Super-high-yield cultivation method for potatoes

Abstract

The invention discloses a super-high-yield cultivation method for potatoes, and relates to the technical field of potato planting. According to the technical scheme, the super-high-yield cultivation method is characterized by comprising the following steps: in the squaring stage, inserting 1.2 m high supports on the two sides of each narrow row in sequence at the distance of 3 m, and fixing plants to the supports; only retaining 1-2 strongest main stems in each pond, and starting to remove flower buds in the squaring stage so as to control the existing flower bud quantity of the plants to be within 5%; and spraying 25 ppm paclobutrazol twice in the squaring stage every 3 days. According to the super-high-yield cultivation method, the reasonable structure of potato groups and the robustness of individuals can be kept for a long time by pruning potato main stems, building simple supports, removing flower buds, spraying paclobutrazol, keeping the appropriate soil water content in the field, continuously applying fertilizer and preventing and controlling diseases and pests such as potato late blight as main diseases, so that the yield is increased.

Description

technical field [0001] The invention relates to the technical field of potato planting, more specifically, it relates to a super-high-yield cultivation method for potatoes. Background technique [0002] According to statistics from the Food and Agriculture Organization of the United Nations (FAO), my country's potato planting area and total output are among the top in the world. In 2018, they were 72.203 million mu and 90.3214 million tons respectively. The three traditional staple crops not only have little room for improvement in terms of production scale and per unit yield, but also the price of corn has been low for a long time, and the growth of production has slowed down or even stagnated in recent years. Since the Ministry of Agriculture put forward the potato staple food strategy in 2015, the country has paid great attention to potatoes. About two-thirds of the world's population consumes potatoes as a staple food. In Europe, potatoes have always been the staple foo...

Problems solved by technology

The existing problems are: luxuriant growth of main stems and branches, closed canopy in the field, general lodging, severe late blight, drought in spring, late defertilization, multiple flowers consume nutrients, and low yield, especially in high-altitude cold areas, such as Zhaotong City Potato per unit yield has hovered around 1 ton per mu for a long time
