Dipped winter dates are one of the most popular fruits in the market, but consumers can only taste one or two around the Mid-Autumn Festival. In order to break the seasonal restrictions on the dipping of winter dates, there have been new attempts in Caojiamiao Village and the Institute of Jujube Research in Xiawa Town, Zhuanhua recently. On April 9th, Binzhou City held the third theme interview activity of "Juli 83 Project, Entering the Project Site", walking into the origin of winter jujube and exploring the upgrading road of the winter jujube industry.
At present, most of the open-air winter jujube trees have not yet sprouted, but it is a different scene in the winter warm greenhouse demonstration base in Caojiamiao Village, Xiawa Town. The lush foliage is full of life in the greenhouse. Jujube farmer Chen Yuanhong told reporters that this is due to the application of winter warm greenhouses, through refined management, so that winter jujube trees germinate in advance, results, the winter jujube market time is advanced. At present, the winter dates in the shed have sprouted on February 5 this year and are expected to be listed at the end of July.
It is understood that the management of winter warm greenhouses is mainly reflected in the control of temperature and humidity. In winter, the temperature in the shed is raised by the electric spoke heating equipment in the greenhouse, and the temperature in the shed is kept constant by laying mulch film. During the winter jujube fruiting period, special attention should be paid to controlling the temperature in the shed, the temperature should be controlled at 13 °C -35 °C, and the temperature difference between day and night should be controlled between 13 °C and 15 °C. The main role of the greenhouse is to keep the environment in the greenhouse in a suitable range for the germination and results of winter dates.
At the same time, the winter warm greenhouse abandons the watering method of flood irrigation in the open-air winter jujube garden, and adopts the method of fine water drip irrigation, which not only reduces the waste of water source, but also helps to control the humidity in the shed. In order to make up for the lack of light in the shed caused by continuous cloudy days, light lamps were also installed in the shed to increase the production of winter dates during the fruiting period of the winter jujube trees. The environment in the shed is relatively closed, which effectively reduces the entry of external pests, so it only needs to use less drugs to sterilize and eliminate insects. In addition, winter warm greenhouse fertilization is mainly based on organic fertilizers.
Similarly, in the Institute of Winter Jujube, there have been new attempts to cultivate winter jujube facilities, and quilt-type greenhouses and winter-warm greenhouses are under orderly construction. Yu Hongchang, director of the Institute of Winter Jujubes, told reporters that the winter dates grown in the quilt-type greenhouses can be listed in August, and the winter warm greenhouses are listed about a month earlier than the quilt-type greenhouses.
In addition to the early listing to meet the taste buds of consumers, in order to extend the time to market, a delayed maturity greenhouse is also being built in the research institute, and it is expected to be launched in November. Yu Hongchang introduced that through facility cultivation, it can be marketed in advance and delayed maturity. With the addition of 3 months of storage time, you can eat winter dates for about 10 months of the year.
