麦油两熟制一体化高产栽培大田试验结果表明 ,宽幅麦套种花生套期和密度对麦套花生产量作用显著 ,套期效应大于密度穴数 ,高产麦套花生必须适期套种。麦套花生最适套期为麦收前 5 3天 ( 2 8/ 4) ,适期过后 ,套期每推迟 1天 ,花生约减产 14.6kg/hm2 ;适期套种时 ,麦套花生适宜的公顷穴数为 7995 0 ,夏直播花生适宜的公顷穴数为 8715 0。 The results showed that the peanut hedging and density of broad-leaved wheat intercropping had a significant effect on the yield of wheat intercropping, the hedge effect was greater than that of density, and the intercropping of high-yield wheat intercropping peanut should be carried out. The optimum hedge of wheat and peanut was 53 days (28/4) before wheat harvest. After the appropriate period, the peanut reduced yield by 14.6kg / hm2 every time the hedging was delayed. For the proper intercropping, the suitable hectare of wheat and peanut The number of holes is 7995 0, and the suitable number of hectare for summer direct seeding is 8715 0.
