What about snails eating vegetable seedlings?

1, sprinkle plant ash at night and spray plant ash water on the leaves of vegetables, which can play a role in preventing and controlling existing snails; Pouring plant ash water into the soil can kill snail eggs (hydroponics is unnecessary). Besides, plant ash is a good potash fertilizer.

2. When the area where quicklime is sprinkled is small, sprinkle some lime powder around the roots of vegetables or vegetable gardens to let snails come out for food at night. When they pass by, they will be stained with lime, and they will be burned to death or dehydrated by the generated high temperature. When the area is large, spread a quicklime belt with a width of about 10 cm on the ditch and the ground, and use 5 ~ 7.5 kilograms of quicklime per mu to kill snails crossing the quicklime belt.

3, vegetable leaves or melon skin or fried wheat bran to trap and kill at night, vegetable leaves and melon skin can be combined with some fried wheat bran, put the vegetables aside, uncover the vegetable leaves the next morning and kill the trapped snails.

4. Snail catching by hand is slow and easy to identify. Especially in hydroponics, there are few places where snails can hide, especially in greenhouses. It's easy to catch the snail's life habit. Soil culture is a little troublesome. Before sunset, you can pile leaves, weeds and vegetable leaves in the field, and put them every 3 ~ 5 meters 1 pile. Before dawn, we should uncover the haystack and make a centralized arrest.

Live a regular life

Oncomelania hupensis overwinters in vegetable fields, green manure fields, roots of crops or under rocks of haystacks, gaps in soil, etc. From April to May of the following year, adults began to mate and lay eggs, endangering crops. In summer, when they encounter bad weather such as high temperature and drought, they hide and often secrete mucus to form a wax film to seal their mouths, so they can't eat for the time being.

After the dry season, the activity resumed, which continued to harm autumn sowing crops and eventually turned into overwintering state. So snails have two peaks in a year, one in April-June in spring and the second in August-September.

Snails lie down during the day and come out at night. Generally, they start feeding after 6 pm, and the feeding peak is 8 ~ 1 1. Snails like a cool and humid environment, hiding in wet places such as the back of leaves and soil cracks during the day.
