Abstract
The invention discloses special compound fertilizer for Zimbabwe flue-cured tobacco KRK26 and a fertilization method thereof. The weight ratio of nitrogen, phosphorus and potassium in the compound fertilizer is (7.5-8.5): (9.5-10.5): (31-33). The compound fertilizer disclosed by the invention has the advantages that the proportion of high-quality Zimbabwe flue-cured tobacco KRK26 can be increased, the length and width of lumbar leaves are improved, and the blackleg resistance is improved.
Description
Technical field
The invention belongs to agricultural technology field, particularly, the present invention relates to compound fertilizer special and the fertilizing method thereof of Zimbabwe flue-cured tobacco KRK26.
Background technology
Flue-cured tobacco KRK26 Shi You Zimbabwe tobacco research institute (Kutasaga) provides calendar year 2001.Sterile hybrid by MS k326 and RW (strain of No. 1 microspecies of anti-angular leaf spot and root knot nematode disease) selection cross.Breediness: KRK26 is a middle-late ripening variety, ripe speed is balanced, and yield potential is medium paramount, the quality of tobacco of producing good, ripe particle is good, and lemon yellow tobacco leaf is more than KM10 (Kutasaga1984 granting) and KE1's (Kutasaga1968 granting).Kind well developed root system, drought resistance is good.KRK26 is good to field period general performance from seedling stage, and growing way is strong, and growth is neat, and disease resistance is strong, and field growing way is delicate and pretty, and output, the output value are higher, and tobacco grower likes ，Yan factory acceptant.
In recent years, along with developing rapidly of cured tobacco production, some problems also highlight day by day, and as large-scale degree is low, breed structure is single, and potassium content of tobacco leaf is lower, and planting system is science etc. not to the utmost, wherein outstanding with the problem of fertilization in plantation.At present,, there is fertilizer type collocation and the irrational phenomenon of nutrient proportioning in for want of guidance of science of tobacco grower in traditional cropping pattern on producing, and shows as that part peasant household still uses urea on flue-cured tobacco and nitrogen is used too much, potassium is used deficiency etc.Tobacco grower blindly uses chemical fertilizer. and the irrational phenomenon of nutrient proportioning has not only reduced utilization rate of fertilizer, increased fertilizer cost, also the output and quality of tobacco leaf has been caused to adverse influence, more seriously too much chemical fertilizer produces adverse consequences (water pollution, pollution of agricultural products and Greenhouse effect etc.) to the environment of our existence.
It is reported, the existing special-purpose nitrogen-phosphorus-potassium compound fertilizer for flue-cured tobacco of various places tobacco company, but also there is no the specific NpK complex fertilizer for KRK26.The present invention has carried out two-year fertilizer field experiments according to soil testing result, KRK26 regulation of fertilizer requirement, soil supplying nutrient capability etc., works out the nitrogen phosphorus potassium compound fertilizer special of a kind of KRK26.
Summary of the invention
One aspect of the present invention relates to compound fertilizer special and the fertilizing method thereof of a kind of Zimbabwe flue-cured tobacco KRK26, adopts after composite fertilizer of the present invention, and the whole well-grown of cigarette strain, disease resistance is strong, especially anti-balck shank, sickness rate has reduced 3.5%-6.97%.Every economical character value is excellent, and its middle part of the side leaf length and width has increased respectively 9.53-15.19% and 3.33-6.45%.Tobacco leaf visual appearance after baking is good, and yield and output value increases, and first-class cigarette ratio has improved 6.98-11.15%.
One aspect of the present invention relates to the compound fertilizer special of a kind of Zimbabwe flue-cured tobacco KRK26, and in described Chemical Mixed Fertilizer, the ratio of nitrogen phosphorus potassium is 7.5-8.5:9.5-10.5:31-33, preferably 8:10:32.
In a preferred embodiment of the present invention, described compound fertilizer special comprises the component of following weight part: ammonium nitrate: 12-14, diammonium phosphate: 37-39, potassium sulfate: 48-50.
In a preferred embodiment of the present invention, described compound fertilizer special does not comprise urea; Preferably, described compound fertilizer special does not comprise other component except wilkinite, wilkinite, potter's clay and kaolin, diatomite and/or fluorite.
In another preferred embodiment of the present invention, described Chemical Mixed Fertilizer by precrushing, be uniformly mixed, granulating is dried in fragmentation, drum granulating, drying kiln, cooling kiln is cooling, screening and packing prepare.
The present invention also relates to the fertilizing method of a kind of Zimbabwe flue-cured tobacco KRK26 on the other hand, it is characterized in that the transplanting stage, every mu of above-mentioned Chemical Mixed Fertilizer of using 40-50kg; Then in the stage of topdressing, use topdress saltpetre 9-11kg and potassium sulfate 9-11kg for every mu.
The present invention also relates to the purposes of above-mentioned Chemical Mixed Fertilizer or fertilizing method on the other hand, described is improve first-class Zimbabwe flue-cured tobacco KRK26 ratio, to improve waist leaf long and wide and/or improve the ability of anti-balck shank.
Through lab analysis, adopt Chemical Mixed Fertilizer of the present invention, the inner chemical composition of tobacco leaf is coordinated, and total nitrogen, nicotine, total reducing sugar, reducing sugar, cigarette potassium, sugared alkali when nitrogen base compare all in compared with optimum range.Wherein potassium content of tobacco leaf is brought up to more than 2%, and nicotine has reduced 9.27-18.77% left and right.
