Embodiment 1

[0008] (1) Test material

[0009] The experiment was carried out in the crop specimen garden of Yunnan Agricultural University from March to August 2002. The soil was red loam with medium fertility. The konjac cultivar "Mahua 15" was selected as the test material, and the average weight of each underground corm was 14.0g. When the local temperature stabilized above 15°C, it was sown on April 27, and 25 taro seeds were sown in each treatment, arranged in random blocks, and repeated three times. Three treatments were set up in the experiment: low-temperature refrigerated taro seeds, seeds soaked in chemicals and control. Low-temperature refrigerated taro treatment: Before sowing, place the taro in a refrigerator at 5°C for 30 days before sowing.

[0010] (2) Test method

[0011] Before sowing, dig the seeding ditch, and then every 667m 2 Apply 1500-2000kg of farm manure, 30kg of general calcium and 15kg of potassium sulfate as the base fertilizer, and mix well with the soil;...

Embodiment 2

[0019] (1) Test material

[0020] The Amorphophallus konjac "Chuhua No. 2" was selected as the test material. The size of the taro was the same, and the average weight of a single stem was 145 grams. The test chemicals were 72% agricultural streptomycin, soda ash, and lime powder.

[0021] (2) Test method

[0022] The experiment was carried out from April to December 2005 at the teaching experiment farm of Yunnan Agricultural University. Sowing on April 14, the test set 5 treatments, respectively agricultural streptomycin treatment: soak the seeds with 72% agricultural streptomycin 3000 times solution for 30 minutes before sowing, and spray the leaves with the same concentration of drug solution after emergence; soda ash treatment : Soak the seeds with 200 times of soda ash solution for 30 minutes before sowing, spray the leaves with the same concentration of medicinal solution after emergence; apply lime powder: use lime powder (50kg / 667m 2 ) in the sowing ditch, and sprink...

Embodiment 3

[0034] (1) Test material

[0035] "Chu Mohua No. 1" was selected as the test material, provided by the Konjac Research Institute of Yunnan Agricultural University. Select konjac bulbs with the same size, smooth skin, full and strong terminal buds, no damage, and no pests as seed taro, with an average single stem weight of 145g.

[0036] (2) Test time, place and test design

[0037] The experiment was carried out at the teaching experiment farm of the College of Agronomy and Biotechnology of Yunnan Agricultural University from March to December 2010. The soil was red loam with medium fertility. The experiment adopts random block arrangement, sets 4 treatments, repeats three times, a total of 12 plots, the plot length is 3m, width is 2m, and plot area is 6m 2 .

[0038] (3) Test method

[0039] Agricultural streptomycin treatment: Soak the seeds with 72% agricultural streptomycin 3000 times solution for 30 minutes before sowing, sow the seeds after the drug solution is dried...

Abstract

The invention relates to a method for preventing konjak soft rot, belonging to the technical field of plant protection. The method for preventing the konjak soft rot comprises the following steps of: before sowing, adjusting the temperature of a refrigerating chamber of a refrigerator to constant temperature of 5 DEG C, and then taking seed konjak in the refrigerating chamber and sowing after the seed konjak is refrigerated in the refrigerating chamber for 30 days. A konjak planting method and field management are regular methods. The method for preventing the konjak soft rot has the advantages of simple method, excellent disease control effect, high konjak yield and capability of reducing pollution of agricultural products and environment by chemical pesticides.

Description

Technical field: [0001] The invention relates to a method for preventing and treating konjac soft rot, which belongs to the technical field of plant protection. Background technique: [0002] Konjac (Amorphophalms konjac) is a perennial herbaceous plant of the genus Konjac in the family Araceae, also known as konjac. Underground tubers are rich in glucomannan, pectin, alkaloids, starch, ash, 17 kinds of amino acids and various trace elements. It has the effects of lowering blood fat, reducing the incidence of diabetes and colon cancer, and reducing weight. It is a kind of economic crop with high edible, medicinal, health care and industrial value. Konjac originated in India, the northern part of the Indochina Peninsula in Asia and the 16-24° north latitude in southern Yunnan. It belongs to the tropical rainforest climate zone, and its ancestor species is a herbaceous plant in the lower layer of the tropical forest. China's konjac medicine has a long history, and it has bee...
