Abstract
Synergist and nitrogen protective agent for urea is that a kind of soil, plant mix conditioning agent.Form by quinhydrones, zinc sulfate and the mixing of carrier dry powder coal ash.It and urea mix use, can effectively suppress urease activity in the soil, delay the decomposition rate of ammonia in the urea, and participate in the synthetic of growth hormone in plant materials, promote its metabolic process.To chlorophyll and proteinic synthetic, photosynthesis reaches all has promotion and conciliation effect to nitrogen, phosphorus, absorbing of potassium.Production technique of the present invention is simply applied widely, and is easy to use.According to the needs of soil and Different Crop, can adjust blending ratio during use at any time with urea.
Description
The present invention is a kind of synergist and nitrogen protective agent for urea, and it belongs to edaphophyte mixing conditioning agent.Form by quinhydrones, little fertilizer and carrier.
Improving utilization rate of nitrogen fertilizer is one of important method that increases by chemical fertilizer, and the measure of this respect is a lot.Chinese patent CN85109580 discloses a kind of long-acting carbamide that contains urease inhibitor-quinhydrones (Resorcinol).Urease inhibitor can effectively suppress urease activity in the soil, delays the conversion of urea ammonia, to reduce the urea efficiency loss, improves the utilization ratio of urea.But quinhydrones in long-acting carbamide (Resorcinol) content is fixed, can not adapt to different soils type fertilising needs.
The purpose of this invention is to provide a kind of mixing conditioning agent that contains quinhydrones, little fertilizer and carrier, this mixing conditioning agent mixes use with urea, can effectively suppress urease activity in the soil, delay the conversion of urea ammonia and effects such as promotion plant metabolism, absorbed nitrogen, phosphorus, potassium are arranged.
Purpose of the present invention can be reached by following measure: zinc is nutritive element necessary in the growing process, and its participates in the synthetic of growth hormone, and to chlorophyll and proteinic synthetic photosynthesis, redox normally all have an effect.Little fertile zinc sulfate, carrier dry powder coal ash of using of the present invention.To mix through quinhydrones (Resorcinol), zinc sulfate, the dry powder coal ash that sieves, pulverizes, promptly make synergist and nitrogen protective agent for urea after grinding, the weight ratio of quinhydrones (Resorcinol) zinc sulfate, dry powder coal ash accounts for 10～15%, 15～20%, 65～75% of gross weight respectively.
Advantage of the present invention is that synergist and nitrogen protective agent for urea mixes use (by 1: 50 weight ratio) and can improve the farm crop quality with urea, improves protein, nitrogen content in the cereal vegetables, reduces nitrate content.Mix the use consumption with urea little, safe and reliable, reduces and pollute.Wherein:
1, the effect of quinhydrones can improve utilization rate of nitrogen fertilizer 6～11%, prolongs 30～50 days fertilizer effectiveness phases, and effect of increasing production is 6～10%
2, plant increases the zinc fertilizer advantage in order to regulate, disease resistance participates in growth hormone and synthesizes, and promotes nitrogen absorption and utilization.
3, owing to quinhydrones, zinc sulfate are adsorbed in (grinding has produced micro-static induction) on the brownish carrier dry powder coal ash uniformly, like this, whole mixing conditioning agent can be distinguished mutually with urea on color.
Composition of the present invention is seen accompanying drawing.
