1987年初,四川省农科院组织了资中、资阳、乐至、三台、金堂等盆中5个丘陵县红苕高产配套技术示范,虽然遭到严重干旱影响,仍然获得了红苕较大幅度增产。参加示范片的111.35万亩红苕,平均亩产达到245.2公斤(折原粮,下同),比1986年平均亩产201.63公斤净增43.57公斤,增产21.6％,总产净增4851.52万公斤,取得了较大社会经济效益。这是在继续推广一条龙经验基础上,总结生产经验,发挥红苕适用增产技术作用的结果。进一步扩大应用这套技术,将对提高我省红苕单位面积产量有着重要的现实意义。 1,加速良种推广,扩大良种面积。各地经验证明,大面积更换对路品种,
In early 1987, Sichuan Academy of Agricultural Sciences organized five high-yielding supporting technology demonstration projects for hilly redgrass in Zixin, Ziyang, Lezhi, Santai, Jintang and other basins. Despite the severe drought, they still enjoyed a substantial increase in output. The 111.35 hectares of red ginseng that participated in the demonstration film had an average yield of 245.2 kilograms (equivalent to original grain), an increase of 21.56 kilograms over 201.63 kilograms in 1986, an increase of 21.6% over the previous year, with a net increase of 48.5152 million kilograms in total output. Greater social and economic benefits. This is the result of continuing to promote one-stop experience, summarize the production experience, to play the role of red yeast rice production technology. To further expand the application of this technology will have an important practical significance for improving the yield per unit area of red crab in our province. 1, speed up the promotion of varieties, expand the area of fine varieties. Experience has proven around the replacement of a large area on the road varieties,
