Ganoderma lucidum pest: White ants
White ants (CoptotermesformiosanusShiraki) are alias termites and house termites. Belonging to the class Insecta, Isoptera.
1. Morphology and habits there are three forms and different functional types of termites in each nest group. Large-winged ants (breeding ants), also known as flying ants, body length 7.5-8.5 mm, wing length 11 mm, head nearly round, brown, secretory hole is not obvious, antennae 21 nodes. Yellowish brown in chest and abdomen. The wings are gray-white and transparent, and the wings and leading edges are yellowish brown. The soldier ant is 5.5 mm long, the head is oval, yellow, and has obvious secretory holes. The upper jaw is brown, curved inward, and the inside is toothless. Antennae 14-15. Milky white chest and abdomen. Worker ant body length 4.5-6 mm, round head, no secretory hole, antennae 15-16 nodes, chest and abdomen milky white.
Termites are a kind of insects that live in nests and are social. In the south, big-winged ants are grouped on muggy, low-pressure evenings from May to June. Domestic termites like to be dark and humid, and they begin to go out in late spring and early summer, and the weather turns cool in autumn before gradually turning into the ant nest. In a cultivation field (room), ant nests are usually built on the ground, in mud walls, or on the ceiling. The nest can be divided into master and deputy, and the main nest is generally located near the water, where it is hidden, dry and rich in food. there are ant queens, queens, young ants, eggs and some workers and soldiers in the nest. auxiliary nests are places where workers and soldiers gather temporarily. There is a large ant path leading to the water source in the whole nest, and the ant path is connected between the main nest and the auxiliary nest.
two。 Harmful conditions eat Ganoderma lucidum section wood, feed along the wood grain, compete with Ganoderma lucidum for nourishment, seriously affect mycelium growth, section wood is eaten hollow, resulting in reduced production or no harvest.
3. Prevention and cure method
(1) the selection site should avoid the ant source, and tree stumps and weeds should be removed in and around the site.
(2) contact the local termite control institute and spray targeted drugs under their guidance according to the ant species and activities.
(3) around the cultivation field, pine wood and bagasse were buried and mixed with ant control drugs to trap and kill hidden ants.
(4) dig circular pits more than 50 cm deep and 40 cm wide around the site to prevent termites from invading.
(5) the termites were drowned or expelled by immersion and irrigation, and then poisoned with insecticides.

Production of licorice watermelon skin
Watermelon peel is rich in sugars, minerals, vitamins, with heat-clearing and detoxification, diuresis and other effects. The following introduces the production technology of licorice watermelon skin: shredding. Wash the fresh watermelon skin thoroughly with clean water, drain, remove the green clothes and red flesh, and cut into watermelon peels 0.2 cm wide and 6 cm long with a stainless steel knife. Pickled. First, mix sodium benzoate and salt, and the dosage is 0.1% and 10% of the weight of watermelon skin, respectively. Then marinate in the container in the order of one layer of watermelon peel and one layer of mixed salt, and the top layer of mixed salt is appropriate.

Expert introduction: the cultivation prospect of Gastrodia elata is promising.
According to Wang Kangcai, Associate Professor of traditional Chinese Medicine Research Office, School of Horticulture, Nanjing Agricultural University, Gastrodia elata is a valuable traditional Chinese medicine. Due to the large gap between supply and demand in the market, the cultivation of Gastrodia elata is particularly hot. According to the current market analysis, the price of dried Gastrodia elata is 150-200 yuan per kilogram, the profit is about 200 yuan per square meter, and the cultivation prospect of Gastrodia elata is promising. The growth of Gastrodia elata does not need light, but only suitable temperature and humidity. In most parts of the country, there are broad-leaved tree resources and slight acidity.
