| Abstract: |
| In order to select the best mulching pattern for grapes in solar greenhouse at Hexi corridor region, this experiment was conducted at the irrigation experiment station of Zhangye Municipal Water Affairs Bureau where effects of different treatments were investigated on water consumption regularity and grape production in solar greenhouse. The treatments included straw and white mulching, straw and black mulching, white mulching, black mulching and sand mulching. The results showed that different mulching approaches significantly increased soil moisture content. Straw and black mulching treatment resulted in the highest soil moisture content. Soil moisture content could be increased rapidly later by covering separate straws, which significantly improved the soil water storage capacity using straw and mulching treatments. Additionally, compared to the treatment without covering, different covering treatments could increase grape production. In particular, black film and straw covering gained the best yield with a 28.58% increase (P<0.05). White film and straw mulching treatment could reach an increase of 25.53% (P<0.05). Moreover, different mulching treatments could regulate soil temperature. Straw and mulching film treatment was featured with characters as single film and single straw mulching, causing greater increase in soil temperature than straw mulching at early stage, whereas resulting in slower reduction in soil temperature than film mulching at late stage. The regulate capacity of straw and black film mulching was more obvious than that of others. Furthermore, all mulching treatments could improve irrigation water use efficiency (IWUE) and water use efficiency (WUE), achieving the water-saving purpose. Particularly, black film and straw showed the best effect. |
