土壤温度土壤温度soil temperatureturang wendu土壤温度(5011 temperature)土壤温度(地温)影响着植物的生长、发育和土壤的形成。土壤中各种生物化学过程,如微生物活动所引起的生物化学过程和非生命的化学过程,都受土壤温度的影响。土壤温度与农业生产的关系有以下两个方面。直接影响在一定的温度范围内,土壤温度越高,作物的生长发育越快。一年内某时段出现低温或高温,常常给农业生产带来危害。作物的种子必须在适宜的土壤温度范围内才萌发。一般耐寒的谷类作物,种子萌发的平均土温为1一5℃;喜温作物为8一10℃。与气温相比,对种子发芽和出苗的影响,土壤温度要直接得多。但是,土壤温度随地形、土壤水分、耕作条件、天气及作物覆盖等影响而变化。一般作物的根系在土壤温度2一4℃时开始生长,在10℃以上根系生长比较活跃,超过35℃时根系生长受到阻碍。冬麦在12一16℃时生长良好,玉米、棉花等为25℃左右,豆科作物的根系在22一26℃生长良好;马铃薯块茎成熟期30天内,15一27℃是块茎形成的最适上壤温度。过高的土壤温度使植物根系组织常加速成熟,根系木质化的部位几乎达到根尖,降低了根表面的吸收效率。土壤温度低,作物根系吸水缓慢,当气候条件适于蒸腾时,植株地上部分常呈现脱水或缺水。土壤温度过低,常使冬作物的分孽节或根系产生冻害,强低温延续的时间长短和降温及冻融的速度都影响到冻害的程度。土壤温度影响作物的生理过程。在O一40℃之间,细胞质的流动随升温而加速。在20一30℃的范围内,温度升高能促进有机质的输送。温度过低,影响营养物质的输送率,阻碍作物生长。在O一35℃范围内,温度升高能促进呼吸,但对光合作用的影响较小,所以低温有利于作物体内碳水化合物的积累。适宜的土壤温度还能促进作物的营养生长和生殖生长。春小麦苗期,地上部分生长最适宜的土壤温度为20一24℃,后期为12一16℃,8℃以下或32℃以上很少抽穗;冬小麦生长适宜的上壤温度要低一些,24℃以上能抽穗,但不能成熟。间接影响土壤温度影响环境条件中的其他因子,从而间接影响作物的生长发育。土壤温度对微生物活性的影响极其明显。大多数上壤微生物的活动要求有15一45℃的温度条件。超出这个范围〔过低或过高),微生物的活动就会受到抑制。土温对土壤的腐殖化过程、矿质化过程以及植物的养分供应等都有很大意义。土壤有机质的转化也受土温的影响,南方高温地区,有机质分解快;北方温寒地区,则分解慢,土壤中的养料和碳的周转期远比南方要长。所以在高温的南方应加强有机质的累积,而在较寒冷的北方则应侧重于加速有机质的分解,以释放养分。
