In the vicinity of Heguan Town, Qingzhou City, Shandong Province, the most summer cultivars are planted with peppers and eggplants. Recently, when interviewed by reporters in the local area, vegetable farmers generally reported that the death of trees after planting was particularly serious. By visiting the reporter, it was learned that local vegetable farmers were often used to flooding the water when they planted vegetables, and then planted the vegetable seedlings directly in the planting ditch with water. This unscientific method of planting is the main cause of dead vegetables in local vegetables.
First of all, transplanting wounds easily cause wound outbreaks. Although it is watered and planted, the resistance of the transplanting with a hand is easy to make the roots appear wounds, creating an opportunity for germs, especially bacterial diseases. At the same time, flooding irrigation leads to large environmental and soil moisture in the greenhouse, which is conducive to the breeding and infestation of pathogens such as Phytophthora and Pythium, causing serious death of vegetables.
Second, flood irrigation caused high soil moisture and destroyed soil structure. Local habits of flood irrigation, resulting in particularly high soil moisture content, often lead to low oxygen content in the soil, low permeability, after planting is not conducive to the growth of vegetable roots. For example, if the peppers have accumulated water for 24 hours in the field, they may directly cause dead vegetables. In addition, the soil is muddy after flooding, and the soil aggregate structure is also particularly vulnerable to damage, making the soil permeability further reduced.
Therefore, transplanting planting is simple and convenient, but the root system after planting is contracted in the planting hole. This greatly delayed the time for the vegetable seedlings to slow seedlings, but also directly or indirectly caused the vegetables to kill the roots, rot and die.
Therefore, we recommend that vegetable growers can adopt the method of planting seedlings first, and then planting water after soiling to cover soil. This not only avoids the occurrence of the above problems, but also promotes the roots to lower and helps to form a strong root system, which lays a solid foundation for the later Zhuang. .
The mycelium is multicellular, has transverse septum, and is elongated by the growth of the apex, white, slender, woolly, gradually becoming filamentous. Mycelia are conjugated with each other to form a dense population, called mycelia. After mycelium saprophytic, the brown culture medium turned light brown. The fruiting body of a mushroom is like an open umbrella when it matures. It is composed of bacteria cover, stalk, fungus fold, fungus ring, pseudomycorrhiza and so on. Mushrooms are widely distributed throughout the earth and are most abundant in forest deciduous areas.
