NOVELTY - Selenium-enriched tea planting comprises tea tree seedling and planting: selecting acid brick red soil (latosol) of mountain slope, tea tree seedling according line interval is 75x 100-110 cm plant, the tea tree seedling and planting depth is 35 cm, seedling in slope where each separate region is 2-3 column and each separate digging 2-3 row, using the pit depth reach to 40 cm, slow release device in set in the pit, two per week to selenium-enriched nutrient liquid and pouring in slow release device of 400-450 ml, after using the slow release device end sealing in tea tree.    USE - The method is useful for selenium-enriched tea planting (claimed).    ADVANTAGE - The tea has high content of selenium, can satisfy people for selenium requirement. The method achieves high selenium absorption rate.    DETAILED DESCRIPTION - Selenium-enriched tea planting comprises tea tree seedling and planting: selecting acid brick red soil (latosol) of mountain slope, tea tree seedling according line interval is 75x 100-110 cm plant, the tea tree seedling and planting depth is 35 cm, seedling in slope where each separate region is 2-3 column and each separate digging 2-3 row, using the pit depth reach to 40 cm, slow release device in set in the pit, two per week to selenium-enriched nutrient liquid and pouring in slow release device of 400-450 ml, after using the slow release device end sealing in tea tree, where the selenium-enriched nutrient liquid is obtained by using 50 pts. wt. water, 8-10 pts. wt. selenium potassium, 2-5 pts. wt. potassium fulvic acid and 15-20 pts. wt. biogas slurry, mixing uniformly, adding excrement and 1-3 pts. wt. leavening agent, fermenting at 35 degrees C for 2-3 days to obtain selenium-enriched nutrient liquid, where the slow release device is lengthways section, the upper part is open, and the slow release device height is 50 cm, applied to the organic selenium fertile and tea tree fertilizer is applied to the release device from inside to outside in turn comprises: thickness is 3-5 cm of polyethylene alcohol layer, thickness is foreign layer is 5-6 cm and thickness is 2-3 cm and sparkle stone layer, before two of picking tea tree in month, separate every half of month is the tea tree applied to organic selenium fertilizer, per acre of tea tree applying 100 kg of organic selenium fertilizer, where the organic selenium fertilizer is prepared by taking 100 pts. wt. dregs, 20-25 pts. wt. feces, 6-8 pts. wt. selenium, 5-8 pts. wt. biological protein and 0.1 pts. wt. cellulose degrading fungus, mixing uniformly, adding water for wetting, fermenting for 18 days at 35-45 degrees C, obtaining the first fermented product, using the first fermentation product filtering, obtain the first filter and the first filter liquor, taking the first filtered liquid refrigerator, using the first filter residue crushing to particle diameter is 5-8 mm, average dividing into four parts respectively added with four of the whole fermentation device, each part of adding molasses yeast for fermentation, the whole fermentation device is four respectively controlling temperature is 25 degrees C, 38 degrees C, 45 degrees C and 50 degrees C, fermenting for 3-5 days, taking out the first filter liquor, taking the average dividing into 10 parts, at 25 degrees C of fermentation device and adding 1 parts first filter liquor, at 38 degrees C of fermentation device and adding 2 parts first filter liquor, at 45 degrees C fermentation device and adding 3 parts the first filter liquor, at 50 degrees C of fermentation device and adding 4 parts the first filter liquor, continuous ferment 20-25 days, then take out, for 25 degrees C under the fermentation product, at 38 degrees C under the fermentation product, at 45 degrees C under the fermentation product and 50 degrees C of fermented product according to the following mass ratio is 1:2:2:1 mixing, to obtain the organic selenium fertilizer, adding molasses fermentation process in yeast, every two days stirring one time, and every four days to separate each of fermentation device and added with 0.5-0.6 weight parts of yeast. An INDEPENDENT CLAIM is also included for application of fertilizer comprising preserving soil moisture, applying fertilizer during December to February period, every month, one time fertilizing soil, each acre of tea tree, applying 200 kg fertilizer soil, where the fertilizer soil raw material is straw, leaves, weed and inorganic salt sodium selenite according to mass ratio 100:80:75:1-2, and retting.
