First, water erosion
In the usual watering, the roots of the stump are deliberately washed, so that day after day, year after year, a strong root system will grow in a few years; There are two problems that should be paid attention to when watering and scouring:
The number of 65438+ elements should be moderate. As the saying goes, it is too late. We must raise the roots to a suitable proportion according to the needs of modeling, not that the longer the roots, the better.
2. Watering and root flushing can improve efficiency by turning over pots. It is best to turn over the pot in the spring germination stage, combine root pruning and soil replacement, raise the plant above the pot surface, and then slowly wash the roots and raise it in the next growing season.
Second, Gao Peida was surrounded.
High cultivation fence is to enclose plants with root controller or linoleum and plastic board for high cultivation. Plants grow vigorously, and after the roots go deep into the lower soil, the peripheral substances are removed, and then the high-culture soil is gradually washed away. Some tree species with strong vitality and well-developed roots can also be directly washed into high-altitude soil with water according to their growth conditions, such as some boxwood, pomegranate, holly and snow. This method is also often used. In the siege of Gao Pei, we should pay attention to the following issues:
1, the height of the fence must be able to bury the whole root system, and it is best to use nutrient-free plain sand for the fence to facilitate the root system to take root and find nutrition.
2. After the fence, the water must be thoroughly watered. Because of the high soil cultivation, it is not convenient to water, but be patient. Usually, under the condition of not affecting the growth, the upper circumference is slightly dry and the lower circumference is slightly wet, which is convenient for the root system to grow downward.
3. Grasp the timing of dismantling the coaming. First, the plants grow vigorously and flourish, then make sure that the roots have been tied, and then remove the enclosure.
Third, the sleeve sand culture.
Sleeve sand culture is usually used as a means to obtain big roots. This method is often used in boxwood, pine and other tree species, with obvious effect and fast molding time. Often used in some large-scale commercial plantations.
The material used in sleeve sand culture is usually PVC sewer pipe, which is affordable and convenient to use. It has various sizes and is easy to disassemble. Is suitable for large-scale commercial planting. For home use, you can also find some large transparent beverage bottles and cut them up and down.
Sleeve sand culture method is basically the same as high culture method. It should be noted that the outer cylinder should be fixed to prevent toppling.
