Problems solved by technology

However, both experimental materials and scientific and technical personnel need to go to the Hainan Southern Propagation Base to complete it. The resulting cost of rice southern propagation and multigenerational reproduction is relatively high, which is unaffordable for ordinary scientific and technological personnel.

Embodiment 1

[0040] The off-season rice breeding box is composed of a frame body 12, a heating system and an integrated system of water, fertilizer and medicine, and is characterized in that: figure 1 , figure 2 , image 3 As shown, the frame body 12 is a cuboid structure with a height of 1.35m to 1.45m, unlimited length and width, and the front, left, right, back, and top surfaces are closed with PC solar panels; The PC sunshine board is a transparent anti-drip greenhouse special board with a double-layer hollow structure; the frame body 12 is placed on the concrete floor in the direction of sitting north and south, and it is placed 4-5° west of the geographical central axis, which is conducive to extending the light time, and use sealant to seal the gap between the frame body 12 and the concrete floor; as figure 1 Shown, utilize the PC sunshine board of frame body 12 fronts to be set as 3 sliding doors 6, and sliding door 6 is equipped with handle 16, is used for the access and breedi...

Embodiment 2

[0048] A kind of off-season breeding method for rice, adopting off-season breeding box breeding for rice, the place of breeding is in Yangxian County, Hanzhong City, Shaanxi Province, the rice species used are inter-varietal hybrid offspring, and the breeding method includes the following steps:

[0049] (1) Seasonal breeding

[0050] (1) Breeding time and breeding temperature control

[0051] The breeding season is from April 11th to mid-September. The natural weather temperature (°C) in Yangxian County from April to mid-September is shown in Table 3. The natural temperature from mid-May to mid-September can meet the growth and development requirements of rice. , but the natural environment temperature is low from mid-April to early May, which is not conducive to the growth of rice. In Table 3: No. 1 is the sowing to emergence stage, No. 2 is the seedling stage, No. 3 is the seedling stage to the early tillering stage, No. 4 ~ No. 16 is the tillering stage to mature stage, a...

Abstract

The invention belongs to the technical field of agriculture, in particular to an anti-season generation-adding breeding box for rice, which consists of a frame-shaped shelf body, a heating system anda water, fertilizer and pesticide integrated system, the anti-season generation-adding breeding box for rice features that the frame-shaped shelf body is cuboid in shape; the heating system consists of a temperature control box, a power wire, a heating wire and a temperature probe; the water, fertilizer and pesticide integrated system consists of a sprinkler head, a water delivery pipe, a water pump and a liquid medicine box; the breeding box is placed in a north to south direction, and is arranged by 4-5 degrees to the west of the geographic central axis. The breeding box is simple in structure and convenient to use, and is used for completing two-generation rice breeding in one year, so that the technical problem of generation-adding breeding in one-season rice planting area is solved, and the natural weather environmental hazards are reduced or overcome, the anti-season generation-adding breeding box is used not only for rice breeding, but also for other breeding plants in need of generation-adding propagation with wide application range.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an off-season breeding box for rice. Background technique [0002] During the growth and development of rice, a certain amount of accumulated temperature is required. For the northern regions where rice is grown in one season, only one generation can be bred a year due to the limitation of accumulated temperature. To cultivate a new variety, it takes 9 to 12 hours from the selection of parents to crossing and selection to passing the examination and approval. Generation, that is, it takes 9 to 12 years, the breeding cycle is long, the work is complicated, and the cost is high. Therefore, scientific and technological workers adopt the method of southern multiplication and multigeneration, that is, in the Hainan area that is suitable for rice growth all year round, two generations of rice can be propagated in one year. This can shorten the rice breeding cycle and speed up th...
