Problems solved by technology

However, potatoes have high requirements on the growth environment, and are vulnerable to pests and diseases during the cultivation and management process. If scientific and reasonable pests and diseases control technologies are not adopted, it is very likely that the potato yield will drop significantly, thereby reducing the economic income of farmers.

Abstract

The invention discloses a pollution-free and high-yield cultivation method of potatoes with three-layer film mulching, which includes the steps of soil preparation and fertilization, potato block treatment, timely sowing, temperature control, field management, and disease and insect pest control. The cultivation method provided by the invention changes the traditional potato cultivation form. By optimizing the cultivation method of the potatoes, the potatoes can be put on the market 20-30 days ahead of schedule, and the method can reduce chemical residues while alleviating diseases and insectpests, and significantly improves the yield and quality of the potatoes, thereby increasing the economic benefits of the growers.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a pollution-free and high-yield cultivation method for potatoes covered with three films. Background technique [0002] Potatoes are rich in nutrients and have the advantages of high yield and benefit. They are not only food and vegetable crops, but also can be used for livestock forage. They are a crop with balanced nutrition and safe production, and have broad development prospects. Potato planting has a history of 450 years in my country. With the expansion of potato planting area, edible and product development has become more and more extensive. At present, the pollution-free potato is gradually increasing in demand in the market in my country. However, the seed potato sold on the market has a The disease rate is high, which affects the commodity and product storage of potatoes. At the same time, highly toxic pesticides are widely used in the potato...
