摘要
为探究除草剂和地膜覆盖配套栽培对甘薯生长发育和杂草防控的影响,采用田间试验的方法,研究不同除草剂和地膜覆盖对甘薯田间杂草防控和产量的影响。结果表明,与不施除草剂、无地膜覆盖处理相比,除草剂和地膜覆盖配套栽培对甘薯田间杂草防控、农艺性状和经济性状均有一定的积极效应,而在不同除草剂和地膜覆盖处理中,50%乙草胺乳油×黑色地膜处理对杂草株防效和鲜重防效最好,33%二甲戊乐灵乳油配套透明地膜或黑色地膜对杂草株防效和鲜重防效均最低,33%二甲戊乐灵乳油除草效果不佳;50%乙草胺乳油×透明地膜处理薯块干物率最高,蔓茎干物率、T/R值最低;96%精异丙甲草胺乳油×透明地膜处理鲜薯产量、薯干产量及商品薯率最高;除草剂与地膜覆盖对甘薯杂草防控、农艺性状和经济性状有极显著的互作效应;综合杂草防控、薯块品质等因素,生产上应选用96%精异丙甲草胺乳油和透明地膜配套栽培较为适宜。研究结果为商薯9号杂草防控提供了科学依据。
Field experiments were conducted to study the effects of different herbicides and plastic film mulching on the weeds control and yield of sweet potato.The results showed that the herbicides and plastic film mulching had positive effects on the weeds control,agronomic and economic characters of sweet potato.In the different treatments of the herbicides and plastic film mulching,the 50%acetochlor EC×black membrane treatment had the best effectiveness on the weeds control of sweet potato plant;and fresh weight of the 33%pendimethalin EC×black membrane or transparent membrane treatment had the worst effectiveness on the weeds control;and fresh weight of the 33%pendimethalin EC was not effective on the weeds control.The dry matter rate of sweet potato of the 50%acetochlor EC×transparent membrane treatment was the highest,the dry matter rate of the stem and the T/R value were the lowest.The yield of fresh and dry sweet potato and the rate of commercial potato of the 96%methoprolopamide EC×black membrane treatment were the highest.In addition,the herbicide and film mulching had an extremely significant interaction on the weeds control,economy and agronomic characters of sweet potato.Considering the weed control and commodity value factors,the treatment of 96%methoprolopamide EC×black film is more suitable measure for production.The research results can provide the scientific basis for the weeds control of Shangshu 9.
