摘要: 为探究设施黄沙栽培条件下番茄根际温度变化,试验设置黄沙调温栽培(T1)、黄沙地下槽式栽培(T2)和黄沙地上槽式栽培(T3)3种黄沙栽培模式,以平地土壤栽培(CK)为对照,测定空气温度及不同深度(10、20、30 cm)根际温度变化。结果表明,不同栽培模式根际温度与气温变化趋势基本一致,达到最低温和最高温时间均滞后于气温,随根际深度增加达到极值的时间推迟。除T1处理10 cm深根际温度低于CK外,不同黄沙栽培模式在不同深度根际温度均高于CK,T3处理日均温为27 ℃左右,T2处理和T1处理日均温为25 ℃左右,土壤栽培日均温为22 ℃左右。黄沙栽培模式日较差均高于CK,随着根际深度增加日较差减小。由此可知,黄沙栽培模式有利于提高番茄根际温度,在实际生产中可以选用黄沙作为基质进行番茄栽培,以此来解决土传性病害问题。

Abstract: In order to explore the change of tomato rhizosphere temperature under the condition of protected yellow sand cultivation,three cultivation patterns of yellow sand were set up,air conditioning cultivation(T1),underground trough cultivation(T2),aboveground trough cultivation(T3),and flat soil cultivation(CK) was used as the control.The air temperature and rhizosphere temperature of different root depths( 10, 20, 30 cm) were measured.The results showed that the variation trend of rhizosphere temperature and air temperature in different cultivation patterns was basically the same,the time to reach the lowest temperature and the highest temperature lagged behind the air temperature,and the time to reach the extreme value was delayed with the increase of rhizosphere depth.Except the 10 cm deep rhizosphere temperature in T1 treatment, which was lower than CK, the rhizosphere temperature in different yellow sand cultivation modes was higher than CK at different depths.The average daily temperature of T3 treatment was about 27℃ ,that of T2 and T1 treatments was about 25℃ ,and the average daily temperature of soil cultivation was about 22℃ .Daily variation amplitude of yellow sand cultivation models was higher than CK,and it was decreased with the increase of rhizosphere depth.Therefore,the cultivation mode of yellow sand is beneficial to improve the tomato rhizosphere temperature.In the actual production,yellow sand can be used as the substrate for tomato cultivation to solve the problem of soil borne diseases.
