There are many varieties of lotus root seedlings, such as Yugoslavia Snow Lotus, Thailand Huaqilian, Erian No.5 (3735 Lotus Root), Erian No.9 (Big Mac Lotus Root), Big Purple Lotus Root (Red Bud Lotus Root), Floating Lotus Root, White Lotus Root and Fenghe No.1 Lotus Root. In shallow water, you can choose Erian series, Yugoslav snow lotus root, Thai Citigroup lotus root and floating lotus root, and in deep water, you can choose Yugoslav snow lotus root and white lotus root. In addition to the selection of varieties, the selection of lotus root breeding units is also very important. It is necessary to choose lotus root seedlings produced by regular lotus root breeding units, and at the same time, strictly disinfect lotus root seedlings during planting to avoid bringing in miscellaneous bacteria.
2. How many lotus root seedlings are needed for an acre of land
According to the different harvesting methods, lotus root seedlings can be divided into two ways: high-pressure water gun washing and digging and manual shovel digging. The former is quick to dig but easy to damage the epidermis and bud tip of lotus root, and its germination rate is lower than that of manual shovel digging, so 3% more lotus root seedlings should be planted than the latter. Under normal circumstances, an acre of land needs 5~6 kg of lotus root seedlings, and 7~8 kg is needed when the lotus root seedlings are washed with high-pressure water guns. In addition, according to the variety of lotus root, water quality soil and climate environment, the lotus root seedlings required for one mu of land will be different. For example, the lotus root varieties with large weight per plant and high yield per mu need more lotus root seedlings, and the lotus root seedlings are also needed when the water quality soil is not ideal or the climate environment is poor.
3. How much is a kilo of lotus root seedlings
The market price of lotus root seedlings varies slightly according to varieties and production units. The price of lotus root seedlings in the market is generally 1.5~3 yuan/kg, and the price of high-yield lotus root seedlings and lotus root seedlings dug by artificial shovel is more expensive. On the contrary, the price of lotus root seedlings with low yield and poor quality or lotus root seedlings washed by high-pressure water guns is cheaper, with an average price of about 2~2.2 yuan/kg. According to the calculation of planting 5 kilograms of lotus root seedlings on an acre of land, the cost of purchasing lotus root seedlings alone will reach 1~11 yuan.
4. Planting time and method of lotus root seedlings
Lotus root seedlings are usually planted after the spring, that is, from March to May every year. Planting can be started in the middle and late February as early as in the south, but not later than mid-May at the latest, because if the time is too late, lotus root seedlings will start to grow forward and grow lotus roots, which are tender and easy to be damaged, which will greatly reduce the germination rate. When planting, it is necessary to calculate the number of plants to be planted in an acre of land according to the size of lotus root seedlings, and the row spacing is generally 1.8~2 meters. Then, the plant spacing is calculated based on the above two data, and a small ditch with a depth of 5 cm is dug to put the tips of lotus root seedlings into the side and then gently cultivated with soil. After planting, put in 1~2 cm of water, and the lotus root seedlings will begin to take root and grow the first floating leaves in 3~5 days when the temperature is suitable.
