目前,四川省茶园总面积已超过23.92万hm2,居全国第二,产值居全国第四,其中家庭型茶园达到90%以上。在茶园机械化管理方面,家庭型茶园多在修剪环节使用机械,几乎不机耕或仅有少量旋耕机作业,导致茶园土层板结严重,影响茶叶产量和品质,甚至影响到茶叶出口。究其原因主要是市场上的农田耕作机动力不足、宽度偏大和浅旋耕作,无法满足家庭型茶园的深松耕作需求。因此,课题组以四川省洪雅县、雅安名山区和峨眉山市三大产茶大县的1.52.0 m
At present, the total area of tea plantations in Sichuan Province has exceeded 239,200 hm2, ranking the second in the country with the output value ranking fourth in the country, of which the family-oriented tea plantations have reached more than 90%. In mechanized management of tea plantations, family-owned tea farms mostly used machinery in the pruning process with little or only a small amount of rotary cultivator work, resulting in serious compaction of the tea plantation and affecting the yield and quality of tea and even affecting the export of tea. The main reason for this is that the farmland tillers on the market are under-powered, with large width and shallow-tillage farming, which can not meet the needs of deep-plowing of family-owned tea farms. Therefore, the project team to Hongya County in Sichuan Province, Ya’an Mingshan and Emeishan City, the three major tea-producing counties 1.52.0 m
