1990年9月农业部在山东召开的全国玉米生产会议上提出大力推广紧凑型玉米之后,我们于1991年在全省范围内组织了29个点次的紧凑型玉米新组合的多点联合试验和小面积生产示范,取得了较好效果,初步显示了紧凑型、半紧凑型玉米的增产作用和在我省的推广前景。一、可喜的苗头参加联合试验的有省内外选育的紧凑型、半紧凑型新组合(中、早熟种)共14个。从试验结果来看有三个明显的特点: 1、有一批组合比当前拉广种显著增产。中熟种增产15％以上的有成单14、仁单8号、掖单13、成单11
After the Ministry of Agriculture proposed to promote compact corn at the National Corn Production Conference held in Shandong in September 1990, we organized 29 point-by-point multi-point joint trials of compact new corn combinations in the province in 1991 and Small-scale production demonstration, and achieved good results, initially showed the compact, semi-compact corn production and promote the promotion prospects in our province. First, the gratifying signs To participate in joint trials of both domestic and foreign selection of breeding compact, semi-compact new combinations (medium and precocious species) a total of 14. Judging from the test results, there are three distinct characteristics: 1. There are a number of combinations that have significantly increased output compared with the current wide variety. More than 15% increase in mature varieties into a single 14, Jen No. 8, Yeda 13, into a single 11
