Abstract

The invention discloses a planting method for improving growth and development and fruit quality of tomatoes. The planting method comprises the steps that tomato seedlings are cultivated; LED plant growth lamps are adopted as light sources to be arranged above the tomato seedlings for irradiation, and the light period every day is set to be 12 h illumination / 12 h non-illumination or 16 h illumination / 8 h non-illumination; when the tomatoes enter the flowering stage, an EDTA-Fe aqueous solution with the concentration of 100-200 [mu] mol.L <-1 > is sprayed to tomato plants, the EDTA-Fe aqueous solution is uniformly sprayed to the front and back surfaces of leaves once a week, and the tomato plants are irrigated with a nutrient solution containing no Fe element once every other month to ensure sufficient nutrients; and after the EDTA-Fe aqueous solution is sprayed for 55-65 days, when 80% of the tomatoes on the tomato plants turn red and peels are slightly soft, spraying of the EDTA-Fe aqueous solution is stopped. According to the planting method for improving growth and development and fruit quality of the tomatoes, the tomato quality improvement effect is optimal by spraying 100 to 150 [mu] mol.L <-1 > EDTA-Fe aqueous solution on the surfaces of the leaves in the photoperiod of 16 h illumination / 8 h non-illumination.

Description

technical field

[0001] The invention relates to the technical field of plant planting and cultivation, in particular to a planting method for improving tomato growth and fruit quality. Background technique

[0002] Tomato (Solanum lycopersicum L.) is one of the vegetable crops with the largest cultivated area at home and abroad, and it is also an important model crop for genetic improvement of the quality of solanaceous vegetables. Cherry tomato is a variety of cultivated tomato. Because of its short plant, short growth cycle and strong adaptability, it is widely used in tomato quality genetic improvement and physiological and biochemical research. Photoperiod is an important light environment factor that affects plant growth and development. Iron, as a key component of chlorophyll synthesis precursor, is closely related to plant photosynthesis. At present, in the process of tomato cultivation and management, there is a common problem of iron nutrition deficiency, which ser...
