七十年代初我省开始引进箭舌豌豆试种,到七十年代末,箭舌豌豆的利用面积累计达40万亩,在麦棉、麦苞两熟地区预留行间套,从农业内部解决有机肥源,收到了较好的经济效果。为了进一步选择适应性更广,产量更高,能与多熟制配套应用的箭舌豌豆新品种(系),我们在已往试验的基础上,通过多年多点观察比较,筛选出一批鲜草与种子产量分别比大面积推广种“66—25”增产20—25％和10—15％,生育期比“66—25”晚5—7天,但比苕子早10—15天的箭舌豌豆种(系)。1980—1985年,在省内有代表性的地区进行了区域试验,现将六年结果汇总如下。
In the early seventies, the province began to introduce the tongue-pea seed trial. By the end of the seventies, the total area for the use of the tongue-opening pea reached 400,000 mu. There was a reservation for intercropping between two areas of wheat and wheat buds, Solve the organic fertilizer source, received a better economic results. In order to further select more adaptable new varieties (lines) with higher yield and compatibility with multi-cooked products, based on the previous experiments and through many years of observation and comparison, a batch of fresh grass And the seed yield increased by 20-25% and 10-15%, respectively, than the large-scale promotion variety “66-25”, and the growth period was 5-7 days later than that of “66-25” Tongue pea species (Department). In 1980-1985, regional experiments were conducted in representative areas in the province, and the results of the six-year summaries are summarized below.
