Autumn sunflowers are warm and, fearing frost, the whole reproductive period shall be scheduled for the frostless period, and the flowering season shall be in warm and wet seasons. The field was planted in the north and south, in april-june and in july-october。
It's often seeding
1. The seed is soaked, immersed for 12 hours before sowing and then sprung at 25-30°c, and the seed begins to sprouts about 24 hours later, waiting for 60% to 70% of the seed to sow. The seeding takes place in a den, three per cave and two to three centimetres deep. After the final frost, all areas should sow in due course, first water, then seed and then around 2 cm of soil。
2. Management, with low temperatures following the release of seedlings, should be pursued twice in a row in order to increase the temperature of the ground and contribute to the growth of seedlings. Pre-opening of the first flower strengthens the medium tillage so that the seedlings can be moderately quenched in order to develop the lagans. Following the flowering results, the plant grows faster, each time water is used to fatten it, and before it is sealed, the soil is cultivated to prevent the plant from falling。
It takes about 55 days to harvest, from sowing to forming the first nuts. The total period of subsequent harvests is 90 to 120 days, and the total period of childbearing is approximately 150 days or more. Autumn commercial fresh fruit extraction standards are 8-10 cm long, with fresh green appearances and unaging seed. If harvests are not timely, meat is ageing, fibres are increased and the value of merchandise consumption is significantly reduced. When the first harvest is generally taken, it is collected every two to four days at an early stage, with the temperature rising and the interval reduced. In august, it was collected once a day or the following day。

When the autumn matures, the autumn seeds can be collected and used as seeds to grow them in the coming year
