Abstract


Bergamot (citrus medica L.var. Sarcodactylis (Noot) Swingle) Rutaceae Citrus Hong rafters variants. Its fruit malformation was palmately cleft, the shape of the hand of the Buddha named. Bergamot valuable ornamental fruit, foliage plants, and the fruit can be used as medicine for commonly used herbs. Jinhua Bergamot traditional native ornamental plants and is a Buddha in the hands of the most ornamental varieties. Therefore, the success of Jinhua Bergamot introduction to the Changsha area cultivated ornamental plant species rich Changsha Plant Landscape type has important significance for the increase in the Changsha region. In this study, a good performance in the area of ??Jinhua four bergamot varieties: \three years of cultivation and management, research and breeding technology, mainly to the following conclusions: Bergamot bergamot varieties adaptability adaptability 4 from strong to weak order: \bergamot varieties cultivated in the region as a \Bergamot cultivation and management (1) pruning and fruit thinning: shaping major excisions and Maya are two ways of pruning. Flower and fruit thinning: thinning out full of flowers, the retained full of bisexual flowers. For ordinary kinds of bergamot, each of the branches to stay a bud can be one of the bergamot probably stay 4 to 5 buds. Thorn small species of bergamot stay 1 to 2 bud the stingless Souchong bergamot branches leaving 2 to 3 buds. (2) fertilizer and water management: water Note Pentu extent of wet and dry, over watering the dry season, rainy season, less water and do not pour depends basin pouring and pick pouring; fertilization thinner manure handling facilities Note fertilizer with boron mix of trace elements such as magnesium, can not use chlorine fertilizer production of potassium sulfate compound fertilizer Norsk Hydro. (3) pest: bergamot major diseases as anthrax and ulcer disease, using one hundred grams and high alternate mixed and used interchangeably with carbendazim prevention. Pests: spider mites, leafminer and citrus swallowtail larvae. Spider mite pest control crown and enemy dead in 2 prevention; the leafminer avermectin prevention; citrus swallowtail butterfly larvae Dimethoate EC prevention. (4) choice of soil: red soil. The composition of the bottom of the Pentu floor tiles, and then a layer of fine stone, holes and a layer of sand, and finally add soil, the soil is the main component ratio of 70% of the red soil, 20% peat 10% sand. Bergamot the shed (5) light and temperature: In early April, the average temperature is above 15 ° C; temperature higher than 30 ° C in July-August, the bergamot take shade; bergamot into the mid to late 11, the average temperature is below 5 ° C greenhouses through the winter. Bergamot reproductive technology (1) bergamot cutting propagation matrix composite matrix is ??better, a single matrix is ??relatively low. Composite the matrix sand: soil = 2:1 rooting rate was 98.9%, perlite: peat = 1:1 and soil: perlite = the 2:1 processing Rooting rate reached 96.7% and 93.3%, respectively; while single matrix of soil, perlite and vermiculite processing cuttings rooting rate of 86.3%, 91.3% and 85.5%, respectively. (2) hormone ON ROOTING rate significantly affected. The use of hormones, IBA bergamot rooting rate increased from 79.5% to 98.7%, the IBA concentration 1000 mg · L-1, rooting 98.7%, the IBA of bergamot rooting role; use of NAA cuttings trials, 1000 mg · -1, rooting rate was 94.1%. (3) Spring bergamot cuttings rooting rate, root number and root length than fall, so spring May bergamot optimum cutting time. (4) the bergamot Grafting Propagation Technology the selection Hovenia as the rootstocks, grafting studies between different varieties. Graft survival rate of the different varieties of bergamot different race bergamot graft survival rate is higher than \
