Problems solved by technology
A large number of domestic and foreign statistical data show that long-term large-scale application of chemical fertilizers is not effective, which deteriorates the ecological environment and reduces the quality of agricultural products.
According to statistics, about 50 billion yuan of nitrogen fertilizers are not used in my country every year and enter the environment, causing pollution to rivers, rivers, lakes and groundwater, increasing agricultural production costs, and reducing farmers' income.
The problems existing in large-scale agricultural production are: low utilization rate of nitrogen fertilizer and large losses. Therefore, how to improve the utilization rate of nitrogen fertilizer and strengthen its long-term efficiency is a difficult problem in the field of chemical fertilizers in the world, and it is also a research hotspot.
There have been some problems in the implementation of this patent for many years. On the one hand, the manufacturer of the water-retaining agent for soil maintenance and maintenance makes granules, and the farmers themselves mix nitrogen fertilizers according to the specified ratio when applying, which leads to uneven mixing and uneven mixing ratios. On the other hand, it is inconvenient to apply and lacks organic matter. The name of the patented "soil nourishment, maintenance and water retention agent" is not easily accepted by farmers, which affects popularization and application. Therefore, the inventor has improved on this basis to make it Complete

Embodiment Construction
[0053] Crush the selected attapulgite into 100 meshes and mix with urea and sodium humate. The three are mechanically blended and then granulated. To prepare 100 kg of new slow-release drought-resistant nitrogen fertilizer, take 50 kg of attapulgite powder, 40 kg of urea, and 10 kg of sodium humate, mix and granulate evenly.

Abstract
The invention relates to fertilizer, in particular to novel slow-release drought-resisting nitrogenous fertilizer. The novel slow-release drought-resisting nitrogenous fertilizer comprises iodine-containing attapulgite which is specially produced in Gansu, is peculiar in the world and is used as a main raw material, urea and sodium humate. The invention can enhance the utilization rate of the nitrogenous fertilizer by more than 6-25%, adsorb nitrogen elements, reduce the loss and save the nitrogenous fertilizer by 40-60%. The invention can absorb water, avoid drain and evaporation and enhancethe content of soil moisture by 28-30% and has the function of drought resistance. The invention can improve the soil, such as increasing granular structure of soil, loosening the soil, enhancing thesubstitution quantity, governing saline and alkali and the like. The invention can increase the production, increase the yield, enhance the quality and greatly enhance the crude protein and the starchof food crops and the Vc, the sugar content, the protein and the oil yield of economic crops. The invention can greatly reduce the nitrogen elements entering the environment and has a very obvious function of protecting the ecological environment.
Description
technical field [0001] The invention relates to a fertilizer, in particular to a novel slow-release drought-resistant nitrogen fertilizer. Background technique [0002] Nitrogen fertilizer is the "food" of crops, and there is no other substitute today. my country is a big producer of chemical fertilizers, which reached 43.75 million tons (pure conversion) in 2003. Among them, nitrogen is 28.8 million tons, which is equivalent to 62.6 million tons of urea. Chemical fertilizer input accounts for more than 50% of agricultural production input. Every year, farmers spend more than 140 billion yuan on chemical fertilizer, which shows the importance of chemical fertilizer in agricultural production. "It has contributed a lot to human beings, but the long-term large-scale and improper application of chemical fertilizers has very serious negative effects. At present, the utilization rate of chemical fertilizers is low, only 35% to 50% are used, and the loss is large. For example, a...
