Embodiment Construction

[0005] The preferred embodiments of the present invention will be described in detail below; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0006] Use fertile and well-drained soil as seedlings, apply manure and urine, and apply phosphorus fertilizer as base fertilizer. Generally, 2000-3500 kg of fully decomposed organic fertilizer is applied per 667 m2 of base fertilizer, and 10 kg of superphosphate and plant ash are added. 100 kg; or apply cake fertilizer 100 kg per 667 m2, superphosphate 50 kg and potassium sulfate 20 kg. It is also possible to apply 3500 kg of fully decomposed farmyard manure and 10 kg of diammonium phosphate per 667 m2. Choose plump seeds, sow properly, cover with a layer of fine soil after sowing, and then cover with grass slices to moisturize. After 5-6 days of budding, remove the grass slices, topdress 1-2 times, and apply manu...

Abstract

The invention discloses a lettuce cultivation method. The lettuce cultivation method comprises the following steps: during cultivation, selecting soil with fertile soil properties and good drainage effects as a seedbed, applying manure, applying a phosphate fertilizer as a base fertilizer, selecting full seeds, conducting proper sparse seeding, conducting covering with a layer of fine soil after seeding, conducting covering with grass sheets for moisturizing, germinating after 5 to 6 days, removing the grass sheets, conducting topdressing once or twice, applying 30 to 60 kg of liquid dung or 1 to 1.5 kg of urea in each place, conducting thinning once when cotyledon spreading and emergence of 1 to 2 main leaves, respectively, applying the urea in a week before field planting, spraying water in one day before pulling up seedlings so as to avoid damage to roots caused by seedling pulling, and separately field-planting the big seedlings and the small seedlings, wherein when heart leaves and outer leaves are flat, the time is proper for harvesting.
