How to use microbial inoculum? Use of microbial agents and matters needing attention

Because of the wide distribution of orchards and the large number of fruit trees in China, a lot of fertilizers are needed. In recent years, with the development of agricultural biotechnology, microbial agents have been gradually used by fruit farmers. Microbial inoculum has a wide application range, will not cause any environmental pollution, and can obviously improve the structure and physical and chemical properties of orchard soil, loosen soil and improve soil fertility after use; Promote the growth and development of fruit trees and improve their quality; Enhance the ability of fruit trees to resist pests and diseases; Improve the root environment of fruit trees.

Microbial agents mainly rely on active bacteria, so the application method is different from common fertilizers such as chemical fertilizers. Kobayashi will tell you the usage and precautions of microbial inoculum, and you can learn it.

First, seed dressing and seed soaking

Seed dressing: dilute the microbial inoculum with a small amount of water, put the seeds into it and mix them evenly, then put them in the shade to dry.

Soak the seeds, dilute the microbial inoculum with a small amount of water, soak the seeds for about 6- 12 hours, and sow.

Seed dressing and soaking can be used for seedling raising of fruit tree rootstocks.

Second, soak and irrigate the roots

Dip the roots, dilute the microbial inoculum with a small amount of water, and immerse the roots of the seedlings cleaned by nutrient soil into the diluent to make them fully stained with the bacterial liquid.

Root irrigation is to cultivate the seedlings soaked in the roots, and then irrigate the roots with the remaining bacterial liquid for culture.

Third, base fertilizer

Base fertilizer can be applied together with farmyard manure, and the effect is better. Apply by burying near the roots.

The application depth of deep-rooted fruit trees should be 40-60 cm, and the application depth of shallow-rooted fruit trees should be 30-40 cm (the root growth depth of root fruit trees should be increased or decreased appropriately).

Generally, about 0.5- 1kg microbial inoculum is applied to a fruit tree (the dosage is appropriately increased or decreased according to the size of the fruit tree) and evenly sprinkled into the dug pit; After that, you can cover it with soil and water it.

Four, the application of microbial agents matters needing attention

When applying microbial preparations, the following points should be noted:

1. Avoid high temperature, drought or rainy days, which will affect the activity of bacteria.

2. It is forbidden to use it with herbicides, pesticides and fungicides, which will reduce the activity of bacteria and even directly kill beneficial bacteria.

3. Microbial fertilizer can not only be used as base fertilizer, but also as topdressing in fruit tree planting, and the effect is also great.
