高粱对氮、磷肥的需要量大而土壤往往满足不了,需依靠施肥来解决。因此,研究氮、磷肥在高梁生长发育中的作用及其施肥技术,对合理施肥和提高施肥的经济效益有着重要的意义。 关于氮、磷肥对高粱生长发育的影响,李维岳等认为以氮肥或氮、磷肥混合作高粱种肥有促进早熟、增产的作用。卢庆善认为持续低温影响的年分或常温年,磷肥有促进高粱早熟和增产的作用。
Sorghum nitrogen, phosphate fertilizer needs and soil often can not meet the need to rely on fertilization to solve. Therefore, to study the effect of nitrogen and phosphate fertilizers on the growth and development of sorghum and its fertilization technology is of great significance to the rational application of fertilizers and the economic benefits of fertilization. On the nitrogen and phosphorus on the sorghum growth and development, Li Weiyue so that nitrogen or nitrogen, phosphate fertilizer for sorghum seed fertilizer to promote early maturity and increase production. Lu Qing believes that the impact of low temperature or year of year, phosphate fertilizer to promote sorghum premature and increase production.
