‘罗麦8号’高产栽培施肥量数学模型探讨
A mathematical model of fertilizer rate in high yield culture of ‘Luomai 8'
摘要
Abstract
The pilot study on fertilizer rates in high yield culture of wheat was carried out,and a mathematical model of fertilizer rate in culturing a new wheat cultivar 'Luomai 8' was established by using a regression model of quadratic polynomial. The result showed that the optimal fertilizer rates were 290.91-302.28 kg/hm2 N,74. 07 - 86. 02 kg/hm2 P2O5 and 71.82-96.18 kg/hm2 K2O;The descending order in contribution ratios of fertilizer factors to 'Luomai 8' yield was N＞P＞K.关键词
