查询词典 nutrient solution

According to the result of artificial rainfall, the character and factors affectedby soil, rainfall, chemicals, slope length, slope gradient and field mangment practices, for rainfall, runoff,infiltration, soil erosion and soil chemicals, such as NO_3~-, NH_4~+, PO_4~(3-), K~+ and Br~-, are investigated. Thedeterminate methods, influence factors and practical application of the mixing zone depth are also researched.The results can enrich the dynamics of soil, water and nutrient transport, evaluate the soil water and fertilizerefficiency, and theoretically benefit the research of agricultural NSP on loess hill slope. 1.

本文以黄土坡地为研究对象，通过模拟降雨试验，研究土壤因素、降雨因素、化学物质理化性质、坡长坡度因素和农田管理措施等对坡地降雨—产流—入渗—土壤侵蚀—农田NO_3~-、NH_4~+、PO_4~(3-)、K~+和Br~-地表迁移的影响，研究非饱和土壤和水蚀条件下混合层深度的确定、影响因素和模拟，探讨其在黄土坡地的实际应用，为丰富坡地水分养分迁移动力学、提高旱地土壤水分养分利用率和深化农田非点源污染研究提供理论依据。

The main results are: construction of Tarim desert highway shelter-forest promoted soil microbial development, and with increase of plantation time of the shelter-forest, the quantity, fatty acid diversity index of soil microbe and diversity index of bacterial DNA segment enhanced notably. As to soil microbial community structure, bacteria are dominant population with amounting for over 80% of total soil microbe, and fungi is not more than 1% of total soil microbe, but soil microbial community structure was different among three soil layers. The conclusions from study methods of conventional culture, biological marker and molecule biology were almost identical, which illuminates that construction of Tarim desert highway made soil microbial activity enhance and so promote nutrient cycle and utilization of Tarim desert highway shelter-forest land.

结果表明，塔里木沙漠公路防护林的建设促进了风沙土土壤微生物的发育，随着防护林定植年限的增加，土壤微生物数量、脂肪酸和细菌DNA片段的多样性指数明显增大；土壤微生物区系组成中，细菌是优势类群，占微生物总数80%以上，而真菌很少，不到微生物总数1%，但在不同土层间有所差异；传统培养法与现代生物标记和分子生物学方法对塔里木沙漠公路防护林地土壤微生物多样性的研究结果基本一致，说明塔里木沙漠公路防护林的建设使林地土壤生物活性有所增强，有利于林地土壤养分循环与利用。

The study, which aimed at 100 heads of breeding cattle marketed per annual and which object was the grazing for the flock of shorthorn beef cattle on sown pasture in the ZYCBC system, indicated that by making full use of pasture growth quantity and nutrient substance on sown pasture and supplementing mixed concentrate in late of breeding cow pregnancy, the number of beef cattle grazed in the while year had get to 375 heads, for the forage was budgeted and dynamic balance between the forage and beef cattle was gained and kept. It needed 642. 67t DM of forage annually in the system, 764t DM of which was provided by the sown pasture and 339t DM of which by forage crop land.
