Problems solved by technology

[0003] At present, most of the planting of marigolds still adopts the traditional planting mode, which not only has the disadvantages of low yield and poor quality, but also because marigolds are easily threatened by pests and diseases during the growth process, in order to prevent and control pests and increase profits, growers, To increase the yield, a large amount of chemical pesticides are generally used. These chemical pesticides will not only cause environmental pollution and water quality deterioration, but also there are a large amount of pesticide residues in marigold flowers, which will seriously affect the production of lutein when extracting lutein.

Embodiment 1

[0024] A method for producing and planting marigold seeds, comprising the steps of:

[0025] (1) Seed production: Seedlings were raised on April 15, and the female parent was selected at 4 grams / acre, and the male parent was 10 grams / acre; then in early June, the female parent was planted with 380-420 strains per acre, and 150 strains / acre were reserved. For sterile plants per mu, the male parent is planted with 2200-2400 plants per mu; the hybrid plants are identified and removed before the first flower of the parent parent is opened; the pollen of the male parent is collected with a powder suction device, and after drying, it is transferred to the female parent , and marked with colored lines; the female parent seeds are harvested in batches after maturity, cleaned, and packaged;

[0026] (2) Seed treatment: select the plump and mature marigold seeds harvested in step (1), soak them with 250 times dilution of 50% carbendazim for 20 minutes, then soak them in warm water at 25...

Abstract

The invention belongs to the technical field of plant planting, and discloses a marigold seed production and planting method. The marigold seed production and planting method comprises the following steps that (1), seed production is carried out; (2), seed treatment is carried out; (3), soil preparation is carried out; (4), sowing and seedling raising are carried out; (5), transplanting is carried out; (6), field management is carried out; (7), pest control is carried out. Fertilizing and irrigating are reasonably carried out, and phosphorus and potassium fertilizers are additionally applied to improve the resistance of plants, different insecticides are sprayed according to different diseases and insect pests in the early stage of the disease, spraying is carried out once every 7-10 days, and spraying is carried out 3-4 times in total; and (8), picking is carried out. According to the marigold seed production and planting method, through the steps of seed selection treatment, timely sowing and seedling raising, field transplanting, field management, pest control and harvesting, the soil is fertilized by adopting farming, physical and biological methods, and pest and disease damage is reduced, so that a safe and high-yield planting production system is obtained. The marigold produced by the planting method is high and good in quality, the yield of fresh flowers is greatly increased, the economic income of farmers is increased, good social benefits are generated, and the marigold seed production and planting method is easy to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and relates to a marigold seed production and planting method. Background technique [0002] Marigold is an annual herbaceous flower of the genus Marigold in the Asteraceae family.
