摘要
为验证豇豆测土配方施肥的准确性和本地配方肥最佳施用量,对比、检验测土配方施肥效果,验证和优化肥料配方,为测土配方施肥技术及配方肥的大面积推广应用提供科学依据。本研究设置了配方施肥(1)(T1)、配方施肥(2)(T2)、常规施肥(T3)和无化肥(CK)4个处理。结果表明,T1、T2和T3均比无化肥(CK)增产增收;与T3相比,T2增产效果较为明显,平均增产6306 kg/hm^(2),节约化肥成本8988元/hm^(2),节本增效42198元/hm^(2)。由此可见,配方施肥较常规施肥增产增效明显,达到节本增效的目的,促进农业绿色高质量发展,说明此施肥配方适宜在三亚市豇豆生产中推广。
The effect of soil testing formula fertilization was compared and tested to verify the accuracy of soil testing for-mula fertilization of cowpeas and the optimal application amount of local formula fertilizer,and the fertilizer formula was verified and optimized to provide a scientific basis for the soil testing formula of fertilization technology and the large-scale promotion and application of formula fertilizer.In this experiment,four treatments were set up:formula fertilization①(T1),formula fertilization②(T2),conventional fertilization(T3),and no chemical fertilizer(CK).The experimental results showed that T1,T2,and T3 increased yield and income compared with CK.Compared with T3,the yield-increasing effect of T2 was more distinct.The average yield increase per hm^(2)was 6306 kg,the cost of chemical fertilizer was reduced by 8988 yuan,and the cost savings and efficiency increase per hm^(2)was 42198 yuan.This result indicated that formula fertilizer application could increase yield and efficiency more than the conventional fertilizer application,achieve the goal of saving costs and increasing efficiency,and promote green and high-quality agricultural development.This result indicated that the formula fertilizer ap-plication was suitable for spreading in cowpea production in Sanya.
