Rice is one of the crops that need more nitrogen. In China, the average amount of nitrogen used is 18-20kg per mu, and the nitrogen use efficiency is about 35%. In recent years, excessive application of nitrogen fertilizer has caused agricultural non-point source pollution. How to reduce the amount of nitrogen fertilizer applied to rice has become a common concern in rice production.
However, Huaqiang NPK fertilizer production equipment manufacturer has carried out experiments on modified urea, and has processed urea compound fertilizer by using new NPK fertilizer production process. This paper discusses the production status of rice and other crops when the conventional nitrogen fertilizer application rate is reduced by half. This kind of fertilizer is a new type of urea which mainly contains active small molecules of natural organic matter and is made up of bio energy, plant nutrient source and precursor of growth transfer factor.
The application results showed that the application of the new compound urea reduced 40% of the nitrogen fertilizer application, and the rice yield and economic benefits were significantly increased, which could be popularized and applied in rice production; the application of modified urea could save nitrogen fertilizer application amount, greatly save energy consumption, achieve the purpose of low carbon consumption, and reduce agricultural pollution sources with less nitrogen fertilizer application; Application of modified urea can also reduce transportation cost, labor intensity and field operation time.
Organic fertilizer equipment roller press granulator
The small-molecule organic compound fertilizer was tried on rice planting. The amount of rice was 40-50kg per acre during the whole growth period. It was used in the base fertilizer, tiller fertilizer, and ear fertilizer period respectively, and the average grain yield increased by 36kg/667㎡. Variety of fertilizers to achieve an increase in output and efficiency of 55 yuan/667 square meters. The application of modified urea in the experimental paddy field has achieved significant labor saving, cost saving and income increase, and the quality has been improved.
The mixed urea and NPK fertilizer are made into granules in proportion by double roller press granulator, which improves the fertilizer efficiency of original urea. Compared with ordinary urea, the yield of rice increased by 10% per mu, and the fertilizer application time of farmers was reduced, and the transportation cost was saved.
The compound fertilizer processed by NPK fertilizer production process has been applied to improve the quality and taste of fruits and vegetables. Compared with the use of ordinary urea, the yield of compound fertilizer per mu is increased by 20% - 40%.
It can keep bolls, reduce bud shedding, prolong flowering and boll opening periods, increase silk length and silk whiteness, and greatly improve the yield and grade of cotton. Compared with the use of ordinary urea, the yield per mu is increased by 10% - 25%, and the cotton fields with modified urea are sold at a good price.
Using it on soybeans can prolong the flowering period and pod setting period, greatly increase the number of pods, and the grains are full, which increases the yield per mu by 15% to 30% compared to using ordinary urea.
A large number of experiments have proved that the new urea fertilizer processed by the NPK fertilizer manufacturing process fully meets the needs of modern agricultural production.
