我省在五十年代末和六十年代初小粒种咖啡生产中普遍采用每亩种植222株以下的密度,单位面积干豆产量较低。八十年代初,潞江农场在1958年建立的2.4亩适当密植试验的基础上,采用亩植400株左右的密度,获得了高产。近年来,国外一些咖啡植区进行小面积高密度栽培试验结果亦获得了高产。在云南低海拔咖啡植区环境条件下,小粒种咖啡究竟以何种种植密度为宜?我们于1981—1985年布置了小粒种咖啡不同种植密度试验,试验结果如下: The province in the late fifties and early sixties small grain coffee production is commonly used per acre planting 222 below density, dry yield per unit area is low. In the early 1980s, based on the 2.4-mu suitable density planting test established in 1958, Lujiang Farm achieved high yield with about 400 plants per mu. In recent years, some foreign coffee plantations for high-density cultivation of small area results also obtained high yield. In Yunnan low-altitude coffee plantations under the environmental conditions, what kind of planting density of small grains of coffee is appropriate? We arranged in 1981-1985 different seed density coffee seed cultivation test, the test results are as follows:
