The effects of four different fertilization patterns, no application of P, single application of chemical P fertilizer, cycling reuse of organic residues (rice straw, pig feces and green manure) and cycling reused of organic residues incorporated with chemical P, on Olsen-P in paddy soil, P content in grain and haulm of rice as well as the P uptake and accumulation at different growth durations of rice were studied using the samples taken from a long-term experiment field of the Taoyuan Station of Agro-ecosystem Observation, Chinese Academy of Sciences.

采用动态采样结合室内分析方法，比较研究了中国科学院桃源农业生态实验站的长期田间定位试验中长期施与不施磷肥、有机物料循环再利用和在有机物料循环再利用的基础上配施磷肥等几种施肥模式对土壤Olsen-P含量、水稻不同生育期茎叶和子实磷含量、以及各生育期累积吸收和利用磷的影响。

Filled with relatively good soils, these lowlands have supported much of the Pacific Coast's agriculture.

充满相对良好的土壤，这些低洼支持远的太平洋沿岸的农业。

Soil phosphorus as agricultural non-point source pollution is one of the main factors which lead to water pollution.

土壤磷素的农业非点源污染是导致水体污染的最主要的原因之一。

Rational fruit variety distribution and scientific management based on soil fertility is an important prerequisite for high yield, fine quality, high efficiency, low consuming, sustainable agriculture.

根据土壤肥力进行合理的品种布局和科学的田间管理是发展高产、优质、高效、低耗、可持续农业的一个必要前提。

Subsistence agriculture and livestock rearing occupy most of the working population, although development is hampered by primitive techniques, poor soil and climatic conditions, and a chronic labour shortage.

自给自足的农业和牲畜饲养占大多数的工作人口，但发展也受到原始的技术，在贫瘠土壤和气候条件，和慢性劳工短缺。

The soil salination is a significant abiotic stress for agricultural production and ecological environment.

土壤盐渍化是影响农业生产和生态环境的一个非常重要的非生物胁迫因素，也是现代生物科学迫切需要解决的问题。

The leaching and transferring of 95Zr in different soils and its actions in several aquatic and terraneous ecosystems were studied by using the isotope tracer techniques.

本文采用同位素示踪技术研究了~(95)Zr在不同土壤中的淋溶、迁移和在几种水生及陆生生态系统中的行为，为探明~(95)Zr在不同农业生态环境中的行为规律提供基础资料，对制定有关安全标准和污染治理提供了科学依据。

Tests show that the clustering algorithm's accurate rate is higher than the unweighted fuzzy clustering algorithm.

将其改进的算法运用到精准农业的土壤肥力评价中，试验结果与实际情况相符，证明了该算法的有效性。

The results indicated that the transfer and loss of N and P vary with means of rotation, types of crops and the amount of fertilizer application. Buffering forest belts betweens farmlands and ditches can effectively stop and purify such elements as N and P in soil runoffs, thus controlling non-point source pollution of agricultural lands.

结果表明：农田生态系统中 N、P等迁移、淋失状况随轮作方式、作物种类及施肥状况而变化；农田与沟渠间的缓冲林带具有截留和净化土壤径流中的N、P等物质的作用，从而在一定程度上控制农业非点源污染。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
