Method for preventing and controlling Bradysia odoriphaga by utilizing offal of edible mushrooms

Abstract

The invention discloses a method for preventing and controlling Bradysia odoriphaga by utilizing offal of edible mushrooms and belongs to the field of vegetable planting. The method comprises the following specific steps: (1) digging leeks planting pools, wherein the direction and the length are determined according to different land parcels, the width is 1.1-1.3 meters, the depth is 0.1-0.3 meter, the interval among each pool is 0.5-0.7 meter, the distance from both sides of the pools to upright posts of a greenhouse is 0.05-0.2 meter, and the pools are provided with water drain ports communicated with a water storage pool; (2) hardening edges of the pools; (3) paving wire plastic films with the thickness of 9-12 in the pools and fixing the periphery of the wire plastic films on upper ports of the pools; (4) paving 13-18cm of the offal of the edible mushrooms in the pools; (5) planting leeks on the offal of the edible mushrooms; (6) placing nutrient solution in the planting pools every seven days; and (7) soaking for 24 hours and placing the nutrient solution in the water storage pool. According to the method, the growth humidity of the leeks is improved to enable the Bradysia odoriphaga to climb away from hosts by utilizing the characteristic that the Bradysia odoriphaga is sensitive to the humidity of the environment.

Description

technical field [0001] The invention relates to a method for planting leeks, in particular to a method for controlling leek maggots by using offcuts of edible fungi, and belongs to the field of vegetable planting. Background technique [0002] Leek root maggots are referred to as leek maggots for short, and the adult scientific name is Bradtua idiruogaga Yang et Zhang, also known as yellow feet (a small black mosquito), belonging to the family Diptera, and the larvae are called leek maggots. It often gathers in the underground of leeks to harm leeks, and eats roots, pseudostems and bulbs. After the leek is harmed, the young stems will rot, the stems and leaves above the ground will turn yellow, wilt and sag, and in severe cases, the whole mound of leeks will die, and the damage can occur many times in a year. [0003] The traditional control method is to use highly toxic pesticides: farmers spray phosphorus (alias 3911) or topdress carbofuran when leek maggots occur in leek...
