The latest course of grafting techniques and methods of sugar tangerine

The best harvest time for sugar orange is after October every year, so it is also called October orange. The main producing area of Shatang tangerine is located in the two regions of China. It tastes delicious and is rich in vitamins, fructose and other nutrients as well as some essential elements for the human body. It is a kind of fruit that is delicious and of great nutritional value. Usually, we use grafting to grow sugar orange. Although sugar orange can mature without grafting, the flowering and fruiting period of grafted tangerine will be earlier, and the fruit will be more stable. So how should sugar orange be grafted? Next, the pro-agricultural network will introduce the grafting technology of sugar orange for you.

Usually, when we graft sugar orange, we mainly adopt two methods: single bud cutting and single bud ventral grafting, and the pro-agriculture network mainly introduces these two methods here. Among them, splicing can only be carried out in spring, while ventral grafting has no specific seasonal restrictions and can be carried out in any season of the year.

1. Single bud cutting

1. Cutting scion

The scion usually chooses some well-growing autumn tips to use. When cutting the scion, you should first let the wider side of the branch down, cut off 1 or 2 non-full buds near the branch, and then choose a fuller bud. Cut obliquely at an angle of 45 °at a position about 1 cm below the scion, and then flip over, with the wider end of the branch facing up, starting about 0.3 cm below the bud eye you just selected. Cut the epidermis forward and pay attention to the smooth surface without the xylem layer with epidermis. Finally, turn the scion sideways, the bud point up, cut it 0.2 cm above the bud eye, and put it in clean water to prepare for grafting.

two。 Cut rootstock

The diameter of the selected rootstock should reach 0.8 cm before grafting can be carried out. Cut the rootstock from 5-10 cm from the ground, and the cutting position should be in a relatively smooth part, then cut obliquely on the cut plane at an angle of 30 °~ 45 °with the cut plane, and cut down longitudinally at the junction of the epidermis and xylem on the lower side of the cut plane. The cutting surface should also be kept smooth and smooth, and the length should be determined according to the scion made above, which is usually slightly shorter than the bud.

3. Grafting

When grafting, we should choose the rootstock and scion which are consistent with the size and length of the section, put the scion into the cortex cut by the rootstock, and the cambium of the scion should be aligned with the cambium of the rootstock. If there are rootstocks and scions that do not match the size of the section, they can also be grafted, but at least make sure that the buds of the scion are close to the cambium of the rootstock, and the incisions of the scion and rootstock are also close together.

Second, ventral grafting of single bud

Compared with single bud grafting, the operation method of single bud abdominal grafting is simpler, the grafting is not limited by time, and the survival rate of grafting is higher, and even if one grafting fails, ventral grafting can be regrafted for 1 or 2 times. The cutting method of scion is roughly the same as that of single bud cutting, but if the scion is cut into a full bud, it is easier to stick to the rootstock. The cutting method of the rootstock is also 5-10 cm from the ground, gently push 2 cm down the cortex with a grafting knife, the depth should just reach the cambium, a little white is better, and the cutting surface is also required to be smooth and smooth. Cut off about one and a half of the peeled skin, put the buds into the interface, the section corresponds to the section, and finally fix it with rope or plastic film.

The above is the introduction of the grafting technology of sand sugar orange prepared by pro-agricultural network, which has also been introduced in front of the pro-agricultural network. The grafting of sand sugar orange has a certain positive effect on its flowering and fruiting, and the yield after grafting has a certain relationship with the quality of rootstocks. In our country, red tangerine and sour orange are usually used as rootstocks. Such sugar orange produces early and has a large yield, which is more conducive to improve the economic benefits of growers.
