Experimental Study On Fertilizer Effect Of Corn Field In Xinhua Farm Of Heilongjiang Province

Fertilization can improve crop yield and quality,but over fertilization and insufficient fertilization can lead to a decline in agricultural output and an unnecessary loss of quality.How to improve the efficiency of fertilizer use and reduce the input cost of fertilizer,the most suitable fertilizer input to achieve the maximum economic benefit becomes the focus of the research on fertilizer effect.Test in Hei Longjiang He Gang Xinhua farm,this study set up two fertilization modes(normal fertilization soil testing fertilization)and five fertilizer experiment design(N1P1K1 N0P1K1 N1P0K1 N1P1K0 N0P0K0),Through the determination of drying grain yield,leaf yield,grain and straw indices such as total nitrogen,total phosphorus and total potassium,analysis of corn field in the region of N,P,K fertilizer fertilizer effect,the results of the analysis concluded that:1.To improve the yield of corn seeds and straw,and to increase the content of total nitrogen,total phosphorus and total potassium in grain and straw.The grain yield,crop yield and total nitrogen,total phosphorus and total potassium content were the highest in total fertilizer application.2.3 the absorption of N,P and K elements of maize was greater than that of the lack of fertilizer,and there was no significant difference between the formula fertilization and conventional fertilization techniques.The 100 kg economic yield of full fertilizer is higher than that of a certain kind of fertilizer.There was no significant difference between conventional fertilization techniques and fertilization techniques.3.N fertilizer utilization rate of soil testing average utilization rate of fertilizer N fertilizer is higher than conventional fertilization was 11.15%,P fertilizer utilization rate of soil testing formula fertilization was 16.72% higher than the conventional application of fertilizer P fertilizer,K fertilizer utilization rate is higher than conventional fertilization soil testing formula fertilization by 15.90%.4.According to the data of the three operation stations,the yield of b-n1p1k1 was the highest and the yield of stem and leaf was the highest,and the yield of A-N0P0K0 was the lowest.The total nitrogen was the highest in B-N1P1K1 and the lowest in B-N0P1K1.The total phosphorus was the highest in B-N1P1K1,and the lowest in B-N0P1K1.The total potassium was the highest in A-N1P1K1,and the lowest in B-N0P0K0.5.In the case of B-N1P1K1,the total nitrogen of stem leaves is the lowest under B-N1P0K1.Stem and leaf phosphorus A-N1P1K1 and B-N1P1K1 were the highest in the case of A-N0P0K0.The total potassium of stem leaves was the highest in B-N1P1K1,and lowest in B-N0P0K0.6.The distribution ratio of seed and stem and leaf N fertilizer was highest in B-N1P0K1,and lowest in B-N1P1K1.The distribution ratio of P fertilizer was highest in B-N0P0K0 and lowest in B-N0P1K1.The distribution ratio of K fertilizer was the highest in A-N1P0K1,lowest in N1P1K0 and B-N0P0K0,and the distribution of K fertilizer was used in the application of K fertilizer.7.All three operation stations are the best economic benefit of the formula fertilization application B-N1P1K1.Operation station A-N0P1K1 has the lowest economic benefit.On the whole,the economic benefit of conventional fertilization is not as good as that of the formula,and the total economic benefit of the formula fertilization is 99.86 Yuan higher than that of conventional fertilization.
