Disease-resistant, draught-resistant and cold-resistant grafting technology for black tomatoes in South America

Abstract

The invention discloses a disease-resistant, draught-resistant and cold-resistant grafting technology for black tomatoes in South America. The technology belongs to a black tomato seedling grafting technology which is characterized in that excellent eggplant or tomato varieties are selected to be used as tree stocks, through a casing grafting technology, black tomato seedling scions are grafted to eggplant or tomato stock seedlings after being treated with nutrient solution containing NAA and cane sugar. The treatment is carried out through the grafting technology, so that the adaptability and the ability of black tomato seedlings for resisting against plant diseases and insect pests are greatly improved, and technical support is provided for large-scale popularization and planting of black tomatoes.

Description

technical field [0001] The invention belongs to the technical field of grafting and seedling cultivation, and in particular relates to a disease-resistant, drought-resistant, and cold-resistant grafting technology of South American black tomatoes. Background technique [0002] Black Tomato (Black Tomato) is native to South America and is a treasure of the tomato family. It is named for its red and black fruit color and fruit. Its fruit is used for both medicine and food, with strong fruit aroma, moderate sweet and sour taste, high nutritional value, especially suitable for fresh food, contains lycopene, vitamin C and antioxidants 10 times higher than red tomatoes, and is easily absorbed by the human body. It has a very good anti-cancer effect, nourishes yin and protects the kidneys, whitens the skin, and loses weight for women. It has a high commercial value, but because of its poor adaptability, weak resistance to diseases and insect pests, and low planting survival rate, i...

AI Technical Summary

Problems solved by technology

Its fruit is used for both medicine and food, with strong fruit aroma, moderate sweet and sour taste, high nutritional value, especially suitable for fresh food, contains lycopene, vitamin C and antioxidants 10 times higher than red tomatoes, and is easily absorbed by the human body. It has a very good anti-cancer effect, nourishes yin and protects the kidneys, whitens the skin, and loses weight for women. It has a high commercial value, but because of its poor adaptability, weak resistance to diseases and insect pests, and low planting survival rate, it affects black tomatoes. In my country's large-scale promotion and planting, the commerciality of black tomatoes has not been well developed and applied

At present, the cultivation of black tomato is mainly based on traditional seedling cultivation, and there are only a few areas such as Nanxianming, Gansu, Jiangsu coastal areas, Heilongjiang Mudanjiang area, Hainan, Shanghai and other few areas where there are successful records of black tomato planting, and black tomato has not been applied through grafting. report
