黄州萝卜优化施肥及保鲜技术研究

Study on Optimized Fertilization and Preservation Technology of Huangzhou Radish

为通过优化施肥进一步提高黄州萝卜产量,增加种植效益,设置不施肥处理、优化施肥(每667m^(2)施150 kg有机肥+20 kg三元复合肥)处理和常规施肥(每667 m^(2)施40 kg三元复合肥)3个处理,探究不同施肥处理对黄州萝卜植株性状、产量和效益等方面的影响。同时,为了延长黄州萝卜保鲜期,开展了采后保鲜试验,设计2个处理,分别为3℃低温贮藏保鲜和常规贮藏对照,比较分析贮藏萝卜的品质指标。结果表明:优化施肥处理的黄州萝卜长势好,667 m^(2)产量最高,达到2909.8 kg,667 m^(2)综合效益最优,达到4941.6元,较常规施肥每667 m^(2)增产10.1%,增收457.2元。3℃低温贮藏条件下黄州萝卜品质较好,粗纤维含量、可溶性糖含量、水分含量分别为0.9%、2.9%、91.0%,贮藏效果较好。

In order to further improve the yield and increase planting benefits of Huangzhou radish by optimizing fertilization,three treatments including no fertilization treatment,optimal fertilization treatment(organic fertilizer of 150 kg per 667 m^(2)+ternary compound fertilizer of 20 kg per 667 m^(2))and conventional fertilization(ternary compound fertilizer of 40 kg per 667 m^(2))were set.The effects of different fertilization treatments on the plant traits,yield and benefits of Huangzhou radish were investigated.At the same time,in order to prolong the preservation period of Huangzhou radish,a postharvest fresh-keeping experiment was carried out,and two treatments were designed,which were of 3℃low-temperature fresh-keeping and the control conventional storage,and the quality indexes of stored radish were compared and analyzed.The results showed that the optimal fertilization treatment of Huangzhou radish grew well with highest yield of 2909.8 kg per 667 m^(2),and the comprehensive benefit was the best,reached 4941.6 yuan per 667 m^(2),which increased 10.1%and 457.2 yuan per 667 m^(2)compared with the conventional fertilization.The quality of Huangzhou radish stored at 3℃was better,the content of crude fiber,soluble sugar and water were 0.9%,2.9%and 91.0%,respectively,and the storage effect was better.
