Abstract  With the development of fertilizer industry, the productions of compound fertilizer in China increase year by year, and the production process has also changed a lot. 　　A pot experiment was conducted to study the effects of compound fertilizers by different processes on yield and yield quality of pakchoi (Brassica chinensis L.) for three consecutive years. 　　The results showed that the nutrients amount of compound fertilizers by different processes were the same, while there were significant differences in the effective nutrient content (P＜0.05). Compared with treatment without fertilizer, different process compound fertilizer treatment increased the yield from 48.49% to 122.93%. AZF fertilizer (15-15-15S) and granulated fertilizer (15-15-15S) promoted the plant growth, but decreased the contents of proteins, free amino acids and increased the content of nitrate with poor quality. Resin-coated fertilizer (18-9-18S) and elemental fertilizer promoted yield quality, root activity and chlorophyll content, but lowered yields. The path coefficient analysis showed that the direct path coefficient sizes of the effective nutrient content in different compound fertilizer for yield were: NH4+-N (1.985 5)>K+(0.800 2)>Ca2+(0.687 1)>pH(-0.119 6)>NH4+-N/NO3--N(-0.354 0); for nitrate content were: pH (0.929 8)>S(0.217 6)>NH4+-N/NO3--N(0.146 1). Moreover, the nitrate content in leaf was significantly negative correlated with free amino acid content and SPAD value (P<0.05). 　　In conclusion, Minar process fertilizer (15-15-15S) was more beneficial to the high-yield and high-quality production of pakchoi, and improvement of soil fertility.

不同工艺复合肥对小白菜产量和品质的影响

随着肥料产业的发展,我国复合肥料的产量逐年增高,生产工艺也发生了很大变化。连续3年采用室内盆栽试验,在养分含量(15-15-15)相同条件下,研究不同工艺复合肥对小白菜产量和品质的影响。结果表明,不同工艺复合肥养分总量相同,而有效养分形态和含量存在显著差异(P＜0.05)。与不施肥处理相比,不同工艺复合肥处理的增产幅度达到48.49%～122.93%。AZF复合肥15-15-15S和团粒法复合肥15-15-15S处理有利于小白菜的植株生长,产量较高,但叶片蛋白质和游离氨基酸含量较低,硝酸盐含量较高,品质下降;树脂包膜复合肥18-9-18S和单质肥料处理降低了小白菜叶片硝酸盐的累积,根系活力和叶片叶绿素含量较高,但产量较低。通径分析表明,不同工艺复合肥有效养分含量对小白菜产量的直接通径系数大小为:NH4+-N(1.9855)＞有效K(0.8002)＞有效Ca(0.6871)＞pH值(-0.1196)＞硝铵比(-0.354 0);对硝酸盐含量的直接通径系数大小为:pH值(0.9298)＞有效S(0.2176)＞硝铵比(0.1461)。小白菜叶片硝酸盐含量与游离氨基酸含量和SPAD值呈显著负相关(P＜0.05)。总之,高塔法复合肥15-15-15S较有利于小白菜的高产、优质栽培,且提升土壤肥力。
