Effect of high day-time temperature on rice quality under different panicle nitrogen treatments

To determine the effects of elevated temperature during grain filling on grain quality of rice,Wuyujing 3(japonica rice) was planted in pots under elevated night temperature(ENT) and elevated daytime temperature(EDT) at the grain filling stage by using far-infrared heaters.

grown under sunlight after night low temperature were studied.

The germnation day temperature of Cymbidium hybridum,including Xing-yu , Ying-xiong , Zhi-nv , Xiang-jiao-chuan and Niu-lang ,was observed to determinte the optimal germination temperature.

Through flowerpot test and the adoption of index measurement,inspection of the differences of dominant averaging values and other methods,the researcher gives the conclusion that different day temperatures,sunlight all have marked impact on Phalaenopsis for its growth and blossom property.

The main function of plastic film is increasing temperature and humidity.

Effect of increasing temperature with hanging white film coverage was better than white film transfer coating coverage, white film transfer coating coverage was better than blue and black film transfer coating coverage, black film transfer coating coverage was better than blue film transfer coating and without coverage.

The charactrtistics of the temperature in the soil layers under the condition of the corn and cotton covered with film,the result shows there is an apparent effect on increasing temperature when the soil layers covered with film.
