美国阿肯色大学大豆育种家Caviness最近的研究表明,大豆种植行距从96.5厘米减少到48.3厘米后,产量提高了17％。 Caviness指出,要夺取窄行种植的大豆高产,必须采取高大的,丛生型品种,因这些品种的生长能荫蔽杂草,使其不受杂草的影响。 1982年,Caviness用Forrest,Narrow Row,A—5474,Centenial,Davis和Braxton等品种进行了试验,发现这些品种具有较高的产量潜力和
Recent research by Caviness, a soybean-breeder at the University of Arkansas at the University of Arkansas, shows a 17 percent increase in soybean planting distance from 96.5 to 48.3 centimeters. Caviness said high-yielding sowing of narrow-row soybean must take tall, tufted varieties because the growth of these varieties can shade weeds away from weeds. In 1982, Caviness experimented with varieties such as Forrest, Narrow Row, A-5474, Centenial, Davis and Braxton and found that these varieties had higher yield potential and
