中草药肥在洋葱上的应用效果研究

Application Effect of Chinese Herbal Medicine Fertilizer on Onion

为提高洋葱的品质以及在洋葱生产中大面积应用中草药肥,以从陕西中德禾正生物科技有限公司引进的中草药肥为研究对象,以洋葱为试验作物,开展了中草药肥在洋葱上的应用效果研究。结果表明:施用磷酸二铵300 kg/hm^(2)(常规施肥基础上减施40%)+中草药肥3600 kg/hm^(2),洋葱单球纵径、横径平均分别为10.79、8.87 cm,单球重436.75 g,株高88.56 cm,假茎粗1.49 cm,鳞茎可溶性糖含量为5.45%,维生素C含量为6.28 mg/100 g,可滴定酸含量0.21 mmol/100 g;鳞茎平均产量为104.7 t/hm^(2),较施用磷酸二铵495 kg/hm^(2)处理增产3.2 t/hm^(2),增产幅度为3.15%。

In order to improve the quality of onions and apply Chinese herbal medicine fertilizer on a large scale in onion production,a study was conducted on the application effect of Chinese herbal medicine fertilizer on onions by taking Chinese herbal medicine fertilizer imported from Shaanxi Zhongde Hezheng Biotechnology Co.,Ltd.as research object and using onions as experimental crops.The results showed that applying 300 kg/hm^(2) of diammonium phosphate(reduced by 40%on the basis of conventional fertilization)+3600 kg/hm^(2) of Chinese herbal medicine fertilizer,the vertical diameter and horizontal diameter of onion bulbs were 10.79,8.87 cm,respectively,a single bulb weight was 436.75 g,plant height was 88.56 cm,false stem diameter was 1.49 cm;the soluble sugar content of bulb was 5.45%,vitamin C content was 6.28 mg/100 g,and titratable acid content was 0.21 mmol/100 g;the average yield of bulbs was 104.7 t/hm^(2),the average yield of bulbs applying above treatment was 3.2 t/hm^(2) higher than that of applying of 495 kg/hm^(2) of diammoniumphosphate treatment,with a increase of 3.15%.
