咩叫精耕?

精耕 = Intensive farming
Intensive agriculture is an agricultural production system characterized by the high inputs as relative to land area (as opposed to extensive farming). It usually relies heavily on the use of chemical fertilizers, herbicides, fungicides, insecticides, plant growth regulators and pesticides. It is associated with the increasing use of agricultural mechanization, which has enabled a substantial increase in production. Mechanized agriculture has become the key to the success of contemporary farming.
