晚茬大蒜由于播种迟、温度低、影响大蒜正常生长发育,造成抽苔迟,蒜头小,产量低, 出口少,经济效益不高。为此于 1985、86两年我们在外岗、嘉西、朱桥等地进行了不同播期的七组大蒜地膜栽培试验。一、概况试验地点:85年在嘉西竹筱八队、外岗陈周黄东桥生产队、朱桥乡种子场,86年在嘉西竹筱八队、外岗碾子碾东生产队进行。供试品种为嘉定白蒜,前茬单季晚稻。试验设计为不同播期地膜栽培大区对比试验。大区面积0.1～0.2亩。栽培管理:稻收后翻耕整地作畦,施足肥料,基肥和冬春追肥(约占总肥量75％)在整地时一次施下。播种后,立即亩喷“氯麦隆”除草剂5两,隔 Late crop garlic due to late sowing, low temperature, affecting the normal growth and development of garlic, resulting in late bolting, garlic small, low output, less exports, economic efficiency is not high. To this end in 1985,86 two years in our posts, Jiaxi, Zhuqiao and other places were sowing seven different groups of garlic film cultivation experiments. An overview of the test site: 85 years in Jiaxi bamboo Xiao eight teams, outside the post Chen Zhudong Huang Dongqiao team, Zhu Qiao Xiang seed field, 86 years in Jiaxi bamboo Xiao eight teams, outside the post-Roller Mill East production team. Test varieties for Jiading white garlic, single crop before the late rice. The experimental design for different sowing date filming large area contrast test. Area of ​​0.1 to 0.2 acres. Cultivation and Management: After harvesting, tillage and soil preparation will be carried out once the soil preparation is completed, enough fertilizer is applied, basal fertilizer and dressing in winter and spring (about 75% of the total). Immediately after sowing, mu spray “Chloromer” Herbicide 5 two, separated
