施肥

If it is all sorbed by the soil and not available to the plant then responses will not be seen. Again, a wrong conclusion might be made, or the trial would have to be repeated in the field.

所施养分若全被土壤吸附，难于被植物吸收，则施肥将不显效，这样可能得出施肥无效的错误结论，否则应重做田间试验。

Nutrient investigation and diagnosis of rubber plantation is the basis and core content of leading to scientific fertilization, it had played an important role on realizing the sustainable development of natural rubber planting industry.

In this paper,soil pH,the content of organic matter,total nitrogen,potassium and phosphorus,available nitrogen,potassium and phosphorus,water-soluble chlorine of the main soil types was studied in the Yunnan Tobacco-growing areas.

中文摘要：本文系统地研究了云南省植烟区的主要土壤类型的pH值和有机质、全氮、速效氮、全钾、速效钾、全磷、速效磷、水溶性氯含量等理化指标，明确了不同土壤的养分丰缺状况，依据测土配方施肥的要求，制定了合理的施肥对策。

In the tobacco production, the measure of only using fertilizers in soil can notimprove the quality of tobacco because soil nutrients releasing is not coincident withthe nutrients absorb rules of tobacco, and the leaf fertilizer with low cost and higheffect can harmonize the nutrients of tobacco leaf and improve the economic benefitof tobacco under assorting with soil fertilizer.

烤烟生产中，由于土壤养分释放状况与烤烟吸肥规律并不一致，单一的土壤施肥并不能达到改善烟叶品质的目的，而成本低、肥效快的叶面肥可以针对烤烟不同生长发育期各异的养分需求特点，配合土壤施肥，协调烟叶自身营养状况，改善烟叶内在品质，进而提高烤烟经济效益。

The results showed that 177.24 kg·hm^-2 N had been removed by corn harvesting and 1.03 kg·hm^-2 by water and soil erosion, which accounted for 99.42% and 0.58% of the total N removal respectively in treatment with integrated contour hedgerows strip＋contour cropping＋balanced fertilization.

结果表明，在等高种植＋平衡施肥＋等高植物篱条带组合农艺措施条件下，收获玉米带走的氮为177.24kg·hm^-2，占水土流失和收获玉米带走氮总量的99.42％，水土流失带走1.03kg·hm^-2的氮，占水土流失和收获玉米带走氮总量的0.58％；顺坡种植＋农民习惯施肥收获玉米带走的氮仅为120.31kg·hm^-2，占水土流失和收获玉米带走氮总量的79.36％，而水土流失带走31.29kg·hm^-2的氮，占带走氮总量的20.64％。

The soil nutrient regimes in different townships were presented based on the survey of the soil nutrients, and some proposals are made for judicious application of fertilizers and soil amelioration.

结果反映了文昌市不同地区养分状况，提出了合理施肥及改良利用的建议，为今后土壤养分资源的综合评价和科学施肥提供了基础支持。

Adopting ameliorated flat arrow-like opener, the machine can cut off the continuity of soil macropore flow; form a compact fertilizer strip on the base of ridge, which can decrease nitrogen leaching by macropore flow. The machine makes use of single-disk to form ridge on the fertilizer strip.

采用改进后的平底箭铲式施肥开沟器能够阻断土壤中大孔隙流的连续性，在垄底形成一致密的施肥带，减少了氮肥在土壤中随大孔隙流的淋溶迁移。

This paper took bamboo forest which is in the district of Huangshan in Anhui Province without human disturbance as the research object, making research on dynamic changes of chemical properties and enzyme activities of rhizosphere soil at different growth stages of bamboo, aiming at providing theoretical basis for precise fertilization in root region of bamboo, and improving fertilizer efficiency. At the same time, we made an analysis about the effects of fertilization on bamboo seedlings, and established the DRIS nutritional diagnosis to provide theoretical basis for the management of seedling bamboo nutrition. The main conclusions are as follo...

本文以安徽省黄山区无人为经营毛竹林为研究对象，对其不同生长阶段根际土壤化学性质、酶活性等动态变化进行了研究，以期为毛竹根区精准施肥，提高肥效提供理论参考；同时，分析了毛竹实生苗苗期施肥效应，建立了DRIS营养诊断方法，旨在为指导毛竹苗期营养管理提供理论依据。

The increase has been especially dramatic during the past two decades in the U.S, particularly for sprinkler and drip irrigated systems.
