Abstract:

In order to study the application effects of bio organic fertilizer and specific water-soluble fertilizer on Vitis vinifera L., a 2-year (2020 and 2021) continuous plot experiment was conducted, with conventional fertilization as the control (FP treatment). The effects of bio organic fertilizer (SR treatment) and bio organic fertilizer+specific water-soluble fertilizer (ISSM treatment) on grape yield and soil nutrient content were studied. The results showed that the yield of ISSM treatment was significantly higher than other treatments for 2 consecutive years (P<0.05), with values of 11 985 and 10 939 kg·hm-2, respectively. Compared with FP, ISSM treatment had the most significant increase in yield, with increases of 2 550 and 2 528 kg·hm-2, respectively, and the yield increase rate reached 27.03% and 30.05%. In terms of soil nutrient content in vineyards, ISSM treatment has a significant effect on increasing soil pH, available phosphorus content, available potassium content, and exchangeable calcium and magnesium content, but its effect on increasing soil total nitrogen content and organic matter content is not significant. In terms of the correlation between soil nutrient content and yield of Vitis vinifera L., there are significant or extremely significant differences between the 2 a yield of Vitis vinifera L. and the soil available potassium content or exchangeable calcium content. Overall analysis shows that the combination of bio organic fertilizer and specialized water-soluble fertilizer (ISSM treatment) has the best effect.

Key words: bio organic fertilizer, Vitis vinifera L., yield, soil nitrogen content
