Problems solved by technology

[0003] Existing cassava grafting technology mainly carries out branch grafting and bud grafting in the field, and there are certain limitations on the working space; as the patent application number is CN200710049751.2, a method for grafting soft hollow plants with stems, which discloses the following technical features : "Select the scion and rootstock with basically the same thickness and maturity, respectively cut the grafted ends of the scion and rootstock into the same slope, insert one end of the pick into the center pith of the scion, and insert the other end into the center pith of the rootstock, so that the scion Tightly coincide with the slope of the rootstock, tightly bind the grafting interface with a bandage, and seal the upper end of the scion.” There are two problems in this plan: 1. The rootstock material needs to be planted in advance or the perennial root plants of the previous year, which will bring a lot of pressure to the management of the material. 2. Using small bamboo sticks to fix the scion and rootstock materials, the operation process is difficult and cumbersome

Embodiment 1

[0023] A method for grafting and growing seedlings of cassava, comprising the steps of:

[0024] (1) The rootstock selects mature, non-injured, and intact seed stems, and uses 50% thiophanate-methyl wettable powder 700 times liquid to carry out surface disinfection. After drying, cut 10-15cm (band 5-7) with a sterile knife. Bud eyes), the incisions at both ends are flat and smooth, use sterilized tweezers and small iron hooks to take out the spongy tissue of the pith from the incision at the upper end of the rootstock, the depth is about 2-3cm, do not damage the inner tissue of the pith, and form a space for scion insertion. stand-by;

[0025] (2) the scion is selected mature, without injury, and the seed stem with good bud eyes, the diameter of the scion is slightly larger than the diameter of the rootstock pith tissue by 2-3mm, and the surface is sterilized with 700 times of liquid of 50% thiophanate-methyl wettable powder, After drying, cut out 7-10cm (with 3-5 bud eyes) w...

Abstract

The invention discloses a cassava seedling raising method by grafting, comprising the following steps: (1) rootstock selection, (2) scion selection, (3) grafting, (4) post-grafting management, (5) seedling raising, (6) field management . The present invention adopts rootstock pith space grafting, simplifies the grafting operation process, effectively breaks the "time-space" restriction on traditional grafting, can completely carry out stem grafting operation indoors, and improves grafting operation efficiency; indoor controllable light and temperature , Humidity conditions for grafting inoculum seedling management, improve management efficiency.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cassava seedling grafting method. Background technique [0002] Grafting is one of the artificial propagation and germplasm improvement methods of crops; cassava is an important tropical / subtropical starch crop, and the new cassava strains obtained through grafting can greatly improve cassava adaptability, stress resistance and yield. A practical new technology. The grafted callus tissue between cassava rootstock and scion is further differentiated, and the tissue gradually heals and becomes active to form new plants; use its strong photosynthetic efficiency to increase carbohydrate synthesis, development, and vigorous growth. formation, swelling and accumulation of starch. [0003] Existing cassava grafting technology mainly carries out branch grafting and bud grafting in the field, and there are certain limitations on the working space; as the patent application nu...
