滇中高原地区地膜覆盖种植花生的增产与增温效应分析

在滇中海拔1870米地区地膜覆盖种植花生试验表明:与无膜对照区比较,地膜区(A)增产124％,柴灰加盖地膜区(B)增产145％,其中B比A区又增产约10％。文中讨论了盖膜增温效应,云南省花生产量与气候的关系,以及盖膜种植在云南南、中、北部推广应用中应注意的问题。

AN ANALYSIS FOR THE EFFECT OF INCREASING PEANUT FIELD AND TEMPERATURE COVERED WITH PLASTIC FILM IN THE PLATEAU REGION OF CENTRAL YUNNAN

The experiment in the planting peanut covered with plastic film comparing with that no the film in the plateau region of central yunnan indicated that the Peanut field of covering with the film (A) and with both the ashes and the film (B) increased by 124% and 145%,respectively, and the field in the area B increased by about 10% more than that in the area A.This Paper also discussed the effect of increasing temperature of upper soil covered with the film,the relationship between the peanut field and the climate in Yunnan province, and the problems which should be paid attention to when the technique is popularized and applied in the south, central and north parts of Yunnan.
