施肥

The content of available nutrients in gleyed paddy soils was influenced byfertilizations.

不同施肥处理对潜育性稻田土壤速效养分的影响不同。

In the gleyed paddy soilsdeveloped from Quaternary Red Clay, there were no significant difference of theamount of total reductive substances and active reductive substances among fivetreatments in the present experiment. This maybe was due to high soil organic matterin the selected soil.

在第四纪红土发育的潜育性稻田中，五个施肥处理间土壤还原物总量和活性还原物含量没有显著差异，可能主要是第四纪红土发育的土壤有机质含量较高的原因。

However, information on agricultural practice to improve this kindof soils is rather scanty. In the present study, field experiments were conducted tostudy on effects of fertilization practices on the physico-chemical properties and thecrop productivity in gleyed paddy soils from the slate in Taojiang county and theQuaternary Red Clay in Ningxiang county, respectively.

本文通过田间小区试验，研究了几种施肥措施对桃江县板页岩母质发育的潜育性稻田和宁乡县第四纪红土发育的潜育性稻田的土壤的理化性质以及作物生产力的影响，以期为这两类退化稻田的改良修复提供依据。

A two-year field experiment was conducted to investigate ammonia volatilization from Gleyed paddy soil in the Taihu Lake region. The experiment was designed to have four N levels 0, 180, 255, 330 kg hm^(-2 and four P205 levels 0, 30, 90, 180 kg hm^(-2, forming six NP combinations (CK-N0P0, LN-N180P90, OPT-N255P90, LP-N255P30, HP-N255P180 and HN-N330P90). Ammonia volatilization was measured with the enclosure method.

在太湖地区乌栅土上，采用田间小区试验连续两年研究了施氮量为0、180、255、330 kg hm^(-2)，施磷(P2O5)量为0、30、90、180 kg hm^(-2)的6个组合（对照N0P0低氮N180P90、优化N255P90、低磷从N255P90、高磷N255P90、高氮N330P90）以及三个施肥时期对稻田氨挥发损失的影响，氨挥发采用密闭室间歇通气法测定。

Rice production and sustainable development for agriculture in China waslimited by poor quality of gleyed paddy soils, such as the accumulation of reductivesubstance, low availability of soil nutrients and declined soil productivity, due to poordrainage. In the past, researches focused more on engineering technology to improvegleyed paddy soils.

潜育性稻田由于其排水不畅，造成稻田土壤通气不良、还原性有毒物质累积、养分有效化过程受阻以及土壤生产力下降等一系列问题，严重影响我国的水稻高产稳产和农业可持续发展，过去的研究仅局限于工程措施改良潜育性稻田，对施肥等农艺措施研究不够。

The fertilization practices exhibited distinct influences on crop productivity insoils developed from different parent materials. In the gleyed paddy soils developedfrom slate, application of NPK organic fertilizer showed the highest rice yield,followed by NPK CaO_2 and specific fertilizer for rice and NPK Si.

主要研究结果如下： 1、供试施肥措施在不同母质发育的潜育性土壤上对提高潜育性水稻土壤的生产力的影响不同，在板页岩母质发育的潜育性稻田上的效果要好于第四纪红土发育的潜育性稻田。

Golden Valley through the construction of agricultural supplies supermarket chains for farmers to provide high-quality low-cost means of agricultural production, and as a platform to carry out the majority of farmers to provide various forms of free services, such as soil testing, fertilization, pest and disease control, science and technology fields, and so on. The second half of 2001, Golden Valley also introduced the "Golden Valley of the green food circulation agriculture projects"(in Hebei, Henan provincial government support), gold-chain of agricultural products distribution center as the carrier, value-added agricultural products for farmers to solve the problem, Lead to a well-off farmers.

金色谷通过建设农资连锁超市为农民提供优质廉价的农业生产资料，并以此为平台开展向广大农民提供多种形式的免费服务，例如测土施肥、病虫害防治、科技种田等。2001年下半年，金色谷又推出了&全国金色谷绿色食品流通兴农工程&（已得河北、河南等省政府支持），以金色谷农产品连锁配送中心为载体，为农民解决农产品增值问题，引领农民走向小康。

A Niu back to the house carefully weighing the Chrysanthemum Fairy "of Ju-song," which finally realize the meaning: of BAI Ju to transplant in March and April Qia head, and more water in May and June ground fertilization, in July August for good root, this September will be open to the chrysanthemum-like hydrangeas.

阿牛回到屋里仔细推敲菊花仙子的《种菊谣》，终于悟出了其中意思：种白菊要在三月移植，四月掐头，五月多浇水，六月勤施肥，七月八月护好根，这样九月就能开出绣球状的菊花。

Manna sugar potentiometric method has been used to determine the boron in foliage spray fertilizer which contained the humic acid.

甘露醇电位滴定法测定含腐植酸叶面喷施肥中硼的含量，用酸度计来指示滴定终点，不需对样品进行处理，方法操作简单，精密度、准确度较高，相地标准偏差小于 1%，回收率在 97%以上。

Fertilization of heavy metal contaminated soils is a practicable technology for mitigating heavy metal content in shoots of leaf vegetables.

重金属污染土壤施肥处理是一种值得推广的降低叶菜有害重金属含量的有效技术。

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。
