At present, our northern spring-summer planting of black moor is at the precipitating stage, and southern winter-spring planting of black mo ear is at the mid-earth, which is the critical period of production and quality formation. In response to current weather conditions and the characteristics of the production of black-mule farming, the national centre for agricultural technology promotion, in conjunction with the national system of technology for the eating of bacillus industry, the ministry of agriculture and rural development's vegetables expert group, has developed technical guidelines for the management of black-mule spring cultivation。
North spring - summer cultivation
(i) temperature management. On the basis of local temperature and change trends, bacterial entry and opening time nodes are determined, using either a shed facility or an open concentrated seedling model, to ensure that the temperature in the bacterium pack is contained within 15-25°c for the recovery of sprouts, underlying occurrence and full earbrow development, and to avoid deviation from the appropriate range as far as possible. Temperature control can be achieved by taking advantage of day and night temperature differences, and by using solar warming capacity to adjust the grass curtain (sunnet) cap to control temperature. An abnormally low temperature can reduce ventilation, increase cover, and use mycelium to grow to heat up; in abnormally high temperatures, water can be poured on the shed film or on the concentrated sprouts to reduce the temperature of the ear environment。
(ii) humidity management. During the recovery and base occurrence phase, mist water is sprayed into space and the relative humidity of the environment surrounding the control kit is 75-85 per cent; during the growth phase of the earbreeding, a small amount of water can be poured into the capsule to swell the earbrush and the relative humidity of the environment surrounding the bag is 85-100 per cent. Timely inspection to prevent the drying of buds due to low humidity, resulting in the recovery of mysis and poor foundation effects, resulting in “blind mouths”. In case of abnormal temperatures, water is stopped and ventilation is enhanced to reduce environmental humidity to less than 50% in order to avoid abnormal earring and reduce the risk of bacterial infections。
(iii) ventilation management. With the recovery of the mycelium, the underlying occurrence and the growth of the ear buds, the gradual increase in ventilation time and the amount of ventilation to the extent that the temperature and humidity of the environment are guaranteed, the concentration of co2 in the environment in which the fungus are controlled is not higher than 0. 2%. In the event of abnormally high temperatures and humidity, all cover is removed and complete ventilation is provided。
(iv) light management. Incentives of light can be observed during the primary onset phase, and ear bud development can be enhanced to full-day light。
Southern winter-spring cultivation
(i) enhanced mid-term management. As the temperature rises in the spring and rain weather draws closer, the separation of the bacterium (pack) bags will become more severe, with the breeding material having a high base of fungi on the surface and a reduced vitality of the black molybdenum. Use of a limited amount of low-temperature and low-raining weather is no longer subject to “dry-wet-over” management, and water is used as quickly as possible for long and long harvests. In the production of sheds, it is possible to cover the tectonic membranes in order to avoid the loss of ears and ears due to rain。
(ii) timely harvesting and drying. Close attention should be paid to weather changes and the early completion of black wood harvesting and drying may be desirable to prevent the deterioration of quality and production due to high temperatures and rain-fed weather. The drying process is accelerated by the use of drying sheds with rain-resistant film. When rainy weather is not easily dry, it may be mixed with dry wood ears to reduce water content. When machine drying, dry hot wind temperature cannot exceed 60°c。
