This article includes classification, breeding, germplasm introduction, planting and development suggestions of industrial hemp. Industrial hemp, which is considered as a cash crop with high added value, has been recorded in Chinese history. With the opening up of industrial hemp cultivation in many states of north America and European in recent two years, more enterprises begin to pay attention to the market of industrial hemp or cannabis. From the characteristics of industrial hemp that have been developed and to be developed, we can say that there is great potential!

 

 

Classification of industrial hemp

 

1. Botanical classification: Cannabis belongs to the cannabis family and belongs to the annual herb. The cannabis species is divided into two subspecies: north subspecies and India subspecies.

 

2. Classification by content of THC: industrial hemp and drug hemp.

Industrial marijuana generally refers to the THC content between 0.05% and 1%, and the THC content of the drug marijuana is between 3% and 20%.

 

3. By region: southern varieties and northern varieties.

When the growth period of northern hemp is prolonged, CBD will decrease, while the growth period of southern hemp is shortened and yield decreases.

 

Industrial hemp cultivation spread from China to the world

 

China is one of the sources of hemp, and also one of the grains in ancient China.

Archaeological evidence suggests that cannabis cultivation in China has a history of 4-5,000 years.

Marijuana as fiber crop was introduced from China to Egypt, and then introduced to Europe in 1000-2000 BC, after 500 AD is widely cultivated in Europe. It was only cultivated in South America in 1545, mainly in Chile. Cultivation began in North America in 1606, first in the American state of Louisiana, and then in Kentucky where it flourished.

 

Therefore, China's hemp germplasm resources have certain advantages, but China has not carried out research on recreational hemp, without foundation, the research on high-CBD hemp lags behind that of foreign countries.

 

The study of hemp germplasm includes collection, identification and evaluation, preservation, utilization, diversity analysis, etc.

 

There are 606 hemp germplasm catalogs in China. Collected in 15 provinces of Yunnan, Guizhou, Guangxi, Sichuan, Anhui, Shandong, Shanxi, Henan, Hebei, Heilongjiang, Jilin, Liaoning, Inner Mongolia, Xinjiang and Gansu. Some 200 germplasm have been identified and preserved in the National gene Bank.

 

Introduction of hemp germplasm resources

 

Because hemp is relatively sensitive, it is difficult to introduce hemp germplasm resources. There are about 60 foreign germplasm resources listed in the catalogue of germplasm resources, mainly for fiber or seed.

In recent years, some hemp germplasm resources introduced from abroad account for a large proportion of hemp germplasm resources used in traditional Chinese medicine, which lays a foundation for rapidly improving the breeding ability of medicinal hemp in China.

 

However, introduction may also bring some problems. Different countries have different requirements on THC, which may easily lead to excessive THC.

Recreational cannabis is already available in 51 countries, where medicinal cannabis may have high THC levels, and the introduction of these high-THC varieties could cause serious problems.

 

Countries that can be imported

1. EU Countries

2. USA, Canada and Israel

3. UK

 

The introduction should go regular channels, after the introduction of timely quarantine.

Isolated planting and identification, timely destruction of high THC found, and exchange of germplasm resources shall comply with national laws.

Normal seeds can reproduce normally, but should also be segregated to prevent mixing and pest spread.

The seeds of the female flowers try to induce the male flowers to preserve their original species.

 

Steady progress has been made in the production of CBD cannabis

 

New plastic ban will increase fiber demand, composite material demand, people attaches great importance to the increase of seed oil with demand for health care, so the conditional can carry out comprehensive utilization and development of a variety of products, improve the comprehensive benefit, to prevent the volatile prices of CBD, thereby causing loss to the enterprise, such as the production of edible oil, protein, health food, feed, CBD, building materials, textile materials, and so on.

 

Promote the establishment of appropriate laws and regulations

 

THC(0.3%) is the general indicator for industrial hemp used for fiber, and THC < 0.2% is the current European standard for registered varieties.

However, THC content is affected by environment, climate and other factors. Therefore, it is not illegal as long as it does not exceed 0.5% in production.

 

At present, the cultivation of medicinal cannabis shows a rapid development trend, and high-CBD varieties are generally high in THC. Therefore, under controlled circumstances, the THC standard can be appropriately relaxed, and 0.5% or 1% can be tried.
