Chemical fertilizer is hurtless. The problem of the fertilization comes from unreasonable use.

化肥本身是无害的，有害的是对化肥的不合理施用。

Sum up under the same condition, NT has more advantages than CT onthose indexes of hydrolyzable nitrogen ,available phosphorus and potassiumin 0-20cm soil layer while there are no evidently difference underneath 20cmsoil layer.2.2 In NT fertilization zone and mantle zone, contents of organic matter in0-40cm soil layer are higher than that in CT.

和常规处理相比，免耕施肥区处理 N3T和覆盖区处理 N3TC 在 0-20cm 土层显著提高了有机质含量，其中覆盖区增加效果显著。2.3 和常规耕翻处理相比，成熟后免耕处理在 0-20cm 土层土壤显著降低了土壤容重和增加了毛管孔隙度和非毛管孔隙度，显著提高了土壤总孔隙度。3 免耕对土壤中不同形态氮素以及土壤水分含量变化的影响3.1 土壤铵态氮拔节期至成熟期是免耕处理和常规处理铵态氮显著差异的形成时期。

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 main reasons were as follows: decline in water quality, increment of lake nutrients, developing of eutrophication, special geographical and hydrometeorological conditions, damage of ecological environment and inadequate fertilization etc.

主要原因是：湖体水质下降，营养物增多，富营养化发展迅猛；特定的地理条件和不利的水文气象条件及生态环境遭破坏等是蓝藻暴发的外部因素；不合理施肥及沿湖经济发展过快是蓝藻暴发的加速剂。

Through experiment of 15N microplot showed that: gaseous losses of fertilizer nitrogen was 1.259g·m~(-2), soil residued nitrogen was 1.023g·m~(-2) in Ecological Balanced Fertilization plot, monitored at the same time that chemical nitrogen fertilizer was almost no leakage because there was illuvial layer in the depth of 100～120cm in this area.

通过15N微区试验测得草甸黑土生态平衡施肥区肥料氮气态损失为1.259g·m~(-2)，土壤残留为1.023g·m~(-2)，同时监测到，在该地区100～120cm土层处由于有淀积层的存在，化学氮肥几乎没有渗漏。通过设置不同施氮水平试验，结果显示：大豆播种后，田间土壤氨挥发累积量随氮肥用量增加而增大。

According to these problems on interplanting maize with wheat, scientific and rational techniques for fertilization were made to increase utilizing rate of fertilizer as well as to ensure crop yield, improve quality, lighten pollution, decrease cost and increase efficiency.
