求翻译：应注意的是，EM技术的土壤改良效果短期内并不明显，持续2年后，才会逐渐增加。除土壤改良作用外，EM稀释液还能增强植物的新陈代谢，在光合作用与强化叶片保护膜的促进下，可使脐橙根系更发达、枝条节间变短，成熟期提前7～10天，产量提高20%，脐橙保果率可上浮35%～50%。是什么意思？

It should be noted that the soil improvement EM technology results in the short term, it is not visible after 2 years, and then gradually increased. In addition, soil improvement, EM diluted solution can also increase the metabolism and plant photosynthesis in leaves and enhanced protection for the

Should pay attention, in the EM technology soil amelioration effect short-term is not obvious, after continues for 2 years, only then can increase gradually.Besides the soil amelioration function, the EM diluent also can strengthen the plant metabolism, and strengthens the leaf blade protective film

Should be aware of is that soil improvement effect of EM technology is not apparent in the short term, after 2 years, will gradually increase. In addition to soil improvement role, EM dilution liquid will increase the plant's metabolism, photosynthesis and strengthen the blade under the protective f
