Description
Technical field:
The present invention relates to a kind of Special compound fertilizer for tobacco, belong to tobacco fertilizer field.
Background technology:
Special compound fertilizer for tobacco is the nutritional characteristic according to tobacco and requirement and the fertilizer researched and developed, it is possible to meet the basic nutrition requirement of development of flue-cured tobacco. At present, fertilizer special for tobacco has achieved subregion formula, take into account the basal conditions of the characteristic sum soil fertility that various places tobacco growing is grown, planted in different ecological areas tobacco can have been met to the demand of nutrient form, kind and quantity, and meet tobacco different growing to the application technique requirement of different fertilizer.
Nutrient requirement characteristics is that demand is big in earlier stage by tobacco, later stage demand is few, and existing Special compound fertilizer for tobacco due to stopping composition content higher, cause fertilizer solubility property poor, use rear nutrient can not discharge fast, it is difficult to meet cigarette strain earlier growth to the heavy demand of nutrient, causes the cigarette strain can not early growth and quick tiller; And cigarette strain grow the later stage need de-fertile time, nutrient in composite fertilizer does not also discharge complete, cause cigarette strain late growing stage excessively prosperous, even form black sudden and violent cigarette, normally can not be fallen Huang, increase baking difficulty, thus seriously affect yield of tobacco, quality and better-than-average cigarette rate, and then affect the lifting of tobacco grower's income and tobacco leaf degree structure. Therefore, improvement Special compound fertilizer for tobacco formula, effectively improves solvability and the utilization ratio of fertilizer, makes fertilizer use rear nutrient supply and grows with cigarette strain and matched by nutrient demand, to reducing leaf tobacco production cost, it is to increase yield of tobacco quality is significant.
Summary of the invention
The present invention is by reducing the content of granulation filler, it is to increase npk nutrient total content in fertilizer, reaches the object improved composite fertilizer's solvability, improve utilization rate of fertilizer. Special compound fertilizer for tobacco formula of the present invention, it is specially and it is made up of each component of following weight part: each components by weight is ammonium nitrate phosphorus: monoammonium phosphate: saltpetre: potassium sulfate: Repone K: borax: filler=13.7��24.5:25.0��32.5:8��16:27.8��37:4:1��2:0.8��1.9, mix after adding granulation filler, adopt traditional method granulation. Different according to nitrogen phosphoris and potassium fertilizer ratio in the finished product, each components by weight can be floated in above-mentioned scope.
The production method of Special compound fertilizer for tobacco of the present invention, after being mixed according to certain weight ratio by each raw material, adopts traditional method granulation.
Described granulation filler is white clay, diatomite etc.
Described improvement Special compound fertilizer for tobacco, N P and K total nutrient content 45%��50%, improves 5��10 percentage points than existing Special compound fertilizer for tobacco, and nitric nitrogen accounts for total nitrogen content and is more than or equal to 35%.
Described nitrogen phosphoris and potassium fertilizer ratio is N:P2O5: K2O=1:1��1.5:2��3, wherein nitrogen element provides primarily of ammonium nitrate, ammonium nitrate phosphorus, monoammonium phosphate, saltpetre, in final finished, nitric nitrogen accounts for total nitrogen content and is not less than 35%, and phosphorus element provides primarily of ammonium nitrate phosphorus, monoammonium phosphate, and potassium element provides primarily of saltpetre, potassium sulfate and Repone K.
The present invention is by reducing the content of granulation filler, the solvability of Special compound fertilizer for tobacco can be significantly improved under the prerequisite not reducing intensity, land for growing field crops result of use shows: Special compound fertilizer for tobacco provided by the invention, its nutrient release rate relatively conventional formulation significantly promote, nutrient demand curve one is caused fat by nutrient release curve and cigarette strain more, and material utilization ratio is higher.
Useful effect
Special compound fertilizer for tobacco of the present invention and the contrast of existing Special compound fertilizer for tobacco, its fertilizer solvability strengthens greatly, nutrient element releasing rule research in field shows, uses the supply of rear fertilizer nutrient and grows with cigarette strain and matched by nutrient demand, and utilization rate of fertilizer significantly promotes. Using rear cigarette strain land for growing field crops economical character obviously to improve, cured tobacco leaf yield and quality obviously promotes.
