The acorn is a famous japanese spice, mainly used to eat raw fish chips and so forth, similar to mustard, and is grown and produced in yunnan, china. Do you know how the sunflower is grown? I don't know what to say。
The technique of growing the sunflower
(i) temperature: mountain acetylene is wet, multi-year grasshoppers have a low fertility temperature of 8°c, a maximum temperature of 20°c, a maximum temperature of 15-18°c, freezing of 5°c below zero and inhibition of fertility above 20°c。
(ii) humidity: mountain sunflowers are humid, requiring 75 per cent water in the field and 80-90 per cent relative humidity in the atmosphere, less than 70 per cent or more, to the detriment of their growth and development。
(iii) land quality and field selection: mountain acetylene-growing soils are preferred for drainage, sufficient water supply, good irrigation conditions, altitude 2000-2300m, good vegetation surrounding them, slope 5-10°, and fertile gaseous sandy soil. The soil is the most suitable range of 6. 0-7. 0 ph and selects an organically rich slope of 5-15 degrees flat. In order to prevent the rise of temperature and humidity by direct solar radiation from adversely affecting the growth and development of the mountain sun, a slightly light-earthed plot should be selected。
(iv) demand for nutrients: n, p, k factor ratio: 0. 94: 0. 52。
The growth of the sunflower
1. The acorns are planted under the forest, with the vegetation chosen for the woody wood or the high bush, with broad leaf bands, trees of more than three metres high and a luminous depth of 65-80 per cent。
2. Altitude of the mountain anemone lands, located between 1,500 and 2,600 metres above sea level, is located in south-west china。
3. The area used for the hills is headed north to south of the seat or north-east to south-west, south or north-west, south, west, south-west and south-east。
4. The sandy soil is chosen for the field of acorns, with a sand content of 30-70%, a layer thickness greater than 0. 5 m, an angle of 5-40° and a ph value of 5. 9-7. 1。
5. Mountain sunflowers select leaf rock, sand rock, limestone sediment rock tops, and fire rock second, with less variable rock. The principle is not to choose mud。
6. The selection of surface water is abundant and the rainfall is greater than 1,000 ml, and the annual sunlight is less than 1,200 hours。
The morphological characteristics of the sunflower
Vegetable, circular, wave-like sawn teeth on the edge of the leaf. The handle is about 30 cm to 35 cm. Underground tubers are corrosive, 5 cm - 25 cm, 2 cm - 4 cm in diameter, light green, spicy and much stronger after milling. Roots are stubble and are distributed horizontally in soils ranging from 10 to 20 cm. Sums, capricorns, petal whites, longhorns, flowering in march-april, seeds for may-june, seeds in green form and radish seeds. It takes 1. 5 to 2 years for the acorn to be planted to harvest its roots, which produce 320 kg - 380 kg per acre。
What's that
The sunflower is a special food and health plant found in today's world. It is an extremely valuable food flavour on the international market, expensive and in demand. As a result of the special conditions in which the sunflower grows and the limited places where it is suitable for growing and growing, its products are now scarce on the international market. The acacia not only has a good taste, it has a rich nutritional component, but also contains a variety of pharmacological effects such as immuno-regulating and antibacterial, cancer-resistant and oxidizing。
