Spring potato film earthing planting method

Abstract

The invention discloses a spring potato film earthing planting method. According to the method, a plastic film mulching earth exposure cultivating mode is adopted for potato planting, Holland 15G2 good seeds are cut in the last ten-day of February, celest and agricultural streptomycin are used for stirring with seeds, after accelerating germination is conducted for 4-5 d, machinery sowing is conducted, the depth of seeding is 8-10 cm, two rows are planted in one ridge, the row spacing is 1.1 m, the small line spacing is 20 cm, the planting distance is 22 cm, sowing strains / mu is 5510, common agricultural plastic mulching films are covered on the sowed seedlings, the thickness of each plastic mulching film is 7-8 Mum, the width of each plastic mulching film is 90 cm, and when terminal buds of the potatoes are 2 cm away from the earth surface, the mulching films are covered with earth for 2-3 cm. The spring potato film earthing planting method reduces the labor cost. The implementation of earthing on the films can achieve the automatic film breaking growing of the potato seedlings, the problems that machinery can not be used in filming carving and seedling placement steps and large amount of manual work is occupied are solved, the labor intensity of farmers working on potato production is relieved, the whole course mechanized production of the potatoes is achieved, the yield, the quality and the benefit are guaranteed, and meanwhile the manual work input is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of potato planting, in particular to a method for planting spring potatoes with film-covered soil. Background technique [0002] Mulch film has a good effect of increasing temperature and reducing humidity and moisture conservation, and can effectively prevent soil compaction and increase soil permeability, thereby increasing yield and income. Therefore, it is widely used in spring potato production in second-season crop production areas. Due to the toughness of the mulch, potato sprouts cannot penetrate the mulch by themselves, and the temperature under the mulch can reach above 40°C at noon, which can easily cause heat damage to potato sprouts, and in severe cases, they will be directly scalded and rotted. Therefore, when the potato shoots are just exposed to the surface, the seedlings should be manually broken in time. The holes for the seedlings should be small, and the surrounding holes should be tightl...

Problems solved by technology

Restricted by the timing of potato seedling emergence, this process needs 4-5 times to be fully completed, which not only takes time and labor, increases labor intensity and labor costs, but also tends to cause high-temperature burnt seedlings and poor quality of seedlings due to untimely release of seedlings. The high rate of potato tubers caused by the increase of the green head rate, the difficulty of weeding under the film and other problems
