Yinwan 2 was a new pea variety bred by pedigree with the parental combination of Yinwan 1/Hafila under irrigation.The average yield of Yinwan 2 was 5 404.5 kg/hm2and 12.4% higher than of the check Yinwan 1 which was conducted during the period 2009 — 2010 in 2 a 10 point of the multi- point test. The results showed that Yinwan 2 was the semi- leafless,and the growth period,plant height,kernel weight were 96 d,65 cm,26.5 g,respectively. The results also indicated that content of crude protein,starch,lysine,crude fat,ash were 246.3 g/kg,602.9 g/kg,14.0 g/kg,13.7 g/kg,29.5 g/kg,respectively. It is stuitable to plant in the irrigation areas and cold and high humid regions of Gansu province and other similar ecological areas.

通过对白银市黄河沿岸及高扬程灌区小麦生产的品种推广、良种供应体系建设及小麦面积减少现状的调查,提出了一些发展建议及对策,旨在为我市引黄灌区小麦生产决策提供一些依据。

Yinwan 1 was a steady-varieties with outstanding characters bred by Baiyin Institute of Agricultural Sciences in the way of directional geneal selections from hybrid offsprings which was provided by Qinghai Academy of Agricultural Sciences.The average yield of three years was 5 250.00 kg/hm2 and 23.2% higher than that of the Beijing 5 in high moisture and fertilizer regional trials of pea during the period 1999-2001.The result provided showed that the grain contains crude protein 22.34%,amylum 67.24%,lysine 1.8%,crude fattiness 1.36%,ash 2.8%.It is suitable for growing in the every irrigated region of Baiyin and in the same ecology round of Gansu province.

In order to open up and utilize the saline-alkali lands and to select new salt resistant wheat varieties, two varieties Naiyan 3 and Naiyan 8 were planted on different saline-alkali lands in the irrigated areas along Yellow River in Baiyin city in Gansu province, Ninchun 18 and 764 as contrast varieties. The results showed that Naiyan 3 and Naiyan 8 had stronger salt resistance and higher yield than the contrast varieties when they were planted on saline-alkali lands with a salinity of 0.299%~0.786%. When the soil salinity was 0.299%, the agronomic characters of wheat were affected to a light degree, and the yield of salt-resistant varieties was slightly higher than that of the contrasts. When the soil salinity was between 0.299%~0.786%, the growth of wheat was restrained obviously. As the soil salinity increasing, the production increase rate of salt-resistant varieties was higher than that of the contrasts and their superiority was obvious. When the soil salinity was between 0.786%~0.828%, the growth of wheat was restrained seriously. As the soil salinity increasing, the yield of wheat dropped rapidly, and the salt-resistant varieties were superior to the contrasts. But their yield was very low so that they were not suitable for planting.

We observed and surveyed the salt-resistant ability of five crops including wheat,barley,corn,flax and oil sunflower in saline-alkali land and soil salinity in Yellow River irrigating area of central Gansu.The results showed that the salt-resistant ability of barley was the highest.When soil surface salinity was 6.0～10.0 g/kg,barley was restrained lightly or less strongly and the yield was 2070 kg/hm~(2).When soil surface salinity got over 10.0 g/kg,the growth of barley was restrained seriously.The salt-resistant ability of oil sunflower took second place.When soil surface salinity was 3.0～6.0 g/kg,the growth of oil sunflower was restrained lightly or less strongly.When soil surface salinity got over 8.0 g/kg,its growth was affected seriously and oil sunflowev had low or no yield.The salt-resistant ability of wheat,flax and corn was poor.When soil surface salinity was 3.0～5.0 g/kg,strained degree to their growth was light or less strong.When soil surface salinity got 5.0～8.0 g/kg,although some plant could survive,they had almost no yield

Based on the data of TM images, land-use maps and topographic maps, the temporal and spatial patterns of landscape in the Shule River Basin from 1990 to 1999 were investigated. The results showed that the variations in landscape indices were fluctuating: The landscape diversity index and evenness index in the study area increased from 2.934 and 0.883 to 2.973 and 0.895 respectively but decreased to 2.994 and 0.886 from 1994 to 1999 and the variation tendency of dominance was in inversion with them. In the recent 10 years, the transitions of landscape types resulted in variations of landscape pattern in two aspects in the region. On one hand, intensive farmland landscape with a well-equipped irrigation system has been formed near the water resources in the middle and upper reaches of the river basin. On the other hand, with the increase of exploitation intensity of water resources, the natural ecological system had been gradually destroyed and he landscape pattern had changed from highly fragmented a natural vegetation landscape into desertified regions far away from water resources or the lower river basin.

在景泰县芦阳镇进行的天然多功能土壤给养保养剂(TYS)在玉米上的小区试验结果表明,以玉米大喇叭口期追施TYS 360 kg/hm2、尿素240 kg/hm2的处理产量最高,为6 778.6 kg/hm2,较对照(空白)平均增产16.2%,粗蛋白含量为10.67%,较对照平均增加1.47个百分点;同时在白银市、武威市、景泰县进行的TYS在玉米上的大区试验结果表明,玉米大喇叭口期追施TYS 360 kg/hm2、尿素240 kg/hm2,玉米较单施尿素增产3.7%～9.7%.说明玉米追施TYS可降低尿素化肥用量.
