Management process and key points of morel fruiting after watering
1. Needle tip differentiation period
1: Is it necessary to build an arch shed?
The main purpose of building an arch after bud induction is to keep moisture and keep heat. If the moisture retention and airtightness of the greenhouse itself are good, you don't need to build a small arch shed. Such as semi-underground sheds, clay with good water retention, etc.
2: Use black mulch or white mulch?
It depends on the type and light transmission conditions of the shed. The shading rate of black mulch is about 70%. In addition to moisture retention, it can also play a cooling role. White mulch has good light transmittance, and the temperature rises quickly inside the film, and the temperature is relatively high. For greenhouses with strong light transmittance, good internal temperature maintenance, and need to play a cooling role, black mulch can be used, otherwise white mulch can be selected. However, it should be noted that after using black mulch, if the scattered light inside the film is too dark, it will significantly affect the number of mushroom buds.
3: Should the shed be kept hot and stuffy?
High temperature and stuffy shed is a common practice in the north to promote the differentiation of primordium into needle tip mushrooms after warm water inducing mushrooms. The essence is to raise the ground temperature and maintain the temperature. By rolling up the quilt to increase the light, the temperature of the greenhouse is raised to 20~28℃, and the temperature at night is maintained stable by raising the ground temperature and storing heat. No matter how high the temperature is, the key is to control the ground temperature and surface temperature, which cannot be too high. However, this method is not suitable for all situations. It is relatively more applicable to the larger the greenhouse space. The smaller the space, the more attention should be paid to prevent high temperature from burning the buds.
