Problems solved by technology

However, the production, storage and use of biological fertilizers are very strict. If they are not handled properly, it is easy to bring harmful bacteria; or poor storage management leads to the loss of the activity of biological fertilizers.
This not only increases the fertilizer cost, but also limits the promotion and application of the fertilizer
[0008] Therefore, it is of great significance to develop a special water-soluble fertilizer that conforms to the law of nutrient absorption in the growth cycle of American ginseng, and can solve the problems of nitrogen volatile loss and phosphorus element being easily fixed by the soil.

Abstract

The invention relates to special slow-released water-soluble fertilizer for american ginseng and a preparation method thereof. The special fertilizer is prepared from urea, potassium chloride, diammonium phosphate, potassium sulphate, superphosphate, magnesium sulfate, ferric sulfate, zinc sulfate, manganese sulfate, humic acid and inorganic gel particles. The invention further relates to a preparation method of the special slow-released water-soluble fertilizer for american ginseng. According to the special fertilizer, the nitrogen phosphorus and potassium nutrients are reasonably mixed according to the characteristic of demand of growth of american ginseng on fertilizer; medium trace elements such as sulphur, magnesium and iron required by american ginseng in the growth period are added to promote the growth of american ginseng as well as improve the disease resistance of american ginseng; in addition, the nutrients of the special slow-released water-soluble fertilizer for american ginseng is slowly released, which meets the nutrient absorbing rules of american ginseng in the growth cycle, and the effects of increasing the yield and improving the quality of american ginseng are achieved; meanwhile, the utilization rate of water-soluble fertilizer property is increased.

Description

technical field [0001] The invention relates to a special slow-release water-soluble fertilizer for American ginseng and a preparation method thereof. More specifically, the invention relates to a slow-release special water-soluble fertilizer for American ginseng and a preparation method thereof, belonging to the field of special water-soluble fertilizers. Background technique [0002] American ginseng is a perennial plant of the Araliaceae genus Panax (Panax L.), which is a plant of the same genus and different species from Homo, also known as American ginseng (Panax Quinquefolium L.), native to Greater Quebec, Canada and Wisconsin, USA . American ginseng is a valuable health product, which has many benign regulatory effects on the body. The introduction of American ginseng to our country began in 1948. It was introduced and cultivated from Canada by Jiangxi Lushan Botanical Garden. It was not until 1975 that there was a planned large-scale introduction and cultivation. To...
