Mineral nutrient for ginseng and American ginseng and preparation method of mineral nutrient

Abstract

The invention relates to a nutrient fertilizer for growth of crops and particularly relates to a mineral nutrient suitable for cultivating ginseng, American ginseng or other crops and a preparation method of the mineral nutrient. The mineral nutrient is prepared from granulating slag, sulfuric acid, hydrochloric acid, filler and water according to the specified weight percentage. The mineral nutrient disclosed by the invention contains a large amount of elements and trace elements for growing and developing plants and rare elements and can be used for supplementing the nutrition in all rounds and supplementing the trace elements of soil so as to meet the growth requirement of the ginseng. Industrial waste materials are taken as raw materials and are abundant, so that the waste utilization can be realized, the cost of products is reduced and the environment friendliness is facilitated. In the aspect of process, inorganic salts generated by the sulfuric acid and the hydrochloric acid according to the proper mixture ratio can be used for better promoting the growth of plants, so that the utilization rate of the mineral nutrient is greatly increased and the excessively-remarkable effect is obtained; and in addition, the defect of the reduction of the biological activity caused by a single sulfate component and an alkaline reaction and a redox reaction of the soil is avoided. The test result shows that the yield of the ginseng in unit area can be increased by over 15 percent.

Description

[0001] technical field [0002] The invention relates to a crop growth nutrient fertilizer, which is a mineral nutrient mainly suitable for cultivating ginseng and American ginseng and a preparation method. It can also be used for other crops. Background technique [0003] In the prior art, ginseng ( Panax Ginseng C.A.Mey) is a plant of the genus Araliaceae and is a traditional Chinese medicine in my country. Jilin Province is the main production area of ​​ginseng in my country and even in the world. The area and output of cultivated ginseng rank first. The output accounts for more than 85% of the national ginseng output and more than 70% of the world's ginseng output. The ginseng industry is the characteristic of Jilin Province industry, strategic industry, but also a national industry. The "Opinions of the People's Government of Jilin Province on Revitalizing the Ginseng Industry" (Jizhengfa [2010] No. 19 Document) has stated that it is necessary to actively carry out res...

AI Technical Summary

Problems solved by technology

[0016] 1. For a long time, most of the fungicides and insecticides used in ginseng are organochlorine and organophosphorus pesticides. Although the effect is still good, due to the large amount of organochlorine and organophosphorus residues in ginseng, the organochlorine and organophosphorus in ginseng exceed the standard, seriously Affect the quality of ginseng

[0017] 2. The traditional ginseng pesticides are basically sprayed on the leaves. Due to the high air temperature in the season of pesticide use, it is easy to cause leaf burns

[0018] 3. Due to the repeated use of ginseng pesticides, the labor intensity of ginseng farmers is increased, and it is easy to cause personal injury to ginseng farmers

[0019] 4. All kinds of traditional ginseng insecticides are only single-component insecticides, which are only used for the control of ginseng pests, and there are no nutrients that are beneficial to the growth of ginseng

The above raw materials are rich in products and can provide the nutrients needed for ginseng cultivation, but their combination as ginseng fertilizer or nutrients has not been reported
