富硒水溶肥对猕猴桃增硒及增产的效果

为探索硒肥对猕猴桃的增硒及增产效果,于2016年选用"康熙宝"富硒水溶肥在湘西自治州凤凰县"红心猕猴桃"品种上进行了叶面喷施试验。结果表明,喷施康熙宝富硒水溶肥(幼果期和壮果期2次喷施,每次用水溶肥100 m L对水100 kg/667m~2)的处理比对照(只喷等量清水和不喷硒肥及清水)平均增硒0.026 mg/kg,含糖量降低0.4~0.5个百分点,含酸量比对照下降0.03个百分点,糖酸比提高了0.8~1.0,可溶性固形物提高0.9%;平均增产6.8%~8.6%,增产效果达到极显著水平。经农业部检测,猕猴桃含硒量达到湖南省地方标准《富硒产品硒含量标准》。说明施用康熙宝富硒水溶肥对红心猕猴桃的增硒和增产效果显著,可大面积推广应用。

Effects of Selenium Enriched Water Soluble Fertilizer on Selenium and Yield Increase to Kiwifruit

In order to explore the effect of selenium fertilizer on selenium and yield increase to kiwifruit, a foliage-spraying was conducted by using "Kangxi Bao" selenium enriched water soluble fertilizer on "red-fleshed kiwifruit" in Fenghuang county, Xiangxi Autonomous Prefecture in 2016. The results showed that the results of the controlled trial which contained the experimental group, spraying Kangxi Bao selenium enriched water soluble (spraying two times in young fruit period and growth period, 100 mL of water soluble fertilizer to 100 kg/hm2 of water each time) and the control group (only equivalent water to no selenium fertilizer and water) showed that the selenium average increased 0.026 mg/kg, the sugar content decreased 0.4-0.5 percentage points, the acid content was 0.03 percentage points lower than the controlled, the sugar acid ratio increased 0.8-1.0, soluble solids increased by 0.9-1.1 percentage points, the average yield was 6.8%-8.6%higher, and the yield increased significantly. Detected by the Ministry of Agriculture, the selenium content in kiwifruit required standards of Hunan Provincial standard (Selenium content of selenium enriched products). It was concluded that the application of "Kangxi Bao" on red-fleshed kiwifruit can largely increase the content of selenium and yield, which can be widely applied.
