The results showed that at the beginning stage of being attacked by Chinesis white pine beetle and their symbiotic blue-stain fungus, PAL, PPO, SOD activities and MDA content significantly increased in the phloem of P. armandi, and decreased with the increase of the number of D. armandi and the attacking on the xylem and phloem of P. armandi from blue-stain fungus, then reached the minimum level in withering stage of P. armandi. But the contents of nutrition materials in the phloem, such as water, protein, glucide, fat, amylum and so on, declined with the infestation of D. armandi and symbiotic fungus. In summary, the resistance of physiology and biochemistry in the phloem of P.

结果表明，在华山松大小蠹和共生蓝变真菌危害初期，华山松韧皮部内的苯丙氨酸解氨酶、多酚氧化酶、超氧化物歧化酶活性均显著提高，丙二醛含量明显增加；但随着华山松大小蠹种群数量的增加和蓝变真菌对华山松韧皮部和木质部组织危害的加剧，韧皮部组织内的PAL、PPO和SOD活性逐渐降低，在枯立木阶段降至最低；与此同时，华山松韧皮部内的水分及蛋白质、糖类、粗脂肪、淀粉等营养物质含量，则随华山松大小蠹和共生蓝变真菌危害的加剧而不断减少。

Mycorrhiza is a mutualistic symbiosis between plants and fungi, and ectomycorrhiza is an important type of mycorrhiza.

Mycorrhiza is a mutualistic symbiosis between plants and fungi, and ectomycorrhiza is an important type of mycorrhiza.

菌根是一种植物营养根与土壤真菌形成的共生体，在自然界中分布广泛。外生菌根真菌是菌根真菌的重要类群，其宿主植物约占陆地植物总数的3%左右。

There were a great deal of kinds of the grass with high quality and quantity fed to fish To determine the best symbiosis ecosystem of fish and grass on a closed system circulated yearly, several cold and warm grass was selected to analyse the adaptability and nutrition absorbed. It indicted that Lolium multiform Lam. and lemarthria compressa were the best option due to high adaptability of wetness, high coarse protein, fat and fibre and so on in the leaf, high biomass, high bio-filtration effect of N and P, adaption to the low or high temperature, resist to the plant diseases and insect pests, and the food of fish whose forage was grass.

鱼用优质高产牧草的种类繁多，为确定最佳的鱼草共生周年循环系统，本文选择几种冷季牧草和暖季牧草进行生长适应性与营养吸收研究，分析表明，多花黑麦草和扁穗牛鞭草是最佳的冷季牧草和暖季牧草，它们耐水性强，叶片中所含的粗蛋白、粗脂肪、粗纤维等化学成分高，植株的生物量也高，生物过滤养殖废水中的氮和磷效果好，而且可以适应外界环境的低温或高温，抵抗病虫侵害，同时为草食性鱼类喜欢食用。

In this paper five strains of Arbuscular mycorrhizal fungi inoculums were used in organic soil before tomato seed sowing.

丛枝菌根是生活在陆生植物根际的有益共生微生物，大多数作物、蔬菜、果树和观赏植物均可形成丛枝菌根共生体〔1，2〕，由于有机栽培下营养物质转化吸收不如化肥效果迅速，不能完全满足蔬菜生长需求，因此产量一般较低。
