Description
Technical field
The present invention relates to the determination methods of high-quality tobacco production fertilizer applications, belong to flue-cured tobacco cultivation technical field.
Background technique
Flue-cured tobacco is one of Important Economic crop of Panzhihua City, is the main economic source of local farmers.In the kind of flue-cured tobacco
During plant, fertilizer plays an important role to the growth and development of flue-cured tobacco, and the fertilizer applications of optimization can promote the life of high-quality tobacco
It produces, environmental pollution caused by long-term excessive application chemical fertilizer is reduced, to realize the sustainable development of cured tobacco production.
Nitrogen, phosphorus, potash fertilizer are three big nutrients of plant growth.Reasonable Combined Application of NPK can promote the increasing of flue-cured tobacco
Production increases income, and fertilising is insufficient or fertilising surplus will affect the yield and quality of flue-cured tobacco, and causes the pollution of environment, influences to give birth to
State sustainable development.The cigarette area peasant of Panzhihua City plant at present relies primarily on empiric fertilization, and experts and scholars are to Panzhihua City flue-cured tobacco
The research of best fertilizer applications is also less.Chen Yi is strong etc. to establish the Fertilizer Application of Tobacco model based on soil fertility contribution rate, Chen Wei
The tobacco high-yield fertilization model having studied based on target output such as strong, Zhang Wenming etc. is established roasting by " 3414 " fertilizer test
Cigarette high-yield fertilization model.These Fertilization Models, which are substantially based on crop yield or the output value are standard, judges the good of fertilization effect
Whether bad.But the superiority and inferiority of flue cured tobacco quality can not be only judged from yield or the output value.
And currently, tobacco business evaluates the variation of the superiority and inferiority and style of quality of tobacco mainly by the sense organ of people, sense organ is commented
Surely the physiology and mental condition for relying primarily on people are an exquisite technology in itself.In a sense, due to by experience,
The influence of the subjective factors such as mood, subjective appreciation method result have subjective factor.
Therefore, it is badly in need of one kind and flue cured tobacco quality is evaluated based on Chemical Compositions of Flue-cured Tobacco, so that it is determined that high-quality tobacco production fertilising
The method of scheme.
Summary of the invention
