摘 要:【目的】研究低纬高原山区早春马铃薯不同覆膜种植方式下,土壤水分生产率、土壤含水量动态变化、降水与土壤耕作层湿润深度等变化情况对马铃薯产量差异的影响。【方法】以当地马铃薯品种合作88号为材料,试验设置3个处理:T_1处理,等高横向聚土单垄地膜覆盖种植;T_2处理,等高横向平作半膜覆盖种植;T_3处理,以当地顺坡面平作半膜覆盖种植方式为对照(CK)。【结果】T_1处理的土壤含水量、土壤湿润深度和水分生产率极显著高于T_3处理(CK)3.8%~54.8%、2.2~58.1 cm和6.43~11.46kg/m^3。T_1处理的出苗率极显著高于T_3处理(CK)19.6%~22.3%。T_1处理的产量、经济效益极显著高于T_3处理(CK)82.6%~101.3%和130.8%~172.4%。【结论】T_1和T_2处理,尤其是T_1处理可明显促进早春马铃薯生长发育,提高马铃薯产量和水分生产率,经济、生产效益最佳。【Objective】The aim of this study was to study the effects of soil moisture productivity,soil water content,precipitation and wetland depth on the yield of potato in early spring.【Method】Potato varieties cooperation 88 were tested with three treatments,T 1,equal high transverse polygonal single mulching plastic film mulching;T 2,equal high horizontal flattened half-covered planting;T 3,arranging test with slope for half-covered planting(CK).【Result】The results showed that the water content of soils,soil moisture depth and water productivity with T1 treatment were 3.8%-54.8%,2.2-58.1 cm and 6.43-11.46 kg/m 3,respectively,which were highly significant higher than that of T3 treatment;The emergence rate of the seedlings of T1 treatment was19.6%-22.3%,which was highly significant higher than that of T3 treatment with;T1 treatment would effectively improve yield and economic highly significant higher than that of T3 treatment by 82.6%-101.3%and 130.8%-172.4%,respectively.【Conclusion】T1 treatment and T2 treatment could obviously promote the growth of potato in early spring and improve the potato yield and water productivity.
