During studying different levels potential yield of main cropping modes, bring forward the conception of "equivalence potential yield", and this conception made potential yield of different crops comparable and transpositional. So we can analyze the main factors influencing mostly different levels potential yield of monoculture and main cropping modes for different regions.
在对种植模式生产潜力的研究过程中提出了等价生产潜力的概念,以解决不同作物间生产力的横向比较与换算问题,同时注意到单一作物与种植模式间的生产潜力影响因素,并量化分析了这些主要的影响。

We selected Streptomyces strain FXJ2.014 with high bioactivity for further analysis and found additional metabolites in fermentation extracts of cocultures of strains FXJ2.014, FXJ1.296 and AS 4.1252 respectively with B. subtilis. Quinomycin A was the main bioactive metabolite produced by the monoculture of strain FXJ2.014, while a new quinomycin-like component named FXJ2.014-HB was produced when strain FXJ2.014 was cocultured with B.
发现FXJ2.014、FXJ1.296、AS 4.1252三株菌与枯草芽孢杆菌共培养时产生其在相同条件下单培养时没有的物质,其中链霉菌FXJ2.014单培养时主要产生醌霉素A,共培养时产物中增加了醌霉素结构类似物FXJ2.014-HB。

Inwheat intercropped with soybean not only N situation could be improved butalso P situation could be.2In intercropping,the pH of soybean rhizospherewas decreased by increasing the R-Apase activity,which could decelerate thetransforming and fixing P fertilizer.3In both monoculture and intercroppingsystem,the soil pH of rhizosphere was affected by cropping system at two Plevel which only 0.1-4mm distance from the root surface,but the effect of S-Apase activity in the rhizospher soil by cropping system was less than3mm.In effect,the rhizosphere P was really available nutrient,and applyingP to rhizosphere was effective ways to reduce the P nutrient competition.4Inwheat/soybean intercropping,the peak stage of reduction ability of roots wasthe same as that of the root growth,so that the time compensation appearedin intensity of nutrient absorption.
间套作大豆、小麦、玉米根系Apase的差异又反映出大豆利用土壤磷的潜在能力最大,而玉米最小,可见禾谷类的小麦与大豆间套后不但能改善小麦的氮素营养状况还使磷素营养也得以好转。2)间套大豆根际pH值的下降,导致磷肥施入土壤后形成〓-P的比例显著提高,转化成〓-P等难溶性磷减少,说明间套的大豆能减缓肥料磷在土壤中的转化和固定,减少磷素向无效化方向转化。3)复合群体根际土壤pH值的影响一般只发生在0.1-4mm的根际微区,而土壤磷酸酶的影响供磷与否在距根表3mm以外都无多大差异,说明根际磷才是真正有效磷,根际施磷是解决磷素竞争的有效途径。4)。
