Rice and duck co-cultivation method

Abstract

The invention discloses a rice and duck co-cultivation method which comprises the following steps of (1) raising rice seedlings, (2) applying a base fertilizer: 80-120 parts of farmhouse material, 20-35 parts of humic acid, 0.5-2 parts of polyaspartic acid, 1-3 parts of vermiculite powder and 5-15 parts of chitin, (3) performing transplanting, (4) putting 20-30 spotbill ducks into a rice field per mou after transplanting for 10-15 days, (5) putting a feeding material every day, and (6) mixing a Chinese herbal medicine decoction into the feeding material at a weight ratio of (3-5):1 at least once per month for duck disease prevention, wherein the Chinese herbal medicine decoction is prepared by chopping folium mori, folium nelumbinis and orchidaceae dendrobium jenkinsii, performing mixing at a weight ratio of (1-5):(1-3):1 to obtain a mixture, adding water to the mixture at a weight ratio of (15-20):1, performing extraction for 1-2h, collecting a filtrate, performing repeated extraction once, collecting a filtrate, and merging the two obtained filtrates. The method is obvious in synergistic action, high in economic benefit, ecological and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of raising shelducks, and in particular relates to a method for co-cultivating rice ducks. Background technique [0002] At present, the ecological breeding of meat ducks in my country has the following problems: [0003] 1. Abuse of antibiotics and excessive heavy metals: [0004] my country is a big country in the production and use of antibiotics, a large part of which is used for livestock and poultry farming. my country produces more than 200,000 tons of antibiotic raw materials every year, of which more than 100,000 tons of antibiotics are used in animal husbandry, accounting for about 50% of the annual antibiotic consumption. At the same time, the content of Cu and Zn in livestock and poultry manure generally exceeded the standard. [0005] 2. There are many types of duck diseases, and the incidence of mixed infection is high: [0006] Farms are more exposed to infectious diseases, stress diseases...
