On the testing ground of Qingdao Sea-rice Research and Development Center, the 176 fl ourishing sea-rice plants are entering the milk-ripe stage in May. The quality rice will be planted experimentally for the fi rst time in the fi ve typical salinealkali areas in our country.

“If the sea-rice planting area could be expanded to 100 million mu,another 80 million people could be well fed.” With the effort of Yuan Longping,known as “father of hybrid rice”, and his team, Qingdao sea-rice reaped a good harvest last September. Several days ago, this technology succeeded in spreading out of Shandong to other countries, with Dubai as its fi rst stop.

When sea becomes land, Shandong agriculture, like a bird, will fl y farther and farther on the wings of technology.

When Seeds Fly on the Wings of Technology

With harvest at hand, Zhang Hui, a farmer in Houzhuang Village,Longyang Town, Tengzhou City, said happily while looking at the potato plants: “‘Xisen 6’ grows very well. Its yield is estimated to be 6-7 ton per mu,which is an unattainable goal for other breeds.”

For its high yield of 9 tons per mu, the new type of potato, which was developed after eleven years of experiments, has created a miracle in the world of potatoes, and is now going along the “One Belt and One Road” to help many other countries to participate in industrial potato improvement, something which has been applauded by 37 agricultural ambassadors to China.

For 20 years, Shandong finance has invested about 2 billion yuan into order to help push forward the finebreed engineering, which has become a distinctive characteristic of Shandong agriculture technology innovation construction.

“Jimai 22” has been the wheat variety with the largest planting area in China for 7 years on end. “Denghai Corn” series set the high-yield-corn record for China 7 times in succession,with a cumulative yield increase of more than 120 billion kilograms. The single-seed precision sowing technology of peanuts broke the actual-yieldper-unit record of China, and now 22 domestic peanut varieties are being planted experimentally in the cultivation of greenhouse vegetables, up to 1.4 billion seedlings can be cultivated a year in Shouguang alone and the production value of vegetable industry is over 20 billion yuan.

Ever since the implementation of fine-breed engineering, more than 35,000 germplasms of various organisms have been collected,introduced and preserved in Shandong and 2 348 new varieties have been successively bred. The main crops in Shandong have been upgraded three or four times and the contribution rate of fine breeds to the growth of agricultural production amounts to as high as 48%.

Science and Technology in the Agricultural Park

A s o n e o f t h e b e s t e d i b l e mushrooms, jade fungus has been the focus of the industry ever since its birth. “Jade fungus has a good market prospect, for it is better than black fungus in taste, nutrition, and economic benefits,” said Li Yu, an academician of Chinese Academy of Engineering and the honorary president of Shandong Kechuang Edible Mushroom Industry Technology Institute. The annual earnings of jade fungus in one greenhouse can be 80,000 to 120,000 yuan, 50% higher than that of ordinary black fungus.

As the only national edible mushroom-featured agricultural scitech park in China, Zoucheng National Agricultural Sci-Tech Park cooperates with many colleges and universities,and has turned the small mushrooms into a big industry that enjoys great popularity all over China by setting up the professional incubator for edible mushroom sci-tech enterprises and establishing Kechuang Edible Mushroom Industry Technology Institute. At present, in Zhoucheng there are over 50 industrialized edible mushroom enterprises and economic cooperation organizations, with over 20 famous high-quality varieties, including needle mushrooms, agaricus bisporus,chopped camellia and jade fungus, with an annual output value of 5 billion yuan.

“The Ministry of Science and Technology is presently promoting the construction of agricultural scitech park systems. Shandong has taken the first step in this aspect,” said Liu Weimin, head of the Department of Science and Technology. Shandong has developed a preliminary agricultural sci-tech park system of four-level linkage and echelon development and established a comprehensive agricultural technology service platform based on the “Internet Plus” of “cloud agricultural sci-tech park” to achieve an agricultural scie-tech innovation service system with provincial coverage and seamless connection and to develop another agricultural science and technology project with nationwide inf l uence.

High-Tech Opens up New “Routines”

“Because the seedlings of kelp growing in cold sea water are very sensitive to sunlight, the intensity of sunlight becomes one of the key influencing factors for the yield and quality of kelp.” For many years, Mr.Wu, a technician in Weihai Changqing Marine Technology Company, has kept using the traditional way to monitor the intensity of sunlight. However,with the application of an IOT kelp seedling growing solution system, all that Mr. Wu needs to do now is simply to turn on a computer or a smart phone to monitor the real-time daily change of sunlight intensity inside the workshop.
