Winter greenhouse grafting method for English hawthorn 'Scarlet' planted in Beijing area

Abstract

The invention discloses a winter greenhouse grafting method for English hawthorn 'Scarlet' planted in Beijing area. A wild hawthorn (C.pinatifida) is selected as a rootstock and the English hawthorn 'Scarlet' is selected as a scion. The winter greenhouse grafting method includes putting the rootstock in a pot and transplanting; waking the rootstock and the scion; cutting inside and connecting in greenhouse;and managing cleft and grafted seedlings. By the winter greenhouse grafting method, the survival rates of the English hawthorn 'Scarlet' are 96.1% and 98% respectively. After a winter growth, the sprout of the grafted seedlings reaches an average length of 70cm and a thickness of 4 mm. By greenhouse grafting, the winter pruned branches of the English hawthorn 'Scarlet' are fully utilized, the grafted period is increased and the growth time of the grafted seedlings is prolonged.

Description

technical field [0001] The invention relates to a technique for grafting scarlet English hawthorn in a greenhouse in Beijing in winter. Background technique [0002] 'Scarlet' English hawthorn is an arbor plant of the genus Hawthorn in the family Rosaceae, with double-petaled pink flowers and high ornamental value in gardens. It was introduced from Paris, France to Beijing by the 948 project established by the State Forestry Administration in 2003. Years of introduced observations have shown that 'scarlet' English hawthorn can basically adapt to the climate and environment in Beijing. With appropriate cultivation techniques and measures, it grows well and has the value of popularization and application. Therefore, it is of great significance to speed up its reproduction rate. [0003] The main propagation methods of Hawthorn plants include sowing, cutting, tissue culture, grafting, etc., but the germination of its thick peel requires sand storage for two winters and one sum...

Problems solved by technology

Before grafting, after the bare root of the rootstock is lifted out, it is often fake planted, stored in sand or stored in a cellar. Whether the dormancy of the rootstock seedlings is completed or not is not mentioned, and insufficient dormancy of the rootstock seedlings will cause the rootstock to fail to wake up or the grafted seedlings to fail to germinate. Neatness; there are repeated seedlings during the grafting process, and the false planting operation is easy to damage the roots; rootstock awakening, germination, and the needs of the root system for temperature, water, and nutrients during the early growth process of the graft cannot be well obtained through false planting and other means.

There is only one article on the indoor grafting of hawthorn in winter, and the grafting method is only split grafting; after the grafted seedlings heal, they will be planted indoors, and the temperature will be cooled naturally. to grow
