The experiment was carried out in the greenhouse of the Agricultural Demonstration Park in Lancang Town, Santai Town, Dongtai City. The nursery adopts the light-substrate tray method, and the temperature and humidity are detected by a warm-humid light carbon dioxide recorder, and then controlled by computer intelligence. The errors do not exceed ±0.5°C and ±RHS%, respectively. There are a total of 13 treatments in this test, of which 12 treatments are different temperature and humidity settings (different humidity in three sections of low temperature, medium temperature, and temperature adjustment), and one is a conventional nursery control (CIA). The temperature regulation adopts the boiler hot water pipe circulation heating, the humidity adjustment adopts the fan ventilation and spray, the treatment spacing is 3.5m, is completely separated by the two-layer film, all the tests are carried out in the greenhouse, all the processing temperatures are Above 18°C, it can meet the normal temperature requirement for nursery.
The parameters in the test space were measured using a thermo-optical light carbon dioxide recorder. The range of temperature adjustment was 1,803,35.50C (low temperature, 18.50C, 230C, medium temperature, 24.50C, 290C, and high temperature, 30.50C, and 350C). The humidity adjustment range was Relative humidity 60%} 90%. The temperature adjustment gradients are respectively 18.50C, 200C, 21.50C, 230C, 24.50C, 260C, 27.50C, 290C, 30.50C, 320C, 33.50C, 350C, and the gradient of the humidity adjustment is 60%RH, 70%RH, respectively. 80% RH, 90% RH, 12 treatment temperature, humidity combination set to (18.50C, 60% RH), (200C, 70% RH), (21.50C, 80% RH), (230C, 90% RH ), (24.50C, 60%RH), (260C, 70%RH), (27.50C, 80%RH), (290C, 90%RH), (30.50C, 60%RH), (320C, 70% RH), (33.50C, 80% RH), (350C, 90% RH), represented by treatment codes T1, T2, T3, T4, TS, T6, T7, T8, T9, T10, T11, T12, respectively; The code name is CIA, which is carried out according to the conventional method of factory cultivation. The test site is a solar greenhouse in the north and south direction. The plot is 10mZ for each treatment inspection and is selected at the same position in the middle of a standard breeding bed (50mx2m). The plug specification is: 25cm x 50 (two, 200 points/pan, 80 trays per treatment) , 16,000 hole seedlings; sowing: Taiwan Keyang PN-20-2 needle seeder; the treatment room are sealed with a film, the interval between processing is 3.5m.
According to the data recorded by the temperature-humidity carbon dioxide recorder, statistical analysis was performed according to the inspection data of pepper seed disintegration among various treatments. T4 treatment was the most severe, reaching 15.38%, and T9 treatment was the lightest, 0.69%, CI incidence. It was 6.71% and the average incidence rate was 4.37%. Different temperatures and humidity have effects on the incidence of shattering disease. Low temperature and high humidity can easily induce shattering disease. High temperature and low humidity can curb the incidence. According to statistical analysis of data on virus diseases among treatments, T10 treatment was the most severe, reaching 6.95%, T3 treatment was the least, with 0.46%, CI incidence was 3.82%, and the average incidence was 2.27%. Different temperatures and humidity have an impact on the incidence of viral diseases. High temperature and low humidity are suitable for virus development. Low temperature and high humidity have inhibitory effects on viral pathogens.
