Early sowing potato planting method

Abstract

The invention discloses an early sowing potato planting method, comprising the following steps: 1) selecting land and preparing land; 2) performing winter irrigation, building a greenhouse; 3) applying a base fertilizer; 4) treating seeds; 5) sowing, including after rotary tillage of land by a small rotary cultivator, using a row marker to mark out ridging datum lines, and ridging in line spacing of 90 cm and height of 25 cm, and making water diversion beds which are slightly lower than the ridges at interval of 5-6 m between the ridges; ditching and sowing on the ridges; covering grass; covering films; building a small shed and covering films; 6) performing field management; 7) controlling pests; 8) and harvesting. The method uses a greenhouse planting technology to excavate planting grooves on the ridges, and after potato seeds are sown, straws are laid in the planting grooves, and black films are covered, the small shed is built, to form a three-film thermal insulation structure, to ensure temperature required by potato emergence and normal growth. Through the straws, direct sunlight is shielded, preventing sunlight from hurting potato seedlings. The straws have regulation effect on temperature in the films, maintain relative stability of temperature in the films, and prevent occurrence of seedling burnt and seedling frozen phenomenon.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, in particular to a method for planting early-sowed potatoes. Background technique [0002] Potato has been cultivated in my country for more than 400 years. It is the fourth largest cultivated crop after wheat, rice and corn. With the advantages of strong adaptability and wide distribution, coupled with my country's policy support and scientific and technological support, it has become the fastest growing crop industry in my country in recent years. [0003] With the development of the potato industry, the competition between industries is becoming more and more fierce, and market price, quality and time to market have become the main means of competition. Market price competition reduces farmers' income, which will affect farmers' enthusiasm for planting in the long run and cause irreversible negative damage to the industry. Therefore, quality was the main development direction in th...

Problems solved by technology

However, the seed potatoes are sown on the straw, which is equivalent to an overhead structure. Direct sunlight can damage the potato seedlings, and when encountering rodent damage, a large area of ​​potato seedlings will die from the soil. cost
