The invention discloses an automatic control device for a plant growth environment. The automatic control device comprises a mixing chamber, a growth chamber and a clean air feeder which is connected with the mixing chamber; the bottom part of the mixing chamber is provided with two circulating fans; a first fan is used for eliminating exhaust gas in the mixing chamber and performing thermoregulating and conditioning on air in the mixing chamber; a second fan is used for air current circulation between the mixing chamber and the growth chamber; a plurality of cultivating racks are arranged in the growth chamber; each cultivating rack is divided into multiple layers; each layer is provided with drainage channel and a certain number of LED (light emitting diode) lamps; the drainage channels are connected with a water supply and drainage system and a nutrient solution supply system; growth environment parameter acquisition sensors are also arranged in the growth chamber; data acquired by each sensor are transmitted to a controller through the Internet of Things; various parameters of the plant growth environment are adjusted by the controller according to growth environment curves of plants in different periods; the controller is connected to a man-machine operation interface. According to the automatic control device disclosed by the invention, the seedling and growth cycles of crops can be greatly shortened, the land use rate is increased, and output per unit area is increased.

The present invention relates to an irrigation control device of Tieguanyin tea trees, characterized in that soil moisture sensors distributed in each irrigation division are used for detecting soil signals (analog quantity) in a real-time manner, the soil signals (analog quantity) are input into a control system after being converted into digital signals by an analog-to-digital converter, a control subsystem is an integrated control system which takes a single chip microcomputer as a core and starts or stops the control device in accordance with the preset control parameters to determine the irrigation time and amount; when the water potential of the soil decreases to minus 0.6 plus or minus 0.1MPa, a control signal for irrigation is output and the water irrigation amount is controlled to be 11.5-12.6m<3> per mu at one time. The control device provided by invention is particularly beneficial to cause the water irrigation to be more uniform and guarantee water need for growth of the tea trees during a dry season and microenvironment adjustment, and improves the quality and yield of tea leaves.

The invention discloses an efficient culture method of tree type honeysuckle. The efficient culture method comprises the following steps that: the varieties of the tree type honeysuckle suitable for the local climate are selected, loose sand soil convenient to drain and irrigate is selected, a planting garden is built, and deep cultivation, fine rake and ridge cultivation are carried out; the transplanting is carried out in autumn, base fertilizers are applied before the transplanting, the soil filling and the compact pedaling are carried out, root fixing water is watered, and film covering or soil covering is carried out in winter according to the air temperature conditions to prevent the freezing and preserve soil moisture; intertillage is irregularly carried out for weeding while watering after the germination in spring; leaf fertilization is carried out after flower picking in each time; slight shearing to a proper degree is carried out after flower picking in each time, and the tree form is trimmed after the tree body dormancy in winter until the early sprouting period in spring; harvesting is carried out in a bud period, and the baking is carried out in a baking room after the harvesting. Other commercial crops and other medical materials such as white paeony roots can be interplanted between ridges in the first three years. When the method provided by the invention is adopted, the tree type honeysuckle can enter the full-bloom period one year in advance, so the yield per mu in the full-bloom period reaches more than 150kg, and the flowering time is shortened by morethan 5 days in the whole year.

The invention discloses a method for curing tobacco leaves of the flue-cured tobacco variety RG11 matured under the condition of rainy and little sunshine. According to the baking characteristics of the tobacco leaves of the flue-cured tobacco variety RG11 under the condition of rainy and little sunshine, the whole process of tobacco leaf baking is carried out according to the temperature, humidity The tobacco leaf curing process is divided into three stages and seven steps, including the early yellowing stage, the middle yellowing stage, the late yellowing stage, the early color fixing stage, the late color fixing stage, the early gluten-drying stage, and the late gluten-drying stage. The quality of the finished tobacco leaves has been greatly improved; this curing method is highly operable, and can significantly improve the quality of the flue-cured tobacco variety RG11 and the proportion of high-quality tobacco, and reduce the rate of blue smoke; Variety RG11 has a unique style, which improves the planting income of flue-cured tobacco variety RG11.
