随植株氮水平提高，叶绿素总含量提高，但叶绿素b的提高速度快于叶绿素a；当植株叶片含氮率在2％以下时，随植株氮水平提高，水稻叶片淀粉积累不仅没有减少，相反叶片中的糖含量和下层叶的淀粉含量还有显著提高；当植株叶片含氮率在2.0％到2.8％的适宜水平时，叶片SPS酶活力和可溶性糖含量最高，有利于叶片中积累物质向籽粒转运。

The result indicates that with organic fertilizer and inorganic nitrogen fertilizer can obviously increase the leaf dimension coefficient, enhance the content of chlorophyll and soluble protein, improve the SOD activity of flag leaf, depress the content of MDA, postpone the speed of decrepitude of flag leaf,; The status with high content of chlorophyll and leaf dimension coefficient lasts longer with organic fertilizer than with inorganic nitrogen fertilizer and the flag leaf have longer functioning time; the combination of inorganic nitrogen fertilizer and organic fertilizer can substantially postpone the speed of decrepitude of winter wheat.

在国内持续时间最长的肥料长期定位（28年）试验条件下，研究了肥料持续施用下冬小麦花后叶面积系数等生理指标的变化，结果表明施用有机肥、氮肥，可明显增大小麦的叶面积系数，增加叶绿素含量和可溶性蛋白含量，提高旗叶的SOD活性，降低丙二醛的含量，延缓旗叶的衰老；施用有机肥较施用氮肥，叶绿素含量及叶面积系数持续高值时间长，旗叶有更长的功能期；长期氮肥与有机肥配施能显著延缓小麦衰老。

That is the comprehensive evaluation about the grasses. With SAS Microsoft, Q-type system cluster is done according to the weight of the indices coming from the hierarchy analysis and the grades of the indices. The result is that all the grasses are divided into six types (r0.7) and its almost consistent with the result of comprehensive evaluation but there is slightly difference about red clover, white clover and cocksfoot.

在利用层次分析法得出权重和确定指标分级的基础上，运用SAS统计软件进行数据处理，采用类平均法进行Q型系统聚类，当λ=0.7时，聚类结果与综合性状评定划分的类型基本一致，只在白三叶、红三叶和鸭茅分属类型上有差异。

The present study investigatated the effect on the diversification of weed community, including weed abundance, dominance, evenness, biomass, and mean height after mulching straw and intercropping white clover in the tea plantation from 2005 to 2006. The results were as follows: 16 families and 31 species were found in total. In April, the dominant species characterized with slow growth, lower biomass, and less than 30 cm height; in July those who grow faster with higher biomass and height became dominant; In September, these malignant communities reduced, while the oxalis and diffusa characterized with lower biomass and low height gradually increased. In the three seasons, the weed abundance, community diversity and evenness increased, and the dominance, the biomass and average height of weeds remarkably reduced after intercropping white clover and muching straw.

结果表明：茶园共有杂草16科31属31种，春季（4月）以生长速度较慢、生物量小、株高在30 cm以下的杂草为主，夏季（7月）以生长快、植株高和生物量大恶性杂草为主，秋季（9月）恶性杂草开始减少，酢浆草、白花蛇舌草等生物量小、株高矮的杂草逐渐增多；稻草覆盖处理茶园春、夏和秋季3个观测时期杂草物种丰富度、多样性、均匀度等指数均高于清耕对照，优势集中性指数低于清耕对照；间种白三叶草处理春、夏和秋季3个观测时期杂草总数量和生物量均显著低于清耕对照，夏、秋季杂草平均株高显著低于清耕对照；稻草覆盖和间种白三叶草处理春季茶芽重和产量显著高于清耕对照，鲜叶中游离氨基酸含量高于清耕对照，茶叶感官评审得分高于清耕对照处理。

For some kinds of vegetables and pasturages, the contents of some heavy metals surpass the relevant quality standards, so when some crops were planted on the substrates, the uneatable species should be selected preferably and if some kinds of vegetables and pasturages must be adopted, the output could not be provided to mankind and also not be used in farming, in order to avoid harming peoples'health.5 The expediency evaluation model of pioneer plant on substrates was established and some plants were studied. The results show that the expediency evaluation of pioneer plants were respectively that clover was expedient to substrate 1, juniper, cotton and fescue were expedient to substrate 2 and juniper, annual bluegrass, fescue, cotton and clover were expedient to substrate 3.6 Some indexes to evaluate the capability of the phytoremediation on heavy metals and the comprehension about hyperaccumulator were put forward.
