Effects of no- till in the different cover on conditions on crop yield in different cover on conditions were studied in dry land in the middle of the Loess Plateau, DingXi. Results showed that under the no-till form, Pea general increase output, agricultural input costs have decreased significantly , the average saves 810 Yuan / hm2; Under the different cover condition, the net income separately increases 1175.45, 1682.70, 968.25 Yuan / hm2, the economic efficiency is obvious.

本文通过在定西旱地农业地区实施保护性耕作，对免耕在不同覆盖条件下的豌豆产量进行了试验研究，结果表明：在免耕措施下，豌豆产量普遍增加，农业成本投入得到明显降低，平均节约810元/hm2；在不覆盖、秸秆覆盖和地膜覆盖的条件下，纯收入分别增加1175.45、1682.70、968.25元/ hm2。

The proper planting density should be 1 m × 0.3 m and 0.3 m × 0.3 m for land under broadleaf crown and shady droughty land respectively. If the havelock equipment in field was used, seedlings with 15-20 cm for height and 0.30 cm for diameter should be selected for cultivation, with the density and transmittance being 0.3 cm × 0.3 cm and 50% respectively.

林冠下栽植和山垅旱地造林的适宜密度分别为1 m×0.3 m和0.3 m×0.3 m；若利用农田庇荫设施栽培，应选用苗高15~20 cm，地径0.30 cm以上规格的苗木栽植，栽植密度为0.3 m×0.3 m，遮阳透光率在50%左右。

For the mountainous sites, land under the crown of broadleaf at grade Ⅰ or Ⅱ stands, as well as eastward shady land would be preferential, and super seedlings of grade I or II with 21-25 cm for height and 0.40 cm for diameter should be selected for cultivation.

若利用山地经营，可选择在Ⅰ、Ⅱ类立地的残次阔叶林林冠下或地形隐蔽、东向的山垅旱地，采用苗高21~25 cm，地径0.40 cm以上的Ⅰ、Ⅱ级优质苗造林，残次阔叶树要求林冠透光率在55%左右。

On mountainous sites, grade Ⅰ or Ⅱ stands including land below the crown of the secondary broadleaf forest and the Chinese-fir plantation or east-facing, shady dry land could be considered for the plantation. The transmittance of crown in the areas should be 55%~60%. One-year-old high quality seedlings above 25 cm tall and 0.25 cm in diameter near the ground-level should be used. For high-yield, field cultivation, shading facility should be considered and seedlings of taller than 15 cm and greater than 0.15 cm in diameter near the ground should be applied. The appropriate density and sunlight transmittance ought to be 30 cm×30 cm and 50%, respectively.

结果表明，利用山地种植，选择透光率为55%~60%的Ⅰ、Ⅱ类立地的残次阔叶林和杉木林冠下，或地形隐蔽、东向的山垅旱地，选用苗高25 cm以上、地径0.25 cm以上的1年生优质苗木造林；利用农田进行庇荫设施高产栽培，应选用苗高在15 cm以上、地径0.15 cm以上规格的苗木栽植，适宜栽植密度为30 cm×30 cm，遮阳透光率在50%左右。

In the classification of weed types on dry farm land, the diversity of ecological conditions is of greater significance than dominant crops.

在划分旱地农田杂草类型时，环境条件的差异比栽培作物具有更重要的指示意义。

In the false color composite image of TM7, 4 and 2, the dry farm is lurid, and is regular in the geometric outline.

旱地在TM1-4波段反射率较高，在TM5、7波段，反射率逐渐降低，在TM7、4、2合成图像上，呈米黄色，且有规则的几何外形，也较易区分。

The change of soil quality in the water~irrigated farm, dry farm and vegetable plots is mainly depended on the mans management and input level. And in the good tillage and high input farmlands the soil fertility quality is obviously increased.

水浇地、旱地和菜地土壤肥力质培的变化主要取决于人为管理和投入水平，耕作精细、投入较高的土地，其土壤肥力质量有明显的提高。

Methods To capture rodents with trap － night for rodent specimen collection and classification at the sameperiod of each month from 1986 － 2001 ill residential area, rice field and dry farm land.

1986～2001年每月定期在住宅、稻田、旱地3种生境采用夹夜法调查，收集鼠类标本，分类鉴定，统计鼠密度和鼠种组成。

Results There were 8 rodent species in Yuqing county. RatLus norvegicus was the dominant species among domestic rodents, with 83.97 percent; Apodemus agrariuswas the dominant species in rice field and dry farm land, with 95.16 percent.

结果： 余庆县家柄鼠和农田鼠种有8种，褐家鼠为家栖鼠优势种，占总捕鼠数的83.97％；黑线姬鼠为稻田、旱地耕作区优势种，占总捕鼠数的95.16％。
