摘要
在分析当前河南省小麦生产发展中的技术问题的基础上,针对河南省小麦进一步增产途径、合理播期确定、整地和播种质量、足墒播种以及晚霜冻害问题进行了讨论,提出了强化中期管理增加穂粒数、选择适宜播期下限播种、确保整地和播种质量(尤其要强力推广镇压措施)、实施抗逆栽培、浇足底墒水节水栽培和正确认识半冬性、弱春性品种抗晚霜冻能力、做好晚霜冻后管理的理念和技术措施。
Wheat is the first food crop in Henan province,of which production plays an important role in ensuring food security in China.The paper focused on the discussion of yield increase way,appropriate sowing date,land preparation and sowing quality,late frost disaster,etc.based on analysis of key technique problems in development of wheat production in Henan province.The ideas and techniques of increasing grain number by strengthening management in mid-growth,selecting suitable sowing date,enhancing quality of land preparation by pressing,implementingwater-saving and stress-tolerance cultivation were proposed.
