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 )
在本試驗條件下，小麥與油菜或鷹嘴豆混作能顯著改善小麥的生長及錳營養，其地上部干重及吸錳量均以根系不分隔處理顯著高於根系完全分隔處理；油菜和鷹嘴豆的生長受小麥抑制，均表現為不分隔處理的地上部干重及吸錳量顯著低於完全分隔。 -
It was found : 1 ) the film restrained evaporation surface intensity and had obvious function of rising and keeping moisture, 2 ) the drip irrigation could supply water according to growing requirement and augment of water conflux intensity around crop root, it also had strongly controllable operation and wasted fewer water
覆膜抑制了土壤表面的蒸發面匯，具有明顯的提墑保墑作用，滴灌能隨時根據作物生長需要及作物根系匯流強度的增大而補充匯流源，可控性很強，水的浪費率很低。 -
This paper, briefing on the controlled root - split alternate irrigation, a new idea of saving and regulating on - farm water use whereby crop water requ i rement can be satisfied while controlling transpiration, gives out its definitio n, traces the historical development of studies in relation to the adoption of t he techniques concerned at home and abroad, summarizes the main research finding s in the technical aspects of the controlled root - split alternate irrigation in the past two years and makes an analysis on some of the problems that may exist in the implementation of this technique
