Problems solved by technology
At present, the survey of the number of sclerotia in the field mainly uses the visual inspection method, and only the number of sclerotia in the surface soil is investigated, and the number of sclerotia 10cm below the soil cannot be counted. It is difficult to accurately investigate the germination and infection incidence of different types of rapeseed varieties in different regions, which affects disease prediction, early warning and effective control

Embodiment Construction
[0013] Referring to the accompanying drawings, the present invention comprises a rectangular enclosure surrounded by 4 rigid fences 1, 2, 3, 4, a top plate 6, an inserting plate 5 at the bottom of the closed rectangular enclosure, the inserting plate 5, the enclosure 1, 2 , 3,4 are provided with aperture less than the sieve hole 100 of rape sclerotia; Wherein a pair of parallel fences 1,3 of described rectangular enclosure are provided with inserting plate guide groove 7, described inserting plate guide groove 7 is along the pair of fences. A linear groove in the corner line direction, the flashboard 5 is slidably connected in the flashboard guide groove 7; wherein a pair of parallel fences 1 and 3 tops of the fence are set at 10 cm from the bottom end of the fence. There is a slot 8 of the top plate, and the top plate 6 is inserted into the slot 8 .
[0014] The fence can adopt a scheme in which there are metal frames on the left, right, upper and lower sides, and the fence s...

The invention provides a sclerotinia scleotiorum cultivation device which comprises a rectangular enclosing frame which is formed by the enclosing of detachably connecting fences, an inserting plate for sealing the bottom of the rectangular enclosing frame, and a top plate, wherein the top plate and the fences are provided sieving holes; the rectangular enclosing frame is provided with inserting plate guide slots which are inclined linear slots, and the inserting plate is connected in the inserting plate guide slots in a sealing way; the enclosing frame is provided with top plate inserting slots, and the top plate is inserted in the top plate inserting slots; in the cultivation device, connecting posts are arranged at the four corners of the rectangular enclosing frame, two ends of the fences are inserted into the connecting posts, the bottoms of the fences and the bottom of the connecting posts are respectively provided with grounding nails, and the connecting posts are provided withinserting depth limit structures. The device has the advantages that the field surface oil sclerotium survey sampling is scientific, the sclerotium quantity statistics at a sampling point is accurate, the sclerotium germination and infectious pathogeny observation is timely, the data comparison is accurate, and the occurrence of sclerotinia scleotiorum with different types at different regions can be accurately surveyed and observed. The device can be widely applied in the survey and the infectious pathogeny observation of the numbers of sclerotinia scleotiorum, rice, vegetable and other fungal disease sclerotinia.
Description
technical field [0001] The invention relates to a field rape sclerotinia sclerotia incubator for a class of fungal diseases such as rape sclerotinia. Background technique [0002] Rapeseed is the main oil crop in my country. Sclerotinia sclerotiorum is the most serious fungal disease on rapeseed. It has a high frequency of prevalence all year round. Generally, it can cause 20%-50% reduction in rapeseed yield and 5%-10% reduction in oil content. Do a good job in rapeseed The monitoring and control of sclerotinia is of great significance to ensure the bumper harvest of rapeseed. To prevent and control rapeseed sclerotinia, the first thing to do is to monitor and forecast the disease. The occurrence of rapeseed sclerotinia mainly occurs through the germination of sclerotinia (top soil 10cm) left in the field and infects rapeseed plants, causing disease in rapeseed plants. Therefore, do The investigation of the number of Sclerotia sclerotiorum in the field and the observation of...
