Eucalyptus cloeziana grafting method

Abstract

The invention discloses an eucalyptus cloeziana grafting method. The method includes the following steps: (1), selecting a time period from the spring to the early summer as grating time; (2), selecting a rootstock of 30-40cm in height, 3-6mm in rod diameter and 10cm away from the ground; (3), selecting a scion of 3-6mm in rod diameter and 15-20cm in length and with 4-8 axillary buds, and wrapping the scion by using a medical sealing film before grafting; (4), cutting two faces of the scion to be V-shaped during grafting, cutting a notch of 2.5cm in length from the middle of a rootstock grafting position, inserting the scion into the rootstock, and using a sealing film for binding; (5), moving the rootstock into a greenhouse after grafting, and maintaining humidity to be 80% and temperature to be 26 DEG C; when new leaves grow to be half of the size of mature leaves, moving a grated seedling below a shadow net of 50% in light transmittance for cultivation, and when the new leaves grow to be in the size of the mature leaves, starting to adopt all-day illumination cultivation. By the method, grafting efficiency and survival rate can be improved.

Description

technical field [0001] The invention relates to the technical field of eucalyptus grafting, in particular to a large inflorescence eucalyptus grafting method. technical background [0002] The large inflorescence Eucalyptus grows rapidly, and the stem is straight and round. The wood is yellowish-brown, with high hardness, straight texture, uniform structure, and excellent sawing performance. It is a noble wood in nature and is widely used in furniture and construction. Eucalyptus grandis is an ideal and preferred tree species for eucalyptus sawn timber cultivation, but the shortage of good seeds has seriously affected the sustainable development of Eucalyptus grandis. Practice has proved that the use of grafted seedlings to establish Eucalyptus grandis seed orchards not only has the effect of dwarfing the mother tree, but also enables early flowering and fruiting, which is an effective means and method to solve the shortage of Eucalyptus grandis seeds. Traditional eucalypt...

Problems solved by technology

Traditional eucalyptus hybrid breeding is carried out on high-quality individual plants in seed orchards or woodlands. Eucalyptus has obvious growth advantages and tall trees. In the process of artificially controlled pollination, the operation is difficult and dangerous, and has a huge impact on the climate and environment. And it is time-consuming and laborious, which affects the normal development of eucalyptus breeding work and restricts the cultivation of new eucalyptus varieties.
