Furrow Sowing Wheat Moisture Content And Physiological Ecology Research

This study in Jincheng of Shanxi high town east village in Shanxi Agricultural University experimental base of wheat for two years(2013?2015).Experiments to ordinary line seeding for the control group,furrow sowing planting as the experimental group,respectively in each growth period of wheat,measured the wheat processing pattern of 0?300 cm soil moisture distribution and variety of the total evaporation,and in different planting mode,the yield index of wheat(grain number per panicle,panicle number per hectare,thousand seed weight and yield per hectare),and the photosynthetic rate of wheat,diurnal temperature changes and other indicators,to study the planting mode of winter wheat moisture transfer and the influence of the physiological characteristics and the influence of seeding mode effect under different rainfall variability.In the aspect of soil moisture characteristics in trench planting mode.Research shows that winter wheat in the 0?300 cm soil layer in the change of growth period presented oblique "W" type(left lower right high).Furrow sowing overall soil moisture content is higher than the control group,and can promote the deep soil water vertically upward,soil water use is more reasonable;Its mode unique surface morphology can effectively reduce the soil temperature near the ground,reduce wheat between evaporation,soil water use efficiency increased accordingly.In the furrow sowing cultivation about material accumulation and distribution in Wheat.Research shows that the furrow planting significantly increased the pre winter tillering value of Winter Wheat in southeast of Shanxi Province,significantly increased the elongation stage groups to the total number of stem tillers,flag leaf length and width is significantly higher than conventional drilling,the area also increased accordinglv;On the dry matter accumulation and growth of each period of dry matter accumulation was higher than that of control group wide furrow planting pattern,but in the jointing stage and heading stage than other periods had significant difference,the experimental group than in the control group the total dry matter were increased by 25.49%and 15.81%,28.43%and 17.60%.Furrow sowing cultivation,during the winter wheat grouting rate than ordinary line has improved significantly,grouting time becomes longer.Compared with the control group,the difference was significant.Light distribution and photosynthetic characteristics of wheat in furrow sowing,compared with ordinary line,it improved the wheat leaf area index(LAI),in each level LAI were higher than the control group,and the most significant difference in 60?80 cm.Furrow sowing after planting the flowering period of chlorophyll content were higher than the control group,21 days after flowering it achieve the highest,two deal with the most obvious difference at this point,flag leaf photosynthetic rate furrow sowing planting patterns of overall change is higher than the ordinary line.7 days after flowering it reached the highest value,and maintained high rate in 7?21 days.From booting to anthesis,population photosynthetic rate stable,after the slow decline after anthesis it reduce rapidly,change trend between processing remain identical;.Furrow seeding planting group filling stage grouting rate higher than that of control group,extend the time of the grouting.In the aspect of the yield components and quality of furrow sowing wheat,the furrow planting pattern of southeast Shanxi winter wheat into a number of ears,grain number per spike and thousand?grain weight increase,the ear number of which the most obvious difference,and improve the protein content of wheat grain,improving the quality of the wheat.
