A SiErTe Fertilizer Research Suitable For Production Of Rice Paddies Rape

Using field plot test, studied the Application Effect difference between the ratio of NPK Sierte Fertilizer and current use of fertilizer, and the effects of Rapeseed growth and yield used Sierte fertilizer and single fertilizer mixed with division in the total nutrients in certain circumstances.The results showed that, Effect test of different formula fertilizer, sierte fertilizer treatment increased by20.8%than the conventional fertilization, increased by10.5%than the current formula fertilizer treatment; In the different nutrient ratio experiment,4treatmented with sierte fertilizer deployment of N:P2O5:K2O=12:6:7, the grain yield, nutrient accumulation, oil yield and protein yield were the highest, but the grain of flax acid, linoleic acid, oil and protein content was not significantly different. Agronomic traits of rape in different growing stage were affected using different fertilizer and nutrient ratios,including plant height, node number, branch number, pods per plant had more effect on grain yield,1000grain weight had little effect on grain yield. With no fertilizer treatment as the base of the apparent N recovery efficiency, agronomic efficiency, physiological efficiency and partial factor productivity, In the experiment of different fertilizer effect, all with sierte fertilizer treatment was higher than that of the current use of formula fertilizer and farmer fertilization treatment; In the experiment of different nutrient ratio effect,4treatmented was the highest,all with sierte fertilizer allocation N:P2O5:K2O=12:6:7, The treatment of potassium and phosphorus apparent use efficiency, agronomic efficiency, physiological efficiency and partial factor productivity were low, This was mainly with phosphorus, potash fertilizer higher.
