(1) Root absorption characteristics: The main root of celery is developed. After the main root is injured, more lateral roots grow quickly. Therefore, the seedlings should be transplanted. Most of the root groups are distributed in 20 cm deep soil layers and belong to shallow root vegetables. It is suitable for cultivation in loam or clay loam rich in organic matter (>1.5%), water retention and fertility, soil suitable pH of 6 to 7.5, salt content of less than 0.3%.
(2) Fertility requirements: The absorption of nutrients by celery during the whole growth period is consistent with the increase in biomass. The absorption dynamics of all nutrients are basically the same, showing an “S†curve. The autumn celery nutrition is also a nutrient-rich growth period. The peak period of absorption, that is, 68 to 100 days after sowing, the absorption of five elements of nitrogen, phosphorus, potassium, calcium, and magnesium accounted for more than 84% of the total absorption, of which calcium and potassium were as high as 98.1% and 90.7%. Among them, the highest amount of nitrogen was required, followed by calcium and potassium, and the least phosphorus and magnesium. The ratio of nitrogen, phosphorus, potassium, calcium, and magnesium is approximately 9.1:1.3:5.0:7.0:1.0. Generally 1000 kilograms of celery are produced. The absorption of nitrogen, phosphorus and potassium are 2.0 kg, 0.93 kg and 3.88 kg, respectively.
Best Goji procuct is in China,China is the origen of Goji Berry.Goji is a traditional,typical food in China.The majority of commercially produced goji comes from Ningxia and Xinjiang in Northwestern China, where they are grown on plantations totaling 200,000 acres.[self-published source] In Zhongning County, Ningxia, wolfberry plantations typically range between 40 and 400 hectares (100–1000 acres or 500–6000 mu) in area. As of 2005, over 10 million mu have been planted with goji in Ningxia.
Ningxia goji has been cultivated along the fertile floodplains of the Yellow River for more than 700 years and have earned a reputation throughout Asia for premium quality sometimes described commercially as "red diamonds". Government releases of annual wolfberry production, premium fruit grades, and export are based on yields from Ningxia, the region recognized with-the largest annual harvest in China, accounting for 45% of the nation's total yield of wolfberries (50,000 tons, 2013);
formation of an industrial association of growers, processors, marketers, and scholars of wolfberry cultivation to promote the berry's commercial and export potential;[16]
the nation's only source of superior grade wolfberries used by practitioners of traditional Chinese medicine.
