Dedicated organic inorganic compound fertilizer for K236, Yunnan tobacco, and NC series flue-cured tobacco

Abstract

The invention provides a dedicated organic inorganic compound fertilizer for K236, Yunnan tobacco, and NC series flue-cured tobacco. The fertilizer is prepared by the following steps: evenly mixing the following components in parts by weight: 17 to 57 parts of thoroughly decomposed rapeseed oil cake, 0 to 10 parts of monoammonium phosphate, 3 to 13 parts of diammonium phosphate, 18 to 24 parts of potassium sulfate, 13 to 19 parts of potassium nitrate, 3 to 4 parts of potassium chloride, 0.5 to 1 part of anhydrous borax, 0.5 to 1 part of zinc sulfate, 0.5 to 1 part of magnesium sulfate, 1 to 3 parts of amino acid, 3 to 7 parts of potassium humate, fully grinding the mixture, and completely sieving the grinded mixture so as to obtain the fertilizer. The compound fertilizer can be used for the K326/Yunnan tobacco series and the NC series flue-cured tobacco. The water solubility of the fertilizer is good. The fertilizer can better coordinate the nutrients in soil, promotes the growth of tobacco plant in the early stage, and assists the timely maturity and yellowing in the later stage. Furthermore, the fertilizer utilization rate is improved. The tobacco leaf is easy for baking and the quality of tobacco leaf is improved. The fertilizer is easy to use for farmers, thus the workload for farmers is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer formulations, and in particular relates to an organic-inorganic compound fertilizer (containing nitrogen in two forms of organic and inorganic) specially used for K326, Yunyan and NC series flue-cured tobacco. Background technique [0002] K326, Yunyan 87, Yunyan 97, Yunyan 99, etc. are flue-cured tobacco varieties with large planting areas in my country's flue-cured tobacco production, while NC102, NC71, NC297, etc. are varieties that have entered my country's flue-cured tobacco production for only a few years. In the current production, many places reflect that the tobacco plants of the above-mentioned varieties "do not grow in ponds or grow slowly" in the early stage, but "mature late and yellow slowly" in the later stage, which has an adverse effect on the formation of good quality tobacco leaves. Field experiments have found that the reason for the above phenomenon has a lot to do with the...
