Effects Of Sowing Irrigation And Nitrogen Fertilizer On Grain Yield And Quality Of Winter Wheat Under Straw Return To Soil

Fertilization not only improve crop yield but it also increasing the yield of straw,straw containing nitrogen,phosphorus,potassium and other essential plant macronutrients.Crop straw contains large quantities of organic fertilizers.Application of straw improved soil structure and texture which increase crop yield.Reduceduse of straw burning damage to the ecological environment,improve the soil,reduce the waste of agricultural resources.The experiment was conducted on the land of Huaibei Plain at Bozhou,Mengcheng County Agricultural during October 2013--2014 in June.The poor tilth quality and heavy clay soil was not conducive to crop yield and quality.The test materials used to promote the wide range of good stars 66 species in the area to explore straw chopper,water and irrigation Sowing Nitrogen Application on yield and quality of wheat.Purpose of the experiment was to explore the full amount of crushed straw to field,planting irrigation water and Nitrogen Application for yield and quality of wheat.Crushed straw was applied to field to improve crop production to provide a theoretical basis.The results are as follows:1.The total amount of crushed corn stalks and sowing irrigation significantly(p<0.05)affected wheat germination rate.The germination rate in those plots which were treated with wheat straw was significantly(p <0.05)lower than without straw plots.Planting irrigation level emergence was significantly(p < 0.05)higher than sowing irrigation.Plots treated straw without irrigation gave low value for seedling(average 51.32%),while irrigation water without straw gave high value for seedling(average 88.28%).stalk incorporated plots gave high returned to field and Seedlings were significantly(P <0.05)less than without straw treatment.reduced straw before winter wheat seedlings number was not conducive to the formation of the size of the seedlings,without straw increased the size of Miao number.Straw incorporation,straw obstacles,water shortage and quality of sowing were wheat emergence factors,the impact of water shortage on the emergence of which> Straw impede> sowing quality.Nitrogen Management on the emergence of wheat is not obvious.Reducingthe basic seedling wheat straw,irrigation water increased the basic sown wheat seedlings,interactionsexistbetween straw incorporation and irrigation water for wheat sowing basic seedling?2.Straw,planting irrigation and Nitrogen Application after flowering period increased chlorophyll content.Chlorophy ll content rate in those plots which were treated with wheat straw during winter was greater than treatment without straw.After winter period the average growth rate of chlorophyll faster than without straw treatment.The rate of decline is less than the late treatment without straw.Similarly irrigation water with straw treatment after postponing increased of leaf area.no more than the rate of increase during winter sowing irrigation water.Under no irrigation water seeding conditions,leaf area was larger than the straw treated leaf area of the field.3.Straw increased the thickness and length between first and second internodes and also increased the length between the first quarters.Under non-irrigation conditions,increase plumpness between internodes and under irrigation conditions,the section between plump nessde clines.While reducing section between plumpness,sowing irrigation water increases plumpness among internodes which helps to increase irrigation water between sowing section plumpness.No irrigation water reduces the length between internodes but the value o lodging area has increased.low irrigation and N2 treatment gave the maximum length.With the application of different nitrogen doses a clear difference was observed between lodging rate and lodging area.N2 treatments gave high value for lodging area of about 80%.Sowing irrigation water with straw incorporation increased internodes length,reduced the lodging degree and reducing the lodging area.4.Plots treated with stalk significantly(p <0.05)affected wheat spike.Higher plant spikes were observed in straw treated plots as compared to without straw plots.Tiller numbers were found greater than without straw treatment.Straw and shrub planting water promotes tiller.All of the main stem and straw treated under a primary and the second primary tiller number was not significant.Similarly the 2nd,3rd and4 th levels tillers were found significant(p <0.05).The same level without straw,theirrigation water significantly increased sowing stem,a tiller of solid grains,and grain number of 2 tillers little effect.Corn straw increased significantly stem,atillersinglepanicle weight(p <0.05),2tillerson grain weight per panicle obvious.The total amount of cornstalks to field planting and irrigation water efficiently to help increase the wheat spike and economic yield of wheat,Sowing irrigation water to improve wheat yields high ermargin.Sowing irrigation water to improve wheat yields high ermarg in.5.In corporation of stalk straw significantly(p <0.05)affected spike lets and more spike lets were found than without straw treatment.Irrigation at sowing time produced more spike lets than planting irrigation.Plants produced 1 tiller in straw incorporated plots gave a huge difference between spike lets and spike lets.At the stage of 2 tiller,more spike lets were observed in straw treated plots than without straw treatment.At the field level straw planting irrigation at 2 tiller spike lets significantly(p <0.05)degraded more than no planting irrigation treatment.N4 with no irrigation gave maximum spike lets.Biological yield under straw,higher economic yield and harvest index without straw treatment.Without straw,without sowing irrigation water with the change of nitrogenous fertilizer increased the value of economic output.6.Protein content of wheat was not significantly(p> 0.05)affected by straw incorporation.The protein content of straw without irrigation is slightly higher than without straw planting irrigation.Less starch content was observed than stalks starch content.Straw treatment significantly(p <0.05)reduced sedimentation.At field level planting irrigation value was not greater than sowing irrigation treatment.Seed hardness under wheat straw treatment was Significant(p <0.05).At field level planting irrigationand irrigation at sowing time gave different value for seed hardness.
