But after about a month to restore the root system, the leaves of nitrogen, phosphorus and potassium contents in treatment 5, 6, 7, 8, 2 gradually higher than the control. This is because the absorption of fertilizer during this period shown to promote on the elements, and with the passage of time the processing elements continue to be reduced to a leaf until the latter part of the growing season is also higher than the control.3.The pH value in rhizosphere soil of treatments poplar plantation were lower than that in non-rhizosphere soil, but the content of organic,available nitrogen, phosphorus, potassium, utility cuprum and utility zincum were all higher than those in non-rhizosphere soil.

但是经过大约一个月的根系恢复，处理5、处理6、处理7、处理8、处理2叶片中的N、P、K逐渐高于对照，这是因为施肥对元素的吸收在这一期间开始表现出了促进作用，并且随着时间的推移各处理中元素含量持续降低至落叶，直至后期的生长季节也高于对照。3、各处理的杨树林地根际土壤pH值均低于非根际土壤，而有机质、碱解氮、速效磷、速效钾、有效铜和有效锌的含量均高于非根际土壤，与其它处理相比，80cm两侧断根施肥处理的根际土和非根际土壤速效养分含量最高，差异达显著水平。

Soaking seed of rice and wheat with zymolytic liquid of Trichoderma harziaiarum, Trichoderma DWC and Trichoderma viride, comparing with germinate ratio, germinate force, root length, bud length and ratio of root to bud, the results show that 50 times dilute zymolytic liquid of Trichoderma harziaiarum has a relatively notable promote role for germinate of seed .The effect of Trichoderma viride to germinate of seed is not evidence. Trichoderma DWC for seed sprout has certain inhibition.

据此，采用哈茨木霉作为出发菌株，通过离子束诱变，从大菌落株中筛选出促进生长的高产突变株——h-13菌株，通过对用该菌株发酵液处理后的水稻及小麦的种子的各项生理生化指标的测定，发现该菌株比其它菌株更能促进水稻和小麦的活力和发芽率，三天时小麦的总根长为3.03cm，比对照的1.42cm的两倍还多，并且能够明显提高种子发芽后的淀粉酶和蛋白酶的活力，其活力都是对照的两倍左右。

A research of the cultivation treatments of the commonly used compost fermentations on Volvariella Volvacea production was made in this paper by comparison with the cultivation of raw ingredients. They are zymotechnics of water-logged compost, twice regular zymotechnics and simple twice zymotechnics. The result shows that the cultivation effects of above three are better than that of the cultivation of raw ingredients, among which the simple twice zymotechnics is the best.

研究草菇生产中常用的培养基发酵方法，以生料栽培为对照，采用自然堆沤发酵法、常规二次发酵法和简易二次发酵法对草菇栽培的影响，调查结果表明：自然堆沤发酵法、常规二次发酵法和简易二次发酵法的栽培效果都要优于对照，其中，效果最好的是简易二次发酵法。

Methods Polymerise chain reaction and restriction fragment length polymorphism were used to analyze the polymorphisms of MTHFR genes C6677T and A1298C in 56 patients of colorectal cancer and 143 age-and-sex-matched control subjects.

方法以聚合酶链反应和限制性片段长度多态方法，对56例直肠癌患者和143例正常人对照的MTHFR基因C677T和A1298C基因型进行检测分析其对直肠癌风险的相关性。结果在正常对照组中，MTHFRC677TCC、CT、TT基因型频率分别为62·90%、35·08%和2·12%，而在直肠癌病人中分别为58·93%、26·77%和14·26%。A1298C与A1298C基因型在病例和对照中的分布差异无显著性意义。

After purification, PCR products of 768 clones were printed on silanized glass slides automatically using arraying system.

该方法通过将连有不同接头的两种待检样品cDNA分别与过量的对照样品cDNA进行杂交后，合并继续进行第二轮杂交，并且在杂交后利用对应于接头的特异性引物进行两轮抑制性PCR，扩增的产物通常便是同对照样品相比待检样品中差异表达的基因。

Under the treatments of ETP, the plant height and diameter, and length between adjacent double burls in the green bud stage were decreased and the effects were strengtheded along with the content of ETP increasing. The treatment of 50 mgL^(-1) postponed the time of green bud appearing 14 days and the florescence 9 days, respectively; as far as the treatments of 100 mgL^(-1) and 200 mgL^(-1) ETP were concerned, no green bud and flower appeared.

ETP处理下绿蕾中期的株高、株径和节间长度均比对照降低，且表现出随处理浓度增加效果逐渐增强的趋势。50mgL^(-1) ETP处理下绿蕾出现时间和始花时间分别比对照推迟了14天和9天；100和200mgL^(-1) ETP处理则不能正常形成绿蕾和开花。

The results are as followings: the CHA SQ-1 has the best effect of male sterility among three kinds Chemical Hybridization Agent, and has the ability to increase 1000 kernel weight. The CHA GENESIS, especially BAU9403 reduces the 1000 kernel weight. The SQ-1 and GENESIS have no significant differences with CK on the traits of geminating potential, germinating rate and volume weight, but BAU9403 has significant differences with CK. SQ-1 is a promising CHA in this experiment. It will be used in commercial seed production instead of GENESIS.
