Planting method of marigold

Abstract

The invention discloses a marigold planting method in the technical field of plant planting. The marigold planting method comprises the following steps: step a, primary soil preparation; step b, secondary soil preparation: ridging is performed on the planting land, the ridge length is 5-8 m, the ridge width is 1.5-1.8 m, then water is sprayed on the ridges, and the humidity of the ridges is kept at 15-20%; c, preparing a nutrient solution: preparing the following raw materials in parts by weight: 5-8 parts of diammonium phosphate, 3-4 parts of urea, 4-7 parts of potassium sulfate and 10-15 parts of water, and mixing and uniformly stirring the raw materials in parts by weight to obtain the nutrient solution; step d, planting: transplanting marigold seedlings to ridges, planting two rows of marigold seedlings in each ridge with the row spacing of 45-50cm and the plant spacing of 30-35cm, and then spraying a nutrient solution; and e, planting field management: when the height of the marigold seedlings is 27-30 cm, soil is taken from the planting field and cultivated on the surfaces of ridges, and then water is sprayed to keep the humidity of the ridges to be 8-10%. By adopting the scheme to plant the marigold, the yield of the marigold is greatly improved.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a planting method of marigolds. Background technique [0002] Marigold, also known as smelly hibiscus, belongs to Compositae and is an important pigment plant. Because it is an ideal raw material for natural lutein, it has been widely planted, forming the source link in the lutein production industry chain. Lutein is a class that can delay vision degeneration and blindness caused by macular degeneration in the elderly, and even benefit the treatment of cardiovascular sclerosis, coronary heart disease and tumor diseases caused by body aging. [0003] At present, the planting of marigolds mainly includes: site preparation, transplanting, fertilization and management. During site preparation, lime is sprinkled on the planting ground for disinfection. After the disinfection is completed, the marigolds that have completed seedling cultivation are directly planted on the planti...

[0003] At present, the planting of marigolds mainly includes: site preparation, transplanting, fertilization and management. During site preparation, lime is sprinkled on the planting ground for disinfection. After the disinfection is completed, the marigolds that have completed seedling cultivation are directly planted on the planting ground, and then sprinkled with water and fertilized. , adopting such a planting method is too single, and cannot provide sufficient nutrients for the growth of marigolds; and the management of marigolds has not been paid attention to, which leads to very low yields of marigolds, and requires a large amount of planting area at the same time. Affect the income of planters, and the input-output ratio is small
