选育高产稳产、广适多抗、粮饲兼用的强优势杂交种是提高玉米产量的关键性技术措施。四川省及西南玉米产区生态类型多样,土壤贫瘠,大多数土地无灌溉条件,且病虫害较重,干旱等自然灾害时有发生。丘陵区玉米多以间套种植方式为主,为缓解前后作物的共生矛盾,减少对红苕、花生等间套作物的荫蔽,需选育株形较好的强优势杂交种推广应用,以适应间套种植的需要,达到季季高产,全年增产的目的。玉米新杂交种华试3号系四川省农业科学院作物研究所选育的高产
Breeding high-yielding and stable, wide and multi-resistance, combined with the advantages of food and feed hybrid corn is to improve the yield of the key technical measures. There are many ecological types in Sichuan and Southwest corn producing areas, with poor soil quality, most of the land has no irrigation conditions, and pests and diseases are heavier and natural disasters such as drought occur from time to time. In the hilly area, the maize mostly takes the intercropping method as the main method. In order to alleviate the symbiotic contradiction of the crop before and after the crop and to reduce the shading of the crop of the redgrass and the peanut, it is necessary to popularize and apply the strong hybrids with better plant shape, Set of planting needs to achieve high season, year-round production purposes. The new hybrid maize huabao 3 is a high yielding bred by Crop Research Institute of Sichuan Academy of Agricultural Sciences
