Method for culturing potatoes in mountainous district

Abstract

The invention discloses a method for culturing potatoes in a mountainous district. The method comprises the following steps of: A, variety selection: selecting a variety with excellent stress resistance and yielding ability and detoxified seed potatoes according to the ecology, climate, height above sea level and regional division of labor of the mountainous district; B, seeding and rational close planting: seeding in time so as to ensure that no late frost is met during emergence of seedlings, wherein the early variety is dense within a reasonable density range, the interplanting density is 2,500-3,600 plants per Mu, and the pure planting density is 4,000-4,800 plants per Mu; C, fertilization: (1) combining an organic fertilizer and an inorganic fertilizer, and (2) carrying out nutritional regulation on leaves, spraying a 45-60PPM (Parts Per ,Million) paclobutrazol solution on leaves during a squaring stage, spraying a 0.25%-0.35% monopotassium phosphate solution on leaves during a full-bloom stage, and removing flower buds during the squaring stage, thus improving the potato yield; and D, integrated control of pest and disease damage: carrying out integrated control according to the occurrence condition of pest and disease damage during the growing period. The method disclosed by the invention is easy to practice and simple and convenient to operate, adopts the excellent potato variety and the detoxified seed potatoes, is timely in seeding, rational in close planting and scientific in fertilization, and can be used for improving the yield and quality of the potatoes.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and more specifically relates to a method for cultivating potatoes in mountainous areas. The technical method can significantly increase the yield of potatoes in southwest mountainous areas, and is suitable for potato production by farmers, seed companies, agricultural scientific research and teaching, and agricultural technology promotion. and technology promotion. Background technique [0002] Potato (English name potato), also known as potato and yam, belongs to the annual herbaceous plant of Solanaceae, and is one of the main crops in my country, only after rice, corn and wheat. Potatoes have high yield, rich nutrition, strong adaptability to the environment, and are suitable for growing in cold climates. The four major potato producing areas in China are the Southwest Mountains (Bijie, Guizhou), the Northwest (Dingxi, Gansu), Inner Mongolia and the Northeast (Heilongjiang)....

Problems solved by technology

[0005] The main problems in the potato production in this area are the lack of good varieties (mixed and degraded varieties, single varieties, poor quality of seed potatoes, poor quality, unreasonable variety mix); extensiv
