February 4 is the beginning of spring.
The beginning of spring contains hope and warmth.
The prelude to spring is about to begin.
As the saying goes, "at the end of the first year of spring, farming is calculated early".
Influenced by the northern climate.
At present, it is not suitable for outdoor planting.
But. Haidian District Plant Tissue Culture Technology Laboratory.
referred to as the district tissue culture room) in the greenhouse.
Spring sowing breeding is in full swing.
As soon as you walk into the greenhouse.
The reporter was fascinated by what he saw.
A furrow filled with seedling substrate is a hole tray.
Neatly placed in the greenhouse.
There is a clear division of staff.
Some dot seeds in the tray.
Some cover the substrate on the burrow disc after sowing.
Some are buckling the mulch, and the sowing work is being carried out in an orderly manner.
A staff member who was lighting seeds told reporters: "We are working here, not only to sow seeds, but also to sow hope." Every seed carries our expectation of a bumper harvest. Although it was hard work, I was filled with a sense of satisfaction and accomplishment when I saw the new varieties I had cultivated myself being widely promoted. ”
According to Hui Zhiming, a scientific and technological staff member of the district tissue culture room, a total of more than 900 peppers and more than 500 eggplants were sown this time, mainly including flower culture strains, hybrid combinations, inbred lines and introduction materials. "Generally, seedlings begin to emerge about 7 days after sowing, and after the emergence of seedlings, it is necessary to strengthen temperature, humidity management and pest control, the temperature is controlled at 22 32 during the day, the temperature is controlled at 15 20 at night, and the relative humidity is controlled at 50% 60%. The seedling period of pepper and eggplant is about 60 days, and the greenhouse can be planted by the end of March, and various breeding materials are observed and screened in early June. Hui Zhiming said.
The district tissue culture room has successively bred more than 30 new varieties of pepper and eggplant with excellent comprehensive traits and meet the needs of production and consumption, of which 20 varieties have passed the examination or identification, and 24 varieties have obtained the registration certificate of non-major crop varieties of the Ministry of Agriculture and Rural Affairs. The new varieties have been popularized and applied in 236 cities and 592 districts and counties across the country, with a cumulative promotion area of 4.5 million mu and social and economic benefits of more than 7 billion yuan. The completed scientific and technological achievements won the second prize of the National Science and Technology Progress Award, and the Beijing Science and Technology Progress Award.
There are 17 awards at or above the municipal level, such as the first, second and third prizes, the first prize of Beijing Spark Science and Technology, the first and second prizes of Beijing Agricultural Technology Promotion, and the Beijing Academic Achievement Award. It has obtained 10 national invention patents, including 4 national invention patents for the core technology of nightshade fruit vegetables, and has always been at the international advanced and domestic leading level.
Serving Haidian's agricultural production has always been an important function of the district tissue culture room. The person in charge of the district tissue culture room said that in the next step, the district tissue culture room will continue to give full play to its advantages in biological breeding technology, strengthen close cooperation with various vegetable planting parks in Haidian District, select and promote the application of more new varieties of peppers and eggplants suitable for Haidian planting, and help the high-quality development of Haidian vegetable industry.
Plant a grain of millet in spring and harvest 10,000 seeds in autumn. In the greenhouse of the district tissue culture room, this busy and orderly work scene not only shows the hard work of agricultural science and technology personnel, but also indicates a bright future for the high-quality development of Haidian vegetable industry.
Busy is the hope of spring.
It is the joy of reaping that is sown.
Seeds sown by farmers.
Stay until harvest time.
It will become a bunch of abundant fruits.
