Effect of Different Flow Rate and Laying Distance of Drip Irrigation Belt on Fresh Corn
In order to clarify the effects of different drip irrigation belt laying methods and flow rates on the growth and yield of fresh corn,and to provide reference for the optimal cultivation of fresh corn in Beijing.Field tests were conducted with two factors:the flow rate of the emitter and the laying dis-tance,and four treatments were set up:the flow rate of the emitter was 2.7 L/h for T1 treatment,and the laying distance of the capillary was 60 cm;For T2 treatment,the drip flow rate was 2.7 L/h,and the capillary laying distance was 40 cm.In T3 treatment,the drip flow rate was 1.38 L/h,and the capillary laying distance was 60 cm.In T4 treatment,the drip flow rate was 1.38 L/h,and the capil-lary laying distance was 40 cm.The results showed that compared with T1,T2 and T4,the straw dry matter content of T3 treatment on June 7 was increased by 7.62%,2.10%and 5.34%,respectively.The net output was increased by 21.09%,27.10%and 5.28%,respectively.Soluble protein was increased by 11.05%,21.26%and 4.25%,respectively.The applicator flow rate of 1.38 L/h and the distance of capillary laying of 60cm were beneficial to the growth,yield and quality accumulation of fresh corn.
