- Abstract:
- A field experiment was conducted to study the influences of black plastic film, blue plastic film, red plastic film and transparent plastic film mulching on the corn in Oasis irrigated area in order to explore the main agronomic traits of corn through the environmental correlation analysis. The economic output performed that the black film production reduced by 9.22%, blue film yield increased by 9.23%, and red film yield also increased by 2.29% relative to the transparent plastic film. The result of corn yield per plant by black film is the highest. With respect to the major agronomic traits, the result of various agronomic traits of corn by blue color film showed the highest value in terms of stem thickness, emergence rate, spike length and grains per ear. And the black film mulch showed the highest 1000-grain weight, the lowest emergence rate and the biggest spike height. The result indicated the correlation coefficient of environment for the traits to yield per plant was not significant, indicating the less effect of environmental factors on plant productivity and these seven traits. The environment correlation coefficients of each trait on grain yield per plant were showed the sequence: 1000-grain weight > ear rows > seed production percentage > grains per row > spike thickness > grains per ear > spike length.
