鲜食甜玉米适期播种试验研究

Study on Suitable Sowing of Fresh Sweet Corn

摘要: 开展鲜食玉米分期播种试验，研究武汉地区气候变化对春季及秋季两季甜玉米发育进程的影响，探索出武汉地区春季及秋季甜玉米的最适宜播种期，为指导生产提供科学依据。试验表明，温度及光照是影响玉米生长发育及产量的关键因子，春季4月份之前播种，迟播有利于授粉、灌浆，产量增产显著；秋季玉米宜早播，可在7月中下旬播种。丰产不一定丰收，建议结合鲜食玉米市场行情调整播期，实行分期播种，降低种植风险。

Abstract: Experiments were carried out to study the effects of climate change on the development of sweet corn in spring and autumn in Wuhan. The optimum sowing date of sweet corn in spring and autumn in Wuhan was explored to provide scientific basis for production. The results showed that, the temperature and light were the key factors affecting the growth and yield of maize. Sowing before April, late sowing is beneficial to pollination and grouting, and yields increase significantly. Corn should be sowed early in autumn. It can be sowed on the middle and last ten days of July. High yield does not necessarily have a good harvest. It is suggested that sowing date should be adjusted according to the market conditions of fresh corn, and sowing by stages should be carried out according to local conditions to reduce the planting risk.
