Abstract
A kind of flue-cured tobacco soil testing and formulated fertilization method, is sampled to topsoil, and fast automatic test is carried out to the nitrogen of soil sample, phosphorus, potassium content, acid-base value, organic matter with soil nutrient automatic analyzer.Amount of nitrogen is determined according to amount of the soil sample containing available nitrogen, is determined with the phosphorus content in fertilizer according to the amount of amount of nitrogen and soil sample containing available phosphorus, determined with the potassium content in fertilizer according to the amount of amount of nitrogen and soil sample containing available potassium.Prepare fertilizer.It is combined using base manure and topdressing, base manure is made with 2/3 no less than whole doses, remaining topdresses, and original topdressing amount is adjusted according to actual conditions.Applied fertilizer using ring-type, it is 10 ~ 15 centimetres with cigarette strain distance to allow fertilizer.Soil nutrient automatic analyzer is prior art, commercially available product.Can not only allow Fertilizer Application of Tobacco scientific combination physics and chemistry, and as a result of soil nutrient automatic analyzer, facility simple to operate is capable of achieving fast automatic test, time saving to save trouble.
Description
Technical field
The invention belongs to agricultural technology field, and in particular to a kind of flue-cured tobacco soil testing and formulated fertilization method.
Background technology
The subject matter that current Fertilizer Application of Tobacco is present is nutritional imbalance, and the light phosphorus potassium deficiency of diazonium, vega soil fertility occurs
Downward trend, this and Fertilizer Application of Tobacco are not scientific and reasonable closely related.
Flue-cured tobacco fertilization compositions based on earth measurement is a new technology for the scientific and reasonable fertilising of flue-cured tobacco, the survey of its foundation vega soil fertility
Result is determined, it is determined that specific fertilizer formula, dose and fertilizing method.
The content of the invention
According to the deficiencies in the prior art, there is provided a kind of flue-cured tobacco soil testing and formulated fertilization method, the method makes tobacco be sent out in growth
Necessary nutrient obtains supply that is complete, balanced, coordinating during educating.
The present invention is realized by following technical scheme：
A kind of flue-cured tobacco soil testing and formulated fertilization method, including it is following rapid：
（1）, the topsoil of the centimeters of vega depth 18~25 is sampled, sampling block area is 0.5~4 mu, is taken
Sampling point is 5~12 and to be uniformly distributed, and the soil sample that each sample point takes out is well mixed, and uses quartering division, retain 400~
700 grams, make a record, soil sample loads container after air-drying or drying and preserves；
（2）, by the requirement of automatic analyzer pre-treatment is carried out to soil sample, using soil nutrient automatic analyzer to the nitrogen of soil sample,
Phosphorus, potassium content, acid-base value, organic matter carry out fast automatic test；
（3）, amount of nitrogen determined by following scope containing the amount of available nitrogen according to soil sample；
（4）, determined with the phosphorus content in fertilizer according to the amount of amount of nitrogen and soil sample containing available phosphorus；N：P2O5=1：1.2~1：1.5, soil
Phosphorus application amount should be more when sample amount containing available phosphorus is relatively low, and phosphorus application amount should be less when soil sample amount containing available phosphorus is higher；
（5）, determined with the potassium content in fertilizer according to the amount of amount of nitrogen and soil sample containing available potassium；
(6), fertilizer is prepared according to the above results；
Preferably, it is combined using base manure and topdressing, base manure is made with 2/3 no less than whole doses, remaining topdresses, and
Appearance, soil and climatic condition according to field cigarette strain, adjust original topdressing amount；Applied fertilizer using ring-type, allow fertilizer and cigarette strain
Distance is 10~18 centimetres, in order to avoid burn seedlings.
Beneficial effect of the present invention：
The present invention can not only allow Fertilizer Application of Tobacco scientific combination physics and chemistry, and as a result of soil nutrient automatic analyzer, operation
It is simple and easy, fast automatic test is capable of achieving, it is time saving to save trouble.
Specific embodiment
Embodiment：
Vega is mountain red earth, and kind is the big gold dollar of safflower.Sampling block area is 1 mu, and sample point 8 is uniformly distributed.To depth
Spend the soil sample of 20 centimeters.The soil sample that 8 sampling points take out is well mixed, quartering division is used, retains 500 grams, carried out
Record, soil sample loads container after air-drying and preserves.After pre-treatment being carried out to soil sample.Soil sample mg/kg containing available nitrogen 45, applies nitrogen
Amount is set to 10,000 grams/acre；The fixed phosphorus content with fertilizer is 7,000 grams/acre；Soil sample mg/kg containing available potassium 123, it is fixed with fertilizer
Potassium content（K2O）It is 16,000 grams/acre.Fertilizer is prepared according to the above results.It is combined using base manure and topdressing, uses whole fertilisings
Base manure is made in the 3/5 of amount, and remaining topdresses.Applied fertilizer using ring-type, it is 10~15 centimetres with cigarette strain distance to allow fertilizer.Tobacco leaf is realized
High yield and high quality.
Although the present invention is disclosed above with preferred embodiment, so it is not limited to the present invention.Skill belonging to of the invention
Has usually intellectual in art field, without departing from the spirit and scope of the present invention, when can be used for a variety of modifications and variations.Cause
This, protection scope of the present invention ought be defined depending on those as defined in claim.
