1. Soil selection
Autumn sunflowers are drought-resistant, wet-resistant, insatiable, with the result periods requiring adequate moisture for the growth of the fruit, and vice versa
Poor quality; autumn accelerants are highly adapted to the soil but are based on deep, fertile, fertile and fertile land or sandy soil
Advantage; requiring complete potassium nitrogen phosphorus for fertilizers, mainly for the pre-growth period, mainly for phosphorus, potassium fat for the mid-term and later periods, and too much nitrogen fatting to plant
The result is long, delayed flowering, and the lack of nitrogen fertilizer reduces production due to poor growth of the plant。
2. Cultivation season
Cultivation in the yangtze basin and in the south china region during the frostless period can take place in the yellow autumn springs, summers and autumns, but mainly in spring。
Seeding in april, harvest in september; planting in june, harvest in october; planting in july, harvest in november. It's early
Cultivation is covered with huts, small arch sheds or membranes, and is dominated by field cultivation during the season. North cultivation usually takes place during the frostless period
High yields can also be obtained from live post-renewal or 15-day seedling migration。
3. Tunnels
After the harvest of the former crop, the soil was torn up for 10 and 15 days, and drenched, usually at 1. 3 metres (4 feet); and the ravine was 25 miles deep
30 cm; 2,000 kg of manure per acre of manure and 40 kg of compound fattening, with sufficient fertilizer and soil
Intermingled, seeded or planted after 5 days。
4. Cultivation
Taiwan's five-four yellow autumn is a straight root system with weak regenerative capacity, and the spring field is often used for live broadcasting. Autumn skin is tougher
It can be immersed for 24 hours, washed for water once every 5 hours and 6 hours, or removed and placed at 25°30°c. Down
Sprouts, about 3 days of open white sowing. It's about 60 centimetres away, 18 centimetres away, 6,000 saplings per acre
Over. Early spring protected areas can be planted with seedlings, 30 days old and 40 days old. The ideal type of taiwan's five-fifty plant is tight
It's not crazy, it's not crazy, it's anti-aggressive, so it's good to plant high yield。
5. Field management
Weeding and earth-breeding must be cultivated three times in the pre-production period, until the containment period. The pursuit of fattening is dominated by organic fat, with proper potassium phosphorus
Fertilizer: 1 per cent seedling fattening, 1,000 kg of manure and 3 urea 5 kg of urea per acre, 5 days after seeding or planting
Second pursuit of fertilizer, 1,500 kg of manure and chlorine per acre, prior to flowering (25 days after seeding or planting)
Potassium potassium 5 〜 8 kg; once more in the flowering season, 2000 kg of manure per acre and 8 〜10 potassium chloride
Kg. In the future, proper pursuit of fertilizers based on the strength of the plant should not be applied in an abusive manner to avoid nutritional growth and reproductive growth disorders。
During the flowering results, “in order to improve the ventilation conditions, it is important that the leaves that have been harvested be cut off in time. Yellow autumn
Wetness, high air and soil moisture requirements, particularly when flowering results do not lead to water scarcity, timely and adequate water supply
The fruit expands rapidly, but not too much water, so that the rain will be drained in time for the plants to grow properly and increase their singles
Area yield。
6. Pest management
Taiwan's five-favorite yellow sunflowers are highly resistant to disease and generally have very few diseases; the pests are mainly aphids, which are treated with aphids, etc. Fan
In the case of long-term damage to bridge worms, pyramethrin and so on is used。
Collection
The autumn blooms from the beginning of the festival of 4 〜8 and, at the right temperature, two 〜4 days after the flower is cut
Young nuts grow up to 6 〜8 cm long, or about 12 g heavy, are collected on the market, with low yields and late fibres
It's heavy. The pre-harvest period averages 2 and 3 days, and the harvest period normally takes 1 harvest day or day after harvest
In general, three or four days was taken once. Autumn hairs, leaves, and stabbings are on the fruit
Skin was stabbed, itchy。
8. Autumn utilization value
The autumn is fed mainly by green herbs and leaves, buds and flowers. 2 grams of protein per 100 grams of seedlings, vitamin c31 milligrams
G, vitamin a6 mg, calcium 83 mg, cellulose 1 g. Regular consumption helps digestion, protects the stomach, liver and skin
The skin and the kidney function. Herbs, seeds, roots can be drugged to treat diseases such as haemorrhoids, gills, stomach inflammation, stomach ulcer, etc
Sick. The acupuncture is fresh, and tastes unique to them. Autumn
The leaves contain a wealth of vitamin a, c and trace elements such as calcium, potassium, zinc and so forth. Autumn seeds are bigger
For use, because of its protein content similar to that of pulses, high protein powder can be processed and separated from it for baking
Quality edible oils; seeds used to extract oil, which are unsaturated fatty acids, sour acids, and more than 70 per cent oils, which are good-quality edible oils; dry seeds
It's popular in central america, called "caffeine-free coffee" yellow. Aoi
The flowers are beautiful, they can be made from a pot or cut. All in all, the economic value of the autumn is so high that it's worth a lot of effort
Outreach。
9. Current domestic development and utilization of products
Autumn sunflower tea and old mackerel soup and autumn sunflower butter and autumn seed, and so on。
