Effect Of Kehan98 On Winter Wheat Cultivation Physiology And Yield Character

Two experiments are designed in the research, one is experiment of dosing ratio between kehan98 and fertilizer, the other is winter wheat is sprayed with Kehan98 super absorbent polymer in different growth period. In the first experiment, mathematics model (regression equation) is founded with systems engineering, studying effect of dosing ratio between kehan98 and fertilizer. Plant characteristic, physiological traits, yield and quality of winter wheat are studied with randomized block design and eight treatments in the second experiment. So they can supply a theoretical basis for wheat production. The main results as follows:l.In the first experiment, mathematics model (regression equation) is founded, main effect, two-factor interaction and marginal yield effect of kehan98 and fertilizer are analyzed, agricultural project of the most yield is discovered, that is, x1= -1.414, X2= -1.2.Seed dressing with kehan98 can improve the seedling rate which is more than control by 3.98 percent, lower plant height which is shorter than control by 2.52 percent. The number of tiller and secondary root separately is more than control by 4.95 percent and 6.92 percent, wet and dry weight of the single stub is heavier than control by 8.73 percent and 8.9 percent, root-cap rate is 1.18 times size of control.3.Kehan98 have a regulating effect on flag leaf physiological traits. It can boost water-retaining capacity which is higher than control by 7.58 to 17.2 percent, reduce water loss of flag leaf, improve ratio of free water and bound moisture, WUE of treatment 4,7,8 is larger than control by 27.45 percent, 28.49 percent, 34.97 percent, particularly effect of treatment 8 is best. It can enhance chlorophyll content, maximum chlorophyll content increased 32.76 percent, decrease MDA content, make MDA the gather speed slow, so it can delay leaf decrepitude, keep photosynthesis preferably.4.Kehan98 can increase the dry matter amount of stem and sheath, improve their capacity of holding and exporting the material.5.Through the kehan98 treatment, wheat ear trait can improve. Its ear length becomes longer than control by 1.9 to 17.6 percent, the sterile spikes become lower than control by 26.05 percent, the non-sterile spikes are higher than control, the treatment 8 is the most significant and is higher than control by 3.29 per ear, the grains per ear become more than 3.34 grains, weight of 1000 grains is heavier than control by 5.60 to 9.82 percent, thetreatment 8 get very significant, more than control by 9.82 percent.6.Kehan98 has an effect on the yield. Its yield increases from 2.08 percent to 20.31 percent, among them, the treatment 8 increases maximum, which is 20.31 percent. Inaddition, grain quality has a certain improvement through kehan98.
