春马铃薯间套两茬燕麦生产研究

Study on the Production of Intercropping Spring Potato and Two-crop Oat

为研究农业中粮食生产与牧草发展争地矛盾的实际问题,采用马铃薯和燕麦为试验材料,设置了3个处理:马铃薯净作、燕麦净作和马铃薯燕麦间作。结果表明:马铃薯和燕麦间作有利于马铃薯出苗和前期营养生长;马铃薯间套两茬燕麦的经济产量达43450.4kg/hm2,比净作马铃薯经济产量增加28.07%;但间作显著降低了马铃薯块茎产量和商品薯率,间作马铃薯块茎产量仅是净作的32.38%。结果初步表明:马铃薯间套两茬燕麦,一茬收获籽实,一茬收割牧草,这种缓解粮食与牧草生产争地矛盾的粮草间作模式是可行的。

To research of the contradiction between food production and forage grass development, the paper designed three treatments by spring potato and oat： monocropping potato, monocropping oat, and intercropping potato and oat. The resuh represented that intercropping potato and oat was helpful for emergence of seedling and vegetative growth of potato, and the economic outputs of intercropping potato and oat was 43450.4 kg/hm2 that was 28.07% more than monocropping potato. But intercropping potato and oat markedly reduced tuber yield and rate of economic potato, tuber yield of intercropping was only 32.38% of monocropping potato. The research indicated that intereropping spring potato and two-crop oat was feasible to relieve the contradiction between food productions and forage grass development.
