PAM 与尿素混施对渭北旱塬苹果生长及产量品质的影响
Effects of PAM mixed with urea on apple yield and quality in Weibei rainfed highland
摘要
Abstract
With the purpose of understanding the effect of PAM in dryland orchard ,and defining its technical pa-rameters for field application in Weibei rainfed highland .,this study used the 17-year-old fuji apple trees as test materi-al ,employing completely randomized design with two factors and four levels ,with emphasis on the effects of PAM mixed with urea on apple yield and quality .The results showed that the shoot length ,single fruit weight and the fruits’ transect diameter increased with the increase of urea amount .The weight of 100 leaves and the fruit yield increased at first ,and then decreased with the increase of urea amount .The shoot length ,single fruit weight ,the fruits’ transect diameter and the fruit yield increased at first ,peaked at 0 .25 kg per plant ,and then decreased with the increase of PAM amount .The acid content was lower at the rate of 0 .15 kg PAM per plant .Accordingly ,we suggest that the suitable ratio of PAM and urea be 0 .25 kg and 1 .36 kg per plant ,respectively .关键词
