Abstract
The invention discloses a fine fertilizer application method for flue-cured tobaccos K326. Fine fertilizer application for the flue-cured tobaccos K326 is realized by measuring the alkali-hydrolyzale nitrogen content, the effective phosphorous content and the effective potassium content, calculating the using amount of nitrogen, and then calculating the using amount of phosphorous and the using amount of potassium according to a fertilizer application ratio to finally obtain the amount of nitrogen, phosphorous and potassium fertilizers by a base fertilizer and topdressing combination mode, so that a certain yield of high-quality tobaccos can be obtained. According to the fine fertilizer application method, the most economic fertilizer application amount can be calculated, so that loss of redundant nutrients can be reduced, and the cost can be lowered to a certain extent; on the premise that the yield and the quality of the flue-cured tobaccos K326 are not affected, a requirement on the growth of the flue-cured tobaccos K326 is met under the least using amount of nitrogen, phosphorous and potassium. The tobaccos obtained by the method provided by the invention are high in quality; chemical components in the tobaccos are coordinated; the flue-cured tobaccos are fresh in color, mesophyll tissues are dense, leaves are high in toughness, the oil content is large, and requirements of a cigarette enterprise can be met.
Description
Technical field
The present invention relates to a kind of meticulous fertilizing method of flue-cured tobacco K326, belong to agricultural technical field of fertilizers.
Background technology
Flue-cured tobacco is the important economic crops of China, the basic material of cigarette industry.Flue-cured tobacco K326 is that cigarette mainly one of is filled a prescription, its growth has the Rules of Nutrition of self and unique quality requirements, in addition flue-cured tobacco K326 planting range expands year by year, various places soil nutrient condition difference is large, if want, obtain the sound tobacco of certain output, the accurate fertilizer practice of flue-cured tobacco K326 is just seemed to particularly important.
The subject matter that flue-cured tobacco K326 fertilising at present exists is that nitrogen phosphorus potassium is uneven, cause yield of tobacco higher, but be difficult to obtain sound tobacco, gained tobacco leaf is more difficult roasting, and the chemical composition in tobacco leaf is inharmonious, make that cured tobacco leaf color and luster is dim, mesophyll tissue loose, blade is thin, oil content is few, poor flexibility, quality of tobacco declines, and is difficult to meet the demand of cigarette enterprise.
Summary of the invention
For problems such as the flue-cured tobacco K326 quality of tobacco of solution prior art plantation gained are poor, chemical composition is inharmonious, the object of the present invention is to provide a kind of meticulous fertilizing method of flue-cured tobacco K326, so that the yield of tobacco of flue-cured tobacco K326 is guaranteed, quality of tobacco meets industrial group's demand, do not affecting under the prerequisite of flue-cured tobacco K326 output and quality, still can just meet with minimum application quantity of nitrogen phosphorus potassium the growth demand of flue-cured tobacco K326 simultaneously.
The present invention be directed to the meticulous fertilizing method of this kind flue-cured tobacco of flue-cured tobacco K326, to obtain certain output sound tobacco.By measuring alkali-hydrolyzable nitrogen content, calculate nitrogen consumption, then according to Application Ratio, calculate phosphorus consumption and potassium application rate, finally obtain the amount of azophoska, the mode that adopts base manure and topdress and combine, realizes the meticulous fertilising of K326 flue-cured tobacco.
Method provided by the invention is concrete through following each step:
(1) the vega topsoil that is 0～30 centimetre to the degree of depth samples, and according to the actual conditions of sampling landform, evenly gets 7～9 points, and the soil that mixes sample point obtains aggregate sample, measures the alkali-hydrolyzable nitrogen content X of aggregate sample;
(2) according to step (1) gained alkali-hydrolyzable nitrogen content X, calculate as follows nitrogen consumption N:
Nitrogen consumption N(Kg/ mu)=suitable critical value of nutrient-X(mg/kg that produces) * 0.15 * correction coefficient
Wherein, correction coefficient is=11.831X
-0.722, the suitable critical value of nutrient that produces is: 15.446 ± 1.6kg/ mu;
(3) according to the flue-cured tobacco K326 Application Ratio of field cigarette, be N:P
