This paper reviewed microsclerotia or spores in soil are stimulated to germinate by host root exudates, hyphae colonizes on the surface of root, pathogens penetrate epidermis and develop in cortex, expand on stem and leaf, and symptom development, shows that host plant develops various barriers to restrain this fungus invasion.

本文系统探讨了土壤中微菌核或孢子受寄主根系分泌物的刺激，开始萌发、产生的菌丝在寄主根表面定殖、穿过表皮、在皮层中发生及在寄主体内扩展和症状形成等黄萎病菌侵染棉花的过程，阐述了寄主植物形成多级防御反应阻击病原菌的入侵。

Recent advances in pelleting include "high-temperature, short-time" and "expansion" conditioning. The pressure and heat from the steam and friction in the expander increases starch gelatinization, denatures proteins, deactivates some antinutritional factors and destroys pathogenic and spoilage microorganisms. These advances have improved pellet production efficiency and pellet quality, which is usually measured by the pellet durability index.

制粒上新近的进步包括调质上的&高温－短时&、&膨化&，来自蒸汽的压力和热量以及膨化机的磨擦能增加淀粉糊化使蛋白质变性、使一些抗营养因子失活、杀死病原菌及微生物，这些进展已经改进了颗粒饲料生产率和颗粒质量，颗粒质量是以颗粒的耐久性系数来衡量的。

The application of MAS in rice bacterial blight resistance and rice blast resistance breeding programs showed it is efficient in selecting individuals containing resistance genes from a crossing population, reducing the scale of subsequent experiment, and breeding variety with pyramided genes.

以抗白叶枯病基因及抗稻热病基因为例，利用分子标志辅助选拔进行杂交后裔族群的筛选，能有效地自杂交后裔族群中筛选出具有抗病基因的个体，并可缩小病原菌接种的试验规模，快速地育成堆叠抗病基因的品系。

Beneficial bacteria, it is with the characteristic of ammonification, nitrification, denitrification, desulfidation and dephosphorylation, etc., its growth is very quickly, it has the good efficiency for degrading water quality factor, it can well reduce ammonia and nitrogen, degrade nitrite, increase the dissolved oxygen in water, activate water quality, rich water, purify water, adjust water color, increase the transparency of water, restrain the reproduction of pathogen, prevent diseases of fish, by using this product for long term, can restore the water-ecological balance destroyed by slathering disinfector, antibiotics, form the advantage community, improve the water quality quickly, keep the good water ecological balance, decrease the disk of breeding, increase the benefit of breeding.
