Embodiment 1

[0009] Embodiment 1, a kind of sylvestris sylvestris sylvestris species vernalization technology comprises the steps:

[0010] Step 1, at a temperature of 10°C, place the tree species in a ventilated place for 4 days, and spray water mist every 1 hour;

[0011] Step 2, place the tree species in the wooden box for 20 days, and put into the wooden box twice the river sand of the seed volume, carry out stratification and germination, ensure that the temperature in the wooden box is at 5 ° C, often stir and check;

[0012] Step 3. Place the wooden box in a cultivation room at about 16°C for about 10 days, and spray cold water on the surface of the wooden box;

[0013] Step 4, transfer the wooden box to a cultivation room at about 20°C, and observe once every 6 hours; when about 40% of the tree species cracks and the seed coat leaks out, the seeds can be sown;

[0014] Step 5, when the tree species in the step 4 only has a small area gap, and does not leak the seed coat, then the ...

Embodiment 2

[0015] Embodiment 2, a kind of sylvestris sylvestris sylvestris species vernalization technology, comprises the steps:

[0016] Before the germination, the trees were first soaked for 3 hours with 25°C of potassium permanganate solution, and then soaked for 24h with 23°C of clear water. , Disinfect and clean the seeds.

[0017] Step 1, at a temperature of 13°C, place the tree species in a ventilated place for 5 days, and spray water mist every 2 hours; make the tree species fully imbibition, soften the seed coat, and convert the material in the seed into a germ that can Absorbed substances, and use a tool to cut the seeds along the growth direction of the immature embryos for inspection, and observe the growth status of the immature embryos.

[0018] Step 2, the tree species is placed in the wooden box for 30 days, and put into the wooden box twice the river sand of the seed volume, carry out stratification and germination, ensure that the temperature in the wooden box is at ...

Abstract

The invention discloses a pinus sylvestris tree seed germination accelerating technique. The technique includes following steps: step 1, putting tree seeds at a ventilated place at temperature of 10-15 DEG C for 4-6 days, and spraying water mist once every other 1-2h; step 2, putting the tree seeds in a wooden box for 20-40 days, putting river sand with volume of two times that of the seeds in thewooden box for laminated stratification, and ensuring temperature in the wooden box to be at 3-5 DEG C; step 3, putting the wooden box in a cultivation chamber at about 16 DEG C for about 10 days, and spraying cool water on the surface of the wooden box; step 4, transferring the wooden box into a cultivation chamber at about 20-25 DEG C, and observing once every other 6h, wherein seeding can be performed after about 40% of the tree seeds crack and expose seed coats. At the moment, tree seed cells have stable water content, temperature inside the tree seed cells can be turned to low temperature, activity of enzyme inside the tree seed cells can be reduced correspondingly, metabolism of young embryo cells tends to be slow, but experiments show that embryos can accumulate more sufficient nutrition when temperature is controlled at about 5 DEG C.

Description

technical field [0001] The invention relates to the field of sylvestris pine planting, in particular to a technique for accelerating germination of sylvestris sylvestris pine species. Background technique [0002] Pinus sylvestris is a tree species in the family Pinaceae. It is a light-loving and deep-rooted tree species. It can adapt to ridges and sunny hillsides with less soil moisture, as well as drier sandy and gravel sandy soil areas. Mixed students. The developed root system of Pinus sylvestris can make it resistant to barrenness and drought, and has relatively strong cold resistance and wind resistance. During the growth process of Pinus sylvestris, its seedlings like light, the sprouts form relatively quickly, and the budding time is early, so the seedlings are not easy to be damaged by late frost during the growth process. Pinus sylvestris is the main fast-growing timber, protective greening, and excellent tree species for water and soil conservation. The materia...
