A kind of off-season potato mechanized planting supporting cultivation technology

Abstract

The invention discloses an anti-season potato mechanization planting matched cultivation technique, comprising the steps of 1) selecting land, comprising the steps of carrying out soil preparation and selecting subacid loamy soil or sandy loam soil land masses with pH of 5.3-7, higher terrain, loose and fertile soil property, deep soil layer and drainage and irrigation functions; 2) preparing potato seed blocks with the weight of 45-70g for seeding, wherein each potato seed block contains 2-3 bud eyes, and a slicer is required to be disinfected when cutting the potato seed blocks; 3) seeding, wherein depth from the upper part of a tuber to the upper part of a ridge platform is 8-10cm, row spacing is 90cm, and planting distance is 18cm; 4) intertilling and earthing for 5cm when seedling emergence rate reaches up to 60%; 5) carrying out fertilizer management; 6) carrying out water management when a potato root system reaches up to 60cm, wherein soil depth is determined to be 45cm to know water supply capacity of the soil depth; 7) maintaining available water in the field to be 70-80% in a tuber forming and expanding stage; 8) preventing and controlling diseases and pests; and 9) harvesting. The anti-season potato mechanization planting matched cultivation technique disclosed by the invention has the characteristic of improving yield and quality and is applicable to widespread use.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and relates to a method for planting potatoes, in particular to a matching cultivation technique for off-season potato mechanized planting. Background technique [0002] The winter cropping area in southern my country belongs to the tropical and subtropical monsoon humid climate zone, with warm winter, abundant sunshine and abundant rainfall, which is suitable for potato growth. Southern potato winter cropping areas include three provinces of Fujian, Guangxi, and Guangdong, and southern Jiangxi, Hunan, and eastern Hubei. These areas have tens of millions of hectares of idle fields in winter and are rich in resources, providing favorable conditions for potato production. However, at present, the potato cultivation methods in winter cropping areas are backward, extensive management, improper fertilizer application, poor irrigation conditions, serious pest damage, resulting in low potato yiel...
