Problems solved by technology

In April 2007, Guangxi Tropical Crops Research Institute used cassava twigs to bud cassava in the field, which can increase the yield of cassava. However, due to the heavy workload in the field operation, and it is easily affected by the environment and climate, it has not been widely used.
The present invention is a simple method for grafting cassava tender stems in a greenhouse with a high survival rate, which has not yet been reported

Embodiment 1

[0020] Embodiment 1: a kind of cassava tender stem greenhouse grafting method, as figure 1 As shown, short petiole (rootstock) and short petiole mutant (scion) were used for grafting.

[0021] Adopt branch grafting method grafting in greenhouse, comprise the following steps:

[0022] Step 1. Select rootstock: select 25 short-petiole cassava branches collected from the field, the branches are lignified, insert on a small pot with sandy loam, and use it as a rootstock, and start grafting after tender shoots grow;

[0023] Step 2, scion treatment: select 25 tender stems of short petiole mutant strains with intact bud eyes, no damage and robustness as scions, soak for 15 minutes with 0.2mM / L naphthaleneacetic acid;

[0024] Step 3, cut the rootstock: select 15 rootstock tender stem branches that are basically consistent with the scion thickness and maturity from 25 rootstocks, and cut into an inclined plane with an inclination of about 30 ° and a length of about 1 cm;

Embodiment 2

[0029] Embodiment 2: a kind of cassava tender stem greenhouse grafting method, as figure 2 As shown, Huanan 8 (rootstock) and cassava wild relative W14 (scion) were used for grafting.

[0030] Adopt branch grafting method grafting in greenhouse, comprise the following steps:

[0031] Step 1. Select rootstock: select 25 branches of cassava No. 8 cassava collected from the field. The branches are lignified and inserted in a small pot filled with sandy loam to be used as a rootstock. After twigs grow, grafting begins;

[0032] Step 2, scion treatment: select 25 tender stems and branches of wild relative species W14 with intact bud eyes, no damage and robustness as scions, and soak them with 0.2mM / L naphthaleneacetic acid for 20 minutes;

[0033] Step 3, cut the rootstock: select 20 rootstock tender stems and branches that are basically consistent with the scion thickness and maturity from 25 rootstocks, and cut into a slope with an inclination of about 30 ° and a length of abou...

Embodiment 3

[0038] Embodiment 3: a kind of cassava tender stem greenhouse grafting method, as image 3 As shown, Huanan No. 9 (rootstock) and Huanan No. 8 (scion) were used for grafting.

[0039] Adopt branch grafting method grafting in greenhouse, comprise the following steps:

[0040] Step 1. Selecting rootstocks: Select 25 cassava branches of No. 9 cassava collected from the field. The branches are lignified, and they are inserted in small pots filled with sand and used as rootstocks. After twigs grow, grafting begins;

[0041] Step 2, scion treatment: select 25 tender stems of Huanan No. 8 with intact bud eyes, no damage and robustness as scions, and soak them with 0.2mM / L naphthaleneacetic acid for 25 minutes;

Abstract

The invention provides a cassava tender stem greenhouse grafting method. A stem grafting method is adopted. The grafting method comprises the following steps of (1) stock selection, wherein cassava branches from fields are selected, lignified, inserted into a small basin with sandy soil and used as stocks, and grafting begin to be carried out when the tender branches come out; (2) scion treatment, wherein tender stems with intact and robust bud eyes without damage are selected as scions, and soaked through 0.2 mM / L of naphthalene acetic acid for 15-30 minutes; (3) stock peeling, wherein the tender stock branches with the thickness and the maturity of the scions being basically identical are selected, the opposite side of each bud eye is peeled into a slope which inclines by about 30 degrees and is about 1 cm long; (4) scion peeling, wherein the opposite side of each bud eye is peeled into a slope with the inclination and the length being basically identical with the inclination and the length of the peeled face of each stock; (5) jointing, wherein the stocks are aligned to the scions, after the slopes of the stocks and the scions closely fit, Parafilm opening sealing films are used for binding grafting openings firmly, and fractures of the upper ends of the scions are well sealed to the greatest extent. The method has the advantages that the low is low, the operation is easy, healing time is short, and the survival rate is high.

Description

technical field [0001] The invention relates to the field of cassava cultivation, in particular to a method for grafting cassava tender stems in a greenhouse. Background technique [0002] Plant grafting has a long history, according to written records, it has been more than 3000 years. Common grafting methods include branch grafting, bud grafting, split grafting, and skin grafting. With the development of practice and theoretical research, almost all parts of plants can be grafted. The continuous development of technology also enables grafting to break through the traditional meaning of reproduction, and is widely used in plant cultivation, basic theoretical research and breeding practice. [0003] Because cassava (Manihotesculenta Crantz) has a broad market prospect, cassava researchers from all over the world have been devoted to improving its yield. Cassava has great potential to increase production, but in general, the current production of fresh potato in my country...
