施肥

Tobacco alimentation and fertilizing research are developed very fast during those 10 years in china.

近10年中国烟草营养与施肥研究有较快发展，施肥以优质、高产、高效、生态、安全为目标，全面进入生产与生态并重的施肥阶段。

Based on Needs analysis and according to the characteristics of the data for rubber tree precise fertilization decision-making, this paper detailed to analysis and design the spatial data and attribute data of rubber tree precise fertilization of state farm, analysised the spatial data and attribute data of rubber tree precise fertilization decision-making and the database structure, then constrcted the corresponding database.

通过需求分析，根据橡胶树精准施肥决策所需数据的特点，对国营农场橡胶树精准施肥空间数据和属性数据进行详细的分析与设计，对橡胶树精准施肥决策需要的空间数据和属性数据进行分析和数据库结构进行设计，并构建了相应数据库。

Still have, grow in its in development process, if discover blade is shown lilac produce curly phenomenon, show excess of nitrogenous fertilizer employ, answer right now decelerate little dose or extend fertilization time; And blade is shown virescent make clear devoid nitrogenous fertilizer again, answer to increase dose appropriately.

还有，在其生长发育过程中，假如发现叶片呈淡紫色并产生卷曲现象，就说明氮肥施用过量，此时应减速少施肥量或延长施肥时间；而叶片呈淡绿色则又表明缺乏氮肥，应适当增加施肥量。

E. traditional irrigation and fertilization, drip-fertigation with shallow planting and hilling up later, and drip-fertigation with deep planting but without hilling up, in this research.

试验设3个处理：常规灌溉施肥处理A，滴灌施肥处理B，滴灌施肥处理C。

The result shows that: a positive correlation is found between the amount of application of chemical fertilizer and some factors, such as farming hours, attitude towards risks, total family incomes and the proportion of agricultural labour and non-agriculturallabour. A negative correlation is found between the amount of application of chemical fertilizer and other factors, such as farmers' educational background, their cognition of chemical fertilizer, and the channel of information. The agricultural incomes and planting areas seem to be not notable inflecting factors.

研究结果表明：户主的从农时间、风险态度、农户家庭总收入、以及劳力与非农比例情况对农户施肥量成正向相关关系；户主的教育程度、农户对于化肥的认知情况、信息渠道、施肥方式、是否施用有机肥、农户对于化肥利用率的认知以及农户对于污染认知程度等因素对农户施肥量成负向相关关系；农业收入和种植面积的影响则是不显著的。

When apply fertilizer quantity is 1.5 to 2 times to the present quantity on bench terrace, Wheat output raise obviously. But the best application rate is 1.5 times to the present quantity namely 75 kg NH4HCO3 +150 kg Ca(H2PO42 per mu.

在黄墡土地区水平梯田上，施肥量达到目前施肥量的1.5到2倍时，小麦产量明显提高，但以施肥量为目前1.5倍(即每亩施75kg碳铵+150kg过磷酸钙)时为最佳。

Most sugars, organic acids, phenolic acids and most amino acids increased significantly with elevated CO_2. The treatment, 950±50μmol·mol-1 CO_2 enrichment for 6 h every day had more obvious effects than the treatment, 950±50μmol·mol-1 CO_2 enrichment for 3 h every day. Levan, sucrose, arginine, oxalic acid, alanine, malic acid, acetic acid, lactic acid cinnamic acid,ρ- hydroxybenzoic acid and benzoic acid increased significantly.

CO_2施肥黄瓜根系分泌有机酸、氨基酸、糖和酚酸的总量增加，上、下午均施肥的处理分泌数量最多；CO_2施肥显著促进了果聚糖、蔗糖、草酸、苹果酸、乙酸、乳酸、多数氨基酸、肉桂酸、对羟基苯甲酸和苯甲酸等组分的分泌；单位鲜重根系分泌糖和酚酸的数量增加，多数氨基酸保持不变或降低，但有机酸分泌规律不一致。

The result showed that the effects were the best using quick-acting fertilizer as the base manure, when fertilizing to the saplings 2 to 3 months before they sprout and to the grown up fruit trees in December.

采用果苗盆栽和大田栽培2种试验方法，在不同时期，施入基肥与追肥后，定期对果树的生长发育情况进行测量，研究速效肥作基肥，不同施肥时期对幼树和成年果树生长的影响；速效肥作追肥，不同施肥时期对果树营养生长、结果和产量的影响；有机肥作基肥，不同施肥方法对产量的影响。

CO2 enrichment improved nutrient uptake, which was indicated by increases in concentrations of minerals and ZT in the bleaching sap. However, the concentrations of GA, ABA and IAA decreased. Twice enrichments a day in the morning and afternoon proved more effective than the morning enrichment only.

CO2施肥促进幼苗对养分的吸收，伤流液中矿质元素、ZT浓度增加，但GA、ABA和IAA浓度降低；与上午CO2施肥相比，上\，下午均CO2施肥的效果更明显。

Based on the data from1981 to 2002 on crop yield, fertilizer application and soil properties of 200 fields in the watershed of Balaton Lake in Hungary, the relationships of fertilizer use to crop yield and soil nutrient content were evaluated.

利用匈牙利Balaton湖流域200多个农场田块1981-2002年的作物产量、施肥量和土壤养分历史资料，分析施肥量和作物产量的关系，探讨施肥量剧减对作物产量的影响。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
