Phytogeography which study flora geography and vegetation geography research the relation between the plant distribution and space and time. It has great meaning for studying plant distribution , flora evolve , protection and utilization of plant resources, vegetation evolve etc..

植物地理学研究植物区系地理和植被地理即植物分布与空间及时间的关系，对于研究植物的分布、区系演化、植物资源保护和利用、植被演替等均有重大的意义。

The pipal tree was regarded as sacred both in Harappa and Elam (It may be due to the fact that this is the only plant in the plant kingdom which releases more amount of oxygen day and night, than any other plant).

菩提树被认为是Harappa和埃兰神的两面（由于这个事实，它仅仅是比任何其它植物日夜释放更多的氧气的植物王国的植物）。

By learning the course, students those who do not major in plant protection can understand the basic conception of plant protection science, the occurrence law, prediction methods, the prevention technology and strategies of agricultural pests, and the basic theories and elementary knowledge of the integratedpest management and the extension of plant protection technology.

课程简介：本课程的教学目的是使农科非植物保护专业本科生了解植物保护学的基本概念、植物保护涉及到的各类有害生物及其危害发生规律、预测方法、防治技术与策略，以及主要农作物有害生物的综合治理和植物保护技术的推广应用等方面的基本理论和基本知识。

Field trials on the effect of three levels (1.0, 1.5 and 2.0 kg/plant/year in plant cropping, and 0.76, 1.06 and 1.36 kg/plant/year in ratoon cropping) of compound fertilizer Tai-Fei No.4 on the vegetative growth, yield and post-harvest quality attributes of TC1-229, a semi-dwarf, fusarial wilt-resistant banana clone, were conducted on a soil of silt loam with a pH of 8.0 and 2% of organic matter for two consecutive years.

在有机质含量约百分之二的坋质壤土定植中矮性抗黄叶病品系TC1-229组织培养苗蕉株，每年每株施用台肥四号复合肥料1.0，1.5或2.0公斤，抽穗期叶片之矿物营养组成均在正常范围内，惟磷和镁含量随肥料施用量减少，处理间差异达显著水准(P=0.05)。

A new switching scheme to the gain of variable structure control signals is proposed. The following important open problems in standard VS-MRAC and MRAC are solved by using the scheme: 1 . a prespecified transient and steady-state performance index for tracking error can be achieved without requiring any information about the plant high frequency gain sign when relative degree of modelled part of plant is one, and 2 . it is shown that as long as the performance indexes are guaranteed for the auxiliary errors, each of which in dynamics is a sub-system with relative degree one, the tracing error will converge to a small residual set in a prespecified transient time when relative degree of modelled part of plant is greater than one.

提出了一种控制增益可切换的变结构自适应律，解决了如下变结构模型参考自适应控制（包括基于调参律的模型参考自适应控制）理论研究中长期没有解决的问题：当对象建模部分相对阶为1、高频增益符号未知且存在非线性输入扰动和未建模动态等情况下，系统跟踪误差可满足预先给定的动态和稳态性能指标；当对象建模部分相对阶大于1且存在非线性输入扰动和未建模动态时，可保证系统跟踪误差在预先给定的过渡过程时间内收敛到一个残差集中； 5。

Aphids belong to Diptera insect pests; they damage plants directly by sucking juice of phloem, and indirectly by spreading plant disease. The plant lectins are proteins that bind reviviscence to specific mono- or oligosaccharides; therefore they have potential in plant genetic engineering.

本研究还克隆了植物凝集素基因，以解决棉花蚜虫的危害问题，蚜虫属同翅目昆虫，通过吸取植物韧皮部的汁液造成直接危害，又通过传播植物病害对植物造成间接危害，植物凝集素是一类具有特异糖结合活性的蛋白，在植物基因工程中具有较大的应用潜力。

Influence of plant species coexisting on AMF colonization in root system under field conditions The field experiment showed that the influence of species coexisting community on the AMF colonization in these plant root system significantly depended upon the plant species character.

泡囊数主要说明AMF在宿主根系的定殖程度，泡囊数表现出与菌根侵染率相似的变化规律，也是各物种共存组合与单个物种相比变化不大，但泡囊数在铅污染土壤中明显增加，这可能是铅污染刺激了这些草的菌根膨大。
