Lotus root is a water lily plant lotus fat rhizome, taste slightly sweet and crisp, can be raw food can also do dishes, and medicinal value is quite high, its roots and leaves, flowers and fruits are not treasure, suitable for growth in the hot and rainy season, south of the Yangtze River more in March to early April planting, Beijing more in early May planting, the following we take a look at how to plant lotus seedling planting it!
A, lotus root cultivation conditions
1, temperature: lotus root at 15 ℃ above the seed root can sprout, the growth period requires a temperature of 20 ~ 30 ℃, the water temperature 21 ~ 25 ℃. The early stage of the lotus root requires a higher temperature, the later requires a greater temperature difference between day and night, the dormant period requires more than 5 ℃, less than 5 ℃ easy to freeze.
2, light: lotus root for light-loving plants, intolerant of shade, the reproductive period requires sufficient light, the length of the sunshine requirements are not strict, before the light is conducive to the growth of stems and leaves, the late light is favorable to the flowering, fruits, and lotus root body of the full.
3, water: lotus root sprouting growth stage of the water level of 5 to 10 cm is appropriate, the growth stage requires a water level of 30 to 50 cm, and later with the flowering of the plant, the results and lotus root water level is appropriate to gradually fall shallow, dormant overwintering only need to be sufficiently moist soil or keep shallow water.
4, soil: lotus root growth to rich organic matter loam and clay loam soil for the most suitable, the content of organic matter should be at least 1.5% or more, the soil pH requirements between 5.6 to 7.5 to 6.5 for the most suitable, the requirements of nitrogen, phosphorus, potassium and three elements.
Two, lotus root planting method
1, choose a good seed: seed root selection without injury or disease, good breeding, individual large, thatch head complete, tail tip complete, complete top and side buds, lotus root nodes, thick and full, early maturity and yield shallow lotus root varieties, and strive for uniform size.
2, fertilization of the whole field: choose fertile, deep mud layer, drainage and irrigation is convenient and the previous year planted rice field planting lotus root is better, 15 days before planting lotus root acres of rotting organic fertilizer 2000 to 3000 kg, 150 kg of cake fertilizer, calcium superphosphate 70 kg, lime 80 kg.
3, planting time: choose a sunny day afternoon first in the field will be arranged in accordance with the required spacing, and then according to the size of the body of the lotus root hand-dug trench planting, the front end of the lotus root slanting downward, the back end of the slightly exposed soil, is conducive to the acceptance of light and air, to promote the germination.
4, planting method: into the mud depth for the mud cover did not lotus root body and lotus root buds shall prevail, by the ridge around the ridge planting attention to all lotus root head to the heart of the field field flat mud when ditching or pond planting.
Three, lotus root field management
1, weeding and leaf removal: lotus root planting about a month after the floating leaves gradually withered when removing the dead leaves, combined with fertilizer weeding before sealing the rows, weeding should be in the roll of the leaves on both sides of the walk, the emergence of flower buds or bloom often bending the flowering branches but not picked off.
2, reasonable fertilizer: in 3 ~ 5 pieces of standing leaves mu Shi high nitrogen and phosphorus compound fertilizer 25 ~ 30 kg, in the field full of standing leaves mu Shi high nitrogen and potassium compound fertilizer 30 ~ 35 kg, in the termination of the leaf appeared mu Shi high potassium compound fertilizer 15 ~ 20 kg or wuye microbial fungicide.
3, adjust the water level: lotus root from planting to sprouting before irrigation shallow water about 5 ~ 10 cm, in order to improve the ground temperature, conducive to the emergence of seedlings, with the growth of the standing leaves and branches, gradually deepen the water layer to 15 ~ 20 cm, knot lotus root period and harvest before the preferred irrigation shallow water.
4, rationalize the head of the lotus root: lotus root in June when the lotus root vine grows rapidly to the surrounding area, to manually vine, in the middle of the day when planing the mud to pull up the lotus root vine, turn the head to the blank ground and then buried in the soil can be.
5, mature harvesting: most of the local upper leaves withered, the lotus root has been fully mature can be harvested one after another. Lotus root harvesting has green lotus root, withered lotus root points, green lotus root in August, the collection of withered lotus root after the fall to the next year in March to April.
