肥料

Based on the analysis of natural and human activity factors which affected soil quality, the technical methods to sustainable utilization of cultivated land resources including district improvement, rational distribution, preventing soil erosion, rational fertility fertilization, reforming the faming systems were proposed.

在人为因素中，不合理的垦荒种植，难以改变的小型四轮拖拉机表土翻耕方式，不科学的肥料使用、管理方式，以及人口增长和经济社会发展的负面影响，都促使耕地质量在演变中逐步形成退化。

Wastewater is what fertilizes the 27 strawberry plants from last summer, too.

污水从去年夏天开始，也是27株草莓的肥料。

In traditional agricultural production , farmers always fertilizes the land at their own will , which not only increased the cost of agriculture production and worsened the soil fertility , but also caused serious environmental pollution and threaten .

传统农业生产中，由于农民盲目施肥现象严重，这样不仅造成肥料利用率下降，也增加了农业生产的成本，使得耕地地力下降，而且也带来严重的环境污染，威胁农产品质量安全。

While growing, water periodically, fertilizing with a liquid fertilizer every 4 weeks.

虽然越来越多，水，定期施肥，以液体肥料，每4周。

Domestic grain and fertilizer markets both firmed into May.

五月国内谷物和肥料市场都处于稳定状态。

In about a week we'll add fertilizer which will help your newly germinated seeds grow.

在大约一周我们将会加上肥料帮助你新发芽的种子生长。

Once again, the MPP can be graphed against the level of fertilizer usage. Diminishing marginal returns indicate that the MPP curve will be downward sloping.

再说明一下，边际产量与肥料用量水平的关系可以用图表示，边际报酬递减表明边际产量曲线应该向下倾斜。

When development agriculture irrigates, need to use many fertilizer and water.

发展农业灌溉时，需使用大量的肥料及水。

Soil nitrate leaching not only causes the loss of fertilizer, but also brings about serious environmental problems.

土壤硝态氮的淋失不但造成肥料的损失，而且产生严重的环境问题。

One reason why AIFU has the best spatial coupling effect is that it has a smaller evaporation area, thus its wate loss by this way is much smaller that traditional full irrigation; leching of fertilizer nutrients is much less than traditional irrigation because fertilizer and irrigating water exists in different furrows, the residual fertility exists in above 60 cm soil profile.

水肥异区交替灌水为一种局部灌水方式，其能够提高水分利用率的原因是可减少蒸发面积，从而减少灌溉水的蒸发损失；对养分的淋溶损失少，使肥料养分主要存在于60cm以上土层。
