The invention discloses a method for breeding alpinia oxyphylla seedlings under rubber trees. According to the method, the alpinia oxyphylla seedlings are bred among rubber tree rows in a rubber forest land with the gradient ranging from 0 degree to 15 degrees, wherein the plant spacing between every two rubber trees is 2-3 m, the row spacing is 6-8 m, the tree age is 10 years and above, the shading degree under the rubber trees is appropriately 70-90%, the plant and row spacing of the rubber trees is large, the general plantation density is that the plant and row spacing is 3m * 7m, the land utilization rate is low, if only the rubber trees are planted, water and soil loss is severe, soil fertility is lowered, and the ecological environment is prone to damage; weeds grow easily if only the rubber trees are planted, and management cost is high. According to the method, resource use efficiency of a rubber tree plantation is give full play, comprehensive benefits of the rubber tree plantation are increased, the alpinia oxyphylla seedlings are bred under the grown rubber trees, the land utilization rate of the rubber forest land can be raised, growth of weeds is inhibited, cost of breeding the alpinia oxyphylla seedlings can be lowered, economic benefits are increased, and the method is an effective measure for comprehensively upgrading the rubber and alpinia oxyphylla seedling breeding industries.

The invention discloses a method for cultivating and planting purple yams with high yield, and belongs to the field of a purple yam cultivating technology. The method comprises the following steps of (1) preprocessing and seeding of seed yams; (2) management of purple yam seedlings; (3) cottage and cultivation of purple yam seedlings; (4) filed growing management of purple yams; (5) harvesting of purple yams. According to the method provided by the invention, the purple yams are planted by tuber seeding and planting, therefore, the seed yams can sprout and emerge as soon as possible; by adopting a seedling arrangement way that the tips of the seed yams are upward and the longitudinal sections are obliquely downward, the germination rate can be improved by about 9.7% and the emergence rate of the purple yams can be improved by about 7.8%; in the process of growing the purple yam seedlings, a proper amount of fertilizers can be applied to provide the support of continuous and effective fertilizers and proper temperature and humidity to the growth of the seedlings, so as to ensure the survival rate and survival quality of the seedlings in the growth process of the purple yams; in addition, a cottage shed is ventilated and sprayed with water to realize moisturizing, therefore the excellent quality of the harvested purple yams at the later period can be ensured; in addition, the acre yield of the purple yams planted by the method provided by the invention is higher than that of the purple yams planted by a traditional method, and the benefit can be improved significantly.

The invention provides a constant temperature and humidity system and an alternate immersion testing machine including the system, the constant temperature and humidity system includes a water reservoir, a water pump, a heater, a humidifier, a temperature and humidity sensor, and a circulating water channel; The water channel is located on / in the side wall of the system, and the water in the reservoir is driven by the water pump to enter the circulating water channel for circulation; the heater is one or more, placed in the reservoir and / or the In the circulating water channel; there are one or more humidifiers, which are placed in the space formed inside the constant temperature and humidity system. The constant temperature and humidity system provided by the invention can realize precise control of temperature and humidity in the target operating space, and is especially suitable for the alternating immersion testing machine used for stress corrosion resistance testing.

The invention provides a switch cabinet temperature and humidity monitoring system. The switch cabinet temperature and humidity monitoring system comprises a cabinet, a first vertical plate, a secondvertical plate and a plurality of layers of diaphragm plates, wherein the first vertical plate and the second vertical plate are arranged on two sides inside the cabinet; the plurality of layers of diaphragm plates are arranged between the first vertical plate and the second vertical plate; a temperature and humidity monitoring mechanism is arranged on an inner side of the first vertical plate inan ascending-descending manner; air blowing mechanisms are arranged on the first vertical plate corresponding to each layer of diaphragm plate; air-releasing mechanisms are arranged on the second vertical plate corresponding to each layer of diaphragm plate; and the air blowing mechanisms are provided with dehumidifying mechanisms. Through adoption of the switch cabinet temperature and humidity monitoring system, the temperature and humidity in the switch cabinet can be monitored and controlled in order to keep proper temperature and humidity in the working environment of a switch. Meanwhile,a cooling mechanism is used for cooling each switch, so that a better cooling effect is achieved. Moreover, the overall mechanism is uncomplex, and the cost is very low.
