The methods of using agricultural microbial agents mainly include seed mixing, seed soaking, root dipping, root irrigation and base fertilizer application. The specific operations are as follows:
Seed mixing and seed soaking: Dilute the microbial agent with a small amount of clean water, put the seeds in it and mix evenly, and then place them in a cool place to dry. Seed soaking is to soak the seeds in the diluted agent for about 6-12 hours before sowing.
Root dipping and root irrigation: After cleaning the roots of the seedlings, immerse them in the diluted agent to ensure that the roots are fully contaminated with the bacterial solution.
Then cultivate and irrigate the roots with the remaining bacterial solution to promote the growth of the seedlings.
Base fertilizer application: Microbial agents can be mixed with farmyard manure and applied by burying them close to the roots.
The application depth for deep-rooted fruit trees is 40-60 cm, and for shallow-rooted fruit trees is 30-40 cm. Apply about 0.5-1 kg of fungicide to each fruit tree, spread it evenly in the dug hole, then cover it with soil and water it.
