石灰氮对连作花生生理特性及产量的影响
Effects of Applying Lime Nitrogen on Physiological Characteristics and Yield of Continuous Cropping Peanut
摘要
Abstract
Pool experiment was carried out to study the effects of applying lime nitrogen on physi-ological characteristics and yield of continuous cropping peanut.The results showed that rational ap-plication of fertilizer can relieve the harmful effects of continuous cropping on peanut growth and yield, and the mitigation effects of lime nitrogen were superior to conventional quick-acting chemical fertilizer.Applying lime nitrogen facilitated the growth of main stem and lateral branch of continuous cropping peanut, improved the chlorophyll content and net photosynthetic rate, and increased NR ac-tivities and root vigor in different growth stages.In addition, lime nitrogen improved emergence rate, pods per plant, weight per pod and shelling rate of continuous cropping peanut, and consequently in-creased the pods yield.Under the condition of this test, the best treatment was 225 kg /hm2 lime ni-trogen application.关键词
