含腐殖酸水溶肥在小白菜上的应用效果研究

Study on Application Effect of Water-soluble Fertilizer Containing Humic Acid on Pakchoi

为了验证含腐殖酸水溶肥在小白菜上的应用效果,在合理施肥的基础上开展了喷施该肥料的田间试验。结果表明,喷施含腐殖酸水溶肥的小白菜产量可达39142.9 kg/hm^(2),比空白对照增产3952.4 kg/hm^(2),增产率为11.2%,纯收益增加10507.2元/hm^(2)。说明在合理施肥的基础上喷施含腐殖酸水溶肥,对小白菜具有比较明显的增产作用和较好的经济效益。

In order to verify the application effect of water-soluble fertilizer containing humic acid on pakchoi,a field experiment was carried out on the basis of rational fertilization.The results showed that the yield of pakchoi sprayed with water-soluble fertilizer containing humic acid could reach 39142.9 kg/hm^(2),which was 3952.4 kg/hm^(2)higher than that of the blank control,the yield increase rate was 11.2%,and the net income increased by 10507.2 yuan/hm^(2).It showed that the application of water-soluble fertilizer containing humic acid on the basis of rational fertilization had obvious yield-increase effect and better economic benefit on pakchoi.
