以GE9316、S5309、郎瑞5号、郎瑞8号、GL4601、茁泰长粒香等6个向日葵品种作为引种对比试验材料,调查其生长发育性状和产量情况。结果表明:朗瑞5号产量最高384.6kg/666.7m~2,茁泰长粒香最低192.3/666.7m~2。生产上可选择株高、葵盘大小适中的品种种植,如选择朗瑞5号等株型高大的品种,可适当降低播种密度、实行垄做栽培,适当控制株高、防倒伏,更好地发挥品种增产增效的作用。
Six sunflower cultivars, GE9316, S5309, Langrui 5, Langrui 8, GL4601, Zhuo Tai Chang Xiang, were used as the comparative test materials to investigate their growth traits and yield. The results showed that the highest yield of Longlie 5 was 384.6kg / 666.7m ~ 2, and the lowest of Longtai Longxiang was 192.3 / 666.7m ~ 2. Production of choice of plant height, Kwai plate medium size varieties of planting, such as the selection of Long Rui 5 and other plant type tall varieties, may be appropriate to reduce planting density, the implementation of ridge cultivation, appropriate control of plant height, lodging, better Play a variety of the role of increasing efficiency.
