A kind of high-yield cultivation method of northern potato under film drip irrigation

Abstract

The embodiment of the present invention provides a method for high-yield cultivation of northern potatoes by drip irrigation under film, which relates to the field of potato cultivation, and can improve the water utilization rate and fertilizer utilization rate, and double the potato yield. The method includes: selecting soil and site preparation; installing a drip irrigation system; variety selection, seed potato treatment; sowing; irrigation and topdressing; fertilization management; and field management; The field water holding capacity is 65‑70%, the field water holding capacity is 75‑80% during the tuber formation period, the field water holding capacity is 75‑80% during the tuber expansion period, and the starch accumulation period is 60‑70% of the field water holding capacity; drip irrigation under mulch during the whole growth period of potatoes The irrigation quota is 80‑120m3 / 667m2; soluble fertilizers are used for topdressing, and pressure difference fertilization tanks are used; combined with irrigation, urea 15kg / 667m2 is topdressed.

Description

technical field [0001] The invention relates to the field of potato cultivation, in particular to a high-yield cultivation method for northern potatoes by drip irrigation under film. Background technique [0002] Potatoes are important food crops and economic crops in the north, and 80% of the production areas are distributed in arid and semi-arid economically underdeveloped hilly areas. Drought is the biggest obstacle restricting the increase of potato production in the northern region. Traditional farming depends on the weather for water use, cannot effectively use limited water resources, cannot balance the supply of nutrients, and the utilization rate of fertilizers is extremely low, resulting in low yields of potatoes. inefficient. Contents of the invention [0003] The embodiment of the present invention provides a high-yield cultivation method of drip irrigation under mulch film for northern potatoes, which can improve the water utilization rate and fertilizer util...
