Embodiment Construction

[0010] The invention discloses a method for preventing and treating lotus root rotten disease. The specific steps are as follows:

[0011] Step 1: before sowing the lotus root, use 50% carbendazim 400 times solution to soak the lotus root seeds for 24 hours;

[0012] Step 2: After planting, spread quicklime evenly on the lotus root field according to the standard of 50kg / mu. After spreading, water the lotus root. In the early stage of lotus root growth, fill shallow water with a depth of 5cm. When the lotus root grows to the middle stage, Gradually increase the water depth to 15cm;

[0013] Step 3: Spray the mixture of 50% thiophanate-methyl 800 times solution and 75 chlorothalonil 600 times solution on the whole field in July. The two agents are mixed at 1:1, sprayed once every 5 days, and sprayed continuously for 4 days. Second-rate;

[0014] Step 4: When rot is found, use 50% succinic acid copper wettable powder 400 times liquid to spray evenly for treatment, and spray on...

Abstract

The invention discloses a prevention and treatment method for a lotus rhizome rot disease. The prevention and treatment method comprises the following concrete steps: step 1, before lotus rhizome seeds are sowed, subjecting the lotus rhizome seeds to soaking in a selected 400-fold carbendazim diluent with a concentration of 50%; step 2, after the soaked lotus rhizome seeds are sowed, uniformly spreading quick lime with a standard of 50 kg / mu into a lotus rhizome field, after the quick lime is spread, watering the lotus rhizome, irrigating shallow water with a proper depth of 5 cm in the early growth period of the lotus rhizome, and when the lotus rhizome grows to the middle period, gradually adding water until the water depth is 15 cm; step 3, carrying out full-field spraying with a mixed solution of an 800-fold thiophanate methyl diluent with a concentration of 50% and a 600-fold chlorothalonil diluent with a concentration of 75% in July; and step 4, when the occurrence of the rot disease is discovered, carrying out treatment by uniformly spraying a 400-fold DT wettable powder diluent with a concentration of 50%. With the prevention and treatment method for the lotus rhizome rot disease disclosed by the invention, the depth of a water layer is controlled according to different phases of the lotus rhizome; meanwhile, the enhancement of spraying a fungicide in a peak period of incidence effectively prevents the lotus rhizome rot disease and improves the yield of the lotus rhizome.

Description

technical field [0001] The invention relates to a method for preventing and treating lotus root rot, which is applied in the technical field of lotus root planting. Background technique [0002] Lotus root rot is caused by the infection of the fungus Fusarium rhizomes. The fungus survives the winter in the soil as mycelium along with the diseased residue. The fungus invades from the wound of the underground stem and the mycelium spreads in the stem. Ultimately, the aboveground blades and petioles die, which brings great distress to lotus root farmers. At present, there is no systematic way in the market to prevent and treat rot, which brings significant losses to the economic benefits of farmers. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a method for preventing and treating spoilage disease of lotus root, which can prevent the breeding of spoilage disease in advance and greatly improve the economic benefits of ...
