The correlations between the crown length, wideness and dry weight of Rosa seedling were analyzed.

分析处理苗根颈长、粗和遮荫苗干重之间的相关性，结果表明：遮荫使蔷薇实生苗根颈的伸长的同时也降低了根颈的粗度，从而影响了蔷薇苗后期的生长。

In the greenhouse, tomato seedling was treated with 100 times, 200times and 300times of juice of clover and leek and wood vinegar, and with three different way of treatment: spraying the leaf, sprinkling the root and sprinkling the root combination of spraying the leaf.

在温室中用苜蓿汁、韭菜汁和木醋液三种不同物质以100倍、200倍和300倍按叶面处理+灌根处理、单纯灌根处理和单纯叶面处理三种方式处理番茄苗，测定番茄土壤根际微生物数量并调查番茄早疫病的病情指数和防治效果。

In the greenhouse, tomato seedling was treated with 100 times, 200times and 300times of juice of clover and leek and wood vinegar, and with three different way of treatment: spraying the leaf, sprinkling the root and sprinkling the root combination of spraying the leaf. Then the disease index of tomato early blight was investigated, and the controlling effects was calculated .At the same time, the quantities of microbes around the tomato root were counted.

The results showed that: Under salt stress, it was found the content of Na(superscript +), Cl(superscript -), SO(superscript 2- subscript 4) and Na(superscript +)/K(superscript +) ratio in almond rootstocks organs all went up with increased salt stress and longer treatment days, K(superscript +) content changed irregularly. But K(superscript +) content in every organ of A. commans persicoides rootstocks was higher than that of other two almond rootstocks; the ratio of Na(superscript +)/K(superscript +) in Amygdalus communis L. was higher than that of other two rootstocks.

研究结果表明，盐胁迫下，3种砧木根、茎、叶中Na，Cl，SO(上标 2-下标 4)含量及Na/K比均随盐浓度的增加和处理时间的延长而增加，K含量变化规律不稳定，但桃扁桃根、茎和叶片中K略高于其他两个品种；石头扁桃根、茎、叶片中Na/K比值高于其它两个品种，桃扁桃中Na/K比值最低。

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

结果：轻度牵拉组牵拉侧前角个别神经元稍肿胀，神经元及神经纤维形态基本上正常，个别白质小片状脱髓鞘样改变，神经根髓鞘和轴索轻度水肿，脱髓鞘不明显；中度牵拉组白质有脱髓鞘改变，神经纤维排列紊乱，轴索崩解、断裂；灰质神经元水肿明显加重，前角运动神经原细胞尼氏体消失，核固缩、深染，神经根髓鞘和轴索水肿，局部轻度脱髓鞘改变；重度牵拉组牵拉侧白质为不规则的大片脱髓鞘区，前角运动神经元胞体固缩、变形、核深染，神经根有髓神经纤维萎缩、数目减少，重度脱髓鞘改变。

Methods After treating 147 teeth which diagnosed as aschronic apicitis were suitable for root canal therapy,divided at random into three groups:0.5% Anerdian treatment group,FC group and dry cotton spill to seal the root canal of them.

对147颗慢性根尖炎的患牙，做常规根管处理后，随机选用0.5%安尔碘棉捻或FC棉捻消毒根管，同时与封干棉捻相对照比较。

Objective To evaluate and compare the efficacy of Periocur or formocresol as intracanal medicament in root canal therapy of chronic teeth apicitis.Methods 256 cases with chronic apicitis were divided randomly into the observational group （use Periocur as intracanal medicament） and the contol group （use formocresol as intracanal medicament）,and investigated the clinical effect after one week.

目的 观察Periocur消炎液用于根管消毒的临床疗效方法选择256例慢性根尖周炎病例，随机分成观察组（Periocur消炎液组）130例、对照组126例，观察根管封药1周后的临床疗效。
