高效营养保水剂在大田玉米生产上的试验效果

Experimental Results of the Efficient Nutritious Water-preserving Agent on Corn

田间试验表明，高效营养保水剂有促进玉米种子萌发、抗旱保苗，促进茎叶生长和根系发达，增加叶绿素含量和增强光合功能的作用，经受了２０００年大旱的考验，值得在生产上推广应用．

Combating drought for keeping a full stand of seedings has always been one of the main measures of agricultural production. The efficient nutritious water-preserving agent is a compound with water-preserving materials as the main matrix. Having been tested in the field experiment, it shows the functions of improving the germination of corn seeds, combating drough and keeping a full stand of seedlings, promoting the stem and leaves growth as well as the development of the root, in- creasing the content of chlorophyll and enhancing the photosynthesis. It is worth popularizing and ap plying in agricultural production.
