It's very productive, and it contains a lot of nutrients. Now that people have gradually accepted the power of black tungsten, its purchase is hot and its economic value is considerable。
The issue of planting techniques is discussed below。
1. Growth environment analysis。
Cultivation of black tungsten, generally in the western part of the country. It is highly adaptable, high-temperature, cold-resistant, drought-resistant and rare and does not have strict requirements for soil. If the light is enough, it can grow healthy. Even if it was planted in the desert, it could grow, and it was really powerful。
2. Plug-in reproduction。
The black larvae, which is generally in the form of larvae, can be produced earlier and preserve the excellent characteristics of the parent species。
This is usually how it works, before it sprouts, to cut out branches of branches that have been selected for a year and cut out branches about 20 centimetres. It is then slashed and inserted into the soil at a distance of 20 cm between lines. It's more than half the depth of the pit。
When it's plugged in, cover the soil and press on. It is important to note that water is then poured and the soil is kept wet and that the survival rate of the plume is much higher。
3. Cutting。
The results are generally three years old and five years old. Cuts are usually completed in the first three years, usually in a tiered manner, with four branches per layer. It's usually the shape of a four-story umbrella. Every year, proper cut-offs are made, and only a dozen branches will be left to the end, so that not only do not affect the production of tungsten, but it will also increase significantly, as well as its quality。
4. Management。
Before we grow, we're going to get fat. The first period was generally nitrogen fat, and the second period was generally phosphorous potassium fat. In one case, the density of the plant is to be observed, normally about 700 plants per acre, with a distance of one metre between rows and 0. 8 metres between trees. Attention should also be paid to field management, such as weeding, pine soil, timely watering, etc。
Cultivation can be done at a modest rate, and after all, there are no significant lessons to be learned from the current research phase. There are a wide variety of species, and the colours of each species are different. There is also a strict examination of the black market. Once these efforts are completed, it will be the right way to plant the black tungsten。
