Industrial cannabis refers to cannabis which is an annual herb of cannabis with a content of less than 0.3% of tetrahydrocannabinol. Industrial hemps approved for legal cultivation are low-toxic varieties. Marijuana, once listed by the United Nations Anti-Drug Convention as one of the top three drugs alongside heroin and cocaine, is now got detoxed and become a widely used and competitive new industry in the world. Its applications include at least food and health products, medicine, animal supplies, daily necessities, cosmetics, electronics consumptions, clothing, nonwovens, composite materials, biofuels and so on more than ten fields. HEMP is now in the prime. Considering of the cultivation area of fiber-type industrial cannabis alone, the yield of industrial cannabis in the United States should not be underestimated. HEMP is highly insect resistant; cold resistance is good; deep roots help protect the soil; dense growth characteristics can easily avoid the weed growth; and vitality is higher than that of other fiber crops. Industrial hemp is especially sensitive to soil fertility response, no matter which soil is chosen or the pre-cultivation of industrial hemp, we should pay attention to soil farming measures and a large number of application of organic fertilizer, in order to achieve high yield and stable yield. Mineral nutrients that need to be obtained from the soil: nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, etc. Non-mineral elements that need to be obtained from air and water: carbon, hydrogen, oxygen, etc. Industrial hemp requires soil pH of at least 6 or more; most seeds have a vitality cycle of 1-2 years, and industrial hemp seeds have no exception, so it is important to plant them during the optimal vitality cycle of the seeds.
Specific steps for industrial hemp cultivation!
The end of January to mid-March spring selection: deep soil layer, strong water conservation and fertility, soil soft fertility, good drainage of sandy soil may be the top choice, pH to 6-6.5 as better. Rotation: rotating with crops such as rice, vegetables and jute can reduce disease and insect scare and improve its ability to grow.
Land preparation: Depending on the specific conditions of land.
Fertilization: 3/4 nutrients must be absorbed before blooming, but the seedling root system growth is slow, weak absorption capacity, so we should apply enough based fertilizer, general manure, soil manure or green manure 1500-2500kg, grass ash 40-50 kg and so on.
Sowing: choose pure and filled, full and complete, no pests and diseases, uniform size, color fresh, high germination rate, small grain species and large grain species of the thousand grain weight should be more than 20 grams and 25 grams respectively, germination rate of more than 95%, including not more than 5% impurities. Rinse the seeds with water before sowing, soak the seeds for 2-3 days, remove the seeds and exposure for 1 day, and then sowing.
The end of August to mid-September of the summer industrial hemp cultivation, the specific steps are sowing, fertilization, soil cultivation, irrigation, drainage and so on. During this period, attention should be paid to prevent wind disasters, disease and insect control and other work.
Note: During the long growth period of industry hemp, it is easy to be affected by wind disaster due to the tall stalks. For this reason, we should take fine whole land, cultivate strong seedlings, the first irrigation needs to be in the evening, small amount irrigation with high frequency, increase potassium phosphate fertilizer and other measures.
Harvest criteria: When the lower leaves of the hemp plant fall off, the stems and leaves are yellowish-white, the upper stem leaves are yellow-green or when the male flowers are in full bloom, the female flowers have small fruit.
Note: Different harvests for maturity.
Reminder: The above content mainly conveys the specific steps and precautions of industrial hemp cultivation and other issues, the specific time of cultivation and other issues need to be determined according to the actual local climate conditions.
