This paper gives introduction on measures of Rooting- zone restriction. The theoretical basis (Above and below ground correlation、Local root nutrition、Growth redundancy)、Rooting-zone restriction to the growth and development of plants、Rooting-zone re- striction RZ...

本文介绍了园艺作物限根栽培的措施和理论，依据地上和地下相关性、根系局部营养生长冗余、限根对植株生长发育的影响、限根的生理反应和作用机制以及限根技术的应用等方面探讨了其在蔬菜栽培中的应用。

Main obstacle reasons in soil of succession planting vegetables in protected cultivation were reviewed from soil maleficent microorganism increment, soil-borne diseases and insect pests to aggravation, soil nutrient imbalance, soil hypo-salinization, soil acidification and plant autotoxicity.

0引言随着我国蔬菜生产的发展，设施蔬菜栽培面积不断扩大，由于设施栽培的特点是采用人工控制，使设施内部形成了一个特殊的生态环境，且多年连作和大量施用化肥，忽视有机肥使用等，使蔬菜生产出现了各种障碍问题，其严重影响了蔬菜生产和农民收益，并成为制约蔬菜生产可持续发展的瓶颈问题。

We have applied the modem educational technology to the teaching of planting courses, such as Vegetable Culture, Fruit Tree Culture and Field Crop Culture, consequently, some ideas are put forward.

在我院选择了种植类专业课程中的《蔬菜栽培》、《果树栽培》、《作物栽培》，对应用现代教育技术的策略进行实践，实践应用后提出了几点反思。

It is hence concluded that properly controlled soil Na2SeO3 application in Typic Dark Brown Forest Soil would be an effective way to cultivate Se-rich forest vegetables and to exploit Se-rich vegetable resources under the quasi-natural conditions of the forest region, except heavily perturbed coarse-textured soil.

初步得出，典型暗棕壤控制施硒是在近自然条件下培育富硒森林蔬菜并获取高富硒生物资源的有效途径；不过，强烈搅动的砂砾质暗棕壤却不利于硒肥保持和植物吸收，不适于富硒森林蔬菜栽培。

The disease of root~knot nematode has been more serious and became a barrier in structure with the increase of vegetable area.

随着种植结构的调整，设施蔬菜栽培面积迅速扩大的同时，根结线虫病发生逐年加重，已成为设施蔬菜可持续生产的一大障碍。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
