Detailed Guide to Hemp Cultivation: Field Management Cannot Be Ignored
We in China have been cultivating hemp for a very long time, with relevant records dating back to the Han Dynasty. Hemp was once used to make clothing, and later, as people gained a deeper understanding of this plant, other greater values were discovered. In addition to making clothing, hemp can also be used to produce activated carbon, and can be pressed for oil, among other uses, so more and more people are starting to grow hemp. So, are you clear about hemp cultivation methods? Let's take a look together!
Hemp Cultivation Methods
1. Select Good Seeds
The hemp varieties grown today are varieties that have been painstakingly improved by many growers of previous generations, so you no longer need to worry about poor prospects. When choosing varieties, try to pick seeds that are relatively plump, fairly uniform in size, and good in color. Secondly, although hemp has strong resistance, we still need to analyze the climate and environment of the planting site and then select the best variety. After all, seed quality is the foundation of high or low yield.
2. Select and Prepare the Land
It is recommended to choose relatively fertile land, as this facilitates drainage and gives the soil stronger permeability. When preparing the land, pay attention to plowing the soil as deeply as possible, then break the soil up finely, and finally open the land into beds, generally 1.5 m wide. Then good drainage ditches need to be made in the field, generally 20 to 30 cm wide.
3. Sow Reasonably
Generally, hemp sowing is concentrated in summer each year, starting to sow during the hotter period of July and August, mainly taking soil temperature into consideration. At this time the soil temperature is relatively high, meeting the growth conditions for hemp. Before sowing, we first need to treat the seeds, which helps the seeds germinate. The treatment method has also been introduced by the editor in other articles: simply place the selected seeds in the sun for one day. There are three sowing methods. The one we most commonly use is drilling, as it is both simple and easy to manage. Next there are broadcasting and hole sowing, which can be chosen according to your own planting habits. After scattering the seeds into the field, we need to cover them with a layer of thin soil, then cover that with a layer of straw or plastic film, so that hemp will germinate faster.
4. Scientific Fertilization
The issue of fertilization is very critical, because hemp is not quite the same as other crops. In addition to the basic base fertilizer, two topdressings are also required. Topdressing is mainly for promoting seedlings and supplementing nutrients, and the timing of each topdressing also has requirements.
5. Field Management
Field management generally includes weeding, watering and drainage, and pest and disease control. Weeding is actually fairly simple: each time you fertilize is the time to weed, so that nutrients are more easily absorbed and the soil gets to breathe, which can enhance hemp's disease resistance. Growing hemp also requires a certain amount of water, especially during its most vigorous growth period, when it basically needs watering once every three days, while at ordinary times it is basically watered about once every ten days. When there is relatively heavy rainfall, we need to drain the water promptly; waterlogging must not occur in the field.
