Garlic has good resistance to continuous cropping.

Yongnian County is a major garlic planting county, but in recent years, due to the continuous planting of garlic, the physiological diseases are becoming more and more serious, coupled with the selective absorption of nutrients by garlic, which makes the phenomenon of insufficient nutrient supply prominent. showing dead seedlings, rotten roots, anthracnose and some late emergence of onion-shaped cylindrical leaves, which are not conducive to the normal bolting of garlic bolts. It not only increases the labor intensity of garlic farmers, but also reduces the yield of garlic. Changing the root environment of garlic is the key to increase garlic income, as follows:

Garlic mu with "Big Brother Nong" or "heavy stubble No. 1" biological bacterial fertilizer 2kg, flushing with water. After the application of biological bacterial fertilizer, a large number of beneficial bacteria in the soil multiply, form a protective layer around the garlic root system, effectively inhibit and kill the harmful bacteria, activate the ineffective nutrients in the soil, provide balanced nutrients of garlic, and make the roots good and strong.

Can also use "heavy stubble No. 1" 1 kg to water 5 kg per mu, soak for 4 hours for 6 hours, filter its clear liquid and mix it into 200 times liquid. Choose a sunny day without wind at 4: 6 p. M. to spray the crops so that the front and back of the leaves receive medicine evenly. The whole growth period was sprayed for 3 times with an interval of 7 to 10 days.

Attention should be paid to the prevention and control of underground pests to promote a bumper harvest. Select insecticides with high efficiency and low toxicity, such as "Jiubaojing" and "phoxim", with 1000 grams per mu, first pour the liquid into the container and add water to form the mother solution, and then flush with the water, so that the garlic root can receive medicine evenly, and the best control effect can be achieved.
