Chinanews.com, Lanzhou, January 5th (Ma Aibin) The Spring Festival is approaching, and greenhouse melons and vegetables are popular in the New Year's market.
In Heishan Village, Chongxing Town, Minqin County, Wuwei, Gansu Province, "eating" organic fertilizers, "living" in a sun room, and "sleeping" on rope-bed watermelons, are waiting to be boxed and marketed.
At the beginning of January, in the high-standard solar greenhouse industrial park in Heishan Village, round watermelons grew in the "air" among the intertwined vines. The grower Chen Ailing was very busy in her watermelon shed, picking, packing, and weighing.
"Because of the time difference, the current sales and prices are relatively good. In addition to some purchasers placing orders in advance, it has also attracted many tourists from surrounding urban areas to come to experience picking." Chen Ailing said happily.
Minqin County belongs to the temperate continental arid climate zone. It is surrounded by Tengger and Badain Jaran deserts on the east, west and north sides. The continental desert climate has obvious characteristics, with long sunshine hours and large temperature differences between day and night. It is a production area of high-quality agricultural products.
In recent years, Chongxing Town has taken advantage of its unique climate advantages and land resources to expand the agricultural development space of the town through land transfer and rural industrial structure adjustment, develop the greenhouse watermelon planting industry, and guide traditional agriculture to high-efficiency agriculture, characteristic agriculture, and tourism. Industrial transformation and upgrading, unlocking the "password of revitalization" in rural areas, promoting agricultural efficiency and increasing farmers' income.
In the process of producing watermelons in greenhouses, Chongxing Town has made bold attempts to explore and practice high-tech technologies such as greenhouse seedling cultivation, pumpkin grafting, hanging vine cultivation, and bumble bee pollination. "Aerial" growth results.
"'Watermelon in the air' is the watermelon hanging from the vine in the greenhouse. It uses techniques such as 'hanging' and 'grafting' to pull the watermelon from the ground to the vine." Xiang Jiangyuan, Secretary of the Party Branch of Heishan Village, said that the planting of hanging vines has achieved three-dimensional Cultivation improves the land utilization rate, makes the watermelon evenly irradiated by the sun on all sides, avoids contact with the ground and gets sick, and has a good appearance and taste.

In addition to the innovation of cultivation technology, Chongxing Town also screened and compared a number of new watermelon varieties, and carried out integrated demonstrations of mechanized production technology in management links such as environmental regulation and plant protection equipment. The water-saving technology of "integration of water and fertilizer under mulch drip irrigation" applies thick base fertilizer, light application of seedling fertilizer, skillful application of vine fertilizer, and heavy application of fruit fertilizer, so that watermelon can be 'full and strong', green, organic and safe.
At the same time, through the implementation of facility soil restoration and green pest control technology, the drought and disease resistance of crops can be improved, so that the root system of watermelon will be deeper, the quality will be higher, and the yield will be more abundant.
At present, more than 400 mu of melon crops are planted in Chongxing Town, and the sales revenue has reached 3.6 million yuan.
“Next year’s ‘Watermelon in the Air’ will increase the number of trial varieties, and consider interplanting watermelons with different ‘skin colors’ such as green, yellow, and white to form a very attractive tourism resource and make the ‘high-value’ industry circle fans everywhere. Tourists will help revitalize the countryside." Xiang Jiangyuan said.
