How to graft peppers? A detailed explanation of the latest grafting methods

Peppers are a very popular vegetable in our country, and eating them in moderation is still very helpful to human health. Nowadays, most pepper seedling-raising methods are mainly based on grafting, and grafting can effectively increase pepper yield and variety quality, thereby improving planting benefits. But many people also do not know how to graft peppers. So today the editor has brought you the grafting techniques for peppers. Let us take a look below!

1. Cleft grafting

Cleft grafting is further divided into full cleft grafting and half cleft grafting. Full cleft grafting means cutting the entire stem cross-section of the rootstock seedling open. This method is suitable when the scion thickness and size are similar to those of the rootstock seedling. Half cleft grafting, on the other hand, means cutting open about half of the transverse stem of the rootstock seedling's stem cross-section, which is more suitable when the scion is thinner. In cleft grafting, the scion is farther from the ground, so the probability of being attacked by pathogens in the soil is smaller, disease prevention ability is strong, and the grafting survival rate is high. When carrying out cleft grafting, pepper scions should retain about 3 true leaves and be free of pests and diseases, while the rootstock should have about 4 true leaves and a height of more than 10cm. However, the procedure of cleft grafting is rather troublesome and the efficiency is not high, so it is suitable for small-scale operations.

Insertion grafting means using a bamboo stick to poke a small hole at the top or upper end of the rootstock seedling that is about the same thickness and size as the scion. Then, after trimming the bottom of the pepper scion, insert it directly into the small hole on the rootstock seedling. Insertion grafting can increase the contact area between the rootstock and scion, promote nutrient exchange between the rootstock and scion, and thereby improve the survival rate of the scion. Moreover, insertion grafting has few steps and is relatively efficient to carry out. However, it requires a relatively small scion, mostly at the seedling stage. The number of true leaves on the scion should be kept at about 2, while the rootstock should have about three, and a height of 6 cm is sufficient.

3. Tube grafting

Tube grafting is a grafting method that has gradually become popular in recent years. It is an optimized grafting method based on the splice grafting method. In the past, grafting clips were mainly used for fixation, while tube grafting mainly uses a plastic tube about 1.5 cm long for fixation. The plastic tube has an inward elastic tension that can ensure close contact between the rootstock and scion. Moreover, the elastic force of the tube is relatively strong. As the grafted seedling grows, the grafted site will continue to expand. The plastic tube can then continuously enlarge its opening as it expands, and finally fall off automatically, which can improve management efficiency considerably.

The above is a brief introduction to pepper grafting methods. There are many grafting methods for peppers. When grafting, we should reasonably choose a suitable grafting method according to the pepper variety and our own planting scale, so as to ensure the grafting survival rate and improve economic benefits. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
