Successful trial planting of cantaloupe and other northern fruits Tianya melon and fruit smell floating in the north

Not long ago, another kind of northern fruit jujube was successfully introduced in Sanya. This not only adds a new variety to nearly ten species of northern fruits introduced in Sanya, but also adds a new bright spot to Sanya's "north and south" program. The "Northern Fruit" experiment of Taiwan businessmen and Academicians originated from the late 1980s in Sanya. Over the past 20 years, with the continuous efforts of a group of scientists and agricultural enterprises, a series of "northern fruits" and "northern flowers" such as dates, grapes, roses and lilies have settled in Sanya one after another, forming one new industrial chain after another. Cai Keqin, head of the planting and Market Information Section of Sanya Agricultural Bureau, has worked in the agricultural sector for nearly 30 years and is an important witness and participant in the development of modern agriculture in Sanya. He said that the "north and south planting" in Sanya began with melons. In 1988, Taiwan-funded Sanheli Agricultural Development Co., Ltd. successfully planted thin-skinned melon in Sanya. Then, a group of researchers, represented by Wu Mingzhu, academician of the Chinese Academy of Agricultural Sciences, successfully planted cantaloupe in Sanya and taught the technology to local villagers free of charge. Nearly ten kinds of "north fruit" successfully planted in the south began with muskmelon, and "north fruit and south seed" opened branches and scattered leaves in Sanya. Recently, a reporter from Hainan Daily saw from the jujube base of Sanya Haiyuan Industrial Co., Ltd. in Langmeng Tianyang, Yacheng City, that the jujube tree introduced by the company last year in cooperation with Professor Xia Shurang, a national agricultural consultant in Sanya, has been fruitful. At the end of last year, Haiyuan Company and Professor Xia Shurang signed an agreement to introduce "Guitai Series" jujube varieties. At the beginning of this year, 33000 jujube trees were planted in the demonstration seedling cultivation base of 100 mu in the south of Langmeng Tianyang Northern Red Jujube. The jujube trees planted for the first time in Sanya are expected to be on the market by the middle of this month. Xia Shurang said that the flowering and hanging fruit of jujube trees in Sanya shows that this kind of high-quality northern fruit has been successfully planted in the south, but it is still necessary to strengthen technical management, cultivate fresh jujube varieties with high yield, high quality, and stress resistance, and better popularize them. let the common people plant fresh jujube on the road to prosperity. The planting base of Haiyue Tropical Grape Cooperative in Yacheng has also been successful. Li Dawei, head of the cooperative, told reporters that the successful cultivation of grapes in Sanya has broken the old idea that it is not suitable to grow grapes in the tropics, and that Sanya has the advantage of being out of season. The reporter learned from the Sanya Municipal Bureau of Agriculture that there are nearly ten species of northern fruits, northern flowers, roses, strawberries and lilies that have been successfully planted in the south of Sanya. The ambitious industrial plan thick-skinned melon originated in northwest China, while thin-skinned melon is mainly in the northeast. Grapes and jujubes are all temperate crops, but they are widely popularized in Sanya at present, including 16000 mu of cantaloupe, 30, 000 mu of planting area and an annual output value of more than 400 million yuan. The thin-skinned muskmelon represented by "Qianlixiang" and "Honey World" has a planting area of about 1 / 3 of thick-skinned muskmelon, and its output value is more than 100 million yuan. The Sanya municipal government has seen the huge development of empty merchants in Beiguo. This year's government work report clearly pointed out that it is necessary to build a 100-mu fresh jujube base and a 50-mu out-of-season grape demonstration base within this year, and promote the development of facility agriculture and "north fruit and south planting" in Sanya. Sanya is ambitious to build the "North and South seed" into an industrial cluster with an output value of billions of yuan. In fact, a few years ago, Sanya officials consciously guided the planting of northern fruits. Since 2006, Sanya has made great efforts to promote the cultivation of cantaloupe in greenhouse, and the investment of financial subsidy has reached 150 million yuan, driving private investment of about 300 million yuan. The large-scale spending of the government has also promoted the "North and South seed" to make a qualitative leap. According to the Development Plan of Modern Agriculture with Tropical characteristics in Sanya City issued this year, by 2020, the area of melons and vegetables in the greenhouse represented by Hami melon will reach 50, 000 mu, and the planting area will exceed 100000 mu. Academician Wu Mingzhu said that growing cantaloupe at the facility is definitely a leap and direction. First of all, facility agriculture can save land. 1100 cantaloupes can be cultivated per mu, while only 500 or 600 can be cultivated in general cultivation. Secondly, the yield of facility agriculture is high, and the yield of cantaloupe per mu is about three times that of ordinary cultivation. At the same time, protected cultivation can advance and postpone the growth period, increase the planting time, and greatly improve the land utilization rate. She said that this is of great significance to make full use of China's very scarce tropical land resources.
