Teal breeding method through rice-duck co-culture

Abstract

The invention discloses a teal breeding method through rice-duck co-culture. The method includes: selecting a structural parcel with staggered layers at corners as a rice-duck co-culture area, applying organic base fertilizer, deeply ploughing, drawing water to nourish a field, plant-breeding elodea nuttallii, building duck houses at positions of the staggered layers, planting astragalus sinicus,alfalfa and typha angustifolia before seedling transplanting in the rice-duck co-culture area, screwing into soil after plants survive, selecting ducks small in size as breed ducks after seedling transplanting, putting the ducks into the rice-duck co-culture area in the middle of June, feeding different food materials according to different growing periods of the ducks, increasing feed feeding amount in late August, starting to withdraw the ducks, performing centralized breeding after withdrawing is completed, and re-stocking the ducks into the rice field for fattening after rice is harvestedto obtain commodity ducks. The rice field is fully utilized in the process of duck breeding to generate greater economic benefit, ecological mutually complementary and beneficial environment is built,duck breeding cost can be reduced effectively, and duck meat quality is improved.

Description

technical field [0001] The invention relates to the field of ecological seed breeding in ecological agriculture technology, in particular to a method for co-cultivating teal ducks with rice and ducks. Background technique [0002] Planting and aquaculture are both traditional agricultural economic models. There are differences and certain correlations between the two. Based on traditional agricultural thinking, the economic benefits of the two are relatively low and the agricultural risks are relatively large in their respective development. And can not give full play to the advantages of resources. As a new mixed agricultural economic structure model, the agricultural development model combining planting and breeding coordinates the various relationships between rice and animals, and efficiently utilizes various biological resources in the rice field ecosystem to maximize the use of agricultural resources. , enrich the industrial chain, and at the same time, this agricul...

Problems solved by technology

[0004] However, the technology of duck-rice co-cultivation breeding system carried out in various places is still not very perfect, and the feeding form of ducks is relatively simple. Ducks are produced rapidly and the meat is delicious, but there are generally problems such as improper selection of draft ducks, unreasonable conditions and time for stocking ducks, poor control of stocking density, and improper addition of supplementary feed, which will affect the growth promotion of rice and ducks to a certain extent. , and the utilization rate of rice fields is not high, prolonging the production cycle of aquaculture
