Abstract
The invention provides a long-term and slow-release urea for drop irrigation, which is composed of the following components in parts by mass: 1000 parts of urea and 2-4 parts of polyaspartic acid. The invention further provides an application of the long-acting and slow-release urea for the drop irrigation to Sinkiang crops. By applying the long-acting and slow-release urea for the drop irrigation provided by the invention, a higher effectiveness of nitrogen, phosphorus and potassium nutrients in Sinkiang soil can be kept in all periods; the utilization rate of a nitrogen fertilizer is improved by 60.3 percent, the utilization rate of a phosphate fertilizer is improved by 5.3 percent and the utilization rate of a potassium fertilizer is improved by 16.7 percent. Under the condition of not decreasing the crop yield, chemical fertilizers in each mu of land can be saved by about 20 percent and symptoms of lacking nutritional elements are not easy to happen. When the fertilizers with the equal nutrients are applied, the yield of the Sinkiang crops can be increased by 10-20 percent through applying the long-acting and slow-release urea for the drop irrigation provided by the invention.
Description
Technical field
The present invention relates to a kind of drip irrigation and use long-acting slow-release urea.
Background technology
Xinjiang is temperate continental climate, has following characteristics: drying; Cold in winter and hot in summer; Day and night temperature is big; Sunshine is abundant.Drip irrigation is the most effective a kind of water saving irrigation mode in present drought and water shortage area.For the Xinjiang farm crop, it is lower with the urea average utilization to use common drip irrigation, and nutrient loss is serious, can pollute underground water and rivers and lakes like this; And the general not rate of release of easy-regulating nitrogen element; So that the progress of rate of release and crop absorption urea is synchronous; So if a large amount of urea of applied once cause the burning seedling easily in seedling stage; And, be difficult to again accomplish repeatedly to topdress, thereby cause farm crop owing to fertilizer deficiency and poor growth often owing to receive the restriction of manpower and cultivation condition.Therefore, need to provide the drip irrigation of a kind of suitable Xinjiang farm crop to use long-acting slow-release urea to the climatic characteristic in Xinjiang.
Summary of the invention
The technical problem that the present invention will solve is to overcome existing defective, provides the special-purpose drip irrigation of a kind of Xinjiang farm crop to use long-acting slow-release urea; The present invention also provides this drip irrigation with the application of long-acting slow-release urea in the farm crop of Xinjiang.
In order to solve the problems of the technologies described above, the invention provides a kind of drip irrigation and use long-acting slow-release urea, it is characterized in that: said drip irrigation is made up of the component of following mass fraction with long-acting slow-release urea: urea: 1000 parts, SAP 73: 2-4 part.
Further, said SAP 73 is 3 parts.
Further, in the said urea mass percent of nitrogen element more than or equal to 46%.
Further, said SAP 73 is available from Shijiazhuang Development Zone Desai Chemical Co., Ltd.
Second purpose of the present invention provides drip irrigation with the application of long-acting slow-release urea in the farm crop of Xinjiang.
Drip irrigation of the present invention uses the beneficial effect of long-acting slow-release urea to be:
1, drip irrigation of the present invention is with containing SAP 73 in the long-acting slow-release urea; Can strengthen the comprehensive absorption of crop to nitrogen, phosphorus, potassium and middle trace element; Thereby raising utilization rate of fertilizer; Increase crop yield, improve crop quality, avoided malnutritive and the malformed fruit that uses hormone to cause, bald point, dehiscent fruit, painted situation such as bad; Promote root growth simultaneously, strengthen resistance; And SAP 73 is nontoxic, harmless, fully biodegradable;
SAP 73 still is a kind of good anti-incrustation corrosion inhibitor, in drip irrigation system, is used the system jams that can avoid fouling and chemical precipitation to cause with urea, reduces the corrosion of fertilizer to system simultaneously;
SAP 73 has significant solublization to inorganic salt such as calcium sulfate, lime carbonate, calcium phosphate deposition and trace element, can effectively reduce the content of water-insoluble in the water soluble fertilizer, improves product percent of pass.
2, use drip irrigation of the present invention with long-acting slow-release urea after, nitrogen, phosphorus, potassium nutrition keep higher effective property in the soil of Xinjiang in each period, utilization rate of nitrogen fertilizer improves 60.3%, the utilization ratio of phosphate fertilizer improves 5.3%, the utilization ratio of potash fertilizer improves 16.7%.Under the situation that does not reduce crop yield, chemical fertilizer about 20% can be saved in every mu of ground, and is difficult for taking place nutritional deficiency symptom.When nutrient fertilizer such as applying, use drip irrigation of the present invention and can make Xinjiang increasing crop yield 10%-20% with long-acting slow-release urea.
