Organic cultivation and rotation method for watermelons, rice and water chestnuts in spring and summer

Abstract

The invention discloses an organic cultivation and rotation method for watermelons, rice and water chestnuts in spring and summer and relates to the technical field of rotation cropping.The method comprises the steps that 1, an organic cultivation production base is built; 2, cultivation is performed in the following rotation pattern: watermelons, late rice and astragalus smicus are sequentially cultivated in spring and summer in the first year, early rice and water chestnuts are sequentially cultivated in the second year, and two years is a rotation cycle; 3, according to the quality requirements on organic agricultural products and production technological specifications, organic watermelons, organic rice (late rice and early rice) and organic water chestnuts are cultivated, and soil fertilization is realized by means of straw turnover and wet composting of organic fertilizer and planting green manure.Through the organic cultivation and rotation method, cultivation of organic watermelons, organic water chestnuts and organic rice can be carried out in the same organic cultivation production base, the method is an efficient, ecological and cyclic agricultural cultivation method, and the method is scientific and reasonable in technology, high in practicability and operability and suitable for large-scale organic cultivation and has a broad application and popularization prospect in the middle and lower reaches of Yangtze River.

Description

technical field [0001] The invention belongs to the technical field of crop rotation cultivation, and in particular relates to a crop rotation method for organic cultivation of watermelons, rice and water chestnuts in spring and summer. Background technique [0002] Organic agriculture was first proposed by European countries in the 1920s. After decades of practice and development, it has gradually attracted the attention of governments of various countries. Organic agriculture is one of the good ways to solve the problem of food safety. It is known as "sunrise industry" and has broad market prospects. Organic agricultural products are pure natural, pollution-free, safe and nutritious food, also known as "ecological food", which are produced according to the principles of organic agriculture and the production methods and standards of organic agricultural products, and are certified by organic food certification agencies. Therefore, organic cultivation must be produced in a...

Problems solved by technology

Although rice is a crop resistant to continuous cropping, since the production of organic rice cannot be controlled by chemical agents, long-term continuous cropping will also lead to the accumulation of pathogenic bacteria in the field and increase the density of insect populations. To control the occurrence of pests in the field, various methods such as soaking seeds in Chinese herbal medicine liquid and preventive spraying of botanical pesticides are used to prevent and control pests and diseases. Severely reduced yield, even cultivation failure
