In the cultivation of plants, the first appropriate soil is the most fundamental, because if the soil is not appropriate, the growth of plants will be inhibited, and even some bad phenomena will appear.
In the cultivation of watercress green, the requirement for soil is to have loose, permeable, fertile and well drained soil. Generally speaking, the selected soil should have better air permeability and water retention.
When choosing the soil of Douban green, it is usually to configure and mix various media. The substrates that can be used include river sand, peat soil, perlite, vermiculite, saprophytic soil and so on. In the configuration of soil, you need to select some soil from it, and configure it. For example, you can choose the soil made of peat soil and perlite, and you can set its proportion as 6:1, which is more suitable.
Of course, there are other ways to configure the soil
Although said the method of choosing the soil of Douban green, but above the collocation of the soil, still need to pay attention to some taboos.
First of all, Douban green is not suitable for growing in the clay, because the permeability and drainage of the clay are very poor, so when selecting the soil, it is best to mix some soil with good permeability.
Secondly, in the configuration of the soil, in order to make the soil maintain a good fertility, you can add the appropriate mature organic fertilizer to the soil to make the base fertilizer.
Finally, the soil should be kept moist. The moisture content of a handful of excrement soil is 40% - 60%, not too much.
