Our country has a vast territory and a vast area, and the adaptability of soil, climate and pasture is quite different. Therefore, different planting patterns should be selected for the cultivation of high-quality forage grass: 1. Paddy-upland rotation areas: Suitable for autumn-sowing cold-season-type annual pastures or forage-green manure varieties, turning rice--wheat to rice--grass, optional species Flower ryegrass, winter grazing 70 rye, milk vetch, gardenia, arrow peas, etc.; can also be used for feed crops and pasture rotation, or forage and pasture rotation, spring should use feed corn, hybrid Pennisetum, America Pennisetum, Sudan grass, bitter vegetables, grain pods, etc.; autumn sowing should use more ryegrass, winter grazing 70 rye, feed cabbage, carrots, Gan Lan, etc.; can also be planted perennial grass. 2. Dryland rotation area: In the Huang-Huai-Hai plain area and other dry areas at the same latitudes, the variable wheat--corn is wheat-grazing or pasture--corn or pasture--herb, and perennial grasses can also be planted. Suitable varieties are mainly winter grazing 70 rye, forage corn, Pennisetum americana, Bitterweed vegetables, grain pods, hairy wolfberry fruit, grass hibiscus, arrow tongue peas. Sandy soils and saline-alkali soils should be developed with more developed root systems and more salt-tolerant varieties. Alkaline soil should use alfalfa, grass rake, sand wang. Acidic soil should use red clover and white clover, and regions with better soil conditions should promote Russian forage, Rumex K-1 hybrids, hybrid iris, schisandra, chicory and so on. 3, economic forest area: can use young Lin, fruit, tea, mulberry intercropping shade forage legumes, dwarf grass or green manure, should use varieties of chicory, Rumex K-1 hybrids, alfalfa, Red clover, white clover, wolfberry fruit, grass hibiscus, sand wang and so on. 4. Hilly areas: high-yield, high-quality varieties should be introduced, and grassy hills and grass slopes should be improved in large areas in order to increase the yield and quality of fresh grass. The south should use heat-resistant, tolerant, and well-covered perennial forage grasses and grass species such as purple flowers. Grasshoppers, clover, tall fescue, bluegrass, and Bahia grass are the best for mixed legumes and leguminous plants; cold, drought-tolerant, and good-coverage pasture varieties should be used in the north. 5, tidal flat area; in the intertidal zone should be planted rice grass, Spartina alterniflora; saline and alkaline land should be planted alfalfa, grass hibiscus, sand and other Leguminous pasture grass and multi-flower ryegrass, Festuca, Bromus, etc. For grasses, high-yielding forage grasses such as Russian feed, Rumex K-1 hybrids, Schizonepera, and Pennisetum can be cultivated in areas with good soil conditions. 6, plateau alpine areas: the area is mostly a collection, it is appropriate to promote the cold-resistant Russian feed dish, Rumex K-1 hybrids Sorbus, pine cone herb, alfalfa and so on. For high-quality forage grass cultivation, full utilization of grain, poor planting time, and conditions of light, heat, water, and soil resources should be used to achieve high yield and high efficiency. After practical exploration, the author specifically recommended the following kinds of planting methods to the readers: 1. Cold and warm hay rotation. In the autumn, annual rye is planted. After the end of rye, it is planted with Pennisetum americana. After the Pennisetum americana is planted, annual rye is planted. This cycle will ensure the balanced supply of green grass throughout the year. In the Huaihe River Basin and in areas south of the rye, multiple ryegrass or winter grazing 70 rye can be used, and in the area north of the Yellow River, Dongmu 70 rye should be used. 2. Crossbreeding and perennial intercropping. Most perennial pastures begin to wither at the end of September and enter the luxuriant period in April of the next year. The row spacing of Rumex K-1 hybrids, Russian forage dishes, pine-leaf herbs, and hybrid pennisetum are all above 0.5 meters, and newer annual pastures can be interplanted, such as ryegrass, rye 70, and rye. , such as hairy seedlings, generally sowed in early October and used in early April of the following year. This model can effectively use light and heat and land resources, solve the shortage of winter and spring grass, and ensure a balanced supply of pasture. 3, fruit grass interplanting. Most of the orchards fall before and after October and germinate in April of the following year. In the beginning of October, we can plant new species of pasture and use it in April of the following year. The principle of this model is intertwined with the more recent and perennial grasses. Young trees can be planted mainly between young trees. 4, three wheat and pasture rotation. Sanmaiduo is harvested before the end of May to mid-June. After the harvest, it can be planted with Pennisetum americana and Sudan grass. In order to promote early onset of pastures, advancement of seedlings can be carried out on pasture varieties with large rows and spacings, and wheat transplants should be transplanted immediately after harvest. Wheat can be grown after harvesting. 5, dishes, grass rotation. Most wintering vegetables are harvested before the beginning of May, and pasture can be planted after harvest. 6, winter free field grass. Cotton, spring sweet potato, etc. are all planted before and after the beginning of summer, and the winter-free fields can be used to plant the annual pasture. 7, wheatgrass rotation. Can reserve space in the wheat seedlings, planting Pennisetum or Sudan grass and so on. 8, pasture and corn rotation. New years old pastures are planted, summer corn is planted after harvesting, and pastures are planted after corn is harvested. 9, grass rice rotation. After the early rice is harvested, the Gaoxiangshangou drains moisture, and then grows warm and annual pastures. It is also possible to plant the new year-old pasture after the late rice harvest, and the late rice planted after the harvest. 10. Sparsely plant grass. In our country's vast agricultural areas, there are large areas of slopes, ponds, roadsides, river slopes, embankments, ditches and crevices. Pastures can be planted all year round. Due to poor water and fertilizer conditions, drought- and drought-tolerant varieties can be used. Planting. 11, Liang Tian good soil grass all year round. In large agricultural areas, about one-third of the fields can be vacated for planting pastures. In the varieties, it is necessary to choose the high-quality, high-quality pasture varieties introduced by the author. Otherwise, it is not worth the candle. 12, before the house, behind the house, garden grass. Because of the short distance, it is more convenient to use. After planting grass, it is recommended to use germ-resistant varieties.
