春大豆高产栽培技术研究

Study of High-yield Cultural Technique on Spring-soybean

1988-1990年采用单项研究和综合技术研究与示范推广相结合的方法,在福建省7个春大豆主产县累计推广16万亩,平均亩产167kg,增产幅度20％以上。试验与示范结果表明,要提高春大豆产量,必须紧紧抓住提高单株饱满粒数这个中心环节,采取早播、早施苗期“启动”肥和群体合理配置等综合配套技术措施。

By the way of combining the single-item study with comprehensive techniques, and combining with the commercial planting, about 160×10~3 mu of spring—soybean had been grown at 7 main-production counties in Fujian Province from 1988 to 1990. The average yield was about 167 kg per mu, a 20% yield-increasing over common cultivation method. It demonstrated that the yield of spring-soybean in Fujian is still great potential, and limited factor is cultivation technique. The improved approach to get higher yield was as follows: earlier sowing, increasing N application in total and practising with the principals as called early-heavy, middle-limited, and late-light, and establishing a ideal population.
