目前,我县蚕豆播种面积5.46万亩(过去曾达八万多亩),单产326斤(过去平均亩产200斤左右),分别占小春粮豆播种面积的34％和小春粮豆产量的34.22％。本文试就尚未全面推广或推广不力的几个技术措施问题提出一些看法。一、整枝我地蚕豆品种一般有2—5个分枝。就多数地区来说,主茎在分枝增长过程中自动消亡,但在低热河谷地区和土壤瘦薄田块,分枝极少,依靠主茎结实。在大面积生产中,无效分枝是普遍存在的,并有争光、争肥、引起落花落荚的副作用,应及时彻底整除。据调查,在一般大田中,无效分枝约占15—21％。(见表一)
At present, my county broad bean sown area of 54,600 mu (in the past had reached 80,000 mu), yield 326 pounds (in the past average yield of about 200 pounds), respectively, accounted for 34% of Xiaochun grain sown area and spring bean production 34.22 %. This article tries to put forward some views on several technical measures that have not been fully promoted or under-promoted. First, pruning My fava beans generally 2-5 branches. In most areas, the main stems die off automatically during branch growth, but in the low-thermal-valley areas and thin-field soils, there are few branches and the main stems are strong. In large-scale production, ineffective branching is ubiquitous, and there is a win-win situation, fighting for fertilizer and causing side effects of falling flowers and pods. According to the survey, in the general field, invalid branches account for about 15-21%. (See Table I)
