Determined by the specific geological background of Longhetun, the characteristics of the soil resources show abundant calcium and leaning to alkaline. Monomial indexes to evaluate the revisal coefficient of soil adapted to karst mountains areas were screened out combined with the function of karst dynamics system and analysis of characters of each factor about fertility in soil. Predigestion model to soil revisal coefficient monomial assessment was established by successful importation of the content of nutrition elements in plant body, latent efficient elements in soil and available thickness of soil in the cranny of epikarst according to the characters that three carriers of soil, soil water and karst water supply nutrition to plants and two layers of foundation consist of surface soil and soil in epikarst cranny, and several types of soil revisal coefficient and weather-soil productive potentiality were calculated, the results show that the soil revisal coefficient was even more practical after modification than before, which make up of innovation of this study.
龙何屯特殊的地质背景条件决定了耕地土壤资源的富钙偏碱的特点,结合岩溶动力系统的作用,系统分析土壤中各肥力因子的特点,筛选出适宜岩溶石山区特点的土壤订正系数评价单项指标,针对研究区存在土壤、土壤水、岩溶水三种载体提供植物营养和表层土、土下表层岩溶带裂隙土两层空间基质的特点,成功引入植物体内营养元素含量、土壤元素隐性有效态含量及土下表层岩溶带裂隙土有效厚度等新参数指标,探讨建立了土壤订正系数单项指标评价简化模型,计算出龙何屯各耕地类型土壤订正系数和气候-土地生产潜力,结果显示修正后的土壤订正系数比修正前更符合实际,成为本研究的创新点。

By the catalyzed of F3H, F3'H and F3'5'H, the biosynthesis of anthocyanins branched three pathway to form pelargonidin, cyanidin and delphinidin separately. DFR, F3'H and F3'5'H are the most important genes for introducing new metabolic branches by genetic transformation to plants that lack some kinds of flower pigments.
花色素苷的生物合成主要由于F3H,F3'H和F3'5'H三个关键酶的作用形成3个分支,最终分别生成橙色到砖红色的天竺葵素糖苷,红色的矢车菊素糖苷和蓝色到紫色的飞燕草素糖苷,因此, F3'H,F3'5'H和DFR基因是利用遗传转化引入花卉植物原本缺乏的花色代谢途径的关键基因。
