Effects of Biochar Application During the Non-irrigation Season on Soil Structure and Hydrothermal Characterstics in Drip Irrigated Cotton Field
This study aimed to investigate the effect of biochar application on the soil hydrothermal characteristics and three-phase structure in the cultivated layer of drip irrigated cotton fields during the non-irrigation season. Five biochar application amounts
15 (B1)
30 (B2)
45 (B3)
60 (B4) and 0 (B0) t/hm2
were set to analyze their effects on the three-phase structure
total porosity
soil temperature and soil moisture content of topsoil (0-40 cm) in non-irrigation season of drip irrigation cotton field in Xinjiang. After the non-irrigation season
compared with the control
the soil solid volume decreased by 2.58%~10.74% and the total porosity increased by 3.38%~12.05%. At the same time
the soil moisture contents of carbon application treatments increased by 1.07%~2.65% compared with the control. The soil thermal conductivity decreased
and the soil thermal insulation effect increased. The minimum temperature of soil plough layer in non-irrigation season increased by 0.34~2.15℃
and the maximum temperature difference decreasedby 0.47~2.14℃. In addition
based on the above soil structure and hydrothermal characteristics of principal component analysis
the highest comprehensive score was B3
followed by B2. In conclusion
biochar application in non-irrigation season was beneficial to improve soil three-phase structure
increase soil total porosity and enhance soil moisture and heat preservation ability. The best application amount of biochar in non-irrigation season of drip irrigation cotton field in Xinjiang should be 30~45 t/hm2.
