马铃薯高产高效间套作种植模式研究

Study on Model of High-yield and High-efficiency about Potato Intercropping or Interplanting with Other Crops

以本地优良马铃薯品种"米拉"的脱毒种为主体作物,采用马铃薯套玉米间秋白菜、马铃薯间春大白菜套葱、马铃薯套唐菖蒲、马铃薯套半夏、马铃薯间折耳根、马铃薯套玉米间胡萝卜6种种植模式,进行试验研究,结果表明,马铃薯套玉米间胡萝卜模式的投入产出效果最佳,其产投比和纯收入最高,分别为2.937和1278.79元/667m2,可大面积推广。马铃薯套玉米间秋白菜、马铃薯间春白菜套葱、马铃薯间折耳根产投比在2.1912～2.4071之间,可在城郊及集镇附近推广应用。

Good potato variety without virus named 'Mila' was selected as the main crop of this test. 6 kinds of plant models were used in this experiment, there are the model of potato interplanting with corn intercropping with Autumn Chinese cabbage(PCAC), the model of potato intercropping with Spring Chinese cabbage interplanting onion(PSCO), the model of potato interplanting with gladiolus, the model of potato interplanting with tuber of pinellia, the model of potato intercropping with Zheergen(PZ) and the model of potato interplanting with corn intercropping with carrot(PCC). The result show that the efficiency of PCC is the best, the ratio of output and input is the highest, the net income is the biggest of all treatments. the ratio of output and input and net income of PCC are 2.937,1 278.79 Yuan/667m2,the plant model can be spread in big area. The ratio of output and input of PCAC, PSCO and PZ are in the range of 2.191 2~2.407 1, these plant models can be spread in suburbs and the region near town. 
