摘  要：
[目的]本文旨在探索有效改善番茄根际气体环境的通气方式。[方法]在番茄种植垄距地面20 cm和30 cm深处的埋设PVC管,通过鼓风机强制对土壤进行通气。[结果]通气处理后10～50 cm土层的氧气体积分数提高,二氧化碳体积分数显著降低,氧气最高增幅8%,二氧化碳最高下降96.88%,对40～50 cm土层的效果更加显著;番茄根际20 cm和30 cm处脲酶活性平均可提升26.13%和21.71%;番茄的生物量、株高、茎粗均有所提升,单株产量最大提高30%,并且成熟期提早10 d。[结论]土壤富氧补气系统能有效改善番茄根际土壤气体环境,提高根际脲酶活性,增加番茄产量,促进番茄早熟。

摘  要：
[Objective] In order to explore physiological mechanisms and drought tolerance of apple rootstock vigorous/dwarfing, the structure and water-transport ability of root system at various soil depth of two common apple rootstock species were investigated, and research was aimed to provide technical support for fruit production management. [Methods] Vigorous rootstock Malusmicromaluand dwarfing rootstock M9 T337 were used as experimental materials. The growth condition, root distribution, and xylem vessel trait of both branch and root system at different soil depth were measured. Hydraulic conductivity of root and branch was determined based on the xylem vessel traits. [Results] Study results indicated that the major parameters including plant height, basal diameter, and the number and length of branch of M. micromaluwere significantly higher than that of M9 T337, and both root biomass and root length density of M.micromaluwith a vertical distribution of 0～60 cm were significantly greater than that of M9 T337 with vertical distribution of 0～40 cm. Vessel diameter and hydraulic conductivity of both root and branch of M.micromalu were significantly higher than that of M9 T337, while vessel density of root and branch was significantly lower in M9 T337, and vessel diameter and hydraulic conductivity of deep roots were greater than that of shallow roots for both species. [Conclusion] M.micromalu possessed more efficient vessels, higher root length density and wider vertical root distribution, which greatly contributed to its vigorous effect and strong drought resistance. The deep root, conducting water absorbing from deep soil, may act as an important factor for improving tree′s drought resistance.
