Ecological duck breeding and rice cultivating method

Abstract

An ecological duck breeding and rice cultivating method belongs to the technologies of cultivating and planting. The method comprises the following step of putting ducklings into rice fields at different stages during rice growth till head sprouting of the rice, wherein regardless of day and night, the ducklings live in the rice fields, and the rice and the ducklings form an inter-dependence and common-growth composite ecological system. By using vigorous omnivory of the ducklings, weeds and injurious insects in the rice fields are ate off; by using uninterrupted activities of the ducklings, growth of the rice is stimulated, and intertillage muddy water effect can be generated; and simultaneously, excrement of the ducklings can serve as fertilizers, thereby producing pollution-free and safe rice and duck meat. According to measuring and calculating, one duckling lives altogether 45-50 days in the rice fields, discharges duck excrement about 10kg, each 100 ducks equal to fertilizing 1000kg duck excrement, amounting to available nitrogen 5kg, available phosphorus 7.5kg and available potassium 3.1kg; and by utilizing omnivory of ducks, weeds and injurious insects in the rice fields are ate off, and each 100 ducks can save feed 200kg, thereby greatly improving economic benefit.

Description

technical field [0001] The invention relates to breeding and planting technology, in particular to an ecological method for raising ducks and rice. Background technique [0002] The traditional method of raising ducks is generally half-grazing and half-house feeding. It mainly uses animal feed produced by rivers and lakes, aquatic plants, and green feed grown on farmland, rivers, and lakes to feed laying ducks. The obtained feed nutrition should be properly supplemented with concentrate. Grazing or semi-grazing feeding methods are adopted. Laying ducks are properly supplemented before grazing in the morning, foraging and moving in the wild most of the day, and supplementary feeding after returning to the habitat in the evening, and laying eggs in a relatively simple duck house. Due to the different climate conditions, natural feed resources, and egg production of duck flocks in various places, the feeding management is also different. [0003] The traditional method of pla...
