molecular weight of 3000-7000, hydrolyze for 300min, and filter to obtain potassium polyaspartate solution .

Embodiment 2

[0033] Preparation of Special Fertilizer for Mustard Mustard

[0034] Weigh basic fertilizers, including 243kg of ammonium nitrate, 75kg of monoammonium phosphate and 90kg of potassium chloride, 6.35L of potassium polyaspartate solution, 3kg of sodium benzoate, 1kg of 2-chloro-6-trichloromethylpyridine, dicyandiamide Amine 2kg, borax 4kg spare. Potassium polyaspartate, sodium benzoate, 2-chloro-6-trichloromethylpyridine, dicyandiamide, borax and potassium chloride are fully mixed to obtain a potassium chloride mixture containing a synergist and a nitrification inhibitor, Transfer this mixture together with ammonium nitrate and monoammonium phosphate to a granulator for granulation, and sieve the granulated products. After crushing, the large-grained products and fine powder are re-granulated together with the raw materials. The product is dried until the water content is lower than 2%, and after the dried product is cooled, an anti-caking agent is added to obtain a special fe...

Abstract

The invention discloses a special fertilizer for preserved Szechuan pickle, which comprises the following components in percentage by weight: 25-50% of a base fertilizer (based on the sum of N, P2O5 and K2O), 0.2-20% of a synergist and 1-3% of a nitrification inhibitor, wherein the weight ratio of N to P2O5 to K2O in the base fertilizer is (1.8-2.2):(0.9-1.1):(1.1-1.3). The synergist is polyaspartic acid salt, and the nitrification inhibitor is one of or mixture of more of sodium benzoate, 3,4-dimethylpyrazole phosphate, 2-chloro-6-tri(chloromethylpyridine), dicyandiamide, resorcinol and borax. By introducing the polyaspartic acid salt and nitrification inhibitor into the base fertilizer, the utilization rate of the preserved Szechuan pickle on the nutritional elements of the fertilizer can be improved, the loss of nitrogen in soil can be slowed down, finally the increment of the preserved Szechuan pickle can be realized through the disposable fertilizer application, and the contents of nitrates and nitrites in the preserved Szechuan pickle can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of crop fertilizers, in particular to a special fertilizer for mustard mustard and a preparation method thereof. Background technique [0002] Pickled mustard is an important processed stem vegetable in my country. Its processed products are fresh, fragrant, tender and crisp, together with French pickled cucumbers and German sweet and sour cabbage. It is also known as the world's three famous pickles. For a long time, the fertilization of mustard mustard has the problem of unreasonable nutrient mix and heavy nitrogen fertilizer, which makes the content of nitrate and nitrite in mustard tuber stems exceed the standard, which is not conducive to health after eating, and seriously affects the export of pickled mustard products. Moreover, ordinary compound fertilizers are easy to lose nitrogen, and the utilization rate of fertilizers is low, resulting in a continuous increase in the amount of nitrogen fertilizer...
