Cultivating method for over-summer tomatoes in greenhouse

Abstract

The invention belongs to the technical field of tomato cultivation, and discloses a cultivating method for over-summer tomatoes in a greenhouse. The method comprises the steps of variety selection, cultivation of robust stocks and scions, grafting and management after the grafting, wherein the management after the grafting comprises the specific steps that grafted seedlings are placed in the plastic greenhouse under the airtight shading condition and watered with sufficient water, the air humidity is kept at 95% or above, the daytime temperature is 23-28 DEG C, and the temperature at night is15-22 DEG C; a plastic film is opened the next day, after three days, the air humidity is reduced to 76%-80%, the seedlings are exposed to light for 0.5-1 hour on the fourth day, for 1-2 hours on thefifth day and for 4-5 hours on the sixth day, from the seventh day, the seedlings are exposed to light all day, and after 7-8 days of wound healing, belts are loosened in time for transplanting the seedlings. According to the method, before sowing, disinfection treatment is conducted, harmful bacteria carried by seeds can be killed for preventing viruses, and the survival rate of the seeds is increased; grafting is conducted below cotyledons of the stocks, the grafting portions can be designed into trapezoid shapes, the contact area is large, and the survival rate is high.

Description

technical field [0001] The invention belongs to the technical field of tomato cultivation, and in particular relates to a greenhouse tomato cultivation method. Background technique [0002] Tomato, the scientific name is tomato, it not only contains rich and varied nutrition, but also has a beautiful and charming tomato shape; it is not only a delicacy in the dish, but also a beautiful product in the fruit, with many functions, it is called the magical fruit of the dish . Tomatoes are comparable to watermelons for quenching summer heat and thirst. However, the content of vitamin C in tomatoes is about 10 times that of watermelons. Moreover, due to the protection of organic acids, the vitamin C it contains is not easily destroyed during storage and cooking, and the human body has a high utilization rate. Therefore, eating tomatoes often plays an important role in treating scurvy, allergic purpura, colds and promoting wound healing. Tomatoes are also high in sugar, about 1...

Problems solved by technology

[0004] In the existing tomato cultivation process, the seedling rate after grafting is not too high, and the quality of the seedlings is not good, and they are easy to be infected with viral diseases, which increases the burden on farmers and seriously restricts the large-scale production of tomatoes; and greenhouse cultivation to prevent diseases and insect pests poor effect
