Description
Technical field
The present invention relates to a kind of agriculture prodn and use fertilizer, the fertilizer special for tea trees of knob, particularly a kind of suitable middle and lower reach of Yangtze River growth of tea plant.
Background technology
Tea tree is perennial picking leaves crop, and cultivated area is distributed in southern areas such as Zhejiang, Fujian more than 98%, as long as soil is subacidity or acid-reaction, and can both normal growth.Jurong City is located in south, middle and lower reach of Yangtze River bank, is the handing-over area in Taihu Plain, Ning Zhen hills, three multi-form agriculture districts, riverine country fair district, and landform is high in the east and low in the west, is main with low mountains and hills.Domestic soil pilosity is educated the old and new's alluvial deposit and following another name for Sichuan Province loess matrix in the Changjiang river, and pH value is average 6.0, and most regional soil are slightly acidic, and the tealeaves area has nearly more than 40,000 mu at present, is that Jiangsu Province mainly produces one of tea county.Well-known brand has " the emerald green bud in Kingsoft ", " Maoshan Mountain is green for a long time ", " precious Hua Yusun " etc.; In national tealeaves comparation and assessment in recent years; Successively win special award, gold medal; 4 special awards are won in another act in 2008 in " middle teacup ", be one of county of 4 special awards of whole nation acquisition, and the comparation and assessment total points is in the whole nation first.But the whole city has 50% tea place to be dispersed in each small towns peasant's hand at present; Build that the garden standard is low, extensive management, Fertilization Level be not high, per unit area yield is low, quality product is uneven, and knob, the middle and lower reach of Yangtze River; The systematic study of tea tree fertilizer practice aspect is less; The tea grower has certain blindness in the tea tree fertilising, do not consider the four characteristics of tea tree nutrition, i.e. " happiness ammonium property ", " disliking calcium property ", " gathering aluminium property ", " low chlorine property ".General calcium, an ammonium nitrate, ammonium chloride are still used in the tea tree fertilising, have seriously run counter to the fertile characteristics of suction of tea tree, so that have influenced the yield and quality of tealeaves.
The four characteristics of tea tree nutrition is specially:
" happiness ammonium property ": the transamination enzymic activity is stronger in the tea tree body, is prone to ammonium nitrogen is converted into amino acid; And a little less than the activity of nitrate reductase, after being difficult for nitric nitrogen is converted into ammonium, resynthesis amino acid.
" dislike calcium property ": tea tree is lower more than tens times than general crop to calcium, and active calcium oxide surpasses at 0.2% o'clock in the soil, often makes the calcium oxalate crystal of blade, and growth will be undesired.
" gather aluminium property ": tea tree can strengthen the growth of photosynthesis and root system on the contrary to suitable high-load aluminium, promotes the metabolism of theanine and catechin, and to the absorption of phosphorus in the soil.
" low chlorine property ": tea tree is prone to take place the chlorine evil childhood, and the back of growing up is not too responsive to chlorine.
The source of manure should be used general calcium, an ammonium nitrate, ammonium chloride less how with phosphorus ammonium, sulphur ammonium, urea, vitriolate of tartar etc., just meets the nutritional characteristic of tea tree.
Tea tree is more to the nitrogen demand, secondly is phosphorus, potassium, roughly is close with the tealeaves assimilation ratio.Generally whenever gather 100 kilograms on bright leaf needs 1.2～1.4 kilograms of absorbed nitrogens (N), 0.20～0.28 kilogram in phosphorus (P 2O5), 0.43～0.75 kilogram in potassium (K2O), N: P2O5: K2O average out to 1: 0.18: 0.45.If 450 kilograms of per mu yield fresh teas need absorption of N-P 2O5-K2O average out to 6-1-3 kilogram.The nutrient demand kind is many, not only wants nitrogen fertilizer application, and will execute trace element fertilizer in phosphorus, potash fertilizer and magnesium, sulphur, copper, iron, the zinc etc., to satisfy the needs of tea tree to various nutrients.It is suitably many that the consumption of fertilizer is wanted, the large tea of every product 100kg, and mu is executed purity nitrogen 12～15kg, is the famous-brand and high-quality tea of raw material like tea yield in young tender shoots leaf, and then dose need improve 1～2 times.But every mu of each amount of application of chemical nitrogen fertilizer (purity nitrogen meter) does not surpass 15kg, and year the highest consumption must not surpass 60kg.
Fertilising with to process tea leaf quality influence very big, is used suitable nitrogenous fertilizer to growth of tea plant, not only can increase Yield, and promote the color and luster and the sugariness of tea making.Phosphorus potash fertilizer can make strongly fragrant, and phosphorus is the nucleus important component, and its effect is the growth of each part of promotion tea tree, and solid its limb.According to India Tea Industry association research, thinking must have phosphorus matter nutriment in a fertilizer to stimulate, so use an amount of phosphate fertilizer, the enhancement tea aroma by aromatic-oil content in the tealeaves.Potash fertilizer for the strong tissue of limb, recovers tree vigo(u)r, and the opposing disease and pest is all powerful.Inappropriate like the applying fertilizer cooperation, or do not apply fertilizer, tea growth is short and small, and matter is hard, and heart bud is easy to launch, and it is not good to process the tealeaves profile, and flavour is also owed dense Gan Run.Improve tea-making quality, must pay attention to each nutrient proportioning of fertilizer.Copper zinc closes to execute to be had than remarkable influence tea leaf quality.Amino acid in the tealeaves and caffeine content mainly receive the influence of zinc concentration; Tea-polyphenol and soluble sugar content mainly receive the influence of copper concentration.Copper can promote the content of tea-polyphenol and soluble sugar in the tealeaves, and zinc then can promote the content of amino acid and trimethyl-xanthine in the tealeaves, and the complementation of copper zinc helps the raising of tea leaf quality.
In recent years, knob, the middle and lower reach of Yangtze River is along with the increase of nitrogen fertilizer amount and improving constantly of tea yield; The input ratio average out to of nitrogen, phosphorus, potassium three elements 1: 0.33: 0.17 shows that the plain ratio of nitrogen, phosphorus is too high, and potassium is plain not enough; Simultaneously; Ignore and execute trace element, pollute because of improper fertilization has caused heavy metal accumulation, water body nitrate in the part plot, has also influenced quality of tea leaves simultaneously.Also there is not at present a kind of fertilizer special for tea trees to knob, middle and lower reach of Yangtze River growth of tea plant nutritive property.On the tea tree crop, be necessary to reduce nitrogen, phosphorus element, it is plain to improve potassium, and trace element supplement can improve tea leaf quality like this, reduces cost, and optimizes the tea place environment, promotes the Sustainable development of Tea Production.
Summary of the invention
The purpose of this invention is to provide a kind of is that carrier contains the special-purpose fertile of trace element with peat, and the fertilizer special for tea trees of knob, a kind of suitable middle and lower reach of Yangtze River growth of tea plant particularly is provided.According to vast knob, middle and lower reach of Yangtze River soil characteristic,, obtain a kind of nitrogen, phosphorus, potassium, magnesium, copper, iron, manganese, fertilizer special for tea trees that the zinc ratio is moderate through reasonable blending according to the nutrient requirement of growth of tea plant.
