Problems solved by technology

So far, there is no high-efficiency and stable urea fertilization technology for crop cultivation models, so that good fertilizers do not have a good application technology to match them, and the best combination of cultivation models and fertilization technologies cannot be achieved. Therefore, the research is aimed at different crops. The specific fertilization technology of the cultivation mode is an inevitable requirement for the scientific application of new high-efficiency fertilizers

Abstract

The invention relates to an application technology of a high-efficiency stable urea fertilizer, in particular to an application method of the high-efficiency stable urea fertilizer in northern rice wide-narrow row cultivation. Rice is planted in a wide-narrow row rice cultivation mode, and the high-efficiency stable urea fertilizer is correspondingly applied in the rice transplanting process and the rice tillering stage. The application method is a novel high-efficiency stable fertilizer application technology combining a novel rice cultivation mode and a high-efficiency stable urea fertilizer application technology adapted to the novel rice cultivation mode. The application method is a novel fertilizer application technology combining the novel rice cultivation mode and the novel high-efficiency stable urea fertilizer for optimizing the ventilation and light transmission environment of a rice field, enhancing the absorption of the rice to fertilizer nutrients, and giving full play to the rice yield increasing potential.

Description

technical field [0001] The invention relates to the application technology of high-efficiency and stable urea fertilizer, in particular to an application method of high-efficiency and stable urea fertilizer in the wide and narrow row cultivation of northern rice. Background technique [0002] Efficient and stable urea fertilizer is a new type of urea nitrogen fertilizer. At present, industrialized production and large-scale promotion and application have been carried out. Its core technology is to use biochemical inhibitors to control the hydrolysis and nitrogen conversion rate of urea in the soil, prolong the effective period of urea in the soil, realize one-time fertilization when crops are sown, and apply less or no top-dressing fertilizer during crop growth, which can effectively To improve the nitrogen utilization rate of urea nitrogen fertilizer, if combined with crop cultivation technology for scientific fertilization, the nitrogen utilization rate can be increased b...
