doi:10.7668/hbnxb.2008.S2.066

Abstract

Abstract: Use the ″3414″regression design model to studied the effect of N,P and Kfertilizer application on soilnutrient dynamic change and yield in wheat through field experimentation and chemical analysis. The results indicatesthat,the change of soil nutrient content exhibits a definite rules and a reasonable application of fertilizer could increasewheat yield by 20. 57 % - 41. 39 %,the treatment of N2P2K2 (N 255 kg/ ha,P2O5 150 kg/ ha,K2O 150 kg/ ha) was thebest.And at the base of experiment,the yield model of the fertilizers is Y= 5 720. 338 + 5. 142 8N + 12. 028 7P + 7. 3229K- 0. 012 1N2 - 0. 038 7P2 - 0. 021 6K2 + 0. 008 8NP - 0. 000 5NK- 0. 002 8PK,and its top yield is at 8 083. 16kg/ ha while the application quantity of N,P2O5 and K2O is at 275. 17,181. 10 and 154159 kg/ ha; Its the economical andreasonable quantity of fertilizers application are 212. 31,152. 23 and 117. 51 kg/ ha while the wheat yield is 7 985. 18kg/ ha,the profits of applying fertilizer is 948. 62 yuan/ ha.

Key words: Application quantity of fertilizer , Soil nutrient , Wheat yield , Fertilizer effect equation
