结果表明，多数间作作物对玉米生物量没有明显影响，只有扁豆对玉米生长有较明显的抑制作用，使玉米生物量降至对照的67.8%。

Nitrate-N content in 0~60cm soil profile with intercropped faba bean and pea are lower than the monocrops under zero N application and 225kghm^(-2) N application; while that with soybean lower than the monocrop at zero N application, but higher at 225kghm^(-2) N application.

玉米收获期，不施氮条件下3种豆科作物间作0~60cm土壤硝态氮含量均低于单作；225kghm^(-2)氮水平下，蚕豆、豌豆间作0~60cm土壤硝态氮含量低于单作，而间作大豆0~100cm土壤硝态氮含量高于单作。

The study indicated that Choerospondias axillaries cropped with peanut wasn't optimum agroforestry model and it couldn't be extended blindly in subtropical China, that N〓-fixing shrub should be chosen to intercropped in farmland rather than tree, and that shade tolerance plant should be chosen to intercropped in orchard garden or man-made forest rather than photophilous plant in alley cropping system.

总之，花生南酸枣间作不是低丘红壤地区优化农林间作模式，不适宜盲目发展。在红壤农田系统中实行农林间作应优先选择固氮灌木，而非高大的乔木；在果园或人工林系统中实行农林间作应优先选择耐荫植物，而非花生等喜光作物。

So it is held that inoculation of bean crops with appropriate rhizobium is an approach to further promoting the merits of N nutrition of the legumious/gramineous intercropping system.

因此，本研究认为豆科作物接种合适的根瘤菌，是进一步提高豆科/禾本科作物间作系统氮营养间作优势的又一重要途径。

Cultivation of legumes, green manures or deep-rooting plants during the rotation or as interplanting in perennial crops.

在轮作中种植豆科作物、绿肥或者是深耕作物，或在多年生作物中间作这类作物。

Our work reported here are aiming at improving nitrogen and water use efficiency in wheat/maize, faba bean/maize, pea/maize and soybean/maize intercropping through field experiment.The main results obtained were as the following:(1) Land equivalent ratio was greater than 1.0 for faba bean (Viciafaba L.)/maize (Zea mays L.) intercropping regardless of nitrogen fertilizer application or not. Based on grain yields production, LER of pea (Pisum sativum L.)/maize intercropping was over 1.0 in spite of nitrogen fertilizer application, while LER was higher than 1.0 only when nitrogen fertilizer was applied based on biomass production. However, LER in soybean (Glycine max L.)/maize intercropping was smaller than 1.0 both nitrogen applicationa and no nitrogen application. In wheat Triticum aestivum L.

本文通过田间试验，对小麦／玉米、蚕豆／玉米、大豆／玉米和豌豆／玉米间作种植下作物对氮素和水分利用的影响进行了系统比较，获得的主要结果如下：(1)蚕豆／玉米间作的土地当量比都大于1；豌豆／玉米间作以籽粒产量为基础的LER无论施氮还是不施氮都大于1，而以生物学产量为基础的LER只有施用氮肥时才大于1；大豆／玉米间作无论施氮还是不施氮LER均小于1。

In this paper, the author took the intercropped fields of forest and cereal crops as analytic target, which is located in Han Jiang County of Jiangsu Province.

本文以江苏省邗江县池杉、稻麦间作田为基本分析对象，讨论了池杉对于林下作物的遮荫效果，为合理安排间作密度，充分利用光热资源，提供了数量化的依据。

The changes of nitrogen content, free amino acid, C/N ratio and chlorophyll content of wheat in wheat-faba bean intercropping system were studied by pot experiment with 3 N levels 0, 75 and 150 mg Nkg^(-1 soil. The results showed that leaf nitrogen content of intercropped wheat was higher than that of monocultured wheat at 3N level at tilling and booting stages, but was lower at heading stages.

为了解小麦蚕豆间作系统中小麦氮同化物的变化特征，探讨小麦蚕豆间作提高作物抗病性的可能机制，通过盆栽试验的方法，研究了小麦植株全氮含量、叶片游离氨基酸、叶片C/N比和叶绿素含量的动态变化及供氮水平对其的影响。

The increased yield of the intercrops might be attributed to the improved nitrogen and phosphorus nutrition of soybean and maize under intercropping conditions.

我们的研究结果初步阐明了间作作物之间的营养互作机理，可为农业生产中间作系统的栽培管理提供理论依据。

There was an interaction between maize and intercrops in Cd uptake. Legumes absorbed smaller amount of Cd but significantly increased the Cd uptake by maize, while amaranth was in adverse. Rape had a higher level of Cd concentration in its shoot, but reduced the Cd in aboveground part of maize.

间作植物与玉米对Cd的吸收具有不同的交互作用特征，豆科作物在自身较少吸收Cd的条件下，显著提高了玉米对Cd的积累；籽粒苋在自身大量累积Cd的同时，一定程度上抑制了与其间作的玉米的Cd累积量；油菜地上部分吸收较多的Cd，但降低了玉米地上部分Cd含量。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.
