A method for planting sugarcane with low toxicity

Abstract

The invention relates to the technical field of crop cultivation and particularly relates to a low-toxic effect sugarcane planting method. The low-toxic effect sugarcane planting method comprises the following field operation steps: preparing soil, applying a base fertilizer, seeding, and carrying out intertillage management. The low-toxic effect sugarcane planting method is characterized in that sugarcane furrows are ditched, black mulching films are used for covering, two sides of the mulching films are compacted, sealed solarization is performed for 15 to 20 days, and then the mulching film is removed for continued solarization for 2 to 5 days; after the base fertilizer is applied, one disease-and-insect resistant variety and at least three common varieties are selected for seeding, the disease-and-insect resistant variety is taken as a major for seeding, and the common varieties are alternatively planted; after seeding, the mulching film is adopted for covering again; a sugarcane field is checked periodically, the growing state of the common variety is taken as an emphasis for observation, and holistic governance to the sugarcane field is performed according to symptoms of the plant diseases and insect pests of the common varieties. According to the low-toxic effect sugarcane planting method provided by the invention, by coordination with growing environment, the disease and insect resisting capability of sugarcane is enhanced, forecasting for plant diseases and insect pests is enhanced, the using of pesticides is lowered, production and quality of the sugarcane are enhanced, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for planting sugarcane with low toxicity. Background technique [0002] Sugarcane is an important sugar crop in my country and a commercial crop in the tropics and subtropics. It has the characteristics of high temperature, humidity and fertilizer, and has a long growth period. The southern coastal provinces are located in the hot monsoon climate zone of South Asia, with sufficient sunlight and abundant rainfall, which are suitable for the growth of sugarcane. [0003] Sugarcane pests and diseases are the direct factors that affect the yield and quality of sugarcane. For example, sugarcane stem borers cause dead cores at the seedling stage; mid-growth larvae damage sugarcane stems, etc., resulting in low yield. Field weeds compete with sugarcane for fertilizer and provide habitat for pests. In order to ensure high yield and high quality of sugarcane, a large amou...

Problems solved by technology

[0005] However, technologies such as biological control are still not widely used. The key reason is that the sugarcane planting environment is complex and the pests are changeable. It is difficult for a single technology to deal with different sugarcane diseases.
