The invention belongs to the field of crop fertilizer, in particular relates to synergistic ecological fertilizer special for radix astragali and a preparation method of the synergistic ecological fertilizer. The synergistic ecological fertilizer special for the radix astragali is prepared from the following components by a certain weight proportion: sorghum halepense stalks, Chinese pennisetum, palm leaves, wormcast, a starter culture, charcoal, amino-bentonite, phosphorite powder, urea, potassium sulphate, microelements, fructo-oligosaccharide and jasmonic acid methyl ester. The ecological fertilized provided by the invention takes natural organic matters as main materials, green and environmental protection is achieved, crops can be promoted to rapidly grow, meanwhile the fructo-oligosaccharide and the jasmonic acid methyl ester are added in the mixed fertilizer, a secondary metabolism process of the radix astragali is promoted, the content of astragalus polysaccharide is increased, and the quality of the radix astragali is improved. The synergistic ecological fertilizer is reasonable in formula, and overall and balanced in nutrition, the utilization rate of fertilizer effect can be obviously improved, the yield and quality of the radix astragali can be greatly improved, the soil environment can be improved by long-term application of the ecological fertilizer, the capacities of fertilizer conservation and fertilizer supply and the buffer capacity of the soil can be enhanced, the occurrence of damage by disease and insect can be reduced, and the economic benefit of the radix astragali can be improved.

The invention discloses a planting method capable of increasing the yield of Astragalus propinquus Schischkin. The method comprises the steps: ploughing a selected land firstly in autumn before sowing, performing fertilization, performing raking and flattening, performing furrowing and ridging, then treating seeds of Astragalus propinquus Schischkin by using sulfuric acid, covering the seeds withsoil, performing covering after sowing, determining an initial plant spacing and a final plant spacing until a certain height of the seedlings of Astragalus propinquus Schischkin, spraying a plant nutrient solution to the roots of the seedlings of Astragalus propinquus Schischkin so as to increase the yield of Astragalus propinquus Schischkin, loosening the soil after emergence of all the seedlings of Astragalus propinquus Schischkin, performing weeding and fertilization, performing topdressing and watering or water drainage at the flowering stage, controlling diseases, pests and weeds at thesame time, and performing harvest after maturation of Astragalus propinquus Schischkin. According to the method, field management is enhanced, the planting scale is uniform and standard, and meanwhilethe roots of the seedlings of Astragalus propinquus Schischkin are nourished by the plant nutrient solution, so that the yield of Astragalus propinquus Schischkin is improved significantly.
