为了明确适合花生生长获得高产的土壤类型,采用箱栽的方法,研究了不同质地土壤(砂土、壤土、粘土)对花生光合特性及干物质积累分配的影响.结果表明,花生单株叶面积、功能叶叶绿素SPAD值、净光合速率和植株总干物质重在生育前期表现为砂土>壤土>粘土,在生育后期则表现为壤土>砂土>粘土.砂土有利于花生前期光合物质积累,壤土则在整个生育期内均有利于花生光合物质积累,而粘土则在整个生育期内均不利于花生光合物质积累.壤土花生各器官干物质分配比例较粘土和砂土合理.壤土的荚果产量显著高于砂土和粘土.
The paper explored the effect of soil texture on photosynthetic traits and detribution of dry matter accumulation of peanut,in order to explicit the suitable soil texture appropriated for high-yielding peanut cultivation.The soil texture including Sandy soil,Clay and Loam,and the experiment were implemented in box plant method.The results showed that the early period of peanut growth and development is Sandy soil>Loam>Clay and the later period is Loam>Sandy soil>Clay on Leaf area per plant,Functional leaf chlorophyll content,Net photosynthetic rate and Distribution of dry matter accumulation of peanut.Sandy soil is in favor of early period of photosynthetic matter accumulation,Loam is in favor of whole period,and Clay is not conductive to the whole period.Loam is more suitable than Clay and Sandy soil on distribution ratio of peanut organ dry matter accumulation.Loam has a higher pod yield than Sandy soil and Clay.
