摘要：

本研究旨在探究管道输液滴干施肥技术在板栗栽培中的应用效果，特别是其对板栗营养生长及光合特性的影响。选用3年生板栗主栽品种‘燕紫’为试验材料，设置3个施肥时期和3个施肥浓度进行3因素3水平正交试验，以不施肥为对照(CK)，共计10个处理。结果表明，滴干施肥的枝条生长指标较CK处理显著增加，5月上旬(T1)施肥显著影响枝条长度、粗度、节间长，6月上中旬(T2)施肥显著影响枝条粗度；随着施肥量的增加，滴干施肥对板栗叶片光合特性的促进效果增强。通过熵权-TOPSIS法综合评价，T1、T2、T3均施水溶肥N4浓度（35.55 g MS粉+2.775 g尿素+8.025 g磷酸二氢钾+5 L水）的C9处理施肥效果最佳。综上，管道输液滴干施肥技术对板栗营养生长及光合特性具有显著促进作用；C9处理对板栗营养生长及光合特性最为有利。研究结论为该技术在板栗栽培上的应用提供理论依据。

Abstract:

The effect of pipeline trunk transfusion and drip fertilizers on the nutritional growth and photosynthetic characteristics of Chinese chestnut was explored in this paper, with a view to providing a theoretical basis for the application of this technology in Chinese chestnut cultivation. The test was conducted with the 3-year-old Chinese chestnut cultivar ‘Yanzi’ as the material and set up 3 fertilization periods and 3 fertilization concentrations to carry out a 3-factor, 3-level orthogonal test. The test was conducted with no fertilizer as control (CK) and a total of 10 treatments. The results showed that pipeline trunk transfusion and drip fertilizers significantly improved branch growth indexes compared to CK treatment. Moreover, fertilization in early May (T1) significantly affected branch length, thickness, and internode length, and fertilization in early-mid June (T2) affected branch thickness. The promotional effects of pipeline trunk transfusion and drip fertilizers on the photosynthetic properties of Chinese chestnut leaves increased with increasing fertilizer application. Comprehensive evaluation and analysis by entropy weight-TOPSIS method revealed that the C9 treatment with N4 concentration (35.55 g MS powder+ 2.775 g CH4N2O+ 8.025 g KH2PO4+ 5 L of water) of water-soluble fertilizers applied at all the three periods of T1, T2, and T3, respectively, was found to be the best fertilizer application. In conclusion, the pipeline trunk transfusion and drip fertilizers had a significant promotion effect on the nutritional growth and photosynthetic characteristics of Chinese chestnuts; the C9 treatment was the most favorable to the nutritional growth and photosynthetic characteristics of Chinese chestnuts.
