刺槐

50Mmol/L NaCl stress had no influence on level of ATP in root of Ginkgo andAilanthus.Level of ATP in roots of Ginkgo,Ailanthus and Robinia decreased greatly under200mmol/L NaCl stress.The extent of decrease of ATP level accord to plant salt tolerance:Ginkgo is more salt tolerance,and ATP decreases more slowly than that of Ailanthus andRobinia.

11.50mmol/L的NaCl胁迫没有引起银杏和臭椿根尖ATP水平的明显改变；200mmol/L的NaCl胁迫引起银杏、刺槐和臭椿ATP水平指数性的衰减，ATP的下降幅度的变化与植物耐盐性一致：耐盐性强的银杏，ATP的下降幅度明显比刺槐和臭椿小。

The above ground biomassof black locust and cryptomeria stands takes a greater percentage of the totalbiomass than that of water fir and chinese fir stands.

在落叶期，水杉的林冠截留率明显较柳杉林小，而和刺槐林相近，但在盛叶期却明显较刺槐林高，而与柳杉林相近。

When big, moderate rain and rainstorm, the Y value size order is always the masson pine pinus elliottii mixed forest＜the wetland pinery＜the wetland pinery＜the locust tree forest＜the locust tree pinus elliottii mixed forest＜the thin forest, to the soil protection effect, the conifer forest is better than broad leaved forest. For annual rainfall erosion, the Y value ordered: Locust tree forest＜wetland pinery＜locust tree pinus elliottii mixed forest＜wetland pinery＜masson pine pinus elliottii mixed forest＜thin forest.

大、中雨和暴雨时，Y值的大小顺序都是马尾松湿地松混交林＜湿地松林＜湿地松林＜刺槐林＜刺槐湿地松混交林＜疏林，对土壤保护效果针叶林优于阔叶林；对于年降雨侵蚀，Y值的大小顺序是：刺槐林＜湿地松林＜刺槐湿地松混交林＜湿地松林＜马尾松湿地松混交林＜疏林。

The effects of growth regulators on regeneration of compound leaves of fast growing Robinia pseudoacacia were studied.

以引进的速生型刺槐的复叶为实验材料，进行离体培养，研究生长调节物质对刺槐复叶的小叶和叶轴再生的影响。

It is suggested that changing light environment is the main factor for inducing leaflet movement of Robinia pseudoacacia, and the rhythmical movement does not attribute to the leaflet movement.

这说明变化的光环境是引起刺槐复叶运动的主要原因，而节律性运动不是刺槐复叶运动的诱导因素。

The paper focuses on the tetraploidy black locust on Loess plaeatu of West Shanxi province, applys steady state promoter method and image processing technology to study the days transpiration water consumption in different weather ,different seasons and different site conditions,has primary analysis on the impact of environment on the transpiration and carries on the calculation to the tetraploidy locust tree by the single leaf water consumption to the single tree water consumption in CaiJiachuan watershed; Uses fast weighing method to measure and analyze the transpiration water consumption of five different herbs under the tetraploidy black locust forest (Capillary Wormwood,Vanilla,Agropyron Sristatum , Common Sowthistle and Medicago Sativa) in short time, in the same and different growcrop,and calculates the average transpiration water consumption per square metres ;the soil colome weighing method was used for determining diumal variation quantity of soil moisture evaporation, analyzing the dynamic variation and caculating the total quantity of soil evaporation water consumption from May to August ; then 5 kind of suppositions about the types of surface vegetation coverage are proposed in experimented site and the total evapotranspiration water consumption are calculated under 5 suppoitions ,aim at providing preliminary theoretic basis for ascertaining the transpiration water consumption of tetraploidy black locust forest,controling standing forest density and optimizing the forest grass deploy on loess plaeatu of west Shanxi province .

本文以两种不同立地条件下的四倍体刺槐林为研究对象，采用了气孔计法对蔡家川流域生长季内不同天气状况下(典型晴天、阴天和半阴天)四倍体刺槐日蒸腾耗水规律、不同季节(生长季初期、中期和末期)的蒸腾耗水规律、两种不同立地条件下四倍体刺槐蒸腾耗水比较以及影响四倍体刺槐蒸腾耗水的环境因子进行初步研究分析，并对四倍体刺槐由单叶耗水量向单株耗水量进行推算；采用经典快速连续称重法对四倍体刺槐林地生长的主要5种草本植物(白蒿、香青兰、冰草、苦苣和苜蓿)短时段内蒸腾耗水规律、不同生长季内蒸腾耗水规律、同一生长季不同种类草本植物蒸腾耗水量进行了比较分析，并且采用面积与重量比的方法推算出了单位面积四倍体刺槐林地几种主要草本植物平均蒸腾耗水量：采用土柱称重法测定了5月份～8月份土壤水分蒸发昼夜变化量、对试验期内土壤蒸发量动态变化作了分析、推算出了试验地5月份～8月份土壤蒸发耗水总量；对试验地地表植被覆盖类型提出了5种假设，推算出5种假设的情景下蒸散耗水总量，旨在为晋西黄土区四倍体刺槐林蒸腾耗水量的确定、林分密度调控以及林草优化配置等提供初步的理论依据。

In the horizontal direction,most of effective root for Black Locustdistributed in 30cm～90cm from stem basal,but it for Arborvitae distributed in 0～30cm.

其中，刺槐有效根长占总有效根长的51.58％，侧柏占58.38％；刺槐有效根干重占总有效根于重的63.01％，侧柏占71.09％；在水平方向上，刺槐有效根系密度呈二次抛物线型分布；侧柏则随距主干距离的增大而减小。

In order to explain clearly the variation status of embryo from tetrapoid Robinia pseudoacacia and fully use the variation resource initiated in the sexual reproduction of TRP in the further improvement of TRP, the classification and vitalities of seed embryos from tetraploid Robinia pseudoacacia were studied. The main results are as follow. According to the cotyledon number, color and plumpness, the seed embryos of TRP could be divided into 5 types: YVT (yellow, very replete,2 cotyledons), YMT( yellow, more replete,3 cotyledons ), YRF ( yellow, replete,4 cotyledons ), GNT ( green, no-replete, 2 cotyledons ) and WNT ( white, no-replete, 2 cotyledons ).

为了阐明刺槐同源四倍体种子胚变异状况及充分利用刺槐同源四倍体有性过程创造的变异资源对四倍体刺槐进行遗传改良，研究了刺槐同源四倍体种子胚类型及其生活力特征，主要结论如下：刺槐同源四倍体种子胚按照子叶数量、颜色及饱满程度，可以划分出5个类型：黄二、黄三、黄四、绿二及白二，所有类型种子胚混合平均单胚重量接近二倍体的1/2。

The study indicates that the content of soil carbon is on the low side because human behavior has a negative effect on sloping cropland. However, the content of every group soil carbon increased drastically by planting Robinia . With the increasing of the time of conservation, the relationship is very remarkable. After 50 years of restoration, the content of TOC, LOC, NLOC and AI in the study plot increased by 271%,174%, 467%, and 271%, respectively, compared with sloping cropland. The increasing speed of NLOC was faster than LOC. It is assumed that the increased carbon by restoration is stored in an inactive form to produce active matter which is necessary for biont. And the soil carbon must keep active to fulfill the balance of carbon dynamic transformation. At initial stages, soil carbon management index increased remarkably.

营造刺槐林可以显著增加土壤碳库各组分含量，并随恢复年限呈显著线性关系，50a时TOC、LOC、NLOC和碳库指数分别较坡耕地增加271%、174%、467%和271%，其中NLOC增加速率略高于LOC，表明植被恢复增加的土壤碳素绝大多数以非活性形态贮存起来，而为了满足生物生长所必须的活性物质来源，土壤碳库必须维持一定的活度状态来满足碳素的动态转化平衡，碳库管理指数在营造刺槐林初期显著降低，随后先增加后降低，与刺槐林生长特性密切相关；但与天然林相比差距仍然较大，恢复50a时TOC、LOC和NLOC仅为侧柏林的49%、34%和61%。

Pseudoacacia and Caragana were significantly (P.05) better than A. fruticosa in pH, lactate content and ammonia-N/total-N ratio, so that their fermentation quality was better. In addition, they were high in crude protein and low in neutral detergent fiber and acid detergent fiber, showing that they were abundant in nutritive components. A. fruticosa was the inferior silage in every evaluation in the experiment. The mixed silage of R. pseudoacacia and Caragana was the best, and the mixed silage with A. fruticosa was not recommendable. There were no obvious changes in the time before and after silaging in nutritive value of these three kinds of plants, it showed that the silage technology was good.

结果表明：刺槐、柠条青贮伺料在pH值、乳酸含量、氨态氮／总氮比值方面均显著地(P.05)好于紫穗槐处理，发酵品质良好，且粗蛋白含量高，中性洗涤纤维和酸性洗涤纤维含量低，营养价值高；而紫穗槐青贮品质在各项评定中均较差；在混合青贮中刺槐和柠条青贮混合品质最佳，与紫穗槐混合的两种混合饲料品质较差；刺槐、柠条、紫穗槐在青贮前后营养品质均无明显降低，青贮饲料品质等级均为良好，青贮效果较优。
