Grass breeding rabbit three modes
The key to breeding long-haired rabbits on grass is to scientifically match the growth characteristics of different forage grasses and rationally arrange cornices to ensure that long-haired rabbits can eat green fresh forages all year round. General interplanting 1 mu of high-yielding pasture can produce about 20,000 kilograms of fresh grass a year, and can feed more than 110 long-haired rabbits. At present, we mainly use the following three kinds of grass-rabbit breeding mode: First, the Russian feed vegetable cover Italian ryegrass Russian feed food is a perennial rooted herb, once planted can be continuously harvested 7-10 years. Generally sowing in March, April-September for the harvest of fresh grass, plant growth in late November tends to slow and gradually withered, return to green in March of the following year, Italian ryegrass for annual grasses, generally in late October sowing, From December to April of the following year, the fresh grass harvested and the grain matured in June. Cultivation methods: In late March, the seedlings of Russian feed vegetables after germination were cut and transplanted to Daejeon, with a spacing of 50 cm x 60 cm. Before transplanting, apply about 2000 kg of alum per acre and about 10 kg of superphosphate. After the seedlings have survived, use diluted fecal water as the seedling fertilizer. After each harvest, combined with cultivator weeding and topdressing 1 quick-acting fertilizer, applying 15 kg of sulfuric acid hinge per mu. In mid-October, after the harvest of Russian forage vegetables, the basal fertilizer was applied between the rows (the same fertilizer species and quantity as those before Russian transplanted vegetables were transplanted), and the ryegrass were sown, and then the Italian ryegrass was sown at a seeding rate of about 1.5 kilograms per acre. Keep soil moist after sowing. After the emergence of ryegrass, if the growth of feedstuffs in Russia is still relatively strong, Russia's feed should be harvested frequently to keep its leaves from covering ryegrass. Rye ryegrass can be harvested after about one and a half months of sowing, leaving 5–6 cm in height at the time of harvest to facilitate regeneration. After ryegrass was harvested for 3 days, about 10 kg of urea or compound fertilizer was applied per acre. In mid-April the following year, when the ryegrass jointing booting and the Russian feedstuffs entered the vigorous growing season, the ryegrass was eradicated and the top dressing was applied l times to facilitate the growth of the Russian feedstuff. 2. The Rumex K-1 hybrid sour cultivar Ryegrass Rumex K-1 has the same growth characteristics as the Russian forage, so this interplanting mode can be performed with reference to the first mode. Intercropping with sweet potato Italian ryegrass In late June, 2000 kg of organic fertilizer was applied to each acre, and then ridged. The ridge bottom was 40 cm wide and 20 cm high. Sweet potatoes were planted at a spacing of 20 cm. Sweet potatoes were watered once a day after planting, and they were continuously poured for 2 days. When sweet potatoes began to be released after l months, 35 kg of ammonium bicarbonate, 15 kg of superphosphate, 15 kg of potassium chloride or 30 kg of compound fertilizer were applied per acre. 9 - In October, the harvested sweetpotato vines were fed to rabbits, and they were careful not to injure the main stem when harvesting. After each harvest, 10 kg of urea was applied per acre on rainy days, and the Italian ryegrass was sowed after harvesting of sweet potatoes in November. This cultivation mode can solve the contradiction between the first two cultivation modes and the shortage of green fresh feed between October and November. In order to achieve diversification of green fodder and consistent supply throughout the year, three kinds of forage cultivation models should be adopted simultaneously for raising rabbits, of which the one and two modes each account for 30% of the feed area and the third mode accounts for 40%.
