In recent years, the melon planting area has gradually expanded, and the production mainly involves thick-skinned melons and thin-skinned melons. Thick-skinned melons are mainly planted in early spring greenhouses and planted in small quantities in autumn; thin-skinned melons are planted in open fields, mostly interplanted with cotton in summer. Thick-skinned muskmelon has high sugar content, good quality, and good taste, but the ripening period is too long. Only two candied melons can be harvested in one season. The quality of the second melon melon is obviously lower than that of the first melon, and it is not stored under high-temperature weather in summer. However, the thin-skinned muskmelon planted in the open field has low sugar content, general taste and poor commercial quality.
The Bureau of Agriculture of Caidian District, Wuhan City, Hubei Province has actively introduced melon varieties to carry out trials and demonstrations. Through spring and autumn planting, comprehensive quality, high yield, time to market, shelf life, resistance to low temperature and low light, etc. were measured to screen out thick-skin hybrids. Melon - topaz.
This species is very similar to the common gold melon, but the gold melon is a thin skin, and the top quality is a thick-skin hybrid melon, and the growth potential and leaf characteristics are similar to that of the melon. Plants have strong resistance to stress, easy to set fruit, and weigh more than 1 kg. Mature skin is golden, there are rich clear fragrance, crisp and sweet flesh, fruit resistant to storage and transportation.
The expressway has the characteristics of fast speed, large flow, fully enclosed, and full interchange; vehicles are required not to slow down and stop arbitrarily. Once the fog and haze weather occurs on the expressway, the visibility of the road will be reduced, which not only reduces the driver's visual recognition ability, but also causes the driver's mental fatigue, which is likely to cause judgment and operation errors, which will lead to a series of multiple vehicles rear-end serious traffic accidents. In response to fog accidents on expressways, the fog area safety monitoring system has received increasing attention. Among them, the roadside high-brightness fog lamps as the road contour indicator subsystem can effectively induce traffic flow in the fog and haze weather.
The "foggy anti-collision small artifacts" installed on both sides of the expressway are warned by the "yellow light guide, or red light to slow down" to remind the vehicle to slow down and pass the foggy road safely. Add flashing lights and oscillating markings on important bridges, tunnels, ramps and bends, add reflective strips to guide the tunnel walls along the line, install lighting facilities on the extra-large bridges, and upstream from the beginning of the Tuanwu section. A set of vehicle distance confirmation signs will be added at ~2 kilometers, yellow flashing lights will be added near the lower crossing of the toll station and the lower crossing of the service area, and warning slogans shall be set up.
