【摘要】 为探讨豫东地区大蒜适宜的播种期,给当地大蒜标准化生产提供理论依据,试验以’中牟大白蒜’为材料,安排了18个播种期,测定大蒜不同播期下的出苗率、茎粗、株高、死苗率、抽薹率、二次生长率、蒜薹及蒜头产量等指标,分析播期对大蒜生长发育和产量的影响。结果表明:播种期不同,对大蒜产量和品质的影响也不同。较早播种的大蒜出苗慢,单株生长量有优势,假茎粗、株高大,但是死苗率高,苗期虫害严重,总体产量不高。播种过晚,出苗快,出苗率高,出苗后生长势强,但是适宜生长期较短,二次生长率较高,总体产量低。综合性状结果表明豫东地区10月4日前后播种,蒜头及蒜薹产量高,综合性状优良,为试验推荐的豫东地区大蒜标准化生产适宜播种期。更多还原

【Abstract】 To explore the suitable sowing date of garlic in eastern Henan, and provide a basis for the local garlic standardized production, the experiment was conducted by using’Zhongmou garlic’as material and eighteen sowing dates were designed. The emergence rate, stem diameter, plant height, dead seedling rate,bolting rate, secondary growth rate, the yield of garlic shoot and the yield of garlic bolt were measured so as to study the effects of different sowing dates on the growth and yield of garlic. The results showed that different sowing dates had different effects on the yield and quality of garlic. Sowing too early, the garlic sprouted slowly,and the growth of a single plant was good, the stem diameter was thick, the plant grew high, but the dead seedling rate was high, and the pests were serious at the seedling stage, so that the overall yield was not high.Sowing too late, the garlic sprouted fast, and the emergence rate was high, the plant grew strong, but the suitable growth period was short, the secondary growth rate was high, and the overall yield was low. Taken together, the optimum sowing date for garlic was about October 4 in eastern Henan, the yields of garlic bolt and garlic shoot were high, and the comprehensive traits were excellent, hence it was the suitable sowing stage for the standardized production of garlic in eastern Henan.更多还原
