Effects Of Sowing Patterns On Growth And Yield Of Winter Wheat With Drip Irrigation

Belongs to the typical irrigated agriculture in Xinjiang,drip irrigation of wheat planting patterns is a new type of modernization.There are different in planting pattern of drip irrigation of wheat planting patterns,compared with traditional wheat planting.Therefore,it is important to study the drip irrigation of wheat planting patterns,in order to improve the potential productivity of wheat in Xinjiang.This research focused on effects of sowing patterns on growth and yield of winter wheat with drip irrigation combined with local characteristics in Xinjiang.Four planting patterns were set up:#sowing,wide and narrow row sowing,trench planting and equal row sowing.The effect of different sowing methods on drip irrigation of wheat was studied,which provided some technical support for drip irrigation of wheat in Xinjiang.The main results were as follows:1.Sowing methods have an obvious impact on the growth and development of wheat.The maturity of the#sowing has a certain extension trend compared with other methods,its mature relatively later.The amount of tillers per plant in different treatments increased with the growth and development,and became stable at heading stage.There were more tillers per plant at the different growth stages,and the maturity period was also higher.There were the most seedling of#sowing,and the total stem changed with the growth of wheat,presented the single peak curve.The peak was appeared in elongation stage,and with significantly differences between the different sowing methods in elongation stage and heading stage.The effect of different sowing methods was different.2.The effects of sowing methods on dry matter of wheat were different at different growth stages.There were not significantly differences between the wintering stages and elongation stages of the dry matter weight by the sowing methods.But there were significantly differences in heading stage and mature stages.The ratio of main stem and tiller maintained at 95.5%higher value,reduced the amount of inefficient tillers and increased spike number of main stem,and promoted more accumulation of dry matter at heading stage and maturing stage.3.Sowing pattern has a significantly effects on wheat grain yield,#sowing pattern obtained more grain,increase range from 5.7 to 22.2%.From the yield components analysis,in#sowing pattern,amount of harvesting panicles per unit area is relatively low.And thousand seed weight was not significant difference,but there was about 11.3%increase in the ear grain number.Therefore,in the case of ensure wheat ear number per unit area,can be achieved by increasing ear grain number of wheat yield increase,this may be the main reason of#sowing pattern can obtain high yield.4.In the total cost of mechanical seeding,although drip irrigation and labor,and so on,the#sowing pattern cost a total of 975 yuan/hm~2;high grain yield about 4.7-13.8%was achieved by#sowing pattern,which eventually received 5067.9 yuan/hm~2,compared to an increase benefits of 22.7%.
