摘要
为探究不同灌溉方式对甘薯生长的影响,以甘薯品种洛薯17为试验材料,设置无膜畦灌(P0)、无膜滴灌(P1)和覆膜滴灌(P2)3种灌溉处理,测定不同处理的最长蔓长、茎叶鲜重等农艺性状以及单株薯重和产量。结果表明,农艺性状方面,定植后120 d,P2处理的最长蔓长、茎叶鲜重、块根干率和单株结薯数低于P1处理,而T/R、基部分支数高于P1处理;P0处理的茎叶鲜重、T/R、基部分支数、单株结薯数低于P1处理。产量方面,定植后120 d,P2处理的单株薯重、收获产量均低于P1处理;P0处理的单株薯重高于P1处理,收获产量低于P1处理。综合表明,本试验条件下,覆膜处理对甘薯的生长发育和产量形成具有一定的抑制作用;与畦灌相比,滴灌处理更有利于甘薯的生长发育。
To investigate the effects of different irrigation methods on the growth of sweet potato,a field experiment was conducted using the variety Luoshu 17 as test material.Three irrigation treatments were set up:ridge irrigation without mulch(P0),drip irrigation without mulch(P1),and drip irrigation with mulch(P2).Agronomic traits such as the longest vine length,and fresh stems and leaf weight,as well as yield per plant and total yield,were measured.The results showed that,in terms of agronomic traits,at 120 days after planting,the P2 treatment had lower values for the longest vine length,fresh leaf weight,root dry matter rate,and number of tubers per plant compared to the P1 treatment,while it had higher T/R ratio and number of basal branches.The P0 treatment exhibited lower values than P1 in the fresh leaf weight,T/R ratio,number of basal branches,and number of tubers per plant.Regarding yield,at 120 days after planting,both the yield per plant and total harvest yield of the P2 treatment were lower than those of P1.The P0 treatment showed a higher yield per plant but a lower total yield compared to P1.Overall,under the conditions of this experiment,the mulching treatment had a certain inhibitory effect on the growth and yield formation of sweet potato.Compared with ridge irrigation,drip irrigation was more conducive to the growth of sweet potato.
