有机无机复混肥在白菜上应用效果试验

Effect of Organic and Inorganic Complex Fertilizers Application on Cabbages

进行节本牌有机无机复混肥在保护地和露地种植白菜上的应用效果试验。结果表明:有机无机复混肥能给白菜提供合理养分,促进白菜良好的生长发育,莲座期比常规施肥平均提早2～3 d。经济效益分析,春季有机无机肥比常规施肥平均增产6 330 kg/hm2,投入产出比1∶7.6;秋季比常规平均增产7 665 kg/hm2,投入产出比1∶5.95,说明有机无机复混肥可以活化土壤,提高白菜的产量和品质,实现增产和增收,在今后发展无公害、绿色蔬菜生产中可以推广应用。

We had an experiment on the application of the organic and inorganic complex fertilizer Jieben to the cabbages in the protected and open fields.The results showed that organic and inorganic complex fertilizer could provide cabbages proper nutrients,making the cabbages grow better.Its rosette stage was 2 or 3days ahead of conventional fertilization on average.The analysis of economic benefits showed that application in spring increased the average yield for 6330 kg/hectare and the input-output ratio is 1：7.6.In autumn,the average yield increased 7665 kg/hectare and the input-output ratio is 1：5.95.This indicated that the organic and inorganic complex fertilizer can activate soil,increase the yield of cabbages and improve its quality,thus yield and income increase realized.In the future,it can be widely used in production of pollution-free and green vegetables.
