利用"3414"试验确定龙江农场热垦525最佳施肥量的探讨
Fertilizer Recommendation of Rubber Latex/Timber Clone Reken 525 Based on "3414" Field Experiments in Longjiang Farm
摘要
Abstract
Fertilizer recommended rates were simulated by the models of three-factor, one-factor, liner and platform based on two year's"3414" field experimental data of Reken 525 in Longjiang Farm. The results showed that the optimum fertilizer rate of three-factor model were N 0.135 7 kg/tree, P2O5 0.064 8 kg/tree and K2O 0.082 1 kg/tree. According to the characteristics of production trends, the optimum fertilizer rate of one-factor model were N 0.105 1 kg/tree, P2O5 0.106 0 kg/tree and K2O 0.103 9 kg/tree by comparing one-factor and liner and platform model. Some optimum fertilizer rate indicators of three -factor model were higher than one -factor model. Comprehensive consideration, the optimum fertilizer rate of Reken 525 initially identified as N 0.105 1-0.135 7 kg/tree, P2O5 0.064 8-0.106 0 kg/tree and K2O 0.082 1~0.103 9 kg/tree.关键词
