Abstract
The invention provides a method for producing selenium-enriched tea leaves by endogenous regulation of soil. The acidification degree of the soil is relieved by applying a soil modifier, so that the pH of the soil is increased, and the chemical effectiveness of selenium of the soil is enhanced; by application of substances such as biological organic fertilizer, the microorganism colony structure of the soil at the root of a tea tree is improved, the root growth of the tea tree is promoted, and the root absorption capacity of the tea tree is improved, so that the chemical effective selenium in the soil can be absorbed to form biological effective selenium in the tea tree body, and the aim of producing and developing the selenium-enriched tea leaves can be achieved. After the method is used, the selenium content of the tea leaves is 0.97+/-0.02mg/kg, and the selenium content of common tea leaves without selenium fertilizer is 0.28+/-0.01mg/kg, so that the selenium content of the tea leaves is increased by almost 3 times. According to the method, the selenium fertilizer does not need to be applied extra, so that the safety risk caused by application of inorganic selenium is avoided, and the method is suitable for a large area of acidic selenium-enriched tea garden.
Description
One, technical field
The present invention relates to soil property improvement and element regulation and control field, particularly relate to the method that selenium-enriched tea leaf is produced in the regulation and control of a kind of soil inside source.
Two, technical background
Tealeaves is one of large non-alcoholic drink in the world three, there are some researches show, tea tree is natural selenium-enriched plant, and the selenium in tealeaves mainly exists with the Organic Selenium form being more of value to health, and Se rich tea be proved can Tumor suppression, the concentration significant correlation of selenium in its effect and tea.In view of selenium is human body essential nutrient element, again with health relation and closely, therefore develop high-quality selenium-enriched tea leaf significant.
Tea tree property happiness acid, the suitableeest soil pH of its growth is 5.5, lower than 4.0 or all can suppress the growth of tea tree higher than 6.0.The factor impacts such as the acid rain caused along with weather conditions change, improper fertilization and environmental pollution in recent years, tea garden soil presents acidification trend, and tea garden soil acid intensity is also more and more higher.After tea garden soil acidifying, soil structure is affected, and nutrient availability reduces, and soil microflora is destroyed, thus affects the growth of tea tree.Tea garden soil acidifying on the other hand, soil acidity strengthen the chemical availability being more reduction of Selenium in Soils, affect tea tree to the absorption of Selenium in Soils and utilization, the exploitation of serious restriction selenium-enriched tea leaf and production.
Soil conditioner is also called soil conditioner, is that a class is mainly used in improvement soil property and makes it be more suitable for plant growth, simultaneously can be again the material that plant provides nutrient.The research of Li Daolin shows, soil conditioner can regulate soil acidity or alkalinity, thus provides suitable growing environment for crop; The research of Yang Ni etc. shows, because fused calcium magnesium phosphate alkalescence is comparatively large, tea tree happiness Acidity in addition, thus it as improve tea place pH value adjustment agent list to execute effect be not fine and practical operation time the consumption that enriches can not be excessive; The research of Zhao Yan etc. shows after multiple improved materials compound as effect optimization after soil conditioner in addition, the acid-base value of acid stronger tea garden soil can be significantly improved, and then Se from Soil is activated, substantially increase the content of soil chemistry validity selenium, for tea tree provides effective selenium that can be absorbed and used in a large number, demonstrate the huge prospect of production development selenium-enriched tea leaf.Biological organic fertilizer contains a large amount of features microorganism fungus kind, play the effect of conditioning soil microbial community, can greatly promote that tea root grows, white capillary root is stimulated to produce, improve Root Absorption ability, by chemistry in soil effectively selenium sorption enhanced be biologically effective selenium in tea tree body, reach the object of producing selenium-enriched tea leaf.
Acid stronger Se rich tea Orchard Soil has a high potential for selenium, but to make full use of selenium-rich soil Development and Production selenium-enriched tea leaf must improve Selenium in Soils activation rate and can availability.Therefore, utilize soil conditioner to improve acid tea garden soil physicochemical property utilizes biological organic fertilizer raising tea root absorbing capacity separately to ward off path to regulate and control tealeaves selenium for producing selenium-enriched tea leaf with the validity improving Selenium in Soil simultaneously.
Three, summary of the invention
Technical problem
The object of this invention is to provide the method that selenium-enriched tea leaf is produced in the regulation and control of a kind of soil inside source, improve acid stronger tea garden soil physicochemical property, tea garden soil acid-base value can be improved, increase chemistry effectively Se content in soil; Improve tea root absorbing capacity, effective for soil chemistry selenium can be converted into biologically effective selenium in tea tree body, and then reach the object of producing selenium-enriched tea leaf, simple to operate, successful.
Technical scheme
1, the method for selenium-enriched tea leaf is produced in soil inside source regulation and control provided by the present invention:
(1) fertilizer is selected: use straw charcoal, quicklime powder and fused calcium magnesium phosphate as the modifying agent improving soil physico-chemical property; Use every gram of biological organic fertilizer at least containing 0.5 hundred million effective viable bacterias as the promoter of improving tea root absorbing capacity.
(2) soil conditioner base is executed: during the fertilizing in autumn of tea place, the ditch of about 20cm has been ploughed inside the drip of tea ridge in the ranks, every mu uses straw charcoal 250-300kg, quicklime powder 50-60kg and fused calcium magnesium phosphate 50-60kg, three kinds of materials in mass ratio 5: 1: 1 apply in ditch, then with soil, ditch is covered.
(3) biological organic fertilizer base is executed: be manured into soil modifying agent after 1 month, inside the drip of in the ranks other side, tea ridge, tea place, plough the ditch of about 20cm more equally, according to the amount of every mu of 50-60kg biological organic fertilizer mixed with soil 1: 1 and mix even bar and apply in ditch.
Invention effect
The inventive method significantly can improve acid tea garden soil physicochemical property, improves tea garden soil acid-base value, increases soil available Se content, regulation and control Selenium Content in tea.After using the method, Selenium Content in tea reaches 0.97 ± 0.02mg/kg, and in the ordinary tea leaves of non-Spraying Se-fertilizer, Se content is 0.28 ± 0.01mg/kg, and tealeaves Se content improves nearly 3 times.According to NY/T 600-2002 Se rich tea standard (Se rich tea 0.25-4.0mg/kg), the tealeaves that the method is produced fullys meet Se rich tea standard, has the quality effect same with artificially mending selenium method, and without external source selenium security risk.
