摘要:

为优化蓝果树追肥技术,本研究系统探究了肥料种类、单株施肥量和施肥时间对三年生蓝果树生长及光合特性的影响。结果表明,生长指标方面,处理9(单株70 g尿素+6月上旬施肥)表现最优,株高、地径、冠幅月均生长量分别达12.12 cm、2.74 mm、22.60 cm,显著(p0.05)高于有机肥处理。光合特性方面,叶绿素含量最高的组合为处理5(单株70 g复合肥+5月上旬施肥),净光合速率最高的组合为处理4(单株60 g复合肥+4月上旬施肥),蒸腾速率最高的组合为处理2(单株200 g有机肥+5月上旬施肥)。三年生蓝果树快速生长期的最优追肥组合为单株60~70 g复合肥或单株70 g尿素+6月上旬施肥。

Abstract:

To optimize top-dressing techniques for cultivated Nyssa sinensis Oliv.,this study systematically investigated the effects of fertilizer type,fertilization rate per plant,and fertilization time,on the growth and photosynthetic characteristics of three-year-old Nyssa sinensis Oliv. The results showed that in terms of growth indicators,treatment 9(70 g urea per plant+fertilization in early June)performed the best,with average monthly growth rates of 12.12 cm in plant height,2.74 mm in ground diameter,and 22.60 cm in crown width,significantly(p0.05)higher than those of the organic fertilizer treatments. In terms of photosynthetic characteristics,the optimal combination for chlorophyll content was treatment 5(70 g compound fertilizer per plant+fertilization in early May),the optimal combination for net photosynthetic rate was treatment 4(60 g compound fertilizer per plant+fertilization in early April),and the optimal combination for transpiration rate was treatment 2(200 g organic fertilizer per plant+fertilization in early May). The optimal fertilization combination for the rapid growth period of three-year-old Nyssa sinensis Oliv. is 60-70 g of compound fertilizer per plant or 70 g of urea per plant plus fertilization in early June.

Key words: topdressing treatment, Nyssa sinensis Oliv., growth, photosynthesis
