It is a perennial herbaceous plant. Originated from the Russian Caucasus and Siberia, it has been proved through experiments in cultivation, propagation and processing in China that the concentrated grass is a high-quality, high-yield pasture with high grass yield, high nutritional value, good palatability and resistance to stress.
The polymer grass plant is 0.8 meters to 1 meter high, with a well-developed root system and strong regeneration capacity. It can reach up to 50 cm deep in the soil and effectively use deep soil nutrients and moisture. The leaves are large, developed and long oval. The leaves are divided into root cluster leaves and stem leaves, and the number of leaves is up to 200 or more. Leaves hypertrophy, tender and juicy, lush stems and leaves. Spring, summer and autumn continue to pump flowers. Flowers clustered, lavender or yellowish, without seeds.
Polymer grass is suitable for humid climate conditions. The scope of adaptation to climate and soil conditions is relatively large. It is hardy and cold, and its roots can safely pass winter at low temperature of -40°C. It can still grow well in high temperature areas in the south. The fastest growth is at 22-28°C, slower than 7°C, and stopped at 5°C. When the temperature is above 20°C, the soil grows fastest when the water holding capacity is 70%-80%, and the average daily growth can reach 3 cm. Polymeric grasses require strict soil requirements. In addition to low-lying land and heavy saline-alkali soils, the soil can generally grow. The best soil is a deep, fertile loam soil.
Cone grass can be used continuously for more than 20 years. Compared with planting and feeding of more than 20 forage grasses, such as alfalfa, pine cone herb and Rumex, it has three unique economic characteristics: First, it has high grass yield and strong regeneration ability. Spring, summer, and autumn can be followed by long cuts. In the first quarter of the growing season, northern regions can be cut 3-4 times, and the south can be cut 4-6 times. Generally speaking, the output of fresh grass per 667 square meters is 0.4 million kg-0.5 million kg. The second is good palatability and high digestibility. The leaves are tender and juicy, aromatic in smell and soft in texture. After the fresh grass is chopped or beaten, it emits a light cucumber aroma. Pigs, cows, sheep, rabbits, chickens, ducks, geese, ostriches, and herbivorous fish all like to eat, and can significantly promote the growth and development of livestock and poultry. After testing, fresh grass dry matter contains 24.3% of crude protein, 5.9% of crude fat, and 10.1% of crude fiber. Also contains a large number of allantoin and vitamin B12, can prevent and treat livestock and poultry enteritis, do not diarrhea after eating animals.
I. Cultivation techniques
1. Select and prepare land. Polymer grass has strong resistance to stress and growth. The cultivated land should be selected from fertile soils with flat terrain and deep soil layers, and can also be planted using river banks, various beach areas, barren slopes, orchard gardens, and various abandoned lands. Polymeric grass like water fertilizer, fertilization after significant effect. Various farm manures, manures or ring fertilizers can be applied, and the effect of applying pig manure is particularly significant.
2. Planting. Converged grass is mainly vegetatively propagated, and it is currently mainly propagated by cutting roots. The planting density depends on the seed quality, soil fertility and management level: the soil fertility is poor and the management level is low. The plant spacing is 50 cm x 40 cm, 3000-3500 seedlings per 667 m2, and the soil is fertile. The row spacing is 70 cm x 50 cm or 60 cm x 50 cm, and 1800-2000 saplings per 667 m2, of which the highest yield is 60 cm x 50 cm.
3. Cut root breeding methods. Concentrated grasses have a good ability to regenerate, and cut off the roots to generate new shoots from the top cut. All roots and roots with a diameter of 0.3 cm or more can be used as root seedlings. The size of the root cutting segment is determined according to the number of roots, and the general cutting length is 2-5 cm. Roots with a root thickness of not less than 0.8 cm and a length of more than 5 cm can be cut perpendicularly (that is, longitudinally) into two valves. Roots with a diameter of 1.5 cm or more can be vertically cut into four or six valves.
Second, the forage part of the harvested grass is leaves and stems, which can be cut 4-5 times per year, and can be harvested 1-2 times in the year of planting. There are also differences in the period of castration using different days. It is used as green fodder and has a high yield from the bud to the flowering stage, and is rich in nutrients. It is suitable for harvesting; for the purpose of silage or preparation of hay, it should be cast in the full flowering stage. When the harvest is too late, the stems and leaves turn yellow and the stems become old. The yield and quality are both reduced, which also affects the yield of the next cut and reduces the number of cuts. The harvest is premature, the yield is low, the nutrient content is low, the total dry matter yield is low, and the roots accumulate less nutrients, which affects the regenerative capacity. Cut green should also be determined according to feeding objects: feed cattle, sheep, pigs, should cut old, feed chickens, ducks, geese, rabbits, ostriches, should be tender and tender. The harvesting height of the congregation grass has a great impact on the yield. Although the yield of the Liu lopped cuttings is high, it is slow to return to green and the output of the latter few crops is low. Too high to stay, serious loss of waste, generally stay 5-6 cm high. The last harvest should be completed 30 days before the stoppage of growth so that there will be enough regeneration period to facilitate the formation of good wintering shoots and safe wintering.
