Abstract
The present invention discloses compound fertilizer special and the fertilizing method thereof of a kind of Zimbabwe flue-cured tobacco KRK26, and in described compound fertilizer, the part by weight of N P and K is 7.5-8.5:9.5-10.5:31-33. The compound fertilizer of the present invention can improve the ratio of first-class Zimbabwe flue-cured tobacco KRK26, improve waist leaf length and wide and improve the ability of anti-balck shank.
Description
Technical field
The invention belongs to agricultural technology field, specifically, the present invention relates to the compound fertilizer special of Zimbabwe flue-cured tobacco KRK26 and fertilizing method thereof.
Background technology
Flue-cured tobacco KRK26 is provided by tobacco research institute of Zimbabwe (Kutasaga) for 2001. By the sterile hybrid of MSk326 and RW (strain of anti-angular leaf spot No. 1 microspecies and root knot nematode disease) selection cross. Breediness: KRK26 is a middle-late ripening variety, ripe speed is balanced, and yield potential is medium to high, is produced quality of tobacco good, ripe particle is good, and lemon yellow tobacco leaf is more than KM10's (Kutasaga1984 granting) and KE1 (Kutasaga1968 granting). Kind well developed root system, drought resistance is good. KRK26 is good from seedling stage to field period general performance, 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, and cigarette factory is 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 planting. At present, in traditional cropping pattern tobacco grower because of lack science guidance, produce on exist fertilizer type collocation and the irrational phenomenon of nutrient formula, show as part peasant household on flue-cured tobacco, still use urea and nitrogen is used too much, potassium use deficiency etc. Tobacco grower blindly uses chemical fertilizer. and the irrational phenomenon of nutrient formula not only reduces utilization rate of fertilizer, add fertilizer cost, also the output and quality of tobacco leaf being caused disadvantageous impact, 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 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 the fertilizer field experiments of 2 years by a definite date according to soil testing result, KRK26 regulation of fertilizer requirement, soil supplying nutrient capability etc., studies out the N P and K 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, and after adopting the composite fertilizer of the present invention, the overall well-grown of cigarette strain, disease resistance is strong, and especially anti-balck shank, sickness rate reduces 3.5%-6.97%.Every economical character value is excellent, and its middle part of the side leaf length and width adds 9.53-15.19% and 3.33-6.45% respectively. Tobacco leaf visual appearance after baking is good, and yield and output value increases, and first-class cigarette ratio improves 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 compound fertilizer, the ratio of N P and K is 7.5-8.5: 9.5-10.5: 31-33, it is preferable that be 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, potter's clay and kaolin, diatomite and/or fluorite.
In another preferred embodiment of the present invention, described compound fertile by pre-broken, be uniformly mixed, fragmentation, drum granulating, drying kiln dry granulating, cooling kiln cooling, sieve and packaging prepares.
The present invention also relates to the fertilizing method of a kind of Zimbabwe flue-cured tobacco KRK26 on the other hand, it is characterised in that transplant the stage, and every mu of above-mentioned compound using 40-50kg is fertile; Then in the stage of topdressing, the saltpetre 9-11kg and potassium sulfate 9-11kg that topdresses is used for every mu.
The present invention also relates on the other hand that above-mentioned compound is fertile or the purposes of fertilizing method, and described is improves the ratio of first-class Zimbabwe flue-cured tobacco KRK26, raising waist leaf length and width and/or improve the ability of anti-balck shank.
Through lab analysis, adopting the compound of the present invention fertile, tobacco leaf internal chemical composition is coordinated, total nitrogen, nicotine, total reducing sugar, reducing sugar, cigarette potassium, sugar alkali when nitrogen base than all in relatively optimum range. Wherein potassium content of tobacco leaf brings up to more than 2%, and nicotine reduces about 9.27-18.77%.
