HEMP Cannabis in China
So far, Yunnan Province and Heilongjiang Province have legally planted industrial cannabis for several years, and now it is welcoming the golden period of development. From the perspective of the cannabis planting area of fiber industry, the planting area and output of industrial cannabis in China cannot be underestimated.
According to the China Agricultural Statistical Yearbook and the statistics of the Food and Agriculture Organization of the United Nations, China is now the country with the largest industrial cannabis cultivation area, accounting for about half of the world’s planted area.
According to the data provided by the Anti-Drug Bureau of the Yunnan Provincial Public Security Bureau, since 2010, Yunnan has approved a total of more than 220,000 mu of industrial cannabis planted in 38 counties (cities, districts) of 13 states (cities).
What kind of marijuana is China? What is the output?
➤ At present, China’s fiber cannabis is mainly distributed in Yunnan, Anhui, Heilongjiang, Shandong, Henan, Shanxi, Gansu and other provinces. From 2002 to 2011, the annual output of Chinese cannabis fiber was about 33,000 tons, accounting for 47.8% of the world.
➤ Chinese cannabis seed production is mainly in Gansu, Inner Mongolia in the northwest, Shanxi in North China and Guangxi in South China. From 2002 to 2011, the annual average production of Chinese cannabis seeds was about 40,000 tons, accounting for 40.5% of the world.
According to industry experts, China’s industrial cannabis has increased planting area and output in recent years. In 2014, the production area reached more than 25,000 hectares, including 0.7 million hectares in Yunnan Province, 0.7 million hectares in Heilongjiang Province, and 0.5 million in Anhui Province. Hectares, 0.4 million hectares in other areas.
HEMP Cannabis Planting Encyclopedia
Highly resistant to insects;
Good cold resistance;
➤ Deep roots help protect the soil;
Intensive growth characteristics, basically free of weed growth;
Vitality is higher than other fiber crops.
Industrial cannabis is particularly sensitive to soil fertility response. No matter which soil or eucalyptus is used for cultivation, attention should be paid to soil cultivation measures and the application of organic fertilizers in large quantities to achieve high yield and stability.
Mineral nutrients that need to be obtained from the soil: nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, etc.;
Obtain non-mineral elements from air and water: carbon, hydrogen, oxygen, etc.;
➤ Industrial cannabis requires a soil pH of at least 6 or higher;
➤ Most seeds have a life cycle of 1-2 years, and cannabis seeds are no exception, so be sure to plant them in the best vitality cycle of the seeds.
Specific steps for cannabis cultivation
▵ Location: The soil layer is deep, the water retention and fertility is strong, the soil is soft and fertile, and the sandy loam with good drainage is good. The pH value is 6-6.5 slightly acidic.
Rotation: Rotation with crops such as rice, vegetables and jute can reduce pests and diseases and improve storage capacity.
▵ Land preparation: According to the specific cultivation conditions, the Madi should be made in a width of 1.0-2.3 meters.
▵ Fertilization: Cannabis 3/4 nutrients must be absorbed in the early growth stage, but the root system grows slowly at the seedling stage, and the absorption capacity is weak. The base fertilizer should be applied. Generally, the manure, soil manure or green manure is 1500-2500 kg, and the plant ash is 40-50 kg.
Seeding: Choose pure and full, full and complete, no pests and diseases, uniform size, fresh color, high germination rate. The 1000-grain weight of small and large seeds should be 20g and 25g respectively, the germination rate is over 95%, and the impurity rate is not More than 5%. Rinse the seeds with water before sowing, then soak for 2-3 days, take out the sun for 1 day, and then plant.
April-July is the period of cannabis cultivation. The specific steps are intercropping, seedling, seedling, fertilization, soil cultivation, irrigation and drainage.
During this period, attention should be paid to preventing wind disasters, pest control and other work.
Note: During the growth of cannabis, due to the high stalk, it is easy to be affected by windstorm. For this reason, fine soil preparation should be adopted to cultivate strong seedlings, late irrigation water, light irrigation and irrigation; appropriate amount of nitrogen should be added, and phosphorus and potassium fertilizer should be added.
Harvest: Harvest fiber marijuana from about July to August; harvest marijuana in about September.
Harvesting standard: the middle and lower leaves of the hemp are shed, the stems and leaves are yellowish white, and the upper stems are yellow-green or when the male flowers are in full bloom and the female flowers are small. Note: It is necessary to harvest in different stages of maturity.
Reminder: The above content mainly conveys the specific steps and precautions of industrial cannabis cultivation. The detailed months of cultivation and other issues need to be determined according to the actual local climate conditions.
