菌肥A1在结球甘蓝上的使用效果试验

本试验对从日本引进的微生物有机肥料Ａ１在结球甘蓝生产上的使用效果进行验证。结果表明：菌肥Ａ１在结球甘蓝生产上使用有明显肥效和经济效益，较无肥对照增产５７２６．７ｋｇ／ｈｍ２（７．５％），增加收入６８７２．１元／ｈｍ２，产投比为４．７７；与常规施肥相比，使用菌肥Ａ１后由于甘蓝增产５２９９．２ｋｇ／ｈｍ２（６．９％），增加收入６３５９．１元／ｈｍ２，同时减少肥料支出４０５．００元／ｈｍ２，因此增加净收入６７６４．１元／ｈｍ２。菌肥Ａ１对结球甘蓝的外叶数、开展度、株高等植株性状无显著影响。菌肥Ａ１对结球甘蓝的食用品质无明显影响；在室温条件下（２５℃）贮藏能明显延长贮藏时间，１０天后的失水率和腐烂率显著低于对照。菌肥Ａ１的肥效除了本身提供的养分而外，还促进了土壤养分的释放，增加速效Ｎ含量。菌肥Ａ１与常规肥料配合使用虽然有增产效果，但肥料支出增加，其投入产出比小于１。

AN APPLICATION EXPERIMENT OF MICROORGANIUM FERTILIZER Al IN CABBAGE PRODUCTION

The application effects of microorganium fertilizer Al imported from Japen had been tested in cabbage production. The result showed that cabbage production yield treated with Al increased 5726. 7kg/hm2 compared with CK (non of fertilizers used ),and the income increased 6872. 1 yuan/hm2. The ratio of output and cost was 4. 77 compared with chemical fertilizer 5299. 2 kg/hm2 and the cost of the fertilizer decreased 405. 0 yuan/hm2. All of above,6764. 1 yuan/hm2 profited from using Al. There were no difference on numbers of leaves,height and diameter of the plant, and the edible quantities of cabbages among thetreatments. The ratio of water evaporation decomposition of the cabbage treated with Al after 10 days preservation under 25 C were lower than that of the control. It could be found that the effective nitrogen contents in soils treated with Al was increased accompanied by high yield. Fertilizing Al mixed with otherchemical fertilizers had also got the high yield but accompanied by the cost increasing and the ratio of output and cost was less than 1.
