一、试验目的: 每年秋冬季节进行一次茶园土壤浅耕是我场的一项管理常规。近年来,学术界对于茶园耕翻的深浅程度及是否有必要进行耕翻之类问题有所争论。本试验是根据我场的具体情况,探讨一下茶园在进行免耕、浅耕和深耕处理时,其经济效益的优劣。二、基本情况: 供试茶园是我站197G年春播种的试验茶园。地面坡度均为15℃左右。播前的土壤耕作和种后的肥培管理水平基本一致。1980、1981两年试采,1983年正式投产。
First, the purpose of the trial: every autumn and winter seasons to do a shallow tillage of tea garden is a field of management practices. In recent years, academics have argued about the extent of plowing in tea gardens and whether it is necessary to plow them down. This experiment is based on the specific circumstances of my field to explore tea plantation in the no-till, shallow tillage and deep plowing treatment, the pros and cons of its economic benefits. Second, the basic situation: The test tea plantation is my station 197G spring sown trial tea plantation. Ground slope are about 15 ℃. Pre-sowing of soil cultivation and seed management training is basically the same level. Trial mining 1980,1981 two years, formally put into operation in 1983.
