Embodiment 1
[0020] First, the respective fermentation cultures to obtain cell concentrations of 18.2 billion / ml Bacillus natto, 15.7 billion / ml Lactobacillus, 10.3 billion / ml Rhodopseudomonas palustris and 2.8 billion / ml Saccharomyces cerevisiae, such as attached figure 1 As shown, the cell concentration of 18.2 billion / ml Bacillus natto 100ml, 15.7 billion / ml Lactobacillus 100ml, 10.3 billion / ml Rhodopseudomonas palustris 100ml and 2.8 billion / ml Saccharomyces cerevisiae 100m were mixed, and then Adding 0.5‰ of Abamectin, the total cell concentration obtained is 11.75 billion / ml, and the content of Abamectin is 0.5‰ of micro-ecological foliar fertilizer, as attached figure 2 shown. In the experimental group, the micro-ecological foliar fertilizer composed of 4 kinds of probiotics and 0.5‰ abamectin was diluted 100 times with water, and sprayed evenly on the leaves of rapeseed once every 7 days. , and the control group was sprayed with the same dose of water. After 40 days of growth, ...
Embodiment 2
[0022] Firstly, the cell concentrations of Bacillus natto, 15.7 billion / ml, 10.2 billion / ml Rhodopseudomonas palustris and 2.5 billion / ml Saccharomyces cerevisiae were obtained by fermentation respectively. , mixed according to the proportions of 15%, 15%, 45% and 25% respectively accounting for the total volume percentage, and then added 0.2‰ of abamectin to obtain a total cell concentration of 10.23 billion / ml, and the abamectin content 0.2‰ micro-ecological foliar fertilizer.
Embodiment 3
[0024] Firstly, the cell concentrations of Bacillus natto 19 billion / ml, Lactobacillus 16.3 billion / ml, Rhodopseudomonas palustris 10.5 billion / ml and Saccharomyces cerevisiae 2.7 billion / ml were obtained by fermentation respectively , mixed according to the proportions of 25%, 25%, 35% and 15% of the total volume percentage respectively, and then added 1.5‰ of abamectin to obtain a total cell concentration of 12.91 billion / ml, and the abamectin content 1.5‰ micro-ecological foliar fertilizer.
