紫色马铃薯“3414”肥效研究
Study of "3414"Fertilizer Efficiency Test of Purple Potato
摘要
Abstract
The research aimed to solve the problems of blind and excessive fertilization and improve the utilization rate of the fertilizer.[Method] Purple potato KX-5 was taken as material.3414 full implementation plan design was adopted to study the fertilization model of purple potato in southwestsecond quarter area in the spring.[Result]Optimum ternary quadratic equation of fertilizer effect function of the yiele of the purple potato (Y) and fertilizer level (X1-N,X2-P2O5,X3-K2O) was Y =1 352.67-89.78X1 + 14.17X2 + 144.98X3-8.03X12 _5.07X22-3.83X32 + 36.46X1X2-2.54X1X3-12.95X2X3.And the application amount of N,P2O5 and K2O was 61.80,73.65 and 131.25kg/hm2.[Conclusion] The research could provide the guidance for ec onomic fertilization of purple potato production in the local area.关键词
