Problems solved by technology

[0012] 3. The long-term survival rate of grafts is not high
The exposed cambium is only due to the beveled surface of the ear buds, and the ear buds can only heal well with the cortex of the rootstock because of the reverse insertion of the ear buds. The base of the branch and the cortex of the rootstock are torn or broken due to strong wind or moving the branch by mulberry picking, and the long-term survival rate is not high
[0013] 4. The guarantee rate of developing tree type on time is not high
Due to the small number of grafted buds, such as two ear buds or

example 1

[0028] Example 1: Implementation before sap flow in winter and early spring.

[0029] The grafting time of this method is from after the leaves of the mulberry tree fall in winter to before the sap flows in early spring. During this period, the aging mulberries did not germinate, and the cortex and wood of the rootstock could not be separated smoothly. In Sichuan, the grafting took place from late November to late March, and the time was as long as more than four months. During this period, good mulberry spikes do not need to be stored, and the spikes are fresh, which is beneficial to improve the survival rate. Because the graft gradually heals with the rootstock after the temperature is 16°C, the technical requirements for grafting during this period are higher than those for grafting after the sap flows. The method is as follows.

[0030] 1. Saw pile: According to the trunk height requirements of different tree types, choose a smooth trunk with no scars and no bark damage ...

example 2

[0036] Example 2: Implementation after the spring sap flows.

[0037] This method is grafted after the spring sap starts to flow, the rootstock has germinated, and the cortex and wood can be successfully separated. The survival rate is very high, but the storage management of the cuttings needs to be strengthened to prevent them from drying out, mildew, and germination, otherwise it will seriously affect Grafting survival rate. In Sichuan area, grafting starts from late March to early April, and the duration does not exceed the first and middle ten days of May at the latest. The method is as follows.

[0038] 1. Saw pile: The method and requirements are exactly the same as those described in Example 1.

[0039] 2. Skin cutting: on the bark around the sawed surface of the rootstock stump, use a sharp electrician's knife to vertically cut a 3.3cm long knife every 2cm along the sawed surface of the tree stump. Several incisions with a width of 2 cm and a length of 3.3 cm were fo...

Abstract

The invention discloses a novel aging mulberry rejuvenation and improvement method capable of allowing the yield to be increased in the same year after the half-year grafting time, and belongs to the technical field of gardening mulberry cultivation. The method is characterized in that ear buds are inserted in the same direction; winter bud grafting and spring bud grafting are used simultaneously; and sawed pile multi-bud grafting is performed. An improved spring sawed pile bud grafting (ear bud inserting in the same direction and multi-bud grafting) is applied by the method, and a winter skin cutting and bud grafting method is successfully applied to winter and early spring sawed pile bud grafting by using a method of skiving a rough bark of a stock, so that the grafting time is prolonged to half a year during which ear strips are not required to be stored; the number of grafted ear buds of each mulberry is increased from 2-3 to 5-10 by adopting the multi-bud grafting, so that the yield can be increased by 50-200% in the same grafting year, and mulberry tree type cultivation can be accomplished on time; and a grafting body and a stock tree body can be healed tightly and firmly by adopting the ear bud inserting in the same direction, so that the long-term survival rate of the graft body is high. According to the method, the ear bud survival rate is not less than 97%; the mulberry survival rate is not less than 99%; and the method can be widely applied to renewal rejuvenation and variety improvement of aging trees of various mulberry fields, four-edge mulberries, daxing mulberries, coriaria sinia and arbor mulberries.

Description

technical field [0001] The invention relates to a grafting technique for the rejuvenation and improvement of aging mulberry, which is characterized in that it adopts a new method of inserting ear buds along the way, using both winter and spring bud grafting, and sawing piles for multi-bud grafting, so that the grafting time can be extended to half a year and the production can be increased in the same year. It belongs to the horticultural category The technical field of mulberry cultivation. Background technique [0002] Mulberry leaves are excellent feed for silkworm rearing in rural areas. When the mulberry tree is too old or badly managed and seriously decayed, it needs to be "big waist" or grafted and rejuvenated. After the "big waist" stems down to the main trunk or a branch, not only the yield is severely reduced, but some of them die because the latent buds with thick skin can't penetrate the rough skin and germinate. Therefore, at present, for mulberry trees that a...
