自1987年以来,我们就开始茶叶施用稀土的试验示范,几年来累计施用面积2300多公顷,每667平方米增产茶叶23.4公斤,产值增加136.50元。现将其效果和施用技术简介如下: 1、喷施稀土能增加茶树的芽头数和百芽重,而且叶色嫩绿.叶肉增厚。据春茶期试验,喷稀土后20天调查,平均每平方米总芽头数比对照多102个,增加22.67％,百芽鲜重增加1.1克,比对照提高16.2％。 2、喷施稀土能提高茶叶品质。据测定,喷稀土的茶叶儿茶素、咖啡碱、水浸物、茶多酚的禽量分别提高19.66％、
Since 1987, we have experimented on the application of rare earth in tea. Over the past few years, we have accumulated an area of more than 2,300 hectares and increased yield of tea by 23.4 kilograms per 667 square meters. The output value has increased by 136.50 yuan. Now the effect and application of technology are as follows: 1, spraying rare earth can increase the number of buds and 100 buds tea weight, and leaf color green. According to the spring tea period test, 20 days after spraying rare earth, the average number of sprouts per square meter was 102 more than the control, an increase of 22.67%. The fresh weight of sprouts increased 1.1 grams, which was 16.2% higher than that of the control. 2, spraying rare earth can improve the quality of tea. According to the determination, spraying rare earth tea catechins, caffeine, flooding, tea polyphenols poultry volume increased by 19.66%, respectively,
