Experimental Study On Fertilizer Of Rice And Corn In Longjing By "3414"

Soil nutrient content and fertilizer have a crucial impact on crop growth and development, Thereby affect the income of farmers. But in recent years, fertilization bottlenecks and fertilizer waste which caused environmental problems attract attentions. In order to serve the actual agricultural production better, we conducted fertilizer effect field trials which focus on the effects of different fertilizer levels on rice and corn of Longjing fertilizer use efficiency and yield.Fertilizer effect field experiment is the fundamental way to find the best fertilizer quantity, fertilization proportion and fertilization methods of various crops. We use "3414" field experiment in3years to study the best fertilization system and the best fertilizer quantity of corn and rice. The main results are as follows:(l)By the study of "3414" fertilizer experiment on rice, we get the best application amount on N、P、K of corn.The results show that when the best fertilizer quantity of rice are:N:130kg/ha2, P:70kg/ha, K:135kg/ha it can achieve the best yield and economic traits of crop fertilization model.(2)The study of "3414" fertilizer experiment on rice show that when the fertilizer quantity of corn are N:150kg/ha, P:60kg/ha,K:90kg/ha, the yield and economic are the best.
