浙江省黄红麻生产自七十年代实行“南种北栽”以来,单位面积产量有了显著提高。但“南种北栽”应用的是广东等省的晚熟类型品种,在本省钱塘江两岸的主产麻区留不到成熟种子,需要年年向南方各省大量调种。这不仅浪费人力物力,而且造成品种单一,混杂严重,种性退化,有时还延误播种季节,影响种植面积。为了研究出既能保持“南种北栽”的增产优势,又能在本省留到较多种子的方法,我们于1979—1982年,在浙南平阳县进行了黄麻留种技术的研究。
Yellow kenaf production in Zhejiang Province since the 1970s the implementation of “south of the North planted” since the unit area yield has been significantly improved. However, the “southern planting in the south” is a late-maturing variety used in Guangdong and other provinces. Mature seeds are not found in the main producing areas across the Qiantang River in the province and need to be planted in large quantities in the southern provinces every year. This not only wastes manpower and material resources, but also results in a single species, a mixed species, a degenerative species, and sometimes a delay in sowing season, affecting the area planted. In order to study the method of maintaining the yield advantage of “planting south of North China” and reserving more seeds in this province, we studied the technology of jute seeding in Pingyang County of southern Zhejiang from 1979 to 1982.
