Description
Technical Field
The invention belongs to the technical field of mineral compound fertilizers, and particularly relates to a desert few-pulp xerophyte mineral compound fertilizer and application thereof.
Background
Drought is one of the most serious ecological environmental problems facing mankind. According to statistics, the land area of the world arid and semiarid regions occupies one third of the global land area, and the arid and semiarid regions in China occupy about 50% of the national soil area; particularly, in northwest regions with fragile ecological environment in China, desertification (sand) is particularly serious due to extreme drought and little rain, and the desert is one of the most serious countries in the world. In the face of the continuous degradation of the natural ecosystem caused by drought worldwide, scientists in various countries try to suppress the serious environmental problem of land desertification by promoting the growth of desert plants and enhancing the drought-resistant adaptability thereof, but no effective method has been found so far. Therefore, how to maintain the functions of the ecosystem in the arid region and accelerate the recovery process of the degraded ecosystem in the arid region is a scientific problem to be solved urgently at present.
Areas with serious wind and sand disasters in China are mostly distributed in arid desert areas, the areas are characterized by poor precipitation and large variation, the evapotranspiration amount of the areas is 210 times of the precipitation amount generally, and water resources are very deficient. The desert xerophyte is an important resource plant in the arid region in the northwest of China, integrates the functions of wind prevention and sand fixation, water and soil conservation, excellent pasture and traditional Chinese medicinal materials and the like, and plays an extremely important role in maintaining the ecological balance of the arid desert region in China, promoting the ecological construction and economic development of the arid region and the like. However, the natural conditions in the desert area are continuously worsened due to global climate change, and the underground water level is reduced due to the wild Chinese medicinal materials which are excessively grazed and abused by human activities and unreasonable utilization of water resources, so that the important resource plants are gradually degenerated and died, and the desert spreading speed is accelerated. The problems of gradual decline and difficult rejuvenation and updating of desert plants have attracted extensive attention in the academic world, the updating problem gradually becomes a main factor for restricting the desert plants from developing ecological benefits, and how to ensure the rejuvenation and updating of desert vegetation through practical artificial measures under limited rainfall becomes very important. However, desert xerophytes widely distributed in northwest arid regions of China gradually evolve a unique adaptive mechanism in the long-term natural selection and adaptive evolution process, and have super-strong drought resistance and good adaptability to desert habitat.
In recent years, researches show that mineral nutrition plays an important role in drought resistance of desert low-pulp plants. For xerophytes with little serosity, K is accumulated+And organic solutes are their effective adaptation mechanisms against arid desert habitats. The small-pulp drought plants have drought-resistant adaptability characteristic mainly based on accumulated ions, and a large amount of absorbed and accumulated K+、Ca2+Si and a proper amount of organic solute are important strategies for resisting drought habitat of the small-pulp plants, and the contribution of Si accumulation to drought resistance of the small-pulp drought plants and Mg2+ApproximatelyThe small-pulp xerophyte has high accumulation of nitrogen (N) but low accumulation of phosphorus (P), shows an important adaptability characteristic that a large amount of N is accumulated to reject P, has low demand of phosphorus for the desert small-pulp xerophyte, and can meet the growth requirement of the desert small-pulp xerophyte with low concentration of phosphorus.
In arid desert regions, mineral nutrition which can be absorbed and utilized by plants is very deficient, and the absorption of mineral nutrition by desert plants with less pulp is beneficial to enhancing the drought resistance adaptability of the plants. As an important resource plant in desert regions, namely the drought-resistant plants with less pulp, no related report exists for enhancing the drought resistance of the drought-resistant plants with less pulp.
