Soil microbial biomass and activities of invertase and urease all tended to decrease after pot-culture experiment, while the correlations between these biochemical properties and field ages were similar to those before this experiment, suggesting that rice cultivation without fertilization consumed part of soil microbial biomass, decreased soil enzyme activities correlated with C and N transformation, and affected soil nutrients status disadvantageously.
温室盆栽试验之后，水稻土的微生物生物量及酶活性与利用年限之间的关系规律和种植水稻之前基本一致，且整体上又趋于下降，即无施肥条件下种植水稻转化利用了土壤部分微生物生物量，并减弱了与碳氮转化相关酶的活性，对保持水稻土的营养水平造成不利影响。

In order to get the relationship between mental pollution in soil and vegetables and support green vegetable production, five kinds of common foliage vegetables(Lettuce Plant, Schizonepeta Tenuifolia Briq, Lpomoea aquelica, lettuce, Amaranthus hypochondriacus) were taken as experimental materials to study the correlation between the polluted vegetables and the soil of different concentration of Cd cultivated in greenhouse. The soil pollution threshold values to produce the green vegetables were analyzed.
为探求土壤重金属污染和蔬菜污染的相关性，为绿色蔬菜生产提供技术支持，该研究以郑州市常见的5种叶菜类蔬菜(油麦菜、荆芥、蕹菜、生菜、苋菜)为试验材料，采用温室盆栽土培试验方法研究了土壤不同浓度 Cd污染与蔬菜污染的相关性，并对绿色蔬菜生产要求的土壤污染阈限值进行了分析。

In Hubei. After screening, two strains of fungal parasites were gottenwhich had stronger. ability to parasite Meloidogyne eggs. Their parasitic ratio tothe root knot eggs was 78.04% and 70.02% in concave slides and water agar plates,72.37% and 65.65% in pots. The effective hatchings in experimental containers wereonly 5.02% and 8.32%, and there were 100% in controls.
