Embodiment

[0044] Embodiment: a kind of potato super-high-yield cultivation method comprises the following steps:

[0045] S101: Select a planting site where corn is the upper limit of altitude, the last crops are not Solanaceae, and the pH value is 6.0-7.0. In winter, the land should be plowed at least 30 cm to freeze the pupae and increase the soil moisture content. Pick them out before planting Grassroots and land leveling; in addition, the planting site should also choose a fertile, deep soil layer, sunny, sloped land that is guaranteed to be waterlogged, can be drained and irrigated at any time, has no wind damage, and has no pollution sources in the surrounding area;

[0046] S102: To control the seedling emergence, sow after the end of the local frost period. Under the premise of safety, it can be properly advanced by about 10 days. 3 Stack retting farmyard manure or 1000kg commercial organic fertilizer and mix with tillage layer;

[0047] S103: Cut the seed potatoes into pieces ...

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...
