Abstract

The invention relates to a fertilizing method in flue-cured tobacco production, and belongs to the technical field of flue-cured tobacco fertilization. In the method, before a flue-cured tobacco sprout is cultured, the total quantity of a fertilizer is determined by measuring earthwork according to the required height of a field ditch, and 95 percent of the fertilizer serving as a base fertilizer based on the total quantity of the fertilizer is fertilized into the field ditch twice; and after the flue-cured tobacco sprout is cultured, the fertilizer in an amount which accounts for 5 percent of the total quantity of the fertilizer is fertilized in the field ditch, which is 10 to 15cm deviated from the center of the sprout. The method comprises the specific steps of: a, performing single fertilization on the upper side of the field ditch by using 57 percent of the fertilizer serving as a first base fertilizer based on the total quantity of the fertilizer which is determined by measuring the earthwork according to the required height of the field ditch; b, after fertilizing the field ditch by using the first base fertilizer, clearing the field ditch to 25cm on the upper side of the field ditch, and performing single fertilization on the upper side of the field ditch by using 38 percent of the fertilizer serving as a second base fertilizer based on the total quantity of the fertilizer; and c, covering 5 to 8cm soil on the surface which is fertilized by the second base fertilizer, controlling the height of the field ditch to be 40cm, and allowing two layers of fertilizers to be arranged vertically in the center of a ridge. The method has the advantages of uniform fertilization, long time for fertility, fast maturity of a tobacco plant, and capability of effectively preventing the fertilizer deficiency and reducing the labor intensity.

Description

Fertilizing method in a kind of tobacco planting

Technical field:

The present invention relates to the fertilizing method in a kind of tobacco planting, belong to flue-cured tobacco fertilizer practice field.

Background technology:

Tobacco is the important economic crops of China, and in many areas, tobacco planting is the most important revenue sources of the local common people.Quality of tobacco is subjected to the influence such as factors such as weather, cultivation steps, and along with tobacco leaf standardized production and modern tobacco agriculture construction, the leaf tobacco production Technology Need carries out a series of perfect.Precisely efficient fertilising becomes the key technology that improves yield and quality.At present, flue-cured tobacco base manure four-function mode mainly contains wall scroll and executes, spreads manuer in holes and locate three kinds of circulating application.Wall scroll is executed easy to operate, but fertile distance of positions cigarette strain root system is far away, and absorb few early stage, is unfavorable for that the cigarette strain early goes out fast sending out, and fertile position is low easily causes loss; The fertility of spreading manuer in holes is concentrated, and help the cigarette strain and early go out fast sending out, but because the fertilizer undue concentration is prone to the burning seedling, the amount of labour used is big, constant mechanical work; Locating ring is executed the amount of labour used, fertile position is far away, both has been unfavorable for cigarette strain early growth and quick tiller, and has easily caused fertilizer loss, more inconvenient mechanical work.Rapid propelling along with modern tobacco agriculture.Mechanization is popularized rapidly and is improved, the continuous maturation of precisely efficient fertilizer practice, and innovation cured tobacco production technical system, satisfying the modern tobacco agriculture needs becomes the task of top priority.

By literature search, do not see the open report identical with the present invention.

Summary of the invention:

The objective of the invention is to overcome the deficiency of prior art, and a kind of favourable cigarette strain early growth and quick tiller is provided, reduce the fertilising link, be convenient to mechanized, the fertilizing method in the tobacco planting of raising fertilizer service efficiency.

The present invention proposes on the basis of big quantity research.Discover in a large number: in the tobacco planting process, the growing height of cigarette strain all has certain rules.The present invention generates the rule of height according to the cigarette strain, the high science height of moisture in the soil is proposed, before not cultivating, divide the flue-cured tobacco seedling secondary to apply in the moisture in the soil as base manure 95% minute of total fertilization amount in the plantation, not only use time for fertilizer long, and omitted the operation of fertilising in the growth of cigarette strain process, be more conducive to cigarette strain growth.

Fertilizing method in a kind of tobacco planting of the present invention is: before the flue-cured tobacco seedling is not cultivated, according to the high cubic metre of earth total fertilization amount of determining of surveying of required moisture in the soil, get 95% minute of total fertilization amount and divide secondary to apply in the moisture in the soil as base manure; After treating the cultivation of flue-cured tobacco seedling, departing from the fertilizer that 10-15cm place, seedling center applies total amount 5%; Concrete steps are as follows:

A. according to the high cubic metre of earth total fertilization amount of determining of surveying of required moisture in the soil, get total fertilization amount 57% as the first time base manure above moisture in the soil, carry out wall scroll and execute;

B. again the first time base manure execute the back moisture in the soil above manage moisture in the soil and reach 25cm, get total fertilization amount 38% as the second time base manure above moisture in the soil, carry out wall scroll and execute;

C. executing earthing 5-8cm on the face of base manure for the second time then, control moisture in the soil height is 40cm, and two-layer fertilizer all is in vertical distribution in ridge body central authorities.

The same prior art of wall scroll fertilising process in the inventive method.

The present invention compared with prior art has the following advantages:

1, fertility is evenly moderate, helps cigarette strain early growth and quick tiller;

2, time for fertilizer long, help cigarette strain normal mature;

3, be easy to put into practice mechanical work, effectively reduce fertilizer loss;

4, minimizing is topdressed and is beaten pool operation, reduces labour intensity.

Embodiment:

Below in conjunction with accompanying drawing the inventive method is described in further detail.

Fertilizing method in a kind of tobacco planting of the present invention is:

1, before the flue-cured tobacco seedling is not cultivated, according to a conventional method according to a required reason moisture in the soil and a survey cubic metre of earth total fertilization amount of determining;

2. get total fertilization amount 57% as the first time base manure above moisture in the soil, carry out machinery or artificial wall scroll is executed;

3, again the first time base manure execute the back moisture in the soil above manage moisture in the soil and reach 25cm, get total fertilization amount 38% as the second time base manure above moisture in the soil, carry out machinery or artificial wall scroll is executed;

4. executing on the face of base manure for the second time earthing 5 or 6.5 or 8cm then, control moisture in the soil height is 40cm, and two-layer fertilizer all is in vertical distribution in ridge body central authorities;

5, with after the seedling cultivation, departing from the fertilizer that seedling center 10 or 15cm place apply total amount 5%.

The inventive method is used and shown: not only fertility is even, time for fertilizer long, cigarette strain growth and maturity are fast; Effectively prevent fertilizer loss, reduced labour intensity.
