     在温室盆栽条件下,研究了小麦和苕子在不同土壤(黑淤土、高砂土、白土)上的吸钾特性与钾肥肥效、作物根系参数变化间的关系。 初步结果表明:小麦吸钾能力大于苕子,主要是前者利用土壤非交换性钾的能力较强。

     Fixation power of the various soils differred significantly, the amount of K fixed was closely related to the types and the amount of clay minerals existing in the soil, and physical and chemical properties (clay content, CEC, non-exchangeable K and available K levels). Potassium fixation by soils was negatively correlated with non-exchangeable K content of the soils.
     不同土壤固钾量相差很大,其固钾量与土壤矿物学性质和理化性质(粘粒含量、CEC、非交换性钾和速效钾含量)有关,与原始土壤非交换性钾含量呈显著负相关(不同施钾水平下土壤固钾量与非交换性钾含量之间的相关系数均在-0.6769以上)。

  non-exchangeable potassium
Mobilization of non-exchangeable potassium and sodium in a calcareous soil during plant growth
      
It is a crude measure of non-exchangeable potassium; the higher the value the greater the potassium reserve in the clay minerals.
      


In order to study potassium uptake characteristics of vegetable crops, greenhouse seedling exhaustive experiments with 8 species ( radish, rape, three-colored amaranth, cucumber, tomato, cauliflower, chilli and celery)were conducted in two calcareous soils of different fertility.

本文选用8种蔬菜作物在两种石灰性土壤上进行幼苗耗钾试验,以探讨不同蔬菜作物在苗期的吸钾特点。试验结果表明,各种蔬菜作物吸钾和耐钾饥饿的能力有明显的差异。在耗钾试验中,作物吸收的钾绝大部分来自土壤非交换性钾,其中 1M热HNO_3一次不能提取的非交换性钾部分最高可达55%,其数量随种植次数及作物吸钾总量的增长而提高。

This paper deals with the potassium status and K-bearing

本文研究了我国南方一些土壤的钾素状况及其含钾矿物。结果表明,土壤含钾矿物的含量和种类因成土母质和土壤发育程度而异。花岗岩发育土壤的含钾矿物随粒径增大而增加(>50μ除外),沉积岩发育的土壤情况相反。土壤的非交换性钾与云母类矿物含量呈较好的相关性(r=0.669 ̄*),交换性钾与土壤CEC呈极显著正相关(r=0.808)。不同粒级对土壤全钾量贡献不一,花岗岩发育土壤的全钾量主要集中于10—50μ和>50μ粒级中,沉积岩发育土壤的全钾量主要集中于<2μ和2-10μ粒级中。

Studies on the pot experiments with three different potassium supply soils indicated that wheat had stronger ability of utilizing soil nonexchangeable potassium and much higher utilization rate of potassium fertilizer than vetch. The significant differences of root physiological perameters were in the total and active absorption surface areas which were affected by soil potassium supply condition and hud markedly positive correlation with total uptake of soil potassium and shoot yield. There was also a significant correlation between the root activity, root weight and soil potassium uptake of the same crop. The cation exchange capacity of unit root weight of wheat was smaller than that of vetch, which wasn't strikingly varied in the different potassium supply soils.

在温室盆栽条件下,研究了小麦和苕子在不同土壤(黑淤土、高砂土、白土)上的吸钾特性与钾肥肥效、作物根系参数变化间的关系。初步结果表明:小麦吸钾能力大于苕子,主要是前者利用土壤非交换性钾的能力较强。这两者根系的总活跃吸收表面积间的差异表现最为明显,并且与作物吸钾量、生物产量间呈显著正相关。此外,不同土壤上同种作物的根系生物产量、根系活力与作物吸钾量间也呈正相关。单位根重的阳离子交换量:苕子>小麦,它受土壤供钾状况影响较小。不同供钾水平土壤上,钾肥肥效均以小麦优于苕子,钾肥利用率也以小麦较高。
