滨海盐碱地控释掺混肥配施调理剂对玉米生长的影响
Effects of Controlled-release Blended Fertilizer with Conditioner on Maize in Coastal Saline Area
摘要
Abstract
In order to research the effect of controlled release blended fertilizer with soil conditioner on the growth of crops in coastal saline area, the experiment was conducted in the field experiment of saline land in Bohai Sea was compared with farmer conventional fertilization, according to the local soil nutrient content, to research the effects of controlled-release blended fertilizer, humic acid conditioner and bioorganic fertilizer on the soil pH, soil properties, crop yield and economic benefit. The results showed that controlled-release blended fertilizer, humic acid slow-release fertilizer, controlled-release blended fertilizer with humic acid conditioner, and controlled-release blended fertilizer with microbial organic fertilizer compared with conventional fertilization reduce the soil pH of saline soil in coastal area;other four treatments compared with the farmer conventional fertilization, the soil salinity was increased, but most of the differences were insignificant;compared with the conventional fertilization treatment, controlled release blended fertilizer increased the content of soil nitrate nitrogen and ammonium nitrogen, the highest increase was 14.5% and 16.1%; the highest 1000-grain weight value among the treatments was controlled-release blended fertilizer with humic acid conditioner, which was 353.2g, which was significantly different from the conventional fertilization treatment;among all of the treatments, the highest yield of maize and net income were the controlled release blended fertilizer treatment, which were 8832 kg?hm-2 and 2578 yuan per hectare, all reached the significant lecel;compared with the farmer conventional fertilization, the yield increased 15.32%. Taking into account, in the low salinity coastal saline soil planting corn, it is recommended to use controlled-release blended fertilizer.关键词
