But systematic research concerning continuous mono-cropping grafted cucumber obstacle isn't reported. This paper systematically studied the effect of continuous cropping soil on grafted cucumber in aspect of its growth, yield and edaphon in pot experiments. Further more, root exudates of squash and grafted cucumber were collected by solution cultivate and adsorption of XAD-4 resins, and bioassay of the root exudates was did with cucumber and squash as receptors, studied allelopathy of grafted cucumber and squash root exudates on cucumber and squash , physiobiochemistry as well as.
本项研究采用盆栽试验以不同连作年限的土壤为基质比较系统地研究了连作年限对嫁接黄瓜的生长、产量和土壤微生物的影响;采用水培和XAD-4树脂吸附法分别收集嫁接黄瓜和砧木南瓜的根系分泌物并以黄瓜、南瓜为受体进行生物活性测定,并对嫁接黄瓜及其砧木南瓜根系分泌物化感作用的生理机制进行了初步探索。

Microphylla plantations are obvious, such effects and the contents of soil organic matter, N, P and K are gradually increased with the growth of C. microphylla plantations. Moreover, the activities of phosphomonoesterase, saccharase, protease, urease, dehydrogenase, polyphenol oxidase and nitrate reductase and the contents of edaphon C, N and P are significantly increased at soil depth of 0~30 cm, especially at soil depth of 0~10 cm.
随着小叶锦鸡儿固沙群落发育时间的增长,其综合防风性能提高,土壤有机质、N,P,K含量和生物活性逐渐得到改善。0~30 cm土层中磷酸单酯酶、蛋白酶、脲酶、蔗糖酶、硝酸还原酶、多酚氧化酶、脱氢酶的活性和土壤微生物生物量C,N和P含量均大幅度提高,其中0~10 cm土层增幅最大。

Wood Vinegar is a natural material that is distilled from wood. It is compose of organic acid and hydroxybenzene , Various dosage of wood vinegars, pyrolignerous acid and guaiacol were mixed into organic manure firstly in this experiment, and then, the above said organic manure are separately added into soil. Under the analysis of the amount of the edaphon, adding 10g wood vinegar to 1kg organic manure and 30kg soil can much active the edaphon effectively in a short term and make a maximum rising extent of edaphon numbers.
木醋液是从多年生柞木中经过高温蒸馏出来的纯天然物质,其主要成分是有机酸和酚类物质,为了明确木醋液和主要成分对土壤微生物的作用,将加入不同剂量的木醋液、愈创木酚、醋酸的有机肥施入土壤,观察土壤中微生物数量的变化,结果表明:在1kg有机肥中加入10g木醋液,施入30kg土壤中,土壤微生物数量增加幅度最大,土壤微生物10天内被有效地激活;同时,当在1kg有机肥中木醋液的添加量高达50g时,对土壤微生物有一定的抑制作用。

At the same time, a continuous restraint on the edaphon, including those existing in the tested roots will happen when 50g wood vinegar are added into 1kg organic manure and 30kg soil.However, the influence of pyrolignerous acid and guaiacol were not same with wood vinegars. The reason that wood vinegars can much active the edaphon effectively, is not only the pyrolignerous acid or guaiacol reacted.
此外,通过采用木醋液中的两种主要成份醋酸与愈创木酚对比试验,表明其对土壤微生物数量的影响与木醋液不相关,木醋液能起到增加土壤微生物数量的作用,虽然有可能是其他物质在起主导作用,但更有可能的是多种物质的综合作用。
