论述了定西在豌豆根腐病研究及抗病育种的进展，介绍了甘肃中部地区豌豆根腐病的主要致病菌是茄镰刀菌Fusarium solani(MarsSacc、豌豆丝囊霉等8种病原真菌复合侵染引起的根腐综合症；通过选育抗根腐病品种是解决问题最经济有效环保的措施，先后培育出了不同生态类型的豌豆品种定豌1号到定豌5号，基本解决了生产中因根腐病导致的减产、绝收现象，这些品种在甘肃中部、宁夏南部的旱地农业生产中发挥了重要作用。

It was illustrated that, in upland yellow-red earth of South Anhui, without fertilization would cause a deficit of 0.474kg/mu of Cl,and a run off 0.7327kg/mu brought about an average of 0.7327kg/mu loss each year.

在皖南旱地黄红壤烟区不施Cl肥状况下，每年每亩耕层土壤有0.474 Kg的Cl损失；随着KCl用量的增加，土壤流失的Cl量也随之增加，亏损值不断降低。

For the understanding of the kinetic variation and distribution of Cl in tobacco area soil of upland yellow-red earth in South Anhui ,soil samples were collected in 4 times of tobacco growth :early winter of 2002,before transplanting in next year, beginning midway, and leaf collecting .

通过对皖南旱地黄红壤烟区进行施Cl处理，施Cl后分别在初冬、次年移栽前、采烤开始、采烤中期、采烤结束后，分五次分别挖土壤剖面取土样；每次剖面层分别取0-20cm、20-40cm、40-60cm、60-80cm的土层土样，同一层同时取4-5点混匀作为一个样品，分析土壤Cl的动态变化。

The total amount of N loss through ammonia volatilization was N 0.37~3.04kg hm^(-2), accounting for1.31%~3.69% of the total N applied to Winter Radish The total N loss through ammonia volatilization enhanced with the increase in N application rate (p.05) and ex-pressed as y=0.1576e(superscript 0.0146x) and y=0.1826e(superscript 0.0112x) respectively.

不同施氮处理，春季累计氨挥发量为N0.67~5.16kg hm^(-2)，占施入肥料N的0.74%~2.24%；秋季累计氨挥发量为N0.37kg~3.04kg hm^(-2)，占施入肥料N的1.31%~3.69%。红壤旱地春秋二季氨挥发量均随施N量的提高而指数递增，其关系式分别为：y=0.1576e(上标 0.0146x)和y=0.1826e(上标 0.0112x)。

The agriculture of this area is rain fed in nature, so its development is greatly restricted by the water resources.

随着国家对食物安全、生态安全、经济安全的重视，旱地农业研究必然提上议事日程。

Under the effect of industry processes and traffic, town top soil shows magnetic enhancement.

在城市工业和交通等人类活动的影响下，城镇表土的磁性较旱地表土增强。

Although effects of nitrogen fertilizer on nitrogen accumulation and nitrate reductase in tobacco leaf had been extensively studied, impacts of nitrogen fertilizer on flue-cured tobacco leaf nitrogen metabolism in dry land and paddy field were not well documented.

试验采用裂区设计，以硝态氮和铵态氮两种氮素形态为主处理、5个供氮水平为副处理，在大田条件下研究了水田与旱地烤烟在团棵、旺长、脚叶采烤、腰叶采烤和顶叶采烤等5个生育期烟叶的总氮浓度、硝酸还原酶和谷酰胺合成酶活性的氮肥效应。

It is conducive to uptake soil nitrogen for flue-tobacco on dryland soil with maize-tobacco rotation before topping (60 days after transplanting) and uptake soil nitrogen for flue-tobacco on paddy soil with rice-tobacco rotation after topping.2 The nitrogen utilization efficiency of rapeseed cake, rice straw and rape straw were 19.5%, 15.5%, 8.1% respectively, and the inorganic fertilizer nitrogen utilization efficiency were 41.1%, 42.7% and 35.7% under the combined application of organic additives and inorganic nitrogen fertilizer. The contribution rate of rapeseed cake, rice straw, rape straw to accumulated nitrogen of flue-cured tobacco were 1.0%, 2.4%, 2.7% respectively by the combined application of organic additives and nitrogen fertilizer. Flue-cured tobacco for organic nitrogen absorption meet with the nitrogen needs laws of high-quality tobacco, indicating that the combined application organic additives and inorganic nitrogen fertilizer reduces the nicotine content of tobacco, an increase of sugar/nicotine ratio and improved the quality of tobacco. In which the role of rice and rape straw is greater than the rapeseed cake can be used as measures to lower nicotine.3 Nitrogen accumulation in flue-cured tobacco with the total nitrogen input was a significant positive correlation during the growth stage of flue-cured tobacco. The total nitrogen input for the 156.3-405.5kg.hm-2, in which the soil nitrogen mineralization capacity account for 22.6%-54.3%, with an average of 34.5%, that is, soil nitrogen mineralization accounted for 1/3 of the total nitrogen input.

旱地轮作土壤有利于烤烟生长前期对土壤氮素的吸收，水旱轮作土壤增加了烤烟生长后期对土壤氮的吸收。2在有机添加物与无机氮肥配施条件下，烤烟对有机添加物中氮的吸收规律基本符合优质烟的需氮规律，其中烤烟对菜籽饼肥、稻草秸秆、油菜秸秆所含氮素的利用率分别为19.5%、15.5%、8.1%，所配施无机氮肥的利用率分别为41.1%、42.7%和35.7%，菜籽饼肥、稻草秸秆、油菜秸秆对烤烟氮素累积量的贡献分别为1.0%、2.4%、2.7%。3不同轮作方式及添加有机物条件下氮素平衡结果显示，烤烟生长期间的氮输入总量为156.3-405.5kg.hm-2，其中矿化氮量为输入总氮量的22.6%-54.3%，平均为34.5%，约为输入总氮量的1/3；肥料氮的利用率为31.4%-42.7%；植烟土壤氮素表观损失率在37.5%-57.2%，平均为46.9%，约为输入总氮量的一半。

Results indicated that under the conditionwhen there is lack of water in the soil, deep ploughing will lead to dec-rease yeild before sowing, deep ploughing will aggravate the dispellingof the soil water when the field is fallow in the summer.

旱地闭口过暑具有明显地保墒作用；耕层经常保持5—10厘米的细土或人工地表覆盖，可大大降低蒸发量，保墒效果显著，并对提高地温、增加土壤有效养分、增加小麦分蘖、促进根系发育、降低冻害、增加产量有明显作用。
