Seed production and seedling cultivation method for stem-free Ficus microcarpa

Abstract

The invention discloses a seed production and seedling cultivation method for stem-free Ficus microcarpa, belonging to the technical field of a grow seedling cultivation, which comprises the following steps of producing seeds, sowing the seeds and culturing seedlings, transplanting the seedlings in a pot culture or bag cultivation mode and planting the seedlings on ground, wherein the step of producing the seeds is carried out according to the following sequence: (1) selecting a seed tree and figs; (2) preprocessing the figs; (3) producing the seeds; the preprocessed figs are mixed with fine sand according to the volume ratio of 1:1 or with peat soil according to the volume ratio of 1:0.5 to mix for the seed dressing; and the figs are crushed by means of external force, fully stirred uniformly, dried and screened to prepare the seeds. The invention has the advantages that the problem of no germination of the figs in a natural state is solved; the coefficient of the seedling cultivation of the seeds is enhanced by thousands of times than the conventional asexual seedling breeding; the price of the seedling cultivation is low; the problem of scarce seedling of the stem-free Ficus microcarpa is solved; and the method can be popularized and applied in the regions suitable for the growth of banyans in the south of China.

Description

technical field [0001] The invention relates to the technical field of tree seedling cultivation, in particular to a method for seed production and seedling cultivation of Ficus concinna var. subsessilis of the family Moraceae. technical background [0002] Sessile fig is a large evergreen tree of the genus Ficus. It is mainly distributed in southern Zhejiang, Guangxi, Guangdong and other provinces (autonomous regions) in my country. Yueqing in Wenzhou is the northernmost area where this tree species is distributed in the southern subtropical region of China. It is a climate feature. important indicator plants. It provides food for fig bees, ants and other insects, birds, bats, rats, monkeys and other animals for many years. It constitutes an important link in the food chain of the forest ecosystem and provides habitat for many arboreal animals and epiphytes. Places play a key role in the ecosystem; they have unique landscape effects such as majestic trees, thick shade, long...

Problems solved by technology

However, because there is a large amount of latex with strong viscosity in the ficus fruit, the tiny seeds are wrapped in latex and are difficult to separate and fall off. They can neither germinate nor collect in the natural state, so they cannot be sown and raised.

Therefore, the existing methods for raising seedlings related to Sessile Ficus ficus all belong to asexual propagation through document retrieval, such as adopting cuttings on big trees to carry out large pole or hard branch cutting propagation, etc., but these methods all have low propagation coefficient, seedlings in short supply, The price is expensive, the growth potential of seedlings is poor, and the tree type lacks natural forms. The most deadly thing is that this method has further damaged the resources of the ancient trees that have survived until now. is decreasing at a rate

However, with the needs of urbanization and ecological environment, the demand for this precious native tree species - Ficus sessileus is increasing, resulting in a serious shortage of this seedling
