夏季

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。

Spring, the waters clear, Enpa Hao Sen, reed green, a vitality; summer, Lin Ling, pampas grass swaying in the wind, full bloom lotus lake, the lake little white sail, makes summer Italian Dunxiao; fall, Baiyangdian days Gao Qi Shuang pleasant weather, fish, diving face, Xie Fei wei shiang, fish fleet team, the busy fishing; winter, the snow-covered, ice Oyodo with one of Northland scenery, a variety of ice-bed shuttle, as the swallows fly in the air, is a great natural ice rink can be either a clear run.

春季，水域清澈，烟波浩森，芦苇翠绿，一片勃勃生机；夏季，莲菱蒲苇随风摇曳，满淀荷花盛开，湖内白帆点点，使人暑意顿消；秋季，白洋淀天高气爽，气候宜人，鱼跳水面，蟹肥味香、鱼船队队、捕捞繁忙；冬季，白雪皑皑，冰封大淀，一派北国风光，各种冰床穿梭往来，如同燕子在空中飞翔，是一个巨大的天然滑冰场，可任自由驰骋。

There are some isoforms of PAPs showing inhibitory ability to virus infection in various organs and at different stages of development. Three different species of the protein can be isolated from leaves of pokeweed. Proteins were precipitated with 50-80% ammonium sulfate from leaves in spring, summer and autumn respectively. Proteins were purified on SP cation-exchange then on MQ anion-exchange and finally on MS cation-exchange or on MQ anion-exchange. We found that some new pokeweed antiviral proteins separated from these leaves were different from PAP, PAPII and PAPIII.

对美洲商陆春季、夏季、秋季采集的叶片，用50-80％饱和度硫酸铵沉淀出来的蛋白样品，经过SP阳离子柱后，上MQ阴离子柱，然后把活性蛋白峰再上MS阳离子柱或MQ阴离子柱分离，从春季叶片中分离出四个不同的抗病毒蛋白峰；从夏季叶片中分离出二个不同的抗病毒蛋白峰，这两个蛋白峰与春季叶片中分离出的活性蛋白峰都能重叠上；但从秋季叶片中只分离出来一个抗病毒蛋白峰，它和春季、夏季叶片中分离出的活性蛋白峰都重叠不上。

Then the dominant species of each season was identified and the contribution of the abundance of these dominant species to total abundance was analyzed. The results indicate an obvious succession of dominant species. Centropages dorsispinatus, Acartia pacifica ca and Sagitta enflata were the primary dominant species in summer, however, Paracalanus aculeatus, Acartia pacifica and Paracalanus crassirostris were the major dominant species in autumn.

结果表明，两个季节优势种具有明显更替现象，夏季（6月）主要优势种为背针胸刺水蚤、太平洋纺锤水蚤和肥胖箭虫；秋季（9月）主要优势种是针刺拟哲水蚤、太平洋纺锤水蚤和强额拟哲水蚤。
