我省常年夏季伏旱,毁茬(麦后)包谷常因“卡脖旱”减产。近几年,郧阳地区广大贫下中农在各级党委领导下,认真总结了与自然灾害斗争的经验,采用麦包套种两熟的耕作制度,即在小麦预留行中套种包谷,提早了包谷播种期,避过了“卡脖旱”的威胁,显著地提高了包谷产量。一般麦包套种两熟,小麦亩产三、四百斤,包谷亩产五、六百斤,两手合计可上千斤,比麦包连作两熟增产300—500斤,而且还有很大的增产潜力,所以深受干、群欢迎,面积发展很快。全地区1975年麦包套种面积16万亩,1977年发展到98万亩。不仅面积扩大,而且套种的质量也大大提高。现根据调查和试验研究结果,把麦包套种的主要技术总结如下。
Summer drought in our province in summer, stubble (after wheat) Valley often due to “card neck drought” cut. In recent years, under the leadership of Party committees at all levels, the vast number of poor and middle peasants in Yunyang earnestly summed up their experience in fighting natural disasters and adopted a two-crop farming system in which wheat was planted as an intercropping system. In other words, Seeding period, to avoid the “card neck drought,” the threat to significantly increase the output of corn. Common wheat package intercropping, wheat mu produce three or four pounds, Baigu per mu five or six pounds, both hands together can be on the kilogram, than the double continuous increase of wheat bread production 300-500 pounds, but also a great yield Potential, so by dry, welcome, area developed rapidly. In 1975, the area of wheat bread covered an area of 160,000 mu in the entire region and reached 980,000 mu in 1977. Not only to expand the area, but also greatly improve the quality of intercropping. Based on the results of the survey and experimental studies, the main technologies of wheat bread intercropping are summarized as follows.
