Pesticide-free planting method for caraway in high mountain

Abstract

The invention provides a pesticide-free planting method for caraway in a high mountain. The planting method comprises the following steps: S1, selecting an anti-season caraway variety planted in summer in the high mountain, and selecting an altitude of planting and the time of sowing; S2, subjecting caraway seeds to soaking treatment; S3, applying a fertilizer, and carrying out deep ploughing, thorough harrowing and ridging; and S4, after seeding is completed, carrying out covering with a sunshade net, and carrying out field management in the later period until the caraway is harvested. The planting method has the following advantages: after the caraway is sowed, a sunshade net with strong shading coefficient is adopted to cover; before the caraway seeds germinate, rainwater erosion, soil hardening, water and soil loss and seed washout can be prevented, so uniform seed density and soil humidity are maintained; meanwhile, the seedling emergence time of the caraway is longer than the seedling emergence time of ordinary weeds, and the sunshade environment is harmful for seedling emergence of the weeds, so the caraway has the advantages of neat seedling emergence, good prematurity, high yield and good quality, saves water, pesticides and labor, improves quality and safety of food, and is safe to the ecological environment.

Description

technical field [0001] The invention relates to the technical field of vegetable weeding, in particular to a pesticide-free planting method of alpine coriander. Background technique [0002] Coriander, also known as coriander, is an annual herb of Umbelliferae. The plant has a special fragrance and can be used as a seasoning. It can be planted in spring and autumn in the Hubei plain area, but the temperature is high in summer, which makes cultivation difficult and the quality is poor. [0003] However, during the growth of coriander in high mountains, usually after the soil is sown, as the seeds grow, weeds will grow in the soil, and the weeds will provide the soil for the nutrient absorption of coriander, causing poor growth of coriander; manual weeding is labor-intensive , increasing planting costs. In the prior art, herbicides are usually sprayed to achieve the purpose of weeding. However, some herbicides will remain in the coriander, which will cause harm to the human ...

Problems solved by technology

[0003] However, during the growth of coriander in high mountains, usually after the soil is sown, as the seeds grow, weeds will grow in the soil, and the weeds will provide the soil for the nutrient absorption of coriander, causing poor growth of coriander; manual weeding is labor-intensive , increasing the cost of planting

In the prior art, herbicides are usually sprayed to achieve the purpose of weeding. However, some herbicides will remain in the coriander, which will cause harm to the human body, leave soil, and affect the ecological environment.
