Abstract:

To increase the soil temperature and solve the soil environment deterioration of early spring greenhouse in Heilongjiang, straw+ cow manure, straw+ horse manure, straw+ sheep manure and straw only were applied to the early spring soil of ‘Qianxi’ tomato greenhouse, respectively. The effect of different straw compound organic ferment materials bio-reactors on soil temperature, soil physical and chemical characters, enzyme activity, microbial community structure were investigated. The results showed that, compared with the control, all treatments decreased the soil pH, and significantly increased the soil temperature, content of EC, alkali-hydrolyzed nitrogen, available potassium, organic matter and sucrase, urease, phosphatase and catalase enzyme. Soil temperature of 20 cm deep increased significantly under straw bio-reactors treatments, especially in the straw+ sheep manure (YGH) treatment. Straw+ sheep manure (YGH) treatment improved the content of available phosphorus in soil by 2 times as compared with the control. Four soil enzymes of straw+ sheep manure (YGH) treatment were at the highest level, which was 91.9%, 220%, 18.5% and 7.3% higher than the control, respectively. The microbial diversity index of the treatments was significantly improved compared with that of the control, and followed the same rule: straw+ sheep manure (YGH)> straw+ cow manure (NGH)> straw +horse manure (MGH)> straw (JG)> control (CK). The utilization ability of the straw+ cow manure (NGH) and the straw+ sheep manure (YGH) on six carbon sources were the strongest, which were significantly higher than that of the other treatments. Based on the principal component analysis and cluster analysis, the effect of straw compound organic ferment materials bio-reactors on tomato greenhouse soil was divided into 4 grades, the order was: YGH, NGH, MGH and JG, and CK. The application of straw compound organic ferment materials bio-reactors could improve soil environment, and straw+ sheep manure (YGH) is the best compound organic ferment material.
