黑穗醋栗是我省目前发展快、种植面积较大、经济效益较高的小浆果之一。我省具有发展黑穗醋栗的地理优势,至1987年末种植面积已达22.7万亩。自1986年以来,我们推广大面积丰产技术,使亩产由100～150公斤上升到1988年的250～400公斤,並出现了千亩超过500公斤的高产典型。现介绍大面积丰产经验如下: 一、品种的选择目前,生产栽培品种大都是从国外引进栽培七十余年的老品种,退化严重。此外,由于近几年用实生苗繁殖.后代变异较大,导致品种混杂退化。为了保持优良品种特性,生产上应采用无性繁殖育苗,如用压条、分株、扦插和茎尖培养育苗。我省主要推广亮叶厚皮和丰产薄皮两个主栽品种。
Black currant is the current development of our province, planting larger, one of the more profitable small berries. The province has the geographical advantage of the development of black currant. By the end of 1987, the acreage had reached 227,000 mu. Since 1986, we have promoted large-scale and high-yielding technologies, which have resulted in the increase of mu production from 100 to 150 kilograms to 250 to 400 kilograms in 1988 and the emergence of more than 500 kilograms of high-yielding typical models. Now introduce the experience of large-scale high yield as follows: First, the choice of varieties At present, most of the cultivated varieties are introduced from abroad cultivation of more than 70 years of old varieties, serious degradation. In addition, due to the propagation of seedlings in recent years, there is a great variation in the offspring, resulting in the degenerated varieties. In order to maintain the characteristics of fine varieties, the production should adopt asexual breeding seedlings, such as the use of pressured, ramets, cuttings and shoot tips culture nursery. The main promotion of our province Liangye thick skin and thin-skinned two main cultivars.
