摘要
为转变传统种植观念,因地制宜变换种植模式,特进行了马铃薯、玉米带型密度套种试验,马铃薯、玉米品种分别选用希森6号、并单16号,以马铃薯、玉米双行套双行2 m为一带,设置3种套种密度,马铃薯、玉米单作为对照,分析不同套种密度下马铃薯、玉米的产量及经济效益。试验结果表明,在玉米、马铃薯双行套双行2 m套种带型模式下,在D1套种模式下,玉米单产1071.4 kg/0.067 hm^(2)、马铃薯单产2114.9 kg/0.067 hm^(2),较玉米、马铃薯单作单产838.8 kg/0.067 hm^(2)、2102.7 kg/0.067 hm^(2),分别增产27.7%、0.6%,套种效益1625.7元/0.067 hm^(2),较玉米、马铃薯单作效益1514.4元/0.067 hm^(2)、1213.5元/0.067 hm^(2)分别增加7.3%、34%,经方差分析,处理间产量和效益均达极显著标准。综上所述,采用玉米、马铃薯双行套双行2m带型模式,玉米密度4800株/0.067 hm^(2),马铃薯密度3700株/0.067 hm^(2)时,单位面积产量最高,效益最好,同时套种下的品种选择很重要,即玉米需尽量选择低秆品种,马铃薯选择早熟品种为宜。
In order to change the traditional planting concept and change the planting mode according to local conditions,a potato and corn belt type density interplanting experiment was specially carried out.Potato and maize varieties were selected as Xisen No.6 and Bingdan No.16 respectively.The area is 2 m in double rows of potatoes and maize,and three interplanting densities are set.Potato and maize single cropping is used as controls to analyze the yield and economic benefits of potato and maize under different interplanting densities.The experimental results showed that under the intercropping belt pattern of maize and potato with double-row and double-row 2 m,under the D1 intercropping mode,the yield of maize is 1071.4 kg/0.067 hm^(2)and the yield of potato is 2114.9 kg/0.067 hm^(2),which are 838.8 kg/0.067 hm^(2)and 2102.7 kg/0.067 hm^(2)for maize and potato.The yield increased by 27.7%and 0.6%respectively.The intercropping benefit is 1625.7 yuan/0.067 hm^(2),which is 7.3%and 34%higher than the maize and potato single cropping benefits with 1514.4 yuan/0.067 hm^(2)and 1213.5 yuan/0.067 hm^(2)respectively.The yield and benefit reached the extremely significant standard by variance analysis.In conclusion,when the maize and potato double row set double row 2 m belt model is adopted,the maize density is 4800 zhu/0.067 hm^(2),and the potato density is 3700 zhu/0.067 hm^(2),the yield per unit area is the highest and the benefit is the best.At the same time,the selection of varieties under interplanting is very important,that is,the low stalk varieties of maize should be selected as far as possible,and the early maturity varieties of potato should be selected.
