有效肥力

内蒙古中、东部旱作区试验研究表明，地膜覆盖增产增效机理在于：提高土壤有效肥力；

According to the field experiments carried out on dry land in the middle and eastern region of Inner Mongolia , the increasing yield and raising efficiency principle of film covered was made clear .

施用有机肥是我国农业生产中的重要传统施肥方式，有机肥可以有效提高土壤肥力。

The application of organic manure is the traditional fertilization methods of agricultural production , and the organic manure can enhance fertility of soils .

草原土壤磷、钾肥较为缺乏，而且单纯的施用化肥效果并不好，需要配合有机肥的施用才能有效提高土壤肥力。

The grassland soil is short of phosphorus and potassium , applying organic fertilizer accompany with chemical fertilizer is more effective than applying chemical fertilizer .

大田试验表明，旱地麦田增施有机肥料，能有效提高土壤肥力，增加土壤贮水能力；

Dry field trials demonstrated that increasing the application amount of organic manure to the wheat field could enhance the soil fertility and moisture persistency ability .

有机肥能有效地提高土壤肥力，并可以有效地促进土壤有机质的增加和更新。

The organic fertilizer can raise soil fertility significantly , and increase the content of organic matter .

互作可以有效地提高土壤肥力，改善土壤的养分状况和根际养分吸收环境，维持植物生产力；

The interaction could enhance soil fertility effectively , improve nutrient status in soil and nutrient absorption in the rhizosphere , and also maintain plant productivity .

建议通过增施有机肥、种植绿肥增加土壤有机质含量，以及采取适宜的农业措施可有效促进土壤各肥力要素的形成，提升土壤肥力水平、恢复土壤生产力。

It is suggested that using organic fertilizer , planting green manure could increase content of soil organic matter , and that taking suitable agricultural measure could promote the formation of soil fertility together , generally upgrading the level of soil fertility and renew soil production .
