The Growth And Development Of Spring Maize Influenced By Different Drip Irrigation Mode

Comprehensive drip irrigation technology corn supporting model,further exert the synergies,is a technology problem that at the agricultural invitation and economic development.That is becoming a research hotspot.In this paper,through combining corn spacing planting and drip irrigation,found their impact on growth and yield of spring corn.Researching of could draw few conclusions.1)The distance and drop flow with different level has a significant effect on growth rate,and the interaction between them is obvious.2)The growth rate and distance has a cubic curve;Growth rate and the drop flow has a quadratic curve curve.3)Through the combination of flow and planting patterns,we can control the growth rate of maize.The commended planting pattern is equidistant four-row,flow is 1.1 L/h.4)The corn panicle length,panicle weight and yield per plant were impacted by flow and distance with different levels,and their interaction is obvious;Ear width of corn were impacted by flow and distance with different levels,but the their interaction is not obvious;Row grains hasn't any relationship of flow and distance;Hundred-grain weight is affected by the different levels of the distance,but is not affected by drops of flow.For each factors,in addition to flow and distance,also affected by other factors.At the same time,through the leaching-pond and the method of orthogonal experiment,explored the effects of flow,planting patterns and soil type on spring corn.Study found that.1)The soil types is the main factor on maize plant growth in the late seedling stage and jointing stage.And in the early jointing stage flow the main factor;2)Soil types is the main factor of panicle length,ear width,panicle weight and hundredgrain weight in all factors.The most beneficial to maize panicle length,ear width and panicle weight is red clay.Shajiang black soil is benefits the increase of hundred-grain weight.The optimal combination of panicle length is M₂S₂Q₂.The optimal combination of ear width is M₃S₂Q₃.The optimal combination of panicle weight is M₂S₂Q₂.The optimal combination of hundred-grain weight is M₂S₁Q₂.
