Embodiment 1

[0009] A method for preventing and treating Fusarium wilt of watermelon, comprising the following steps: (1) selecting disease-resistant varieties or adopting grafting technology, and implementing multi-year crop rotation, preferably, the crop rotation time is 6 years. (2) Reasonable fertilization: apply decomposed organic fertilizers, increase phosphorus and potassium fertilizers, promote plant robustness, and prevent vigorous growth; (3) High-temperature stuffy shed: Before planting watermelons, keep the shed temperature at about 45°C. Soil humidity, if the soil is dry, water once a day before treatment; (4) Soil treatment: When preparing the soil, use 500 g / mu of pentachloronitrobenzene, mix with 5 kg of fine sand to spread evenly and turn the soil , Disinfect the soil, and transplant after 30 days; (5) During the planting period or before the onset of the disease, use 10ml of Chongzhubao + 25ml of Genbao + 15ml of Youfeng mixed with 25kg of water to irrigate a single plant ...

Embodiment 2

[0011] A watermelon fusarium wilt prevention method comprises the following steps: (1) selecting disease-resistant varieties or adopting grafting technology, and implementing multi-year crop rotation, preferably, the crop rotation time is 8 years. (2) Reasonable fertilization: apply decomposed organic fertilizers, increase phosphorus and potassium fertilizers, promote plant robustness, and prevent vigorous growth; (3) High-temperature stuffy shed: Before planting watermelons, keep the shed temperature at about 45°C. Soil humidity, if the soil is dry, water once a day before treatment; (4) Soil treatment: When preparing the soil, use 1000 g / mu of pentachloronitrobenzene, mix with 10 kg of fine sand to spread evenly and turn the soil , Disinfect the soil, and transplant after 30 days; (5) During the planting period or before the onset of the disease, use 10ml of Chongzhubao + 25ml of Genbao + 15ml of Youfeng mixed with 25kg of water to irrigate a single plant for prevention.

Embodiment 3

[0013] A watermelon fusarium wilt prevention method comprises the following steps: (1) selecting disease-resistant varieties or adopting grafting technology, and implementing multi-year crop rotation, preferably, the crop rotation time is 7 years. (2) Reasonable fertilization: apply decomposed organic fertilizers, increase phosphorus and potassium fertilizers, promote plant robustness, and prevent vigorous growth; (3) High-temperature stuffy shed: Before planting watermelons, keep the shed temperature at about 45°C. Soil humidity, if the soil is dry, it can be watered once a day before treatment; (4) Soil treatment: When preparing the soil, 800 g / mu of pentachloronitrobenzene can be used, mixed with 8 kg of fine sand to spread evenly and turn the soil , Disinfect the soil, and transplant after 30 days; (5) During the planting period or before the onset of the disease, use 10ml of Chongzhubao + 25ml of Genbao + 15ml of Youfeng mixed with 25kg of water to irrigate a single plant ...

Abstract

The invention discloses a watermelon fusarium wilt preventing and controlling method. The method comprises the following steps of 1, selecting disease-resistant varieties or adopting a grafting technology to achieve multi-year crop rotation; 2, reasonably applying fertilizer, wherein decomposed organic fertilizer is applied, and phosphorus potassium fertilizer is additionally applied; 3, conducting high-temperature close greenhouse treatment, wherein before watermelons are planted, the greenhouse temperature is maintained around 45 DEG C, and if soil is dried, watering can be conducted once one day before treatment; 4, conducting soil treatment, wherein before land preparation, 500-1,000 g of quintozene can be applied per mu, 5-10 kg of fine sandy soil is mixed to be uniformly sprayed andturned, and transplanting is conducted 30 days later; 5, before field planting or invasion of diseases, using 10 ml of continuous cropping agent, 25 ml of genbao, and 15 ml of Youfeng, and adding 25 kg of water to water every single plant. By means of the watermelon fusarium wilt preventing and controlling method, the occurrence of watermelon fusarium wilt can be reduced, so that the yield of thewatermelons is not reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for preventing and curing watermelon wilt. Background technique [0002] Fusarium wilt, commonly known as dead seedling disease, is one of the common fungal diseases of watermelon. It mainly damages the vascular bundles of watermelon. It can occur from seedlings to fruit maturity, and the disease is more serious in the fruiting stage. When the occurrence of watermelon wilt is serious, the yield can be reduced by more than 50%, or even no harvest, which greatly reduces the yield of watermelon and affects economic benefits. Contents of the invention [0003] The purpose of the present invention is to provide a watermelon wilt control method, which can reduce the occurrence of watermelon wilt so that the output of watermelon is not reduced. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: a watermelon f...
