Problems solved by technology

At present, Mianlong has been widely used in the prevention and control of soil-borne diseases of strawberry, watermelon, tomato, cucumber and other crops, but many years of application have exposed the same problem, that is, when the soil temperature is lower than 15 ℃ , the soil disinfection effect in Mianlong is very poor ("Key Points for Using Soil Disinfection in Mianlong", Wu Renfeng, Hubei Plant Protection, 2012), not only the killing rate of pathogenic bacteria is low, but also some bactericidal substances that have not been decomposed and left are likely to cause phytotoxicity to crops
This situation is most obvious in watermelons, because after the establishment of greenhouses and solar greenhouses, in order to gain higher economic income in advance, the current watermelons have been planted in January and February in advance, and at this time

Embodiment 1

[0023] Example 1 Inhibitory test of melon on mycelia growth of Fusarium wilt of watermelon

[0024] Watermelon Fusarium wilt was inoculated into a PDA plate, cultured at 28-30° C. for 5 days, and then punched with a hole punch to obtain mycelial blocks with a diameter of 4 mm for future use.

[0025] Inoculate a mycelium block with a diameter of 5 mm in the middle of the PDA plate medium, add 0.01 g, 0.015 g, 0.02 g, 0.025 g, and 0.03 g of cotton wool to the center of the petri dish (8.5 cm in diameter) respectively, and sterile The water was quickly mixed at a mass ratio of 1:1, and each treatment was repeated 3 times. At the same time, a control group (without adding cotton wool) was set up; then the half of the culture dish inoculated with the mycelium block was buckled upside down on the lid of the culture dish, and sealed with a parafilm. Sealed, cultured at a constant temperature of 28°C, after 72 hours the culture results were as follows: figure 1 As shown, the colony ...

Embodiment 2

[0028] Example 2 The killing effect of Mironon on the watermelon wilt bacteria in the soil in the facility greenhouse

[0029] The experiment was carried out in Huai'an City watermelon continuous cropping greenhouse, where watermelon has been continuously cropped for many years, and Fusarium wilt occurred seriously. The area of ​​the greenhouse is 8 meters (width) * 40 meters (length), and the experiment is divided into two groups:

[0030] 1. The control group, without any treatment;

[0031] 2. Cotton treatment group, cotton fumigation;

[0032] Each group has 3 plots, each with an area of ​​22 square meters (2.2 meters wide and 10 meters long).

[0033] The test operation is as follows: in the first year, from the end of May to the middle of June, the watermelon residues planted in the spring stubble in the greenhouse were removed, and 20 kg of commercial organic fertilizer and 2 kg of NPK compound fertilizer (15-15-15 ), the soil is rotary tilled 20-25 cm deep;

[0034...

Embodiment 3

[0038] Example 3 The reduction effect of planting garlic in autumn on the number of watermelon wilt bacteria in the soil after soil disinfection and the prevention and control effect on the occurrence of watermelon wilt in spring

[0039] The test was carried out in the greenhouses of the control group and the cotton wool treatment group in Example 2.

[0040] In mid-to-late September, garlic was planted and managed by conventional methods in the control group and in the plots that were air-dried for 3-4 days after cotton-long disinfection treatment (for specific management methods, please refer to the literature "Planting and Management of Garlic", Li Chunmei, Farmers Get Rich Friends, 2016).

[0041] Garlic seedlings are harvested from the end of January to the middle and late February of the second year. After the garlic harvest is over, soil samples are collected in each plot according to the S-type soil extraction method, and the selective medium is used to count the bact...

Abstract

The invention relates to the field of prevention and control of crop soil-borne diseases, in particular to a method for shortening a rotation cycle of a watermelon and preventing and controlling fusarium wilt of the watermelon. The method comprises the steps: cleaning a plant residue after a spring watermelon is harvested, applying a fertilizer, performing rotary tillage on soil, broadcasting dazomet, performing the rotary tillage on the soil, performing watering, covering a plastic film for 10-15 days, removing the film, performing sun curing, sterilizing the soil, planting a liliaceae crop with a root system capable of secreting an irritant and bacteriocidal substance in the sterilized soil in autumn, and planting the watermelon again to complete the rotation cycle of the watermelon. The method adopts the dazomet to sterilize the soil planted with the spring watermelon in summer, so that fusarium wilt bacteria of the watermelon in the soil can be killed to the greatest extent; the liliaceae crop capable of killing the fusarium wilt bacteria of the watermelon is planted in the autumn, so that the quantity of pathogenic bacteria is further reduced; and in addition, vegetable crops are continued to be planted in a greenhouse in the autumn, so that income is increased, and the whole prevention and control method is simple in process and easy to operate, and meets an actual demand of agricultural production.

Description

technical field [0001] The invention relates to the field of prevention and control of soil-borne diseases of crops, in particular to a method for preventing and controlling watermelon wilt by shortening the rotation period of watermelons. Background technique [0002] Watermelon is a popular fruit. The average area of ​​watermelon planted in my country is 17 million mu every year, ranking first in the world. With the continuous expansion of planting area and continuous cropping, the occurrence of watermelon wilt has become more and more common and serious, and it has become one of the most devastating soil-borne fungal diseases in the world. The pathogen of the disease is Fusarium oxysporumf. sp. niveum FON, which can be used in various forms such as hyphae, conidia, chlamydospores and sclerotia, etc. Overwinter in stumps, seeds, and soil, and can survive for 5-6 years without the host. A small number of pathogens can even survive for more than 10 years. They are generally...
