摘要: 为探讨干旱半干旱区旱地覆膜栽培当归土壤温度变化特征及其对当归产量的影响,研究当归覆膜与不覆膜条件下,不同观测时刻、不同土层土壤温度的变化特征及当归产量, 研究结果表明:不同测定位置不同土层温度随气温的变化而变化,膜上温度高于露地温度;不同土层土壤温度的月变化为:膜上土壤温度(A)>膜侧土壤温度(B)>膜间土壤温度(C)>露地土壤温度(CK)。膜上、膜侧、膜间和露地土壤温度随土层深度增加而下降。膜上温度最高,膜上土层温度下降最快。覆膜栽培能增加当归的产量,覆膜栽培产量为2975.80 kg/hm2,平均高于露地栽培16.53%,露地栽培产量为2553.68 kg/hm2,当归覆膜栽培对土壤地温有显著的影响,当归在10cm至25cm土层温度16~21℃时产量提高。

Abstract: An experiment was conducted to explore the effects of dryland film mulching cultivation on the variation of soil temperature and yield of Angelica sinensis. Angelica sinensis was planted under film mulching and in open field with single factor randomized block design. Each treatment was repeated with three times. The variation of soil temperature and yield of Angelica sinensis of different observation times, different-layer outdoor temperature (CK), temperature on plastic film (A), temperature of plastic film side (B), and soil temperature between plastic films (C) were measured. The results showed that the temperatures of different detection locations and different layers varied along with the temperature variation. The temperature on plastic film was higher than that of open field. The monthly variation of soil temperature in different layers was A> B>C>CK. The temperature of plastic film, plastic film side, between the plastic film and open field decreased with the increase of soil depth. The highest temperature appeared on plastic film, and the decreasing speed of its layer temperature was the fastest. The yield of Angelica sinensis increased by film mulching cultivation, and the yield was 2975.80 kg/hm2, which was 16.53% higher than that of open field. Film mulching cultivation had a significant effect on soil temperature, soil temperature between the plastic film was suitable for increasing the yield of Angelica sinensis.
