(1) Goose-raising Model with Straw Rotation After rice harvest in mid-September, Lolium multiflorum and Dongmu -70 are sown in autumn, and the feeding period of Lolium multiflorum is 1 1 to early June of the following year. In the case of supplementing concentrate, about 200 geese can be raised per mu. After planting pasture in paddy field, improve soil, increase fertility and increase rice yield in the coming year.
The practice of Gaoyou City, Jiangsu Province: interplanting 3-4 batches, the first batch in 1 October 165438+30 chicks per mu, and the goslings coming into the market in1month; 1 The second batch of 30 PCs/mu from the end of February to the beginning of February will be listed in early April; The third batch of 60/mu in early March will be listed in mid-May; The fourth batch of 80/mu entered the market in early April and went on the market in early June. (2) Chicory and goose can be planted in spring, Sudan grass can be planted in summer, and ryegrass can be planted in autumn, which can ensure the supply of green feed all year round.
Rotation of Lolium multiflorum and Ilex petiolatum: the grass supply period of Lolium multiflorum is 165438+ 10 to May of the following year, and it cannot grow in summer; However, Ilex petiolata likes temperature and heat resistance, and it grows very vigorously in summer, and May-September is the grass supply period. These two kinds of pasture can be rotated to meet the perennial forage supply of geese.
Rotation of Lolium multiflorum and Amaranth: Lolium multiflorum was planted with Amaranth immediately after harvesting in April-May, and Lolium multiflorum was planted at 9- 10 after harvesting in August-September.
Forage and vegetable rotation: in large-scale goose raising, forage and vegetable rotation can be implemented to prevent the loss caused by green feed failure or excessive concentration and surplus during the green feed growth period. 70% of the plants are herbages, and 30% are vegetables, such as Ilex pedunculata and Chinese cabbage in February-March, spring herbage in March-May, radish and carrot in August, lettuce, lettuce and Cynanchum atratum in September, transplanting 65438+ 10 in June and autumn herbage in September-June. (3) The growth cycle of poplar in the model of planting grass and raising geese in woodland is generally around 12. In 4 ~ 5 years, poplar entered the closed period, and the benefits of planting food crops in forest land decreased or even lost. Most of the forest land is far away from villages and people's residences. The development of forest land to raise geese has a good epidemic prevention barrier, which is conducive to the prevention and control of goose diseases. Perennial ryegrass, white clover and winter pasture-perennial ryegrass is planted in woodland for 70 years, and geese graze directly. This not only improves the comprehensive benefit of forest land, but also improves the soil fertility, at the same time solves the contradiction between grain and vegetables and pasture, and reduces the cost of raising geese. There are 40 ~ 80 geese per mu of forest land, which are cultured in three batches, with 20 ~ 30 geese in each batch, and are freely stocked. (4) The mode of planting grass and raising geese in orchard Due to the large gap between fruit gardens, planting grass and raising geese is not only the utilization of land resources, but also the combination of fruit and animal husbandry, which complement each other. The advantage is that geese can eat most pests on the ground and grass in the orchard when foraging in the orchard, thus reducing the harm of pests to fruit trees. At the same time, goose manure can improve soil fertility and promote the growth of fruit trees. In addition, the orchard can be planted with grass to raise geese, and the goose house can be built near the orchard and far away from the village, which reduces the chance of epidemic spread and is conducive to epidemic prevention. Planting grass and raising geese in orchard has improved the comprehensive economic benefits of orchard. Ryegrass and clover can be planted in the orchard. (5) The mode of planting grass and raising geese in mulberry field is intercropping forage in mulberry field, raising silkworms in the second stage, namely spring silkworms and late autumn silkworms, and raising meat geese in the second stage after autumn and early spring. The main feature is to make full use of the soil fertility and light and heat resources of mulberry field, planting pasture and returning goose manure to the field, which can not only reduce the input of chemical fertilizer in mulberry field, but also reduce the production cost, effectively improve the soil structure and reduce pollution, which meets the requirements of modern agricultural development. The economic benefit is more than double that of traditional single sericulture. (6) The mode of keeping geese in shrimp-grass rotation is mainly to use the leisure time of Macrobrachium rosenbergii pond from the end of June 10 to the beginning of May of the following year to grow grass in the pond. When ryegrass is sown in May 438+10, it is generally unnecessary to apply base fertilizer after sowing, because the metabolites of Macrobrachium rosenbergii pond have formed a thick silt layer at the bottom of the pond after a season of production. Planting ryegrass in winter absorbs fertilizer from the sediment and digests the organic matter in the sediment. The grass grows fast, fresh and tender, and the yield of fresh grass is high, which is beneficial to the rapid growth and quality improvement of goslings, and also purifies the shrimp pond. Goose septic tank and grass root septic tank are beneficial to the stable and high yield of Macrobrachium rosenbergii. Generally, the first batch of goslings will be reared about 80 days before the Spring Festival (165438+1early October), and 20 goslings will be reared per mu. The second batch of goslings were captured and raised in the first batch of goslings for about 40 days, with 30 goslings per mu; The third batch of young geese was caught and raised in the second batch for about 30 days, with 50 ~ 80 geese per mu. The cumulative number of geese can be arranged according to the grass planting area per mu 100 ~ 150, and the number of geese caught each time is determined according to the growth of grass.
In addition, there are corn fields to grow grass and raise geese. By using the good temperature and humidity in the field at the late growth stage of fresh corn, the interplanting grass can be sown early, germinated early, used early and raised more geese, so as to achieve the purposes of raising geese without planting grass, saving labor, reducing costs and increasing income. Grass-goose-fish mode, planting grass to raise geese, feeding fish with goose dung to prevent the deterioration of water quality in fish ponds, changing water regularly or maintaining water circulation. Planting grass and raising geese in the dam beach can raise about 80 ~ 120 geese per mu. The mode of combining goose raising with schistosomiasis control is ecological snail control.
