| Abstract: |
| 【Objective】Shuidong mustard originates from Shuidong Peng village, Dianbai District, Maoming, Guangdong Province. It is a national geographical indication product in China. Zifei mustard (Purple leaf mustard, PL) is a new variety of high anthocyanin mustard bred by crossing Shuidong mustard in Shaoguan University in 2020, and its fertilization technology needs to be further studied. Organic fertilizer replacing part of chemical fertilizer is considered to be a more effective fertilization measure for soil improvement and crop yield and quality. It is of great significance to guide the scientific production of mustard to study the effects of organic fertilizer replacing part of chemical fertilizer on soil properties, yield and quality of mustard. 【Method】In this study, the Ganoderma lucidum residue compost was used as the test organic fertilizer, the green leaf Shuidong mustard (GL) and Zifei mustard (PL) were used as the test crops for pot experiment. With single application of chemical fertilizer (conventional fertilization) as control (CK), three treatments of low, medium and high mushroom residue compost replacing part of chemical fertilizer were set: T1, T2 and T3, the indexes of soil physical clay content (PC, <0.01 mm particle content), pH, SOM, AN, AP, AK, H, FW, RL, Chl, Ant, SS and Vc content of mustard after harvest were measured, and the differences of soil physical and chemical indexes and yield and quality of mustard under different treatments were analyzed. 【Result】The results showed that, with the increase of the amount of mushroom residue compost, besides pH and PC content (<0.01 mm particle content),other 13 indexes increased (T1 < T2 < T3). The SOM, RL, SS and Vc content of T1, T2 and T3 were better than CK (CK < T1 < T2 < T3), the contents of soil AP, AK, FW, Chl and Ant of mustard were only T3 better than CK (T3 > CK ≥ T2 > T1), and the AN of CK was better than T1, T2 and T3 (CK > T3 > T2 > T1), and the PH of T3 and CK were equivalent, and both were higher than T2 and T1 (T3, CK > T2 > T1). Compared with CK, the SOM, AP and AK content of GL / PL in T3 increased by 13.24% / 14.28%, 6.74% / 6.06% and 6.43% / 6.04%, AN decreased by 0.81% / 1.45%, FW, RL, the contents of Chl, SS and VC of leaf increased by 0.33% / 6.64%, 34.65% / 43.29%, 11.03% / 6.53%, 53.36% / 44.45% and 16.66% / 15.44% respectively, while the PH and Ant changed little. 【Conclusion】It shows that the mushroom residue compost replacing part of chemical fertilizer can improve the soil, and the production and quality of mustard. Moreover, the fertilizer effect of T3 is the best. |
