Results showed that the topsoil structure of the CK treatment was dense with little porosity developed, and the soil microstructure was sandy granular fabric - granular fabric. In these treatments using chemical fertilizers only, the soil particles did not form soil structure with little porosity, and the soil microstructures in the N, NP or NPK treatment were observed as prophyropectic fabric-fine sand agglomerplasmic fabric, much better than the CK treatment. In those treatments receiving farm manure alone or farm manure plus chemical fertilizers, the quantity of groundmass increased obviously. The soil had a loosen structure, higher porosity, enriched animal and plant residua, iron-manganese nodules and humus, and more micro-aggregates developed. The soil microstructure of the MNPK treatment was pectized-compacted takyric fabric-intertextic fabric, the best microstructure observed among all the treatments.

结果表明：长期不施肥料的CK处理，土壤耕层结构致密，很少有孔隙发育，土壤微结构为结构较差的碎屑聚积状-沙粒聚积状；长期单施化学肥料，土壤颗粒未形成结构体，少孔隙，土壤微结构主要为斑晶胶凝状－细沙粒聚积状结构，土壤结构比CK处理优；长期施用有机肥或有机无机肥料配施的处理，土壤粗颗粒数量显著增加，结构疏松，孔隙量大，动、植物残体丰富，有铁锰结核和腐殖质的形成和微团聚体的发育，土壤微结构类型以MNPK处理最好，为胶凝紧实状－多孔状结构。

In this study, a culture with bitter gourd seedlings (Momordica charantia L.) was conducted in a field (clay slate noncalcareous alluvial soil, Tsp2), located in Wanli, Miaoli. There kinds of composted animal manure (chicken compost, cattle compost, and cattle-hog compost) as well as chemical fertilizer were applied to different treatment plots to investigate and compare their effects on soil fertility and the growth, and on the quality of bitter gourd. One check treatment was also conducted.

本研究系采用设施栽培方式，以嫁接苦瓜苗为品种材料，在苗栗县苑里（黏板岩非石灰性冲积土，水汴头系，TSp2）试验田，分别施用三种不同资材经堆肥化过程而生成之禽畜粪堆肥（鸡粪堆肥、牛粪堆肥和牛猪粪肥），并与施用化学肥料及不施任何肥料的对照组处理比较之，以评估不同来源及组成的有机质肥料对土壤肥力与苦瓜生育及品质产量之影响。

The P.pratensis community is in the phase of herbs and forbs of degraded alpine meadow.At the same time the P.pratensis population is in the dominant spices position,subordinate spices position and company spices position.So,we can replant P.pratensis and other grass seed to change the structure and composition of plant community,improve community environment,cause it to develop to subclimax community succession,reach the stabler state.We can apply fertilizer,improve soil nutrition condition,enable degraded grassland with the link of soil and vegetation system together to reach the stabler subclimax and climax state.

草地早熟禾群落处于高寒草甸退化的禾草杂类草阶段，草地早熟禾种群在群落中处于优势种地位、次优势种地位和伴生种地位，因此，可通过补播草地早熟禾和其他禾草草种，改变植物群落结构和组成，改善群落环境，使其向亚顶级群落演替，达到较稳定的状态；也可通过撒施肥料，改善土壤养分状况，使土壤与植被系统共同作用将退化草地演替为较稳定的亚顶级或顶级状态。

The resultsindicated that the appropriate humidity coerce and little apply fertilizer to anticipate the combination, can repress the invalid tiller, regulate a top and bottom of paddy rice part and the nutrimental backlog of the plant and the seed grain allotment.At the same time, according to the experiment data, water and nitrogen fertilizer coupling function was buil t up originally under this condition of experimenting.

结果表明：适当的水分胁迫和少施肥料组合，能抑制无效分蘖，保证水稻正常生长发育，调节水稻地上下部分植株和籽粒的营养物积累分配，减少了肥料使用量和减少水体污染量，具有较好的环境效应和经济效应。

At Guinea the gold 迪 is second, the section 巴 wait the main 产 area, expert of ground paddy rice in the headwaters than good, rich soil of local chose 6 demonstrates the point, and demonstrate to plant the area 7.4 hectares, demonstrate the point most press be ground cultivation method proceeds, then not apply fertilizer the 料, not the 施 agrochemical , Chinese 杂 hand over the 稻 to express the familiar period more early, yield increase by 1 times above.2004 the dry quarter, expert organize in the section 巴 big area of farm demonstrate, the demonstrate plant the area 130 average and each hectare of hectares, single 产 5.02 ton, create Guinea big area of paddy rice produce tallest record.

在几内亚金迪亚、科巴等地水稻主产区，专家在水源较好、土地肥沃的地方选择了6个示范点，示范种植面积7.4公顷，示范点多数按当地栽培方法进行，即不施肥料、不施农药，中国杂交稻表现熟期较早，产量增加1倍以上。2004年旱季，专家组织在科巴农场大面积示范，示范种植面积130公顷，单产平均每公顷5.02吨，创几内亚水稻大面积生产最高纪录。

Plants with top-dressing showed a marked decrease in the relative ureide-N content from 56 DAS (80%) to 75 DAS (60%).

表施肥料的植株体内酰脲氮的相对含量从播后56天时的80%显著降到75天时的60%。

The results showed that (1) compared with conventional N treatment, the N loss of economic N treatment reduced while NUE and N residue in soil improved under water-saving condition;(2) Use efficiency of fertilizer applied as basal fertilizer was higher than that as top-dressing fertilizer under water-saving condition;(3) The fertilizer N residue rate was from 29% to 41%, and 60% of N residue, which distributed in 1m depth soil concentrated in 0～20cm surface layer;(4) In whole growing stage of wheat, fertilizer N hadn't leach to 130cm depth;(5) NUE of economic N treatment under conventional irrigation decreased by 16.6% compared with the same N treatment under water-saving condition.

结果表明，与常规施氮量处理相比，节水灌溉条件下节肥施氮量处理的氮肥损失率降低，氮肥当季利用率和土壤残留率提高；基施氮肥的利用率高于追施氮肥；土壤肥料氮的残留率在 2 9%～ 41 %之间，分布于 1m土层中，其中60 %以上集中在 0～ 2 0cm土层；在整个小麦生长季内，肥料氮并没有淋洗到 1 30m以下。节肥施氮量在常规灌溉下的当季利用率比在节水灌溉下降低 1 6 6%。

Yunnan Tobacco Research Institute, Yuxi 653100Abstract : In order to investigate the effect of medium and trace elements, organic fertilizer on appearance and internal qualities of sun-cured tobacco, search after some efficient ways to improve the qualities, by adding organic fertilizer in basal dressing and spraying trace elements on leaf surface, the results showed that both organic and medium or trace fertilizer having the effect of increasing output value and yield. Among the experimental treatments, magnesium fertilizer and manure plus rape cake showed the most.

为研究中微肥和有机肥对红土晒烟外观和内在品质的影响，探索提高和改善红土晒烟品质的有效途径，试验在基肥中加入有机肥，和大田生长期在叶面喷施中微量元素肥料，结果表明：施用有机肥的处理与对照相比，产量增加7.3%~20.9%，产值增加8.8%~25.3%，以厩肥＋菜籽饼处理的效果最好；四个喷施微肥的处理其产量和产值均超过了喷清水的对照，其中产量增加6.7%~15.6%，产值增加6.8%~20.5%，以喷施镁肥的增幅最大。
