Half of the seedlings are good, and the seedlings are good for seven points
At present, it is a critical period for rice seedlings
Wang Wenzhuang Town, Xiqing District, grabbed the agricultural time
Actively use machinery and equipment to raise seedlings
Effectively improve the quality and efficiency of seedling raising
For the year-round grain harvest, agricultural efficiency
Build a strong foundation
Walking into Tianlong Science and Technology Co., Ltd. (National Japonica Rice Center) in Wangwenzhuang Town, with the roar, the reporter saw in the seedling raising base that a tray containing a uniform thickness of the subsoil, cover soil and rice seed production seedling trays, from the seedling machine "spit out", and then, the rice farmers put it in the greenhouse to cover the film to promote germination.

We have sown more than 1,000 plates today, and it is estimated that there are 70~80 breeding materials, mainly to compare and display the high-generation breeding materials that we are now researching, and compare them with the main varieties "Jinyuan 89" and "Jinyujing 22" in Tianjin. Different materials have fragrance, rice quality, lodging resistance, disease resistance has a greater improvement, we began three years ago, the paternal and female parents were hybridized, after the hybridization, in the summer in Tianjin, in the winter to Hainan for a plus generation, the selection is now after the 7th generation and 8th generation, the hybrid varieties, I hope it has a higher yield, better rice quality, and is more suitable for planting spring rice in Tianjin.
At present, it is the critical period of rice seedling raising in small stations, and the staff of the National Japonica Rice Engineering Technology Research Center walked into the field to guide rice farmers to do relevant work.

●Director of the Laboratory of the National Japonica Rice Engineering Technology Research Center
Compared to other places, Tianjin's agricultural land area is very small, so we have been thinking about how to use limited land to improve the yield of varieties, such as what we are doing now is sowing work, in another ten or twenty days, the seeds will germinate, grow small seedlings, the laboratory can carry out the work, take the seedlings, and then carry out DNA extraction, test what genes are in the materials, such as disease resistance, good rice quality, fragrant genes and other genes. The development of science and technology has progressed, such as some processes of breeding, sowing, laboratory testing, the efficiency will be doubled, and then the quality of some starch content, protein content, sugar content, trace elements, are through these means of the laboratory to detect, determine, and screen, through these methods can obtain a more high-quality, more high-yield varieties to meet the needs of the people's table.
Over the years, Xiqing District has thoroughly implemented the spirit of General Secretary Xi Jinping's important instructions on the development of the seed industry, given full play to the talent and technical advantages of the National Japonica Rice Engineering Technology Research Center in breeding innovation, comprehensively increased independent innovation, solved the problem of breeding "stuck neck", and cultivated 111 new varieties of japonica rice with high yield, high quality, multi-resistance and wide adaptability, and the seeds developed by Xiqing have been developed in the northeast, north China, Huanghuai, southwest, northwest and other places in the mainland, covering more than 90% of the main rice producing areas. In particular, the planting area of high-quality varieties such as Tianlong excellent series and Jinte in Tianjin has been expanding, and the output of Xiaozhan rice has increased year by year.

●Deputy Director of the Achievement Transformation Division of the National Japonica Rice Engineering Technology Research Center
As a science and technology enterprise, the National Japonica Rice Engineering Technology Research Center has always focused on giving full play to its strengths, in terms of breeding, such as tissue culture, molecular breeding, including gene editing breeding...... In addition to these traditional breeding, there are also some new technologies attached to ensure the long-term and stable development of our small station rice, we have equipped a seed drying equipment for high-quality small station rice, and now there are more and more extreme weather, such as "Tianlong 619" With this set of equipment, after the seeds are mature, they can be harvested as soon as possible, then dried, and then stored in a seed to ensure the safety of our seeds, and the ultimate goal is to ensure that our rice bowls can be firmly held in their hands.
