Bacillus subtilis is a microbial agent widely used in the planting of vegetables, fruit trees and field crops, which has a good effect on improving the disease resistance of vegetables and promoting growth. But many people don't know how to use it, so let's introduce the specific use method and dosage of Bacillus subtilis.
Method 1: Bacillus subtilis root irrigation
After transplanting vegetable seedlings, Bacillus subtilis agent is diluted 500-1000 times and mixed with water.
It is applied directly to the roots of vegetables to promote plant growth and prevent root diseases.
Method 2: Bacillus subtilis seed dressing
According to the recommended dosage (such as 500-800 grams per mu), mix the fungicide with the seeds evenly.
Note that if the amount of seeds per mu exceeds 10 kg, the amount of fungicide needs to be increased appropriately.
Method 3: Sprinkle
It can be used alone or mixed with fine soil, farm fertilizer, chemical fertilizer, etc. Especially in recent years, mineral source yellow has been used.
Potassium humnitate and Bacillus subtilis are compounded in particular, and the effect of 1+1 greater than 2 is realized. After application, plough in time.
soil, making sure that the microbial agent is well mixed with the soil.
Method 4: Flush
The microbial agent is mixed with water to form the mother liquor, and then applied with water.
The dosage per mu is usually 1000-2000 grams.
Usage Reference:
Field crops: The dosage per mu is usually 1000 grams.
Cash crops: 1000-3000 grams per mu.
Fruit trees: 20-50 grams per plant.
Seedlings: sprinkle 10-15 grams of soil per square meter into the seedbed.
Notes:
When using Bacillus subtilis microbial agents, they should be avoided mixed with alkaline pesticides to prevent reducing the effect of microbial agents.
It is advisable to spray in the morning or evening when the temperature is low and avoid periods of high temperatures.
