大豆“高肥加化控”与普通栽培措施的比较试验

Comparative Experiment of Concentrated Fertilizer-Chemical Control and Common Cultivation Measures of Soybean

试验分两个处理:①只施种肥和追肥,②在此基础上增施羊粪、硫酸钾、尿素和硫酸锌作基肥。结果表明和处理1相比处理2可以使株高降低9.0%,节数增加3.8%,最大叶面积指数减少19%,单株荚数增加8.7%,产量达到5 880 kg/hm2;而处理1,即在一般的施肥水平条件下,产量也达到了5 410 kg/hm2。试验表明:在实际的大豆生产中,通过简化栽培措施,少的肥料的投入和通过水、肥的调节来控制大豆群体的生产,也可以实现高产。这个结果在实际的大豆生产中有着重要的意义。

The results of soybean production in two different planting and management systems showed that the plant height was reduced by 9.0%, the pods number per plant were increased by 8.7% by using more fertilizer and the yield reached 5 880 kg/hm^2 ; Meanwhile, under the conditions of normal fertilizer application, the relatively high yield was 5 410 kg/hm^2, which was gained when the soybean production was controlled and adjusted by irrigation and fertilization. The experiment indicated that the high yield can be achieved in the practical soybean production because the crop growth can be control and adjusted by irrigation and fertilization. The result was significant to the soybean production.
