摘要
为明确不同土壤水分和施肥条件下,高产高水分利用率的英国红芸豆的耗水特性,试验设置了3种水分处理和2种施肥处理。结果表明:英国红芸豆干物质积累的关键时期是开花期到始熟期;开花期至鼓粒期耗水量呈快速上升趋势,并且鼓粒期时耗水量达到最大;基肥为主因素的英国红芸豆产量大于追肥为主因素的产量;相对于其他灌溉处理,在开花期和鼓粒期分别进行1次灌溉处理的英国红芸豆产量最高。
To identify different soil moisture and fertilizer condition and water consumption characteristics of British red kidney beans, three kinds of water treatment and two fertilizer treatments were set up. The results showed that the key period of dry matter accumulation of British red kidney beans was flowering period to begin to mature period; flowering period to seed filling period water consumption showed a trend of rapid rise, and drum grain period reached the maximum water consumption; base fertilizer factors of plot yield was greater than the topdressing as the main factors; comparied with other irrigation treatments, flowering period and seed filling period for once irrigation had the highest yield.
