Embodiment 1
[0018] In mid-to-late October, when 50% of the rutabaga fruit on the plant is found to have cracked, collect fresh and ripe rutabaga fruit that is slightly cracked or about to crack, wrap the fruit with a paper towel with a water content of 20% and put it in Put it in a black plastic bag and put it in a room at 20°C to 25°C for 4 to 7 days until it cracks slightly. Hull the slightly cracked fruit immediately and take the seeds to keep the seed wings. Choose plump seeds with complete seed wings, and the water holding capacity is about 15. % Wet sand is mixed and stored in large trays and covered with wooden boards and placed in a room at 15°C to 25°C. In the first two weeks, keep the water holding capacity of the sand at 15% every day; from the third week, gradually increase the water holding capacity; from the fourth week, the water holding capacity can be increased to 50%. On the 30th day, soak the above-mentioned winged seeds mixed with wet sand with 0.2% potassium permangan...

[0022]In mid-to-late October, when 40% of the kotocha fruits on the plant are found to have cracked, collect fresh and ripe kotocha fruits that are slightly cracked or about to crack, wrap the fruit with a paper towel with a water content of 20% and put it in Put it in a black plastic bag and put it in a room at 20°C to 25°C for 4 days until it is slightly cracked. The slightly cracked fruit should be shelled immediately, and the seeds should be removed to keep the seed wings. After the sand is mixed, store it in a large tray and cover it with a wooden board and place it in a room at 15°C to 25°C. The storage time is 28 days, and the water holding capacity of the sand is kept at 15% every day for the first two weeks; from the 15th day, the water holding capacity is gradually increased; from the 21st day to the 28th day, the water holding capacity can be increased to 50%, and then the mass fraction Soak the above-mentioned winged seeds mixed with wet sand in 0.1% potassium perm...
