Effects of Macromolecule Water Absorbent Resin on Physiological Characteristics and Water Use of Winter Wheat
並列摘要
Macromolecule water absorbent resin has functions such as water absorption, soil moisture conservation and soil improvement, as well as other functions. In this study, in order to explore the effect of macromolecule water absorbent resin on wheat roots and to determine the physiological characteristics of the leaves during different growth stages, a field experiment of the application of macromolecule water absorbent resin was conducted on the dry land. Root vigor and leaf relative water content (leaf water potential) and improved the photosynthetic physiological characteristics and increased yield and water production efficiency of the wheat. The root vigor with the application of a 54 kg/hm^2 dosage of macromolecule water absorbent resin was found to be the strongest in the jointing, booting and grain filling period and the leaf relative water content with this dosage treatment was also the greatest. During the jointing and booting periods, the photosynthetic rate, transpiration rate and leaf water use efficiency with the application of a 54 kg/hm^2 dosage of macromolecule water absorbent resin were found to be the highest. In summary, the effect of the application of a 54 kg/hm^2 dosage of macromolecule water absorbent resin was found to be the most effective.
