| Abstract: |
| The effects of different amounts of sandy soil amendment on soil water, oat yield and quality were studied in Wuchuan County of Inner Mongolia in 2011. The results showed that sandy soil amendment could improve significantly the soil water content of each layer in 0~60 cm depth, and the amount of 12 000 kg/hm2 was the best. Compared with
CK, the WUE of the amount of 6 000 kg/hm2, 12 000 kg/hm2,18 000 kg/hm2 and 24 000 kg/hm2 increased by 14.50%, 25.70%, 13.28% and 5.86%. Oat yield was significantly affected by sandy soil amendment, and when the amount was 12 000 kg/hm2, the grain yield and biological yield all were the highest and when 18 000 kg/hm2, it was the second. Sandy soil amendment had siginficant effect on crude protein, lysine andβ-glucan content, and the amount of
12 000 kg/hm2 was the best. Excess or lack of application amount were all bad for the increase of oat quality. |
