宜阳县大蒜种植的气候条件及对策研究

Climatic Conditions and Countermeasure Research of Garlic Growing in Yiyang County

依据大蒜的生物学特性,选取宜阳县1959—2008年气温、降水和日照这3个对大蒜种植影响最大的气象因子,分析其变化特点。结果表明:气温升高、日照时数增多是宜阳县发展大蒜种植的有利因素。大蒜在宜阳县生长发育关键期温度适宜,蒜头发育期光照充足,花芽分化期水分充足,非常适宜大蒜的种植,并针对该地区幼苗冻害、膨大期旱害、生长期病害等情况提出对策。

Based on the biological characteristics of garlic,the paper se.lected annual temperature,precipitation and sunshine three pairs of meteorological factors which greatest inpact on garlic planting in Yiyang County from 1959 to 2008, analyzed the changes its characteristics. The results showed that temperatures rising and sunshine hours increasing were the favorable factors of garlic planting in Yiyang County. Suitable temperature in garlic developmental critical period,sufficient light in garlic growth and sufficient water in flower bud differentiation were very suitable for garlic cultivation. Proposed countermeasures aiming at seedling damage, swelling of drought victims and growing season diseases in the region.
