The coherency test also results that the coherency between soil enzymes and available nutrient in the film-covered film is higher than that in the no-film-covered field.
从相关性测定亦表明：覆膜处理耕层主要土壤酶与有效养分之间相关性高于未覆膜处理。
The results indicated that the soil organic matter and total N of 26-year-old PBCA stand increased. the activities of soil biochemistry strengthened. the amount of available nutrient supply enhanced.
得出结果：26年生杉阔轮栽模式土壤有机质和全N含量增加．土壤生化活性加强．土壤速效养分供应量增强；
SC27 could improve available nutrient contents in soil and increase the contents of nitrogen, protein, sugar and starch in leaves of watermelon and balsam pear plants.
这与SC27促进土壤养分有效化，提高植株叶片中氮、蛋白质、糖和淀粉含量有关。
K fertilizer efficicency on various crops seemed to de relevant to N/K ratio in the available nutrient of soil.
