The effect of azotobacter fertilizer on living activity, soil fertility, yield, total nutrient and crop quantity is studied at the different level of using nitrogen .in the calciform soil by the rape potted plant biology analogue experiment, in order that the best scope of valid applying azotobacter fertilizer is determined. It can offer theoretic basis for searching ways of biology controlling to high yields and qualities, optimization directions for products of special compound fertilizer and valid using.

本文通过油菜盆栽生物模拟试验，研究了在不同施氮水平下，石灰性土壤上固氮菌肥料对土壤微生物活性，养分以及油菜的生物产量、全量养分和品质的影响，旨在确定固氮菌肥料有效应用的最佳土壤氮素范围，为探求油菜作物高产优质的生物调控途径及专性生物复合肥的优化配比提供理论依据。

Xin-yuan tea factory in the sword fighting vigorously to develop new Tieguanyin before tea on the joint co-operation of local tea master, in the triangular Yang reclaimed 80 acres of new tea plantations, a year later into 120 acres, is located in Triangle Area-yang quality, adjacent primeval forest, surrounded by mist seasons, plenty of sunshine, surrounded by a natural mountain spring water supply for irrigation, many beneficial insects and birds, have the original ecological environment of the natural conditions; tea garden management personnel responsible, experienced and have the green environmental awareness, all the year round to farmers to buy farm manure fertilizer, collecting forest fertilizer, plant-made pharmaceuticals, or less as far as possible without using chemical fertilizers and pesticides, is currently growing tea is good, at the vicinity of the modeled object Chashan growers.

心远茶厂在剑斗铁观音大力开发新茶园之前，就联合本地制茶能手共同合作，在三角洋开垦80亩新茶园，一年后又投入120亩，地处三角洋优质片区，毗邻原始森林，四季雾气环绕，阳光充足，四周有天然山泉水可供应灌溉，益虫及鸟类众多，具备原始生态环境之天然条件；茶园管理专人负责，经验丰富，具备绿色环保意识，常年到农家收购农家粪便肥料，采集森林肥料，自制植物药品，尽量不用或少用化学肥料及农药，目前茶树长势良好，为附近茶山种植者之仿效对象。

Many growers spend considerable time choosing among sidedressers such as calcium nitrate, sodium nitrate, 30 percent UAN liquid, and 24S UAN liquid.

许多种植者花费了相当多的时间选择侧施肥料，比如硝酸钙、硝酸钠、30％的UAN液体肥料和24S的UAN液体肥料。

Reducing ammonic volatilization and nitrification,using high N use efficiency and low N responsiveness simultaneously are the main approaches of sustainable development in agriculture to improve utilization ratio of nitogen,decrease environmental pollution and waste of resources.

因此如何提高肥料利用率、降低肥料用量，研制高效无污染，成本较低，农民易于接受的新型肥料已成为现代农业科学发展的重大课题[3，4]。

Economic and bionomical benefit can be reached through using controlled-release fertilizers. The most important application of controlled-release of fertilizer is polymer-coated fertilizers.

控释肥料具有重要的经济效益和生态效益，目前世界上应用最多的控释肥料是聚合物包膜肥料。

The NT increase the Gliadin, Globulincontent and decrease the Glutenin, Albumin contents compared with CT.1.3 In NT, 7 days after anthesis and in the sequel, flag leaf NR activityshows higher, photosynthetic ration and transpiration ratio 16 days after 5anthesis and in the sequel higher and have longer continuance ability thanthose in CT.1.4 In NT, total nitrogen contents in crop and fertilizer utilization efficiencyare lower than those in CT.2 The ecology characteristics of wheat field of NT2.1 The contents of hydrolyzable nitrogen,available phosphorus andpotassium in 0-20cm soil layer are all higher in NT fertilization zone thanthose in CT, While the differentiations are in different levels.

肥料利用率免耕各处理均显著低于常规处理。1.5 和常规耕翻处理相比，免耕处理玉米秸秆腐解率无显著差异。冬前是秸秆腐解的主要时期。小麦生育后期肥料对秸秆腐解的促进作用显著，肥料用量与秸秆腐解率存在显著相关性。2 免耕对土壤理化性状的影响2.1 在成熟期免耕施肥区，和常规耕翻处理相比，免耕处理 N3T 对0-40cm 土层碱解氮含量影响不显著。免耕处理 N3T 显著提高了 0-20cm 土层土壤速效磷和速效钾含量，对 20cm 以下土层速效磷和速效钾含量无显著影响。

The WAR of HWAR with lower WAR such as polyacrylic salt graft polymer decreased more slowly at the same fertilizer concentration than that with higher WAR except urea and monoammonium phosphate. But the polyacrylic salt graft polymer with higher WAR could resistant higher fertilizer concentration.

但不同肥料品种对HWAR吸水倍率的影响程度不同：供试肥料中，尿素由于是中性分子，它对HWAR吸水倍率的影响最小，其它肥料对HWAR的影响程度依过磷酸钙、磷酸一铵、硫酸钾、氯化铵、硫酸铵、氯化钾顺序递减。

Too much fertilizer can burn air plants. With most liquid fertilizers 1/4 to 1/2 tsp. per gallon of water applied once a month will keep your bromeliads healthy.

太多的肥料也会伤害到植株，大多数是液体的肥料，1／4－1／2茶匙肥料用水一加仑，一个月施肥一次就可以了。

After two rice-wheat rotations, 11%–13% of applied labeled N remained in 0-60 cm soil (mostly in the 0-20 cm soil); leaching of labeled urea applied in rice season was little (only 0.6%–1.1% of the applied N accumulated in 20-60 cm soil), and the leaching of fertilizer N occurred in wheat season and the beginning flooding period of the next rice season; 47%–54% of applied fertilizer N was lost and ammonia emission and nitrification-denitrification were the main pathways.

水稻季施用的肥料氮向耕层以下移动很少，20—60 cm土层中累积肥料氮仅占施氮量的0.6%～1.1%，主要发生在小麦季及水稻泡田时期，肥料氮损失占施氮量的47～54%，氨挥发和硝化反硝化气态损失是主要途径。

The results showed that 1518kg farmyard manure and 59.9kg chemical fertilizer, equal to 38kg N, P and K pure nutrient, were applied per unit area (667m2) of arable land,and that the nutrient ratio of farmyard manure and chemical fertilizer was 4.9∶5.1 (N∶P2O5∶K2O=1∶0.4∶0.62), and that the total complex grain output per year and the complex output value were 479.6kg and 804.47yuan per 667m2 respectively, and that the manure cost and the pure income from manuring were 148.25 yuan and 716.22 yuan per 667m2 respsctively, and that 12.6kg grain output could be gotten averagely from 1kg nutrient input The main factors affected the manuring effect were topography, cropping systems and crops kinds and manuring quantity from a peasant household as well effected the soil fertility significantly.

结果：平均每667m2耕地投入农家肥1 518 kg，化肥59.9 kg，折氮磷钾纯养分38 kg，农家肥与化肥养分比为4.9∶5.1，N∶P2O5∶K2O=1∶0.4∶0.62，全年粮食复合单产479.6 kg/667m2，复合产值864.47元，肥料成本148.25元/667m2，肥料纯收入716.22元，肥料产投比值5.9，投入1 kg养分产粮12.6 kg。影响投肥效应的主要因素为地势、耕制和作物。农户投肥数量对土壤肥力影响较大。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
