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.
