1, morphological characteristics
Hair germs Comatrichapulchell (C. Bab) Rost, also known as hairdressing network. Its morphological characteristics are cystic, sometimes dense, stalked, ovate to cylindrical, slightly apical, dark brown or rust-colored, full height 0.7-1.5(-3mm); stalk black, generally shorter than cysts, Rarely reach half of full height; capsule basement membrane, discoid solitary, or conglomerate; capsule axis straight, upward tapering, proximal to capsular; spore dense, curved, dark brown, thicker main branch, Branches taper, joints more, free at the end less, spores spherical, brown when the heap, diameter 6.5--8cm.
2, harm symptoms
This sticky fungus occurs on the exposed soil of the bamboo surface or the straw covering the surface of the bamboo, spreading rapidly. The culture materials in bamboo rafts damaged by slime mold become moist and rot. The growth of mycelia is inhibited or gradually disappears. There is a large amount of bacteria and nematodes in the culture materials, no bamboo shoots grow; the bamboo buds are damaged by water stains and mildew. .
3, the incidence of disease analysis
3.1 High-temperature and high-humidity environmental conditions Mucilages are suitable for growth in areas with rich organic matter and moist environments. Especially under the conditions of high temperature and high humidity, it is most conducive to the germination and growth of myxomycotina, and the vegetative colonies will spread quickly. The culturable body can expand to 20cm in one day and can cover large boring mills within a few days.
3.2 Culture materials Infection Bacteria Myxomycetes are omnivorous organisms. Bacteria, organic matter, mycelia fragments and spores of edible fungi are all nutrient sources of Myxomycetes. In particular, bacteria is a good food for slime bacteria. If the bamboo culture material or bamboo buds are infected by bacteria, mucilage is prone to occur.
3.3 soil or water, air with slime.
4, prevention and control technology
The prevention and control of Myxomycetes is the same as the control of crop diseases, and the principle of "prevention as the mainstay and comprehensive prevention and control" should be adopted.
4.1 Use of high-quality strains that are free from pollution and strong in life. Before the bacteria species are used, they must be checked carefully. They should not be used for cotton strains, odors, or strains that are too dry, too wet, or too old.
4.2 Pay attention to the selection of the plots and turn over and sterilize them in advance. To select sunny, ventilated, fertile soil and easy-drainage plots as bamboo raft cultivation sites, it is necessary to remove the straw roots from the plots and turn them into plows 20-30 days in advance. It is necessary to clear the gully drain around Putian. The ditch should be clear and wide and dig deep to prevent rainwater from accumulating. In the 7-10 days prior to cultivation, 1:500 sprays of dichlorvos and carbendazim and 25 kg of lime per 666 m2 were used to kill insects and sterilize them; Sterilization.
