Abstract

The invention relates to a nontoxic non-residual soil processing and biological organic fertilizer combination method for preventing and controlling cucumber fusarium wilt, and belongs to an agricultural intensive production technology. According to the method, liquid ammonia is utilized for fumigating and disturbing the original soil microbiologic population, and special bio-organic fertilizers are combined and applied, so the number of beneficial bacteria in the soil is increased, the number of fusarium oxysporum in the soil is reduced (the number of the fusarium oxysporum in the soil is smaller than or equal to 8.4*10<3> cfu per gram of soil, and when the number of the fusarium oxysporum in the soil is below 10*<4>cfu per gram of soil, the cucumber fusarium wilt can be effectively prevented and controlled), and a disease suppression type soil microflora is established. Test results show that after the soil which is subjected to continuous cropping for nine years, has higher cucumber fusarium wilt morbidity and nearly has no harvest is processed by the method, through comparison and contrasting, the morbidity is reduced by 88.5 percent, and the cucumber fruit yield is increased by 350 percent. The method provided by the invention has the advantages that the cucumber fusarium wilt can be effectively inhabited, and the sustainable development of intensive cucumber production is ensured.

Description

1. Technical field

[0001] The invention relates to a method for combined use of non-toxic and non-residual soil treatment and bio-organic fertilizer for preventing and controlling cucumber wilt, and belongs to the technical field of agricultural intensive production. 2. Background technology

[0002] Cucumber wilt is the main limiting factor in the continuous cropping of cucumbers in greenhouses and outdoors, and it causes serious losses to cucumber production every year, especially after three seasons of continuous cropping, sometimes the incidence of Fusarium wilt reaches more than 80%, or even the output is lost.

[0003] The control methods of cucumber wilt mainly include breeding of resistant varieties, chemical control and biological control. Among them, the selection of disease-resistant varieties has a long cycle, and the resistance of the original cucumber varieties is difficult to play a role after the mutation of the physiological race of the pathogenic bacteria o...

Examples

Embodiment Construction

[0023] (1) Liquid ammonia fumigation

[0024] Plow the soil where cucumber wilt occurs frequently or severely to a depth of 25 cm. When the soil moisture content is below 30%, cover it with a plastic film and tighten its surroundings. Pass one end of a pressure-resistant plastic pipe equal to the length of the ridge into the plastic film ( figure 1 ), leave a small hole every 1.5-2.5 meters on the plastic pipe, let the liquid ammonia gasify and release it at multiple points in the shed to ensure that its concentration is evenly distributed. The other end of the pressure-resistant plastic pipe is connected to the pressure reducing valve of the special tank body of the liquid ammonia cylinder ( figure 1 ), generally choose to open the hydraulic valve near noon, release liquid ammonia once a day, each time for 2 minutes or when the ammonia concentration in the shed reaches 3500ml / m 3 Stop the air supply when the air supply is stopped, and put it 3-6 times in total for 300 squar...
