What are the techniques for growing early-maturing lotus root? What methods can make lotus root mature early? We also ask experienced netizens to help introduce them.Zhongdiwang has compiled several key techniques for making lotus root mature early, listed below for netizens' reference.
Method 1: Select excellent lotus root seed stock:
Choose shallow-layer lotus root varieties that are undamaged and disease-free, with good varietal characteristics, large individual size, intact growing tips, complete tail shoots, complete terminal buds and lateral buds, and thick, plump rhizome nodes, and that are early-maturing and high-yielding as seed stock, and try to make them uniform in size.
Method 2: Choose a good lotus root field and apply sufficient base fertilizer:
It is better to choose fertile fields with a relatively deep mud layer and convenient drainage and irrigation, and where rice was planted the previous year, for planting lotus root. 15 days before planting lotus root, apply 2000-3000 kg of decomposed organic fertilizer, 150 kg of cake fertilizer, 70 kg of superphosphate, and 80 kg of quicklime per mu. After fertilizing, deep plow, finely level, and rake the lotus root field smooth, and maintain a water layer 3-5 cm deep.
Method 3: Planting density of early-maturing lotus root:
Early-maturing cultivation generally requires a somewhat higher lotus root planting density, with a seed quantity of 250-300 kg per mu, a plant-to-row spacing of 0.8 x 1.8 m, and a requirement of 300-400 buds per mu.
Method 4: Planting method for early-maturing lotus root:
Plant according to the above plant-to-row spacing. Plants between rows should be arranged in a plum-blossom pattern. For lotus root planted around the field edges, the buds should face inward, and the bud direction of the remaining rows should also be consistent. When planting, insert the buds into the mud, with the tail shoots sticking out above the water surface.
Method 5: Management methods for early-maturing lotus root:
Management of lotus root in the early planting stage:
This stage is mainly to promote the formation and growth of floating leaves. Water should be managed well, preferably maintaining a water layer 5-10 cm deep, and keeping the soil in a soft muddy state. On sunny days with high temperatures, ventilation should be carried out promptly to prevent scorching the lotus leaves. After mid-to-late April, when the temperature stabilizes at around 20°C and the arched shed is full of lotus leaves, the film can be removed and the arch withdrawn, the lotus root field water should be filled to 10-15 cm, and 1000 kg of human and livestock manure and 15 kg of urea should be applied per mu.
Management of lotus root in the middle planting stage:
Generally in mid-to-late May, weeds are pulled by hand once. After pulling weeds, in order to make the lotus root distribute evenly in the field, the growth direction of the lotus runners should be adjusted in time, and the lotus runners should be prevented from growing into the field ridges. At this stage, 20 kg of compound fertilizer and 10 kg of urea should also be applied per mu as topdressing.
Diseases that lotus root needs to be protected against:
The main one is lotus leaf soft rot. The water quality should be kept clean, diseased leaves should be removed in time, and 70% thiophanate-methyl 800-1000 times solution should be sprayed once every 10 days.
Harvesting of early-maturing lotus root:
Early-maturing lotus root is generally harvested in batches in late June, when the lotus root has grown to 3 nodes, and the harvest time can generally be about 20 days earlier than conventional cultivation. When harvesting, be careful not to damage other lotus roots.
