低纬高原紧凑型玉米高产栽培技术研究

 通过田间试验探讨云南紧凑型玉米高产栽培技术。研究结果初步说明,在高密度、高肥水条件下,紧凑型玉米表现出高产特性,产量为13570kg/hm²;在此基础上通过改变施肥技术(即施足底肥和种肥,重施穗肥补施粒肥),喷施微肥B,Mg,去雄,人工辅助授粉等措施可使产量进一步提高(增产幅度3%～9%).并提出紧凑型玉米在云南高产栽培的一般技术要求。

Studies on the Cultural Technique of High yield Upright leaf Corn in Low latitude Plateau

The cultural technique of high yield upright leaf corn in Yunnan Provice was explored in this paper.The primary results were as follow:Under compact planting and high content of fertilizer and water conditions,upright leaf varieties of corn presented the characteristic of high yield,and the yield was 13570kg/hm².On the basis of above,yield could be raisd to 3～9 percent with changing fertilization technique,spraying micronutrient Band Mg removing part of the tassels of the plants and supplementarying pollination.The main points of cultural technique of high yield of upright-leaf corn in Yunnan was advanced.
