With the rapid development of the aquaculture industry, feed has become a major problem that restricts the development of the aquaculture industry. In recent years, due to the widespread use of chemical herbicides, it is no longer possible to solve the green fodder by collecting farmland vegetables. This has seriously affected the healthy development of the breeding industry, and the search for new sources of green fodder has solved the long winter in the northeast, green feed in the early spring and early summer, and Imperative. The new type of fodder introduced from Russia is a perennial root-bearing plant of Polygonaceae. It grows in clusters, has a plant height of more than 1 meter, and has large and thick leaves. Its regeneration ability is very strong. Spring, summer and autumn can be followed by long-term growth. . First, the strong resistance: suitable for the cold climate in Northeast China, minus 40 °C can be safely exposed through the winter, spring return to early morning, 0 °C can normally grow, generally no effect of frost on it, restore proper temperature, normal growth. The species also performed well in the south, with higher yields than in the north. Second, the high yield: 5-10 months of rapid growth each year, in Heilongjiang Province can be cut 4-5 per year, each pod can be cut 30,000 kilograms per mu, fertility is particularly strong, the use of root breeding, one can reproduce that year Dozens of strains can reproduce hundreds of strains in the second year. After two years, they can grow naturally and cover the surface so that weeds cannot grow. Third, the efficiency is good: suitable for extensive management, do not choose the soil, land, garden corner, pit, ditch, before and after the house can be planted in the rest of the place, dozens of strains for four pigs, 100 chickens perennial The green feed, which can be used for ten years a year, can be described as once and for all. Fourth, nutrient-rich: feed foods high nutritional value, but also a clear fragrance, can be fed fresh vegetables, but also green storage, dry storage, good palatability, chickens, ducks, geese, rabbits, pigs, dogs, sheep, cattle are Very much love to eat, especially feeding cows, can significantly increase milk production. Fifth, the cultivation is simple: the main rhizomes in the growth of continuous derivation of the roots, the main rhizome or lateral root cut into 7 cm small section, then along the ridge horizontal laying, covering the soil ten centimeters, spacing 7070 centimeters, do not shovel shovel, just pull Grass can be transplanted in the spring, summer and autumn seasons.
