Description
Technical Field
The invention relates to the technical field of soil fertilizers, in particular to a package fertilizer special for increasing yield and preventing diseases and insect pests of soybeans and an application method thereof.
Background
The soybeans originally originate from China, have a planting history of about 5000 years to date, are one of main food crops and oil crops in China, and play an important role in agricultural production. In the process of soybean production, the improvement of soybean yield and the reduction of input cost are particularly important, and not only needs to select improved varieties suitable for local natural conditions to carry out crop rotation cultivation, avoid continuous cropping and timely seeding, but also needs to carry out scientific field management and reasonable fertilization.
Molybdenum is one of essential trace elements for crop growth and development, participates in the formation of azotase, can promote the generation and development of root nodules, improves the nitrogen fixation activity and capacity of rhizobia, and is indispensable for biological nitrogen fixation of leguminous plant rhizobia and various self-growing nitrogen fixation bacteria. The content of molybdenum in soil in China is very low, generally about 2mg/Kg, and most molybdenum exists in a form of being insoluble in water, so that crops cannot absorb and utilize the molybdenum. Therefore, the development of the molybdenum-containing high-efficiency soybean special fertilizer has great significance for promoting the absorption of soybean root systems to major elements such as nitrogen, phosphorus, potassium and the like, enhancing the growth vigor of plants, promoting photosynthesis and improving the yield and quality of soybeans.
In addition, the soybean cyst nematode disease is a devastating disease in the world soybean production, when soybeans are planted in continuous cropping, the overground part shows that the leaves of soybean plants turn yellow after being damaged by the cyst nematode, the edges of the light leaves turn yellow, and the yield is obviously reduced; the soybean leaves of serious plants turn yellow completely, and some plants die, so that the root systems of the soybeans are mainly damaged in the underground part, the development of the root systems is retarded, the absorption of the root systems to nutrition and moisture is damaged, and the number of the nitrogen-fixing rhizobia of the soybeans is reduced. Meanwhile, the openness of the surface of the bean roots is increased, the damages of other soil-borne diseases such as damping off, fusarium root rot, phytophthora root rot and anthracnose are increased, and even the soybean cannot be produced before or after blooming.
At present, a one-shot fertilization mode is adopted in soybean production, so that excessive fertilizer application is caused, the utilization rate of the fertilizer is low, and diseases and insect pests are frequent. In order to solve the outstanding problems, domestic soybean related scientific research personnel also provide soybean recommended fertilization methods, such as soil testing formula fertilization, a fertilizer effect function method, nutrient precise management and the like, and particularly, the traditional recommended fertilization method based on the soil testing formula plays an important role in soybean yield increase. However, soil testing assays are time consuming, labor intensive, and require some financial investment; in addition, the soil nutrient test value cannot completely reflect the soil nutrient supply condition under the influence of the limitations of the current test method. Therefore, the soybean fertilizer which has the advantages of small fertilizer consumption and high fertilizer application efficiency, can promote the yield and income increase of soybeans and improve the pest and disease resistance of soybeans is urgently needed to be developed to make up for the defects of the prior art.
