Problems solved by technology

[0003] At present, in the existing rice-duck co-planting technology, there are improper selection of service ducks, unreasonable conditions and time for releasing ducks, poor control of stocking density, improper addition of auxiliary feed, and unreasonable construction of foreign enemy protection walls, which ultimately affect the survival of ducks. yield and quality
In rice production, there are unreasonable selection and construction of fields, inappropriate transplanting methods, unscientific water management and fertilization techniques, resulting in a significant reduction in rice yield and quality, which affects normal income

Embodiment 1

[0025] (1) Selection of service ducks: select small and medium-sized individuals, flexible, small food intake, strong resistance to outdoor sleeping, wide adaptability, strong vitality, long time in field activities, and wild plant-eating ducks, such as town ducks 1 No., Gaoyou duck, Jinding duck, Chaohu duck and so on.

[0026] (2) Conditions and time for ducks: The time for ducks to be stocked is after the rice is transplanted (thrown and planted) and turned green, 12 to 15 days after the early rice is planted, and 7 to 10 days after the middle and late rice is planted. Generally, the first weed germination peak will appear 7 to 10 days after the rice is planted. At this time, putting ducks into the field can achieve a more ideal weeding effect. Put ducks into the field and choose sunny days from 9:00 am to 10:00 am. At this time, the temperature is higher than in the morning, and it is still rising, which is conducive to ducks adapting to changes in ambient temperature. Wa...

Embodiment 2

[0041] Embodiment 2 various method benefit analysis

[0042] 1. Economic benefit analysis

[0043] (Daizhuang Village, Jurong City, 2012) Compared the output, materialized cost, labor cost and net income of three different models, the results are shown in Table 1.

[0044] Conventional rice-duck is used as the rice-rice-duck co-planting method in the prior art.

[0045] Table 1 Economic benefit analysis of different models

[0046]

[0047] As can be seen from the results in Table 1 above, compared with the organic rice single-cropping pattern, the rice-duck co-cropping pattern of the present invention has a significantly improved yield. Although the labor cost has increased, the final net income is still significantly improved; In the rice-duck co-cropping mode of the present invention, the yield is improved to a certain extent, and at the same time, the physical and chemical costs are significantly reduced, and the final net income is also significantly improved.

Abstract

The invention provides a rice-duck culture method. The method comprises the following steps of 1, working duck selection, 2, duck releasing condition and time selection, 3, duck releasing site and area selection, 4, natural enemy protective wall building, 5, rice field parcel selection and building, 6, rice variety selection, 7, transplanting, 8, biological control of insect pests and weeds, 9, water management, 10, fertilization and 11, duck catching and rice harvesting. Compared with the prior art, the appropriate working ducks are selected, the ducks are released in good time, and a foreign protective wall is built based on the specific releasing density; an appropriate field parcel is selected, an appropriate transplanting method is built, the appropriate water management and fertilization technology are built, finally, the duck and rice yield and quality are improved, and the ecological benefits of the rice field are remarkably improved.

Description

technical field [0001] The invention relates to a co-planting method of rice, rice and duck, and belongs to the technical field of rhesus rice planting. Background technique [0002] The planting of rice has a history of more than 7,000 years in my country, and the Chinese people have the habit of taking rice as a staple food. Traditional rice cultivation is mainly based on farmyard manure, without the use of chemical pesticides. With the growth of our country's population, the demand for food has also increased, and the issue of food safety has always been the top priority of the party and the country after liberation. In order to increase grain, the focus is on increasing the yield per unit area of ​​grain. On the one hand, new high-yield varieties are cultivated through breeding, and on the other hand, the yield per unit area is increased by researching new cultivation measures. New pesticides and new chemical fertilizers are constantly coming out, and people are fighti...
