Description

A kind of special water-retaining type rhizosphere fertilizer of flue-cured tobacco seedling-cultivating and preparation method thereof
Technical field
The present invention relates to tobacco planting and technical field of fertilizers, specifically a kind of special water-retaining type rhizosphere fertilizer of flue-cured tobacco seedling-cultivating And preparation method thereof.
Background technology
The fertilizer of crop rhizosphere, referred to as rhizosphere fertilizer can directly be imposed on.Rhizosphere fertilizer product is concentrated mainly on woods at present In terms of wood, fruit tree, vegetables, for example the main component of the rhizosphere fertilizer for palm of Zhengzhou University is ureaformaldehyde, ammonium magnesium phosphate, melts Melt phosphorus potassium etc..And it is directed to the water-retaining type rhizosphere fertilizer of the flue-cured tobacco root external spraying seedling-raising technique of Tobacco Seedlings phase nutritional need at present also It has not been reported.
Can be used as tobacco seedling rhizosphere fertilizer at present is water-soluble nitrogen, phosphorus, potassium and secondary and micro-element fertilizers, but the fertilizer Salt index is all very high, need it is soluble in water, be made into the lower nutrient solution of concentration for tobacco root absorb, still fall within water planting Technical system.The hydroponic culture systems and the single fertilization mist training system of the present invention are that have essential distinction.
Flue-cured tobacco root external spraying seedling-raising technique is different from floating seedling cultivation of fire-cured tobacco technology, which casts out nutriculture, Moisture and rhizosphere single fertilization technology are supplied using root external spraying, but the salt index of traditional chemical fertilizer is higher, if one Secondary property imposes in the seedling medium of flue-cured tobacco spraying nursery, will can cause to burn kind, burn seedlings problem;If using foliage-spray side Formula, concentration of fertilizer height then burn leaf, and concentration is low, need to increase fertilizer application frequency, increase cost of labor, and flue-cured tobacco seedling stage liquid manure Demand is often asynchronous, if liquid manure supplies the physiological activity for having interfered with blade simultaneously, to influence tobacco growth.
Invention content
The purpose of the present invention is to provide special water-retaining type rhizosphere fertilizer of a kind of flue-cured tobacco seedling-cultivating and preparation method thereof, are flue-cured tobacco Root external spraying nursery provides a kind of special water-retaining type rhizosphere fertilizer of flue-cured tobacco seedling-cultivating of the single fertilization of suitable flue-cured tobacco seedling-cultivating, to It realizes that flue-cured tobacco root external spraying seedling-raising technique replaces traditional floating seedlings technology, overcomes traditional floating seedlings by low temperature and less sunshine pair The influence of seedling quality;And the rhizosphere fertilizer of the application present invention, the labour costs of flue-cured tobacco seedling-cultivating can be reduced and improve fertilizer Utilization rate.
To achieve the above object, the present invention provides the following technical solutions:
A kind of special water-retaining type rhizosphere fertilizer of flue-cured tobacco seedling-cultivating, is grouped as by the group of following mass component:Isobutanediurea 20~40 Part, 10~20 parts of potassium magnesium phosphate, 20~30 parts of potassium nitrate, 10~30 parts of potassium humate organic-inorganic water-retaining agent, borax 0.5~5 Part, 0.5~5 part of zinc oxide, 0.5~5 part of cupric sulfate pentahydrate, 0.5~5 part of ferrous sulfate, 0.5~5 part of manganese sulfate, ammonium molybdate 0.5~1 part, 5~20 parts of agstone, 10~20 parts of chitosan, 0.5~1 part of promoter.
As a further solution of the present invention:
The special water-retaining type rhizosphere fertilizer of flue-cured tobacco seedling-cultivating, is grouped as by the group of following mass component:Isobutanediurea 25~35 Part, 12~18 parts of potassium magnesium phosphate, 22~28 parts of potassium nitrate, 15~25 parts of potassium humate organic-inorganic water-retaining agent, 2~4 parts of borax, 2~4 parts of zinc oxide, 2~4 parts of cupric sulfate pentahydrate, 2~4 parts of ferrous sulfate, 2~4 parts of manganese sulfate, 0.6~0.9 part of ammonium molybdate, stone 10~15 parts of limestone flour, 12~18 parts of chitosan, 2~4 parts of promoter.
As further scheme of the invention:
