High quality pasture suitable for sowing in the north - Leymus chinensis
Leymus chinensis, also known as alkaloids, is one of the important building species on the meadow meadows and arid grasslands in the eastern Eurasia grasslands. Songnen Plain in the northeast of China and the eastern part of Inner Mongolia are its distribution centers and are also distributed in Hebei, Shanxi, Henan, Shaanxi, Ningxia, Gansu, Qinghai, and Xinjiang provinces (autonomous regions). Leymus chinensis is most suitable for planting in the northeast and north China provinces (autonomous regions), and it grows well in cold, dry areas. Spring returned to early morning and late autumn yellow, can provide more green feed in a longer period of time. First, economic value. L. chinensis leaves are abundant, nutrient-rich, and palatability is good. All kinds of livestock are fond of eating all year round, and they have the reputation of “fine grain for livestockâ€. Herdsmen describe it as saying: “Lycao has oily properties. When it is used to feed livestock, it is not fed or fed.†Before the flowering period, its crude protein content generally accounts for more than 11% of dry matter, and the period of confinement is as high as 18.53%. Rich in carotene content. Carbohydrate 49.5-85.87 mg per kilogram of dry matter. After L. chinensis is prepared into hay, the crude protein content can still be maintained at about 10%, and the smell is fragrant, the palatability is good, and it is resistant to storage. The yield of Leymus chinensis is high, and the potential for yield increase is large. Under good management conditions, it generally produces 3000-7500 kilograms of hay per hectare and produces 150-375 kilograms of seeds. L. chinensis has very strong penetrating ability and can form a strong root net. It is a very good soil and water conservation plant. The stalks of Leymus chinensis are also good papermaking raw materials. Second, characteristics. Leymus chinensis is a grass perennial herb. It has a well-developed underground rhizome, with a root depth of 1-1.5 m, and is mainly distributed in soil layers of more than 20 cm. Stems erect, sparsely plexiform, with 3-7 nodes, 50-100 cm tall. The leaves are thick and hard, flat or coiled, 7-19 cm long, grayish green or greyish blue-green. Leymus chinensis is cold-resistant, drought-resistant, salt-tolerant, and resistant to soil. It has a wide range of adaptation. Born in the open plains, rolling hills, riverbanks and saline lowlands. In the winter -40.5 °C can safely winter, grow well in areas with an annual rainfall of 250 mm. Leymus chinensis moist sand sandy chestnut soil and chernozem, can grow at pH 5.5-9.4, the optimum pH value of 6-8. It also grows well in poorly drained meadow soil, salinized soil, and alkalized soil. However, it is not resistant to flooding, and there will be a large number of deaths in the long term. Leymus chinensis in wet years, lush stems and leaves, often do not heading, dry years, grass high leafy, able to heading and fruiting. L. chinensis has developed rhizomes, latent shoots on rhizomes, and strong asexual regeneration ability. Early spring return to early morning, rapid growth, late fall dormancy, grass use a long time. Fertility period of up to 150 days. The growth period is up to 10-20 years. Third, cultivation techniques 1. Soil and cultivation: Leymus chinensis is selected in a lax way. It can be planted except for barren slopes and low-temperature lands. Soils with deep soil and high organic matter and sandy loam are the best. Requires good land preparation and good site preparation. Falling to the ground, the depth of more than 20 cm, immediately after the collapse and pressure ground. 3. Seed sowing: The seeds of L. chinensis must be selected before sowing, and the purity, cleanliness and germination rate of the seeds should be checked to meet the sowing quality standards. Leymus chinensis can be planted in spring, summer and autumn. Spring sowing should be sown in late March or early April. Summer sowing should be planted in late May or early June. Autumn sowing must not be later than late August. The sowing rate per hectare is 37.5-42.5 kg, the spacing is 15-30 cm, and the cover soil is 2-3 cm. After the sowing, the crackdown will be timely to facilitate the emergence of seedlings. Leymus chinensis is mixed with other crops such as alfalfa, sand savanna, and wild peas to increase its yield and quality as well as soil fertility. 4. Field management: The growth of Leymus chinensis during seedling stage is very slow and it is easily inhibited by weeds. Therefore, weeds must be eliminated promptly. The topdressing is to be carried out after rapid growth to rapid growth. Immediately after top dressing, water should be poured. After the L. chinensis grows to 5-6 years, it should be renewed to restore productivity. Fourth, the use of methods. Sheep grassland can be grazing, green feeding and silage, but it is mainly used for preparing hay. 1. Grazing: In mid-April, the height of the plant is about 30 centimeters after grazing, and after the heading in mid-June, the texture is rough and the palatability is reduced. Grazing should be stopped. Grazing sheep, cattle, and horses are usually used, and pigs and geese can be grazing during the young period. It is necessary to designate the area for animal husbandry and to prevent the replay of animal husbandry. Each grazing can be about 1/3 of the total output. It is also possible to use grazing cows, sheep and horses in the winter. 2, modulation of hay: From booting to initial flowering, the roots of the accumulation of more nutritious period of time. After drying for one day after cutting, pile up a small pile of loose and loose, and slowly dry it. When the moisture content drops to about 16%, you can integrate large piles and prepare to transport it back to storage. Green Larch Hay, a cow can feed 15-20 kilograms a day. Short cut or whole feed is good. Leymus chinensis hay can also be made into grass powder or grass granules, grass blocks, straw bricks, and grass cakes for commercial forage.

2. Fertilization: Leymus chinensis has a long service life, fast growth, high yield, and a lot of fertilizer. It must apply enough basic fertilizer and timely fertilizer. The semi-mature heaps and manures of basal manure are 3.7-45 thousand kilograms per hectare. The addition of phosphate fertilizer and boron fertilizer can also increase the seed-setting rate, increase the seed yield and improve the seed quality.
