Russia's fodder is also known as Conservative grass, Patriotic grass, Violet grass, Friendship grass, Russian seaweed, etc. It is a perennial grass herb of the genus Boraginaceae. It is a group of grasses, with few leaves and many stems, large and thick leaves, tender and juicy, fast tillering, and wide adaptability. It can safely pass winter at minus 40°C. As long as the water and fertilizer conditions are good, except for low-lying land and heavy-alkali land, various Land and soil can be planted. Russia has a great potential for increasing the yield of fodder. It is praised as “how high the fertilizer is, and how high the yield is.†It is rich in nutrition, high in utilization, and good in digestibility. The cultivation points are as follows: First, breeding methods: 1. Breeding: After rooting out the vigorously growing plants, cut the upper stems and leaves, leave 5 centimeters, cut the root neck longitudinally, and have 1-2 buds in the upper part of each ramet, Longer root segments can be directly planted in Daejeon after cutting, and new leaves can be grown in about 5-6 days. 2, cut root breeding: diameter 0.3 cm above the main root, lateral roots, roots can be cut root propagation, root diameter greater than 1 cm cut into two, more than 2 cm into 4 cut, cut into 4 cm long In the root section, when the seedlings are planted, the roots will be placed horizontally in the hole. The depth of the soil is 2-3 cm, and the seedlings will emerge in about 30 days. 3, root neck longitudinal cut propagation: a large number of buds and buds on the root neck, where the bud of the neck and fault block can survive, first cut the main root and lateral root, leaving the neck and then buds or buds The points were cut into several pieces and each piece was left with 1-2 buds. The plants were now cut, the buds faced upwards, and the soil was covered with 3-4 cm. The water was irrigated, and the seedlings emerged in about 7 days. Second, the cultivation time: the northern region from April to September can be planted at any time, the southern region can be planted at any time from March to October. Third, the cultivation density: When the water and fertilizer conditions are sufficient, according to the spacing of 4060 cm planting, when the water and fertilizer conditions are relatively poor can be planted by 3550 cm spacing. Mu with about 5-7 kilograms of roots. Fourth, field management 1. After the colonization and survival, the first cultivating and weeding is carried out, and the second and third cultivating weeding and earth-cultivation are carried out before the sealing and ridge-sealing. After each mulching, a cultivating and weeding is performed in combination with fertilization. 2. Top dressing: top dressing 1 time after planting. Before going back to green every year, top dressing should be done once. After each castration, combine nitrogen cultivating with cultivating cultivating 1 time and apply 10-15 kg of urea per acre. 3. Irrigation and Drainage: Water should be sprayed in due time during the dry season and after each cutting, and drainage should be conducted during the rainy season to prevent rot. 4, harvest: When the leaves up to 40-60 cm when harvesting, harvesting can not leave squat, Qi can be. 5. Feeding: Feed directly after the green cut, without chopping or beating, or dry the hay or crushed squid or silage. Generally, large pigs are fed with 4-6 kilograms of fresh grass, 2-3 kilograms of piglets, and sows are fed more than 10 kilograms, and cows, sheep, and rabbits account for 30% of total forage grass.
