有机茶叶的生产技术指标初探

Preliminary Approuch to the Technique Targets of Production of Organique Tea

研究了有机茶叶生产的管理技术及其量化指标。茶园每生产１０ｋｇ茶叶，必须投入纯有机Ｎ１ｋｇ以上，其中２０％沤制水肥作追肥，在采茶旺盛季节进行多次追施有机水肥，不施化肥一样可以获得高产，而且能明显提高茶叶品质，改善土壤理化性状，提高土壤肥力；在自然控制下，天敌蜘蛛与害虫小绿叶蝉比可稳定在１∶２～１∶３之间，结合及时采摘，其比值可降低到１∶２左右水平，不施农药，基本可控制小绿叶蝉的危害。

Management techniques and quantification targets of the production of organic tea were investigated to produce 10kg of tea more than 1kg of organic N fertilizer (20% of wet compost as top application) was needed to be applied annually over the tea garden,During the vigorous tea picking period,organic fertilizer was also found to be better than chemical fertilizer The tatio between.Spider (naturally enemy) & fabricius (injurous insect) was 1∶2～1∶3 under the naturally controlled condition.Combined with seasonable picking,it declined to 1∶2;without appliacation of pesticides,harms due to fabcicius can be controlled basically.
