Studies On The Application Of EM Fertilizer

The results of contrast experiments of utilizing EM fertilizer by way of the multiple choices of different types of tea gardens, peanut gardens and cucumber gardens show that microorganism fertilizer usually came into effect around 20 days after applied to the tea. It promoted the early-onset shoots, so that the high price fresh tea could come into the market earlier; it increased tea yield by 8.99% of the fourth batch of spring tea output and 43.6%-44.9% of first and second batch of autumn tea. It could improve the tea quality by maintaining the young shoots longer and bigger, increasing the specific bulk density, improving the taste and flavor, decreasing the acerbity and bitterness et al. It improved the resistances of tea tree to water logging, cold, diseases and pests as well.When applied to peanuts, the microorganism fertilizer improved the plant growth, enlarged peanut kernels, increased the luster of seed coat and the grade of peanuts. It had a better effect on increasing the yield of seed (about 12.2% increased) than that of phosphate fertilizer applied alone. It also showed a strong effect to prevent the death of young seedlings and diseases. So, the microorganism fertilizer can be used as a special fertilizer for the production of green food, and should be used extensively in the ecological agriculture gardens as the most important fertilizer.While applied to cucumber, the microorganism fertilizer increased the livability of transplanted seedlings and promoted the plant growth. Compared with the other fertilizers, it increased the plant height of 40.8cm over the control, 3.7% and 83% increased of root number and fruit yield respectively, increased the yield of young, fresh, tender and good shape fruits. It also enhanced plant resistance to diseases and prevented the death of young seedlings.The most favorable conditions to use the microorganism fertilizer are as follows: it has a better effect under the conditions of sufficient soil water and soil organic matter, and on the soil unbalanced fertilization with too much nitrogen or the infertile soil.
