Problems solved by technology
[0002] CP (2-chloro-6-trichloromethylpyridine), DCD (dicyandiamide), and DMPP (3,4-dimethylpyrazole phosphate) are currently commercialized nitrification inhibitors; but DCD is highly toxic , easy to kill soil microorganisms, and to achieve 80% nitrification inhibition rate (ED80) needs 185ug / ml, easy to migrate and other disadvantages; although DMPP is relatively safe, the concentration required to achieve ED80 is 16ug / ml, and it is relatively expensive , it is difficult to be popularized in field crops

Abstract
The invention relates to a novel nitrogen and phosphorus synergist which contains 2-chloro-6-tricholormethyl pyridine phosphate and 2-chloro-6-tricholormethyl pyridine in weight ratio of 1: (2-10), preferably 1: 4. The novel nitrogen and phosphorus synergist has the beneficial effects that the insufficiency of the amount of degraded 2-chloro-6-tricholormethyl pyridine is supplemented, so that theeffective concentration time of the soil nitrifying inhibitor 2-chloro-6-tricholormethyl pyridine is prolonged, the aim of reducing the dosage and prolonging the inhibiting time of the nitrifying agent is achieved, and meanwhile, the degraded phosphoric acid is absorbed and utilized as a phosphatic fertilizer by plants, so that the soil is not polluted.
Description
technical field [0001] The invention relates to the technical field of nitrating agents, in particular to a nitrogen and phosphorus synergist. Background technique [0002] CP (2-chloro-6-trichloromethylpyridine), DCD (dicyandiamide), and DMPP (3,4-dimethylpyrazole phosphate) are currently commercialized nitrification inhibitors; but DCD is highly toxic , it is easy to kill soil microorganisms, and to achieve 80% nitrification inhibition rate (ED80) needs 185ug / ml, easy to migrate and other disadvantages; although DMPP is relatively safe, the concentration required to achieve ED80 is 16ug / ml, and it is relatively expensive , it is difficult to be popularized on field crops. Although the price of CP is not expensive, ED80 is only 4ug / ml, but due to its small solubility, it is easy to volatilize, and its half-life (DT50) in soil is about 21 days; application cost. [0003] Ammonium oxidation in the soil is mainly caused by the joint action of Nitrosomonas and Nitrobacter in...
