1982年以来,我县红花草播种面积一般在24～26万亩之间徘徊,去年下降到产22万亩,仅占早稻面积的66％。红花鲜草亩产也由1982年前的2000多公斤下降到目前的1000公斤左右。为了恢复和发展我县的冬季绿肥生产,特别为大面积红花草高产探索一套行之有效的高产栽培技术,198年冬种时,在省农科院的大力支持下,我们在大洋洲、力江两乡建立了两个千亩连片红花草高产示.范片。据今年4月红花翻沤前测产,示范片平均亩产鲜草3125公斤。其中20％亩产鲜草达4090公斤。总结示范片红花草丰产经验,我们主要抓了以下四项技术措施。
Since 1982, the sowing area of safflower and grass in our county has generally hovered between 24 and 26 million mu, down to 22 million mu last year, accounting for only 66% of the area of early rice. Red fresh grass per mu from 1982 before more than 2000 kilograms down to the current 1000 kg. In order to restore and develop my county’s winter green manure production, especially for a large area of high yield of cauliflower to explore a set of effective high-yielding cultivation techniques, 198 winter species, with the strong support of the Provincial Academy of Agricultural Sciences, we in Oceania, Jiang Liangxiang established two acres of coniferous red flowers high yield shows. According to this year in April before the safflower overturned test, the average yield of demonstration plots of fresh grass 3125 kilograms. 20% of which yield 4090 kg of fresh grass. To sum up the experience of high yield safflower grass, we mainly focus on the following four technical measures.
