Effects Of Special Liquid Concentrated Fertilizer(Injection) For Walnut On Walnut Growth And Production

Based on the sampling and analyzing of the soil of walnut growing area in Yijun county,the methods such as natural sampling?laboratory analysis?field assessment are integratedly used in this paper.To learn the nutrient requirement of walnut named ”Qingxiang” from Yijun county walnut planting base,we chose the liquid concentrated fertilizer for walnut which is suitable for the local soil nutrient environment and satisfies the requirement of nutrient,to begin the experiment which test the effect of fertilizer.The experiment started by selecting 60 walnut trees as fertility test target: 20 saplings(3-5 years),20 early fruit(6-10 years)and 20 high fruit(11 years or more).Then using treatment options for non-fertilizing?normal fertilizer and liquid concentrated fertilizer in different to find differences in total output and single output.The results were as follows:1.The liquid concentrated fertilizer ingredients: pH 3.73,Ammonium nitrogen 842.03 mg/ L;Nitrate nitrogen 758.96 mg/ L;Potassium ion 18.96 g/ L;The iron ion18.39 g/ L;Zinc ion 6.31 g/ L.2.Walnut special liquid thickening fertilizer(injection)on the growth of walnut trees have a certain role in promoting,especially the results of the percentage of branches with fruit.The percentage of branches with fruit was increased by 3.7 %-43.9 % compared with the use of ordinary fertilizer and 5.60 %-116.1 % compared with non-fertilizing.Application of walnut liquid special fertilizer can significantly increase the amount of walnut tree new branches,it was 1.10-1.47 times the amount of common fertilizer and 1.20-2.08 times of non-fertilizing,the early fruit of the walnut trees had the most significant effect.The growth length of walnut trees in saplings and early fruit plants was significantly higher than that of control treatments.The results showed that the number of fruits per fruit was significantly higher than that of the control treatments,and the results of lateral bud rate were increased by 4.52 %-9.05 %.There was a positive correlation between the results of walnut trees lateral bud rate and the number of fruit per branch.3.The single output of liquid concentrated fertilizer was increased by 20 % to 25 % compared with using ordinary fertilizer.The moisture content rate of the walnut,using liquid concentrated fertilizer,is the lowest in three project.In this case,the production of walnut increased about 21 %,and the production of the walnut without scarfskin increased about 22 %,and the production increased by about 25 % after drying,the best effect on walnut trees in early fruit.Then conclusions are as follows: the application of liquid concentration fertilizer in the experiment could significantly increase local walnut production,thus to drive walnut planting economic growth in Yijun country.
