A discussion on the rice - millet blended zone in the neolithic age 新石器时代粟稻混作区初探

At the same time , scientists have to deal with concerns about genetically engineered plants accidentally mixing with food crops 同时，科学们必须处理有关转基因植物和粮食作物的混作问题。

In the wheat - oat intercropping system , root barriers had no effects on shoot dry weight of wheat , and mn nutrition of wheat was not improved by the oat - wheat rotation as well 整体来看，在本试验条件下的小麦燕麦种植体系中，根系分隔方式对小麦地上部生物量的影响不明显；而且，不论是混作还是轮作，燕麦对小麦锰营养的改善作用均不显著。

Interspecific interactions can affect micronutrients uptake . thus pot experiments were conducted to investigate the effects of oat , rape and chickpea on mn nutrition of wheat in intercropping system or in oat - wheat rotation 基于以上理论，本研究采用盆栽试验探讨了在不同的种植方式下(间、混作和轮作) ，燕麦、油菜、鹰嘴豆对小麦生长及锰营养的影响。

Wheat was the dominating crop in aspects of both the growth and mn nutrients competition either in wheat - rape or in wheat - chickpea intercropping system , but the growths of rape and chickpea were suppressed by wheat . root barriers did not affect the total shoot dry weight in wheat - oat system , but the total mn uptake was lower in no barrier treatment ( mixed cropping ) than in solid barrier treatment ( mono cropping ) 在本试验条件下，小麦与油菜或鹰嘴豆混作能显著改善小麦的生长及锰营养，其地上部干重及吸锰量均以根系不分隔处理显著高于根系完全分隔处理；油菜和鹰嘴豆的生长受小麦抑制，均表现为不分隔处理的地上部干重及吸锰量显著低于完全分隔。
