“3414”施肥处理对小麦溶剂保持力的影响

Effects of ‘3414’ Fertilization on Wheat Solvent Retention Capacities

通过"3414"施肥试验研究分析氮磷钾对小麦溶剂保持力的影响。回归分析得出三元二次回归方程,计算出4种SRC的回归方程。结果表明,除水SRC外,其他3种溶剂保持力回归分析均具有(可靠)拟合性。通过对3种单因素在同条件下的方差分析,氮对水SRC影响不大,对其他3种SRC影响达极显著水平;磷钾对4种SRC的影响均不显著。表明了3种肥料因素中氮对小麦SRC的影响较大,其他两种因素对SRC影响不明显,说明SRC受施肥水平的影响。

A 3414 fertilizing model was used to study the effects of N,P2O5 and K2O fertilizers on these SRCs.A regression model of Y=b0＋b1x1＋b2x12＋b3x2＋b4x22＋b5x3＋b6x32＋b7x1x2＋b8x1x3＋b9x2x3 was obtained and the regression of each SRC was calculated.The results showed that the F value of the regression of each SRC was ＆gt;F0.05 or ＆gt;F0.01 except the WSRC which had an F value ＆lt;F0.05.It demonstrated the fact that SRCs were influenced by fertilizing.N fertilizer showed significant influences on LASRC,SCSRC and SSRC but no influence was found on WSRC. With the increase of N level, LASRC, SCSRC and SSRC levels increased. However, neither P nor K showed significant effects on all the SRCs. Influence of N level was the greatest and P and K showed no significant influence on wheat quality.
