Ridging film-mulching planting method for potatoes

Abstract

The invention discloses a ridging film-mulching planting method for potatoes. The method comprises the following steps: block dicing and germination, soil selection and preparation, ridging and fertilization, seeding and film mulching, topdressing and management, seedling killing, harvesting and the like. Through film mulching, topdressing and management, yield reduction caused by excessive pestsin a late period and influences, caused by bad quality of the potatoes, on sales and eating are avoided, the moisture condition in soil can be maintained fully, and water can be prevented from evaporating; meanwhile, by arranging micro-ditches for collecting rain, the purposes of drought resistance and water saving are achieved, the potato yield is increased, plants and soil are supplemented withpotassium, supplementation of phosphate fertilizer can also be achieved, and the fertility level of the soil and the quality and yield of the potatoes are improved; when the method is compared an existing technique, the yield of the potatoes is improved greatly, better quality of the potatoes is ensured, eating and pollution by the pests are also avoided, and the method has great practicability and is worthy of promotion and application in the future.

Description

technical field

[0001] The invention relates to the technical field of film-covered potato ridge planting, in particular to a potato ridge film-cover planting method. Background technique

[0002] Potato is the fourth largest food crop in my country after wheat, rice, and corn, and its planting patterns vary significantly among ecological types, regions, and varieties. The traditional film-covered potato planting adopts the method of on-demand planting after covering the film or placing the seed potatoes and covering the soil with film. The film is exposed and the seedlings are placed manually. Potassium sulfate 10-15kg, topdressing urea 5kg during budding stage. Potatoes are the main food crops in dry-farming areas. The traditional film-mulching method has problems such as delayed release of seedlings, serious seedling burn, low yield, and poor commodity quality. The planting technology has not been reported, and the patent of using decomposed sheep manure as the main bas...
