This paper aims to find out the nutrition characteristics and fertilizer absorption rule of Castor in arid red soil districts under the subtropical climate of Yunnan province, and establish a corresponding fertilizing technology under the condition. It choose the variety TCO-202 of Castor (Ricinus communis L.) as test material to observe and record the dry matter accumulation of each organ as root, stem, foliage and inflorescence, which are in the five critical growth stages as seedling stage、 bud stage、 blooming stage、 filling stage、 maturation stage of Castor {Ricinus communis L. respectively, and measure out the fertilizer absorption amount of nitrogen, phosphorus and potassium.

本文以云南北亚热带气候下的红壤旱地为试验条件，选用蓖麻品种TCO-202为试验材料，通过对苗期、现蕾期、开花期、灌浆期、成熟期五个蓖麻生长关键时期根、茎、叶、花序各器官的干物质积累和氮、磷、钾吸肥量的测定，研究云南红壤上蓖麻的营养特性和吸肥规律；依据蓖麻的营养特性和吸肥规律，结合云南红壤氮、磷、钾的含量与利用效率，制定适合云南红壤上蓖麻栽培的施肥技术研究方案。

Root-derived organic carbon is composed of three compartments: root detritus, root eaudates and root symbionts, which represents a large important and potential C sink in forest ecosystems, The known responses of root derived organic carbon and heterotrophic microbes to elevated CO2 were reviewed. Overall, increases in root biomass, productivity, and exudation indicate an augmentation of C inputs into the soil via roots, although changes in root lifespan are still unclear and may modify this flux positively or negatively, Altogether, changes in root chemistry and morphology that may augment soil C storage under elevated CO2 include decreased N concentration and wider root diameter, Alternately, a shift in rooting depth upwards in the soil profile may increase average turnover rates of root detritus. Effects of CO2 concentration on C qualities of root exudates and root symbionts are the least understood components discussed here, Changes of soil heterotropic microbial activity and community under elevated CO2 still remained large uncertainties.

林木根源有机C包括根东通过根枯落物、根系分泌物和根共生菌周转3条途径向土壤输入的有机C，它是森林生态系统中一个重要的、潜在的C汇，综述了根源有机C与其微生物对CO2浓度升高的响应，虽然对根系寿命的变化尚不清楚，但CO2浓度升高将导致根系生物量、生产量、死亡量和分泌物的增加；同时，CO2升高亦促使根共生菌生物量的增加而增加了共生菌的C归还潜力，表明CO2升高使根源有机C的输入增加了，CO2农度升高情况下，根系化学性质和形态特征的这些变化均有利于增加土壤C的吸存；而根分布深度的降低则对土壤C吸存不利；CO2浓度升高对根分泌物和根共生菌质量的影响研究则极少，CO2浓度升高下土壤微生物活性和群落组成的变化存在较大的不确定性，目前CO2浓度升高下林木根源有机C对森林长期C吸存的贡献仍很不清楚。

The root system in the cortex of the host stem has a few branches and highly simplified stele of original triarch vascular bundles. The haustrium root system, which is from the root system in the cortex of a host stem enters the vascular tissues as finger-like body from the vascular rays and then to become hyphae-like body among the vascular cells.

皮层根有少数分枝，无次生结构，中柱结构高度简化，从胚根的结构可看出其初生木质部原先是三原型的；吸器根从皮层根上发生，进入寄主维管射线中，再进入维管组织内，并形成许多丝状体。
