Special biological organic composite coated fertilizer for barley and preparation method of fertilizer

Abstract

The invention discloses a special biological organic composite coated fertilizer for barley. The special biological organic composite coated fertilizer is characterized by being prepared from the following raw materials in parts by weight: 56-60 parts of sawdust, 60-65 parts of wheat bran, 10-12 parts of gypsum, 30-36 parts of flour weevil fecula, 2-4 parts of fulvic acid, 30-35 parts of stonewort, 60-66 parts of rape stalk, 45-47 parts of wheat bran, 56-59 parts of rape seed cake, 18-21 parts of phosphorus pentoxide, 17-20 parts of potassium oxide, 10-14 parts of magnesium oxide, 1-2 parts of ammonium molybdate, 1-2 parts of sodium borate, 29-33 parts of urea, 6-8 parts of EM fungicide, 7-9 parts of soil modifier and proper water. The special biological organic composite coated fertilizer is reasonable in proportioning and comprehensive in nutrient, contains a plurality of microelements, and meets the requirements for barley growth. The soil modifier is added, so that the special biological organic composite coated fertilizer has the effects of increasing effect and promoting nutrient absorption of plants, and is coated with molten urea, so as to form a slow release fertilizer. The slow release fertilizer is significant in effect, the utilization rate of the fertilizer can be improved, the yield and the quality of the barley also can be improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special bio-organic composite coated fertilizer for barley and a preparation method thereof. Background technique [0002] In recent years, in order to pursue high crop yields, growers have used a large amount of inorganic chemical fertilizers. While achieving high yields, the long-term use of chemical fertilizers has caused disadvantages such as reduced fertilizer efficiency, low utilization rate, and soil compaction. Rich in certain nutrients, such as phosphorus, which is fixed in the soil and difficult to be absorbed by crops in the same year, will flow into groundwater with rainwater, causing eutrophication and environmental pollution. It also caused an extreme lack of nutrients in the soil. These medium and trace elements are also essential elements for crop growth. Existing fertilizers cannot satisfy barley to obtain sufficient nutrition during the vegetative growth period. C...
