Description
Technical Field
The invention belongs to the technical field of fertilizer correlation, and particularly relates to a cotton drip irrigation fertilizer and a preparation and application method thereof.
Background
The water-soluble fertilizer is a water-soluble fertilizer, which is a multi-element compound type quick-acting fertilizer capable of being completely dissolved in water. The application method mainly comprises 3 methods: the fertilizer is applied along with water, cultivated in nutrient solution and sprayed on leaf surfaces, and has the characteristics of controllable formula, high nutrient absorption efficiency and the like.
After the fertilizer is dissolved, the fertilizer enters the soil solution, the nutrients close to the root surface are absorbed, the concentration is reduced, the concentration of the soil solution far away from the root surface is relatively high, and as a result, the nutrients are diffused, move to the root surface with low concentration and are finally absorbed.
China mainly plants cotton in Xinjiang, and Xinjiang has drought and water shortage, the agriculture is typical irrigation agriculture, the agriculture mainly depends on irrigation, and water is the most scarce resource in Xinjiang arid regions. With the development of water-saving technology, the water used in Xinjiang agriculture accounts for 96% of the total water consumption, so the key point of water saving is in agriculture. At present, the research of the high-efficiency water-saving irrigation technology becomes the most important demonstration area of the high-efficiency water-saving irrigation technology in domestic agriculture and the world.
The utilization rate of the fertilizer is improved, and the integrated technology of vigorously spreading the water-soluble fertilizer and promoting the water and fertilizer is imperative.
The existing drip irrigation water soluble fertilizer has an obvious defect that: on one hand, nitrogen in the fertilizer is catalyzed by urease generated by microorganisms and animal and plant tissues in soil and is easily hydrolyzed into ammonia and carbon dioxide; on the other hand, ammonium nitrogen in urea is easily converted into nitrate nitrogen by nitrifying bacteria in soil. The two defects easily cause harmful phenomena such as soil hardening, salinization, groundwater pollution and the like.
In summary, there is an urgent need for a cotton drip irrigation fertilizer that saves water resources, improves nitrogen utilization, and reduces environmental pollution, to solve the problems existing in the prior art.
