Background
Pennisetum sinese Roxb (Pennisetum sinese Roxb) is a perennial upright bush gramineae, also called as grain bamboo grass, king bamboo, elephant grass and sugarcane grass, has strong tillering capability, and can tillere 80-90 plants per year by a single plant, which is called as emperor in the grass. Its leaves are tall and stem, like the petunia, so it is named "Huangzhu grass". Pennisetum hydridum is bred by hybridization of pennisetum purpureum and pennisetum americanum, and is a novel efficient economic crop. Can be planted in most regions of the whole country, and is particularly better in barren mountains and river basins in middle and upstream regions of Yangtze river. The specific requirements are that the sunshine time is more than 1000 hours, the altitude is 200-1500 m, the average annual temperature is more than 15 ℃, the annual rainfall is more than 1000 mm, the annual frost-free period is about 250 days, the water source is sufficient during the seedling culture period, and the soil is sandy soil or loam which is deep and fertile. It has strong drought resistance and weak waterlogging resistance. It can resist low temperature and frost, but not frost. The fertility reaction to soil is rapid, and cow dung is the best fertilizer. Pennisetum hydridum is mainly subjected to vegetative propagation, and can be propagated by buds as long as the knots have buds. The pennisetum hydridum is mainly used for feeding animals, treating malignant weeds, and is used for environmental protection, water and soil conservation, building materials, frame materials, mushroom materials, beverages, fuels, paper pulp materials and the like.
In order to meet the requirements of industries such as continuously developed animal forage grass, treatment of malignant weeds, environmental protection, water and soil conservation, building materials, frame materials, fungus materials, beverages, fuels, paper pulp materials and the like on pennisetum hydridum seedlings and raw materials, the enlargement of the cultivation and planting of pennisetum hydridum becomes the urgent priority of the relevant industrial development of pennisetum hydridum, and the production supply technology and the supply capacity of high-quality pennisetum hydridum seedlings become one of the bottlenecks of the industrial development. The pennisetum hydridum can be used for seedling production in various modes such as root-stem separated seedling, root-stem overwintering seedling, seed-node seedling and the like, and the propagation coefficient of the root-stem separated seedling is low and is generally 1: about 5, the operation process of the root-dividing seedling culture is complicated, the labor intensity is high, and the method is only suitable for resource preservation and small-amount propagation; the propagation coefficient of the overwintering seedling raising of the stump seeds is only 1: 5-10, and is generally only used for a seed section production base or a fixed raw material production base. Both methods can not meet the requirement of large-area planting of pennisetum hydridum on high-quality seedlings of pennisetum hydridum. In order to stabilize and expand the pennisetum hydridum planting base and produce pennisetum hydridum seedlings with high quality and high price, a seedling control and seedling method which is most suitable for pennisetum hydridum seedling production must be adopted, and the propagation coefficient is 1: 75-150. However, the traditional pennisetum hydridum seed section seedling raising method is completed in soil of a field or a nursery base, the operation process is complex, the environmental conditions are difficult to control, underground pests are serious, the seed section loss rate is high, the seedling rate is low, the transportation is inconvenient, time and labor are wasted, the ratio of a seedbed to the field is high, the cost price is high, the quality cannot be guaranteed, and the rapid and healthy development of pennisetum hydridum industry is limited.

Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications can be made by those skilled in the art after reading the description of the present invention, and such equivalents also fall within the scope of the invention.
Examples
The pennisetum vegetative propagation crop utilizes stem node propagation. In order to ensure the emergence rate of the stem nodes, the method of firstly growing seedlings and then transplanting is adopted for cultivation. And (5) growing seedlings in 2-5 months. Seeding and raising seedlings when the temperature reaches above 15 ℃. When the temperature is low, the seedlings can be cultivated by covering plastic films on an arched shed for heat preservation, and the seedlings can be cultivated at any time all the year round.
A seedling raising method of pennisetum hydridum comprises the following steps:
1. selection of plant
Mature plants with the age of more than 6 months are selected from a pennisetum hydridum seed (node) propagation field as seed node collection plants, the axillary buds of the basal stem nodes are plump, the stems are dark brown, the internode length is gradually and uniformly lengthened from bottom to top, the axillary buds of the bud nodes are wrapped with green brown leaves, the growth is strong but not overgrown, and each plant can use more than 15 nodes. Later tillers (immature plants under 6 months old) which are tender and have axillary buds with green leaves around the collected seed plants of the seed nodes are removed. Firstly cutting off the seed section collection strains from the base part, cutting off the top tip part of the green color and the transverse unfolding part of the axillary bud envelope leaf of the seed section, reserving leaves of 50 cm on the stem tip, classifying the seed section collection strains according to the stem and the seed section length, and bundling 25-50 strains.
2. Overwintering management
(1) Digging pit for preserving overwintering
Selecting higher topography (underground water level is lower than 200 cm), digging deep 150 cm, then paving 10 cm-thick straw, putting 25-50 pieces of the pennisetum hydridum without stripping leaves and leaving tips into the pits, and filling 10-15 bundles into each pit. If the weather is too dry and needs to be drenched when the pit is filled, the soil is covered by 20-30 cm or the plastic film is covered by 20-30 cm, the storage temperature is controlled to be 10-12 ℃, and the cut soil is excavated and planted 3 months in the next year.
Covering with hay and crushed soil. The covering hay has the functions of keeping warm, absorbing moisture, maintaining the temperature in the cellar, and preventing broken soil from falling onto the stems. The method and the sequence are that 3-5 cm of dry straw is covered on the stacked stems, 5-10 cm of ground soil is covered from two sides to the middle after the dry straw is uniformly covered, and the thickness of the soil covering is determined according to the temperature. Areas with serious frost can be covered by thick straw, or the area can be thin, and the inserted breathable straw is required to be exposed and covered by 30-40 cm for ventilation. And drainage ditches are built around the pit to prevent rainwater from flowing into the pit.
