摘要
为了探讨矿物源黄腐酸钾对苹果膨大期生长、品质及土壤的影响,确定矿物源黄腐酸钾在苹果生产上的最佳用量,开展了矿物源黄腐酸钾根部冲施试验。结果表明:矿物源黄腐酸钾根部冲施可提高苹果可溶性固形物含量、果实横径、单果重,改善土壤酸化,提升土壤有机质含量;其中,可溶性固形物含量、单果重提高显著,以冲施矿物源黄腐酸钾6 kg/667 m^(2)效果最佳,可溶性固形物含量比对照提高了19.01%,单果重比对照提高了10.07%;产值达到23246.3元/667 m^(2),比对照经济效益提升了1475.8元/667 m^(2);利润提升以冲施矿物源黄腐酸钾2 kg/667 m^(2)最高,较对照多1510.9元/667 m^(2)。综合苹果生长性状、产量和经济效益分析,矿物源黄腐酸钾在苹果上的适宜施用量范围为2~6 kg/667 m^(2)。
In order to know the ef fects of mineral source potassium fulvate on the growth, quality and soil of apple during the expansion period, a root fl ushing experiment of mineral source potassium fulvate was conducted to determine the optimal amount of mineral source potassium fulvate in apple production. The results showed that the application of mineral source potassium fulvate to the roots could increase the content of soluble solids,fruit diameter, single fruit weight, improve soil acidification, and increase the content of soil organic matter,especially for the content of soluble solids and single fruit weight increased signifi cantly. Application 6 kg/667 m^(2)of mineral source potassium fulvate obtained the best ef fect. The content of soluble solids increased by 19.01%and single fruit weight increased by 10.07% compared with the control. The economic benefits reached 23246.3 yuan/667 m^(2) that was 1475.8 yuan/667 m^(2) higher than the control. The highest profit increase was achieved by fl ushing 2 kg/667 m^(2) of mineral source potassium fulvate, which was 1510.9 yuan/667 m^(2) more than the control. According to the analyses of apple growth characteristics, yield and economic benefi ts, the proper application extent of mineral source potassium fulvate on apple was 2 ~ 6 kg/667 m^(2).
