Problems solved by technology

However, there are still many gaps in research and application, such as the use of local ducks in rice field fences to treat rice diseases and insect pests in double-cropping rice areas;
At the same time, foreign research and application focus on ecological benefits, and economic benefits are not prominent, so it is difficult to become a conscious action of farmers

Embodiment Construction

[0017] Moderate scale operation. According to the principle of household farming and concentrated duck release, every 30 mu, select a farmer with a certain technical foundation to carry out ecological planting. That is to say, each household is responsible for the farming operation, the paddy fields are drained and irrigated, the fences are used to raise ducks, and the prevention and control of Cordyceps disease are all managed by professional duck raising households in a centralized and unified manner.

[0018] Auxiliary plant protection technology. Putting ducks through the fence improves the environmental conditions for cultivation, and the pests and diseases will be greatly reduced. However, if the rainy weather lasts for too long in southern rice areas, it may cause serious damages such as sheath blight and rice blast. Therefore, biological control and other physical methods must be supplemented. The main technologies are as follows:

Abstract

The present invention discloses a paddy field rail duck raising technology. Rice, insect, duckweed and duck constituting one biological chain are made to control each other; the time and the space for the four kinds of organisms to constitute the complex colony are controlled based on the rice growth rule and the symbiotic biological environment for rice and duck is improved to realize the pollution-less rice plantation and duck raising. By stimulating natural biological system, the duck raising in paddy field can control the harmful disease, pest and weed, reduce pesticide amount, produce green food material and increase rice field output value.

Description

Technical field: [0001] The invention relates to a breeding technique, in particular to a technique of raising ducks by fences in paddy fields. Background technique: [0002] With the occurrence of pests, diseases, and weeds becoming more and more serious, the large-scale application of pesticides in crop production has become an example of technical measures. Extensive use of pesticides not only seriously pollutes the environment, affects the quality of crops, but also increases the cost of agricultural production. Pesticides are generally not used in natural ecosystems, and the stability of the system is mainly maintained by the self-regulation, reconstruction and recovery of the system. There have been many studies on the use of biological control of rice and cotton pests and diseases. For example, European and American countries use parasitoids to control rice and cotton pests to achieve the purpose of protecting the normal growth of crops without using pesticides, and ...
