不同磁化强度处理对苜蓿生长和产量的影响
Effects of Different Magnetic Intensity Treatments on Growth and Yield of Alfalfa
摘要
Abstract
[Objective] Alfalfa as the main crops cultivated in the pastoral areas of Xinjiang, due to drought, high evapotranspiration and other special natural conditions, many problems such as excessive irrigation quota and high consumption and low efficiency resulted in it.Based on the drip irrigation technology, through the magnetic treatment on the magnetization under the growth and yield of alfalfa, this project aims to clarify the law of alfalfa growth under the condition of magnetization and provide data support for high quality and high yield of alfalfa and reasonable irrigation system.[Method]Setting 1,000 GS, 3,000 GS and 5,000 GS of three different magnetization, irrigation quota of 3,600 m3/hm2, and irrigation quota of 300 m3/hm2, the growth index and yield index of alfalfa under different magnetic intensities were monitored and the changes of plant growth and yield index were analyzed, thus understanding the effect of magnetization treatment on alfalfa growth.[Result]The results show ed that magnetized water irrigation promoted the growth and yield of alfalfa, compared to the first and second stubble, the average height of magnetized water treatment were 3.4 cm and 7.4 cm higher than, the average stem diameter of the control group.The average stem diameter was 0.17 mm and 0.25 mm higher than that of the control and the average yield compared with the control group was more than 0.23 kg/m2 and 0.14 kg/m2.The correlation between yield and plant height and stem diameter was linear (R=0.96), and the fitting equation was Y=-0.883,4+0.017,7 X1+0.137,4 X2.[Conclusion]In the alfalfa first year growth period, magnetized water irrigation can promote the growth and yield of alfalfa, but with the magnetization increase, yield would decrease, and the alfalfa is a perennial crop, reasonable selection of magnetization still needs to be further researched in selecting reasonable magnetization intensity in the future.关键词
