欠水年型下不同覆盖种植方式对马铃薯田土壤水分及产量的影响
Effects of Different Mulching and Planting Methods on Soil Moisture and Yield of Potato Fields in Water-deficient Years
摘要
Abstract
A field experiment was conducted with four treatments:semi-film flat cultivation(T1),maize straw residue mulching(T2),all-film ridge cultivation and side sowing(T3),and micro-furrows on all-film ridge(T4),using open-field flat planting as the control(CK)in order to examine the responses of soil moisture,single-plant productivity,yield,and water use efficiency to different mulching practices in a dry year and thereby screen out an optimal potato cultivation pattern adapted to semi-arid areas.Straw residue mulching increased the 0-100 cm soil moisture content by 1.25 percentage points,increased the fresh potato yield by 22.79%,increased the marketable tuber percentage by 11.21 percentage points,and increased the yield and value of marketable tubers by 53.39%and 36.49%,respectively,when compared with the control open-field flat planting.Compared with the control,the 0-100 cm soil water content was increased by 1.68-2.44 percentage points under the plastic film mulching treatments,and the fresh tuber yield per plant,marketable tuber yield per plant,and marketable tuber percentage were significantly improved.The micro-furrows on all-film ridge per-formed best under drought conditions,with fresh potato yield reaching 19 329 kg/ha and water use efficiency of 4.46 kg/mm.The fresh potato yield increased by 11.51%compared with semi-film flat cultivation and by 60.03%compared with the control open-field flat planting.The marketable tuber percentage,marketable tuber yield and output value were all significantly improved.The use of mulch cultivation in semi-arid areas in water-deficient years can exert a moisture conservation effect and improve the productivity and marketability of individual potato plants.In the mulching film mulching mode,although the moisture conservation capacity of micro-furrows on all-film ridge is weaker than that of semi-film flat cultivation,the yield,economic benefits and water use efficiency are significantly improved,and it could be used as the preferred cultivation method in semi-arid potato production areas.关键词
