Abstract

The present invention relates to a kind of two points one line graftings, including management, grafting procedures and managing after grafting before stock nursery, scion nursery, grafting, wherein the grafting procedures concrete operations include：The true leaf of stock and growing point are rejected, true leaf petiole retains 5 6mm；With grafting label from true leaf petiole to one hole of offside oblique cutting, grafting label starting point is from upward 1 2mm of petiole base, grafting label terminal is the cotyledonary node base portion opposite with petiole, jack direction and hypocotyl long axis are in the same plane, jack is completely separated by cotyledonary node upper epidermis with growing point, and nothing is connected directly position；A scion is taken, 0.5cm~0.8cm lozenges is chamfer with blade at the 1cm of cotyledon lower part, length is substantially identical as the depth of stock jack, and bamboo stick is then extracted from stock, is inserted into scion in the jack of stock rapidly, grafting finishes；It carries out transferring seedling by the two points one line grafting, it is that can pinch to sprout evil and directly tear to sprout evil in removal, and speed is fast and without influencing graft union, and raising sprouts evil and extracts efficiency.

Description

Two points one line graftings

Technical field

The present invention relates to seedling-raising technique field more particularly to a kind of two points one line graftings for melon sapling grafting.

Background technology

Currently, melon method of plant propagation with cutting specific method is：Stock true leaf and growing point are rejected, are close to any son of stock with bamboo stick Be in 30 °~45 ° one holes of oblique cutting to the lower section of another cotyledon base portion on the inside of leaf base, depth 0.5cm~0.8cm, jack direction with Stock hypocotyl long axis is in the same plane；Then a scion is taken, 0.5cm~0.8cm is chamfer with blade at the 1cm of cotyledon lower part Lozenges, length is substantially identical as the depth of stock jack, and bamboo stick is then extracted from stock, and stock is inserted into scion rapidly In jack, grafting finishes.

The above engrafting method is sprouted evil after grafting survives and is generated close to scion, need to pinch remove with finger tip when removal and sprout evil, It is careless slightly to destroy graft union position, cause graft union loosening or lesion.

Invention content

In order to solve deficiency in the prior art, the present invention provides a kind of for improving the artificial speed rejected grafting and sprout evil Two points one line graftings of rate.

The technical solution adopted by the present invention to solve the technical problems is：

A kind of two points one line graftings, which is characterized in that include the following steps：Managed before stock nursery, scion nursery, grafting, Grafting procedures and managing after grafting, wherein the grafting procedures concrete operations include：

Step 1: stock is handled：The true leaf of stock and growing point are rejected, true leaf petiole retains 5-6mm；

Step 2: with grafting label from true leaf petiole to one hole of offside oblique cutting, grafting label starting point be from the upward 1-2mm of petiole base, Grafting label terminal is the cotyledonary node base portion opposite with petiole, jack direction and hypocotyl long axis in the same plane, jack and life Long point is completely separated by cotyledonary node upper epidermis, and nothing is connected directly position；

Step 3: take a scion, 0.5cm~0.8cm lozenges is chamfer with blade at the 1cm of cotyledon lower part, length substantially with anvil The depth of the wooden jack is identical, and bamboo stick is then extracted from stock, is inserted into scion in the jack of stock rapidly, grafting finishes.

The stock nursery is that stock seed is first dried 3h~5h, then hots water treatment of seeds, sterilizes, soaks seed, is disposed After drain seed moisture content, vernalization for 24 hours~36h after be sowed in the hole tray equipped with matrix, obtain graft stock.

The scion nursery is that ingraftment seed is dried 3h~5h, then hots water treatment of seeds, sterilize, soak when stock top soil Kind, seed moisture content is drained after being disposed, ingraftment seed is sowed in hole tray, obtains grafting scion.

Management is prepares grafting when stock rough leaf grows to unitary coin-size before the grafting, and 1d will before grafting Stock and cotyledon root sprinkle profoundly water.

The managing after grafting is that preceding 3d keeps air humidity 95% or more after grafting, and day temperature is 25 DEG C~28 DEG C, nocturnal temperature is at 18 DEG C~20 DEG C；4d~7d keeps air humidity 50%~60%, day temperature at 22 DEG C~30 DEG C, Nocturnal temperature is at 16 DEG C~20 DEG C.

In conclusion the beneficial effects of the invention are as follows：It carries out transferring seedling by the two points one line grafting, sprouting evil in removal is It can pinch and sprout evil and directly tear, speed is fast and without influencing graft union, and raising sprouts evil and extracts efficiency.

Specific implementation mode

Illustrate that embodiments of the present invention, those skilled in the art can be by this explanations by particular specific embodiment below Content disclosed by book understands other advantages and effect of the present invention easily.

A kind of two points one line graftings, have specifically included following steps：

A, stock nursery

Stock seed is first dried into 3h~5h, then hots water treatment of seeds, sterilize, soak seed, seed moisture content, vernalization are drained after being disposed It is sowed at after for 24 hours~36h in the hole tray equipped with matrix, obtains graft stock；

B, scion nursery

When stock top soil, ingraftment seed is dried into 3h~5h, then hots water treatment of seeds, sterilize, soak seed, kind is drained after being disposed Sub- moisture, ingraftment seed is sowed in hole tray, obtains grafting scion；

C, it is managed before grafting

Prepare grafting when stock rough leaf grows to unitary coin-size, 1d irrigates stock and cotyledon root before grafting Water；

D, grafting procedures

Concrete operations include：

Step 3: take a scion, 0.5cm~0.8cm lozenges is chamfer with blade at the 1cm of cotyledon lower part, length substantially with anvil The depth of the wooden jack is identical, and bamboo stick is then extracted from stock, is inserted into scion in the jack of stock rapidly, grafting finishes；

E, managing after grafting；

Preceding 3d keeps air humidity 95% or more after grafting, and day temperature is at 25 DEG C~28 DEG C, and nocturnal temperature is 18 DEG C~20 ℃；4d~7d keeps air humidity 50%~60%, and day temperature is at 22 DEG C~30 DEG C, and nocturnal temperature is at 16 DEG C~20 DEG C.

The foregoing is merely the preferred embodiments of the present invention, as long as achieving the object of the present invention skill with essentially identical means Art scheme, belongs within protection scope of the present invention.
