The snail is heterozygous, has a fast growth rate and a long hazard. It mainly harms the leaves and seedlings of vegetables, especially the buds. It not only causes the holes and nicks of the leaves of the plants, but also often induces the infection of the bacteria to cause rotten dead seedlings, and even causes the seedbed to be destroyed, which seriously affects the improvement of vegetable quality and yield.
In recent years, due to neglect of prevention and control, some vegetable snails have occurred seriously, and there is a tendency to spread to orchards, field vegetables, and potatoes. It should be highly valued by farmers and friends. The following methods are commonly used. :
1. Agricultural control measures: Snails prefer a humid environment and have the habit of inhabiting and breeding, and frequent activities at night or in rainy days. Therefore, it is necessary to remove accumulated water in time after rain, strengthen cultivating and weeding, and destroy the habitat of snails.
2, artificial trapping and killing: in the evening or after rain, use leaves, leaves, fresh grass to make a trap, or use old sacks to put or use waste straw to pile up, trapped after spraying water. Focus on catching in the early morning of the next day, killing or feeding poultry with boiling water.
3, protective belt seedlings: 5 to 7.5 kilograms of quicklime per 667 square meters, in the ground side of the field to protect the belt, the seedling effect is very good.
4, bait trapping: freshly cut fresh leaves, potato chips, watermelon rind, etc., mixed with 80% trichlorfon WP 800-1000 times, or mixed with acetaldehyde effective ingredients 5% bran, corn The powder is used as a poison bait, and it is good to scatter in the field in the evening.
5, chemical control: with 98% copper sulfate 800 ~ 1000 times liquid, or with 1% saline, or with ammonia 800 times liquid, Daejeon can also use 50% parathion EC 1000 ~ 1500 times liquid spray control, both Can play a very good killing effect.
Light Steel Structure has been widely
applied in civilian facilities in the recent years. The structure uses cold
roll galvanized steel plates and has the features of: light weight, easy
installation, low price, recyclable, clean building site, etc. The elements are
manufactured and partially assembled in the factory and only installation is required on the work
site.
