Autumn cultivation methods:
Cultivation time: autumn field cultivation, 4-6 months of planting in the north and south, july-october harvest. The northern part of china is generally seeded from mid-april to may. Daylight greenhouses and plastic sheds are often concentrated in cold areas in the north, and will be planted in daejeon after early spring and evening frost。
2- fertilization of the whole field: land ready to plant the autumn, which, after the pre-harvestation, is to be ploughed in a timely manner to 30 cm deep in order to deepen the cortisol layer, further defusing the soil and increasing the soil's capacity for water preservation. Before planting, the land was fine, flat, loose, soft and thin. The autumn needs to be more fat, with 5,000 kg of decomposition and 20 kg of compound fat per acre spread over the ground, and then deep into the ground, so that it can be ploughed, so that it can be mixed, and then can open a ditch to make a gutter。
3- smooze tillage: autumn sprouts occur in time, with two to three smoozes removed, weak and small, leaving two in each den. After the seedlings are released, weeding is done in a timely manner, approximately once every 10 days. Before opening up, the first flower should be cultivated in china, with proper seedlings to promote root growth. The land is cultivated before the seal to prevent the planting of plants。
4 fertilizer pipe care: autumn is more drought- and wet-resistant and requires high air and soil moisture during growth, especially during flowering. Autumn growth and harvesting take long periods of approximately 100 days. On the basis of the application of base-based fertilizer, proper fatting is followed, with the first fertilization taking place after seeding, with urea being applied 6-7 kg per acre。
5. Plantation for leaf harvesting: during the summer it is necessary to set up a stand to protect itself from inverting, which can be supported by a 1-metre pole or a branch of a stick. In the pre-growth period, nutrient growth is prevented from leading the population, and in the mid-term and later stages, leaves are removed from the leaves below the harvest. The seeds should be left in a timely manner so that they can grow old enough to fill up with seed grains and improve their quality。
6 in due course: autumn sown from around 30 cm tall to 7-9 sprouts of real leaves, which take about 60 days to form the first fruit. The total period of subsequent harvests is 60-100 days, with a total fertility of about 120 days or more。
7. Retention storage: autumn seeding techniques are simpler. When they enter their reproductive years, they are nourished in tandem with their reproductive growth. In order to avoid inhibiting growth and reducing production, the lower fruit of the early sprouts should not be left for seeding, and it is difficult to fully mature the top of the plant, even if it is fully mature, seed grains are not full, of poor quality and not suitable for seeding. Therefore, it is advisable to choose the middle of a robust plant that meets the characteristics of the species, with a full range of seed seeds, and the old crumbs (frowning of the fruit shell and cracks), which are tanned, taken off, cleared and stored in the bags。
