The è¸è alias glutinous rice, horseshoe, etc., is a perennial shallow water herb of the sedge family. It is cultivated in all provinces and regions south of the Yangtze River. It has an area of ​​about 200 hm2 per year in Anxiang County, Hunan Province. It is the main characteristic aquatic vegetable of the county. one.è¸è Using underground stems to grow new plants for breeding, the breeding methods include high-density seedlings and sparse planting. First, high-density nursery 1) Features. It has a large amount of seeds, a short seedling age, and convenient management in the seedling stage. The seedbed can use the air gap and does not need to occupy rice fields. 2) Method. High-density seedlings are generally carried out 20 to 25 days before transplanting, and the seedling age is no more than 30 days. The specific seedling time depends on the previous harvest. The former is early rice, and it is generally arranged to raise seedlings before and after the small heat. The former is the early breeding of safflower seeds. Before raising seedlings, you must first choose a good seedbed. The seedling bed should be selected under the shade of trees or under the shade of the melon shed for the purpose of sheltering the sun. The open space behind the house can also be used as a seedbed, but it must be shaded with straw or branches and fenced. Keep out to prevent chickens, ducks, geese and other poultry and livestock from being trampled. The seedbed should be leveled, the subsoil should not leak, and the seedbed should be 100-130cm wide. The length can be determined by the topography and the seeding rate. A small levee 10-15 cm high is built around the seedbed, and no soil is needed in the bed. After the whole seedbed is in place, it can be seeded. It should be noted that the seed shape is perfect, the single large and uniform, no pests and diseases, no one is a healthy cockroach for mechanical trauma. The selected alfalfa species can be directly placed in the seedbed, or they can be germinated and planted first. The method of germination is: soak the scorpion in clear water for 2 to 3 days and nights, then put it into the basket, immerse it 3 to 5 times a day, keep it moist, and wait until the buds sprout and white. The amount of seed used per field of 667m2 is 65-70kg, and the amount of single bulb is large, and the amount of seed is small. The seeding starts from one end of the seedbed, one close to the other, but the bulbs cannot overlap each other, the seed buds face upwards, and the flattening can be stabilized. After finishing the ball, cover with a layer of fine loess or sifted fertile garden soil, the thickness can be submerged in the dome. If you can cover a layer of fire ash mixed with farmyard manure, it is more conducive to cultivating strong seedlings. After seeding, the seedbed should be filled regularly to keep it moist, to prevent water from drowning, and to be careful when filling the water. Do not wash off the fine soil on the bulb. 5 to 7 days before seedling transplanting, the shed refining seedlings were gradually uncovered to adapt to the high temperature and strong light environment. This kind of seedling method is short in seedling age, and the seedlings can grow by absorbing the nutrients in the bulb, and no fertilizer is needed, but the whole seedling stage should pay attention to prevent rats and sparrows from harming. Second, rare planting seedlings 1) Features. This method is also called ramets propagation. It is characterized by long seedling age, low seed consumption and low cost. Especially when introducing a small number of new varieties, this method can be used to breed a large number of species using smaller bulbs. seedling. 2) Method. Rare planting seedlings should choose paddy fields with moderate muddy feet, fertile soil, and good irrigation and drainage conditions. Before planting the seedlings and planting the fields, the land preparation should be carried out, and the ground fertilizer should be applied in combination with the ground preparation for the growth of seedlings. According to the dense planting method described above, when the seedlings are cultivated to a height of 40 to 60 cm, they are transferred to a pre-flattened field for breeding. The plant spacing can be 150 to 180 cm, and each planting is 1 plant. After shedding, the plants are still transplanted to the field to supply nutrients. After 3 to 5 days, the seedlings were re-greened, and new tillers were formed, and the new plants were planted. The lateral buds of the new plants were extracted from the stalks. After the stalks grew to 10-15 cm, the top buds of the succulent stems sprouted upwards and formed leafy stalks. In the same way, the ramets and the ramets are branched and tillered to form a plexus. The speed of ramets is related to factors such as fertilizer and temperature. The fertilizer is sufficient. When the temperature is between 25 °C and 30 °C, the ramets occur fastest. One ramets can be sent for about 10-15 days. The new plants formed in Putian can be transplanted to the field as a single plant, but attention should be paid not to damage the seedlings when taking the seedlings. The above is the whole content of the key technologies of aquatic vegetable seedlings.
