There is a strange plant in Sichuan-Phyllostachys pubescens. Its growth process can be described as a miracle of nature. Bamboo is not long in the first five years of planting period. When the rainy season came in the sixth year, it jumped up for about 15 days at a speed of 6 feet every day, and finally it grew to about 90 feet, becoming the height champion in the bamboo forest. More strangely, during its growing period, other plants around Fiona Fang 10 territory stopped growing, and only after the end of its growing period did these plants get the right to grow again. In the process of "seeking the roots and asking for life", the mystery of this spectacle was unveiled. It turns out that in the first five years, it didn't grow, or even grew less. It just grows in a way that people can't easily find-it takes root underground. After working underground for five years, the root system of a young bamboo that has not yet sprouted has actually developed to more than ten meters around and plunged into the ground for nearly five meters. It is really "extensive and profound". This growth mode not only laid a solid foundation for its growth after five years, but also quietly "invaded" the root development space of other plants around it, making it impossible for them to obtain water and nutrients needed for growth. So when the rainy season comes in the sixth year, it can almost grow by itself in the form of resource monopoly, while other plants around it can only look up at the sky and sigh and watch it grow.

The undergrowth vegetation of Phyllostachys pubescens forest includes camellia, anemone, ginger, lobular lotus, alum, raspberry, myrtle, hydrangea and Schima superba. Herbs are mainly Gramineae, Cyperaceae and ferns, such as Hicriopterisglauca and Diranopterisdichotoma. Sometimes, Phyllostachys pubescens also forms various types of mixed forests with Chinese fir, Pinus massoniana, Cyclobalanopsis longipedunculata and Tetranychus urticae. In these mixed forests, Phyllostachys pubescens generally lives on the second floor, and the L floor is Pinus massoniana, which is relatively tall.

According to the different management level, bamboo forests are divided into three types in production: the first type of intensive management of bamboo forests, the main measure is loosening soil and fertilizing, with more than 200 plants per mu; The second category is the general management of bamboo forests, the main measures are cutting and tending, bamboo forests 100 ~ 200 plants; The third category is extensive management of bamboo forests, and generally no management measures are taken. Some trees have been cut down excessively, and the number of standing bamboos is only below 100. In the production of bamboo forest, it is necessary to operate according to different types of requirements and gradually expand the proportion of one type of bamboo forest.

Bamboo forest has a large area, wide distribution, high economic value and great production potential, so it has important practical significance to develop bamboo production.

Garden use

Phyllostachys pubescens is tall and green, evergreen all the year round, beautiful and straight, does not fade after frost, and appeals to both refined and popular tastes. Since ancient times, it has often been placed in gardens, Chi Pan, streams, hillsides, stone paths, patios, scenic gates and winding paths of indoor potted plants for viewing. Often planting pine plums, known as "three friends in old age". Bamboo root is shallow and light, which is an excellent material for roof greening. Hairless and pollen-free, it is also suitable for precision instrument factories and watch factories.
