山地林茶综合开发的研究

STUDIES ON SYNTHETIC DEVELOPMENTS OF FOREST-TEA ON HILLY LANDS

山地林茶多经综合开发研究的目的在于：通过营造速生丰产林，改善林茶生态环境，生产林产及林副多经产品；利用林地枯枝落叶覆盖茶园；在茶园间作黄豆、玉米，实行以短养长，实现茶园持续、优质、稳产。12年的研究结果表明：7．8公顷丰产林，除改善林茶生态环境外，立木蓄积量已达1004立方米；利用林产进行林产转化种植木耳、香菇、天麻等收入91541．40元；林地每年产枯枝落叶15T覆盖茶园，保水，保温，增肥，建成每公顷产815公斤茶叶的优质、稳产茶园，已生产“白杨春萌”优质茶三年，2．2公顷茶园收入共51022．26元；茶行间作黄豆、玉米固氮遮荫，以短养长，总收粮6000公斤，折合人民币9600元。12年的林茶农总收入为142563．66元，投入产出比为1：4．89。

This program was conducted to investigate the effects of syn-thetic development of hilly land by diversified management of forestry and tea plantation on environment and that of the environment on forest products and tea out-put.Twelve years' study showed that the 8 ha of forest has brought about great returns in several ways. First, the forest itself has stored up 1004m3 of timber. secondly, a profit of 91541. 40 yuan has being made from various forest by products like muer and xianggu mushroom, two edible fungi, and tianma, the tuber of elevated gastrodia. And above all, the forest has improved the environment and thus made it better for the tea plantation nearby. Furthermore, 15t of fallen leaves and twigs from the forest were collected each year to cover soil of the tea grove, and so the soil can better conserve water, fertilizer and wormth, which, together with other factors, contributed a lot to the steady production of 'Baiyang chunmeng', a type of high quality green tea. The tea production was as high as 795kg/ha. As a result, the only 2.2 ha of tea grove has created a profit of 51022.25 yuan. In addition, when we tried to grow crops like bean and corn between rows of tea plants to help fixating nitrogen and giving shade, we havested 6000kg of corn and bean so far, which is worth 9600 yuan. So the total returns in twelve years are 142563. 66 yuan and the ratio of input to ouput is 1:4.89.
