天津板栗品质分析及其立地地质背景研究

Chemical composition analysis and site geological background of Castanea mollissima Blume quality in Tianjin

板栗是低成本、高效益的经济树种,但其品质地域性差异较大。天津蓟州山区自然条件适合板栗种植。本文从板栗品质指标及其立地地质背景,对天津板栗主产区进行了研究分析。研究表明:天津板栗脂肪含量平均为0.75 g/100 g,水分平均为48.78%,可溶性总糖平均为11.53%,蛋白质平均为8.80 g/100 g,维生素C平均为15.18mg/100 g,板栗果实中N、K、P、Mg、S、Ca含量高;板栗主产区地层主要为长城系串岭沟组,岩性以暗色页岩、粉砂质页岩为主,土壤中SiO_2、K、Corg、N、Fe、B、Mn、Ca含量及p H值非常适宜板栗树生长,有利于果实高品质的形成。

Castanea mollissima Blume is a low cost, high efficiency economic tree species, however, due to the strong regional, its quality is very different. The natural condition of the Jizhou mountain area in Tianjin is suitable for the planting of Castanea mollissima Blume, In this paper, Castanea mollissima Blume in the main producing areas of Tianjin province are studied from the chemical composition of Castanea mollissima Blume quality and site geological background. Research shows：the average total flavonoids of Castanea mollissima Blume in Tianjin is 0.75 g/100 g, the average total flavonoids is 8.11 g/100 g, the average water content is 48.78%, the average total sugar is 11.53%, the average protein is 8. 80 g/100 g , and the average vitamin C is 15.18mg,/100g; N, K, and P, Mg, Ca, S, which belong to a large amount of nutrient elements in the soil, are the largest in the fruits of Castanea mollissima Blume; Formation in Castanea mollissima Blume mainareas is mainly the Chuanlinggon formation of Great Wall, litbology of dark shale silty shale; The contents of Si02, K, Corg, N, Fe, B, Mn, Ca, and pH are very suitable for the growth and fruit quality of Castanea mollissima Blume.
