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。

From analysis it could be seen that intercropping aromatic plants in sand soil in pear orchard had good regulatory effects on the soil microbial quantity, the ratio of the soil fungi, bacteria and actinomyees in soil microbial community and the soil available nutrients, among which, intercropping Ocimum basilicum L on the soil microbial quantity and content of the soil nutrients was better than other treatments.

间作芳香植物对于沙地梨园土壤微生物数量及其群落中真菌、细菌和放线菌的比例与土壤中有效态养分含量具有良好的调节作用,其中柠檬罗勒对提高梨园土壤微生物数量、土壤养分含量的综合效果最佳。

The results indicate that the economic, ecological, social and comprehensive benefits of hedgerow intercropping are superior to that of traditional sloping cultivation. The comprehensive benefit of hedgerow intercropping of Leucaena leucocephala is better than that of Tephrosia candida. The results also indicate that application of superphosphate fertilizer for intercropping system improves crop yield and comprehensive benefits.

评价结果表明,植物篱种植模式的生态效益、经济效益、社会效益及综合效益均大于顺坡耕作模式,种植新银合欢植物篱比种植山毛豆植物篱的综合效益高;在种植相同植物篱树种的前提下,施磷肥比不施磷肥的效果好。

Through the comparative analysis of the arthropod community between intercropping system and the three control systems~the weeding jujube yard system, not weeding jujube yard system and the system of farmland, it is showed that the intercropping system have a more richer neutral arthropod groups. Compared to Weeding jujube yard system and system of farmland the intercropping system have more advantages in natural enemies groups and more disadvantaged phytophagy groups. And the intercropping system can rebuild the arthropod community more faster than the other systems after the system was seriously disturbed, so it is than compared to other three systems the intercropping system have more proper structure and more stronger regulation ability and also more stronger ability to control pest.

对枣粮间作系统和三种对照系统,即除草枣园系统、未除草枣园系统和农田系统的节肢动物群落进行对比分析发现枣粮间作系统具有更为丰富的中性节肢动物类群,比起除草枣园系统和农田系统有更优势的天敌类群和更劣势的植食性类群,且在遭受生境的巨大变化后新生境重新形成时枣粮间作系统的各亚系统能更迅速的形成节肢动物群落和各种功能类群,说明枣粮间作系统比三种对照系统的节肢动物群落有着更合理的结构、更强的调控能力和更强的控害能力。

Our work reported here are aiming at improving nitrogen and water use efficiency in wheat/maize, faba bean/maize, pea/maize and soybean/maize intercropping through field experiment.The main results obtained were as the following:(1) Land equivalent ratio was greater than 1.0 for faba bean (Viciafaba L.)/maize (Zea mays L.) intercropping regardless of nitrogen fertilizer application or not. Based on grain yields production, LER of pea (Pisum sativum L.)/maize intercropping was over 1.0 in spite of nitrogen fertilizer application, while LER was higher than 1.0 only when nitrogen fertilizer was applied based on biomass production. However, LER in soybean (Glycine max L.)/maize intercropping was smaller than 1.0 both nitrogen applicationa and no nitrogen application. In wheat Triticum aestivum L.

本文通过田间试验,对小麦/玉米、蚕豆/玉米、大豆/玉米和豌豆/玉米间作种植下作物对氮素和水分利用的影响进行了系统比较,获得的主要结果如下:(1)蚕豆/玉米间作的土地当量比都大于1;豌豆/玉米间作以籽粒产量为基础的LER无论施氮还是不施氮都大于1,而以生物学产量为基础的LER只有施用氮肥时才大于1;大豆/玉米间作无论施氮还是不施氮LER均小于1。

Nitrogen also increased the rate of wheat yield of intercropping single for Gao Yu, reflecting the presence of wheat intercropped with nitrogen from the beans to the transfer of wheat, resulting in intercropping conditions decreased the sensitivity of wheat to nitrogen fertilizer.

同时施氮增加小麦产量的幅度以单作高于间作,这反映了在小麦蚕豆间作体系中存在着氮素由蚕豆向小麦的转移,导致在间作条件下小麦对氮肥的敏感性下降。

Result With young elm forest-pumpkin strip intercropping, since the branch tendril covered the gap between pumpkin planting-ditches and elm forest land, the soil moisture was remarkably increased. And the water use efficiency under intercropping increased by 23.7%-163.3% compared with the sole cropping. Elm-pumpkin strip intercropping changed the sequential succession trend of the grasses growing in the gap of the pumpkin planting-ditch, annual grasses became the dominant vegetation, and the feeding nutrient matter content and yield of the annual grasses increased significantly.

榆树幼林与南瓜间作后,瓜蔓覆盖地面,显著提高了南瓜行间和榆树林地的土壤水分含量,林-瓜间作地水分的利用效率较单作提高了23.7%~163.3%;间作改变了南瓜行间杂草群落自然演替的方向,一年生杂草成为优势物种,其饲用营养物质的含量和产量较林带间杂草显著提高。

The daily mean air temperature of 20 cm height,daily change of air temperature and daily maximum temperature in the areas without intercropping were higher or larger than those with intercropping of rye grass;the air humidity in the areas with intercropping of rye grass was higher than that without intercropping.

结果表明,在热状况下,自然裸露区域桃园的空气温度日较差、日极端最高温度和20 cm高度处的空气平均温度均高于黑麦草套种区,空气湿度则黑麦草套种区明显大于自然裸露区。
