半红树作为海岸卫士的红树林重要组成之一，在滨海防护、防风固沙等生态功能

Mangrove coast guards as an important component of mangroves in the coastal protection, sand-fixing ecological function and medicinal use materials and other aspects of economic power have an important positive impact. However, for the study and the lack of any course of mangrove, mangrove parts Semi few records, and marine ecological damage after day after day, part of the semi-mangrove species already facing endangered. Tiliaceus paper, Pongamia, Pluchea volkameria inermis and the four and a half mangrove as the research object, after introduction into the interior Growth good seedlings were transplanted by tiliaceus Experimental studies show that the growth of coastal Hibiscus; through the cultivation of seeds of yellow water, yellow water sowing seeds peeled and unpeeled two treatments sowing, germination of seed, peeled or not, the results show that the water yellow peeled favor germination of seeds and germination rate; the Pluchea, cuttings volkameria inermis placed for cutting four different test matrices, the number of roots, main root comparative study rooting rate, the results show volkameria inermis LATOSOL : sand: basal and latosol: sand: fertilizer matrices both grew well in the Pluchea LATOSOL: sand: basal matrix grew well both mangrove cuttings in the cuttings Latosol growth are the worst. <br><br>Keywords: mangrove; Hibiscus; Pongamia; volkameria inermis; Pluchea; seedling transplantation; Germination; cutting matrix

As one of the important components of mangrove forest sguard coastguard, half-red tree has an important positive influence in coastal protection, wind-proof sand and other ecological functions and economic functions such as medicinal and material use. However, the study of semi-red trees and its lack, some semi-red tree research is rarely recorded, and after day after day of marine ecological destruction, some half-red tree species have been endangered. In this paper, the four semi-red trees of jaundice, water yellow skin, broad chrysanthemum and bitter-skin tree were studied, and through the yellow-spline seedling transplant experiment, the study showed that the growth condition sourafter after the introduction of jaundice from the coastal area to the interior; To study the germination of seed peeling or not, the results show that peeling is beneficial to the germination rate and germination of water-yellow-skinned seeds, and the sprigs of the broad chrysanthemum and bitter-and-yellow trees are placed in 4 different substrates for the study, and the comparative study is carried out through their root rate, the number of roots and the length of the main root. The results show that the bitter lang tree grows better in the brick red soil: sand: base fertilizer and brick red soil: sand: compound fertilizer, which is better in the two bases, and the broad chrysanthemum in the brick red soil: sand: the base fat matrix grows better, and the two semi-red tree slugs are the worst growth in the brick red soil.<br><br>Keywords: half-red tree; yellow saffron; water yellow skin; bitter tree; broad chrysanthemum; seedling transplant; germination; matrix insertion

As one of the important components of mangrove, hemimangrove has an important positive impact on the ecological functions of coastal protection, windbreak and sand fixation, as well as the economic functions of medicine and timber. However, the research on semi mangrove is still lacking, and the research on some semi mangroves is rarely recorded, and after the day-to-day marine ecological damage, some species of semi mangrove have been endangered. In this paper, four kinds of semi mangroves, i.e. hibiscus, phellodendron, chamomile and kulang tree, were selected as the research objects. Through the experiment of seedling transplantation of Hibiscus, it was found that the growth condition of the introduced Hibiscus growing in the coastal area was good. Through the experiment of seed cultivation of phellodendron, the seeds of Phellodendron were seeded with peeled seeds and seeded without peeled seeds to study the germination condition of seeds The results showed that peeling was beneficial to the germination rate and germination potential of wampee seeds. The cuttings of chamomile and kulang were placed in four different media for cuttage experiment. Through the comparative study of their rooting rate, rooting number and root length of main root, the results showed that kulang grew better in the two media of laterite: Sandy Soil: basal fertilizer and laterite: Sandy Soil: compound fertilizer, while Kubo chrysanthemum grew better in the two media of laterite Red soil: Sandy Soil: it grows well in the base fertilizer matrix, and the growth of two kinds of semi mangrove cuttings is the worst in the brick red soil.<br>Key words: semi mangrove; Hibiscus; phellodendron bark; kulang tree; Chamomile; seedling transplantation; germination; substrate cutting
