During the Spring Festival holiday, there are still many people who are still busy, including the seedling growers in Dongtai City, Jiangsu Province, the "hometown of watermelons", with the help of modern agricultural technology, even in the cold winter, the watermelon seedlings here still have not stopped. And this also brings them good economic benefits.
At present, although it is a cold day, the smart greenhouse of the seedling base in Dongtai City, Jiangsu Province, is warm and melting, full of greenery. Melon farmers are skillfully marrying watermelon seedlings.
Liu Guorong, head of a seedling base in Dongtai City, Jiangsu Province: In the past, it was greatly affected by the cooling cold wave, and the production of watermelon seedlings could not be guaranteed, but after the electrified intelligent constant temperature cultivation, the temperature, humidity, environment and other aspects were accurately controlled, and now it can be cultivated throughout the year.
This special insulating resistance wire is laid in the soil, which can convert electrical energy into heat energy, just like the floor heating installed at home, the temperature rises smoothly and uniformly, which is very conducive to the growth and development of watermelon seedlings, and the seedling rate can also reach 95% in winter.
Zhou Aifeng, an agricultural technician at a seedling base in Dongtai City, Jiangsu Province: The temperature in the shed can be maintained at about 20 ° C even at night. The traditional heating method, the constant temperature effect is poor, the air pollution is heavy, and the survival rate of melon seedlings is only about 70%.
The extension of the production cycle and the increase in the emergence rate have doubled the number of seedlings in these greenhouses compared with last year, calculated at the current price of 1.3 yuan per plant. Only one greenhouse can bring nearly one million yuan in output value. This mode of production is also adopted by more and more growers.
The improvement of the quality of seedlings has also directly led to the local watermelon planting, and the current watermelon planting area in Dongtai has expanded to 300,000 mu, with an annual output of one million tons of watermelon, a total output value of more than 3 billion yuan, and an average income of more than 10,000 yuan per mu.
