氢氧化镁功能型中量元素肥料在晚稻上的应用
Application of functional magnesium hydroxide meso-element fertilizer in late rice
摘要
Abstract
This study investigated the effects of applying a functional magnesium hydroxide meso-element fertilizer under conventional nitrogen fertilization and 15%nitrogen reduction on yield traits,agronomic traits,nitrogen uptake,and grain quality of late rice variety Yongyou 1540.The results showed that compared with conventional nitrogen application,the addition of the magnesium hydroxide meso-element fertilizer increased rice yield by raising the number of spikelets per panicle and effective panicles,with the application rate of 10 kg per 667 m² performing better than 5.0 kg.Even under the 15%nitrogen reduction condition,a relatively high yield level was maintained.In addition,the application of this magnesium fertilizer reduced chalky grain rate and increased gel consistency,thereby improving rice processing and nutritional quality.In summary,it is recommended to apply 5.0-10.0 kg of the functional magnesium hydroxide meso-element fertilizer per 667 m² on the basis of conventional fertilization with 15%nitrogen reduction,which can both enhance rice yield and improve grain quality.The fertilizer should be applied as a basal dose as early as possible.关键词
