Embodiment 1
[0017] dry in the shade
[0018] From December 21st to 25th, 2010, the fresh masson pine cones were collected and transported back, stacked in a dry room on the cement floor and stored in the shade naturally. It is advisable for the cone skin to change from green to brownish green or brown without mold;
[0019] Remove the exocarp
[0020] On March 1, 2011, the exocarp scales were removed from the shade-dried cones of step with a knife, and the peeled thickness was 3mm;
[0021] drying
[0022] Spread out the exocarp cones in step and turn them in the sun once a day. After 3 days, the cones crack, and the seeds can be recovered in time depending on the cone cracking and weather conditions. Pay attention to rain and rodent protection.
[0023] After processing the cones that still cannot open, gather them together and repeat step .
Embodiment 2
[0025] dry in the shade
[0026] From December 21st to 25th, 2010, the fresh masson pine cones were collected and transported back, put into a ventilated snakeskin bag and stored in an open room in a natural shade.
[0027] Remove the exocarp
[0028] On May 1, 2011, the exocarp scales were removed from the shade-dried cones of step with a knife, and the peeled thickness was 4mm;
[0029] drying
[0030] Spread out the exocarp cones in step and turn them in the sun twice a day until the cones crack in 2 days.
[0031] Others are basically the same as in Example 1.
Embodiment 3
[0033] dry in the shade
[0034] From December 21st to 25th, 2010, the fresh masson pine cones were collected and transported back, put into a ventilated snakeskin bag and stored in an open room in a natural shade.
[0035] Remove the exocarp
[0036] On July 1, 2011, the exocarp scales were removed from the shade-dried cones of step with a knife, and the peeled thickness was 2mm;
[0037] drying
[0038] Turn it 3 times a day, and wait for the cones to crack within 2 days.
[0039] Others are basically the same as in Example 1.

Abstract
The invention discloses a Chinese red pine seed storing method which comprises the following steps: packaging fresh Chinese red pine cones in a ventilating snakeskin bag, keeping the snakeskin bag opened or stacking in a drying room and naturally drying in the shade; at the time of seeding and raising seedling, removing epicarp scale of the cones dried in the shade with a knife; spreading and sunning the cones with epicarp removed, overturning for 1-3 times every day, and recovering the seeds in time when the cones crack after 1-3 days. According to the invention, the Chinese red pine cones and seeds are simultaneously stored, and the seeds are taken out from the cones at the time of seeding and raising seedling; and because the stored seeds are in a sealed and stable environment wrapped by scales, the seed quality is ensured, and the germination ratio of the seeds reaches 85% after being stored for 270 days, is slightly superior to that of the seeds stored in 4 DEG C refrigerator, and obviously superior to that of seeds stored at room temperature. The method is low in cost, easy and simple to operate and high in seed germination ratio, effectively solves the problem that the basic-level production department has difficulty in seed storage, improves the seeding quality, and alleviates the situation that the demand on high-quality seeds of Chinese red pine exceeds supply.
Description
technical field [0001] The invention relates to plant seed storage, in particular to a storage method for masson pine seeds. Background technique [0002] Pinus massoniana (Pinus massoniana) is an important dual-purpose tree species for resin and wood in southern my country. It has a wide range of uses and high economic value. In addition to the two major uses of wood and pine resin, the whole tree of Masson pine can be used, and the pollen, needles and bark are rich in antioxidant substances, which can be used as excellent anti-aging and anti-oxidation health products; pine nuts contain 30% oil, Paint, soap and lubricating oil can be made; crude oil can be extracted from cones; pine tar can be extracted from pine roots, and the precious Chinese medicinal material - Poria cocos can be cultivated. [0003] Guangxi is the main producing area of masson pine in my country. It has established multi-level improved seed bases such as excellent provenance of masson pine - excelle...
