辣椒日烧病是高温季节辣椒的常发病害。据笔者调查,一般病果率10～30%。重病田块在50%以上,严重地影响了辣椒(尤其是甜椒)的产量和品质。发病原因除日光直射外,我们还发现了几个栽培因素对发病的影响,现报道如下:一、盖膜对日烧病发生的影响。盖膜栽培可以提早定植,促壮苗早发。如果能在高温到来前椒棵封垄或及时撤掉地膜则可减轻日烧病,反之,则加重其害。据我们多点调查结果,未封垄而仍盖膜者,日烧果率3.3～32.5%,平均19.8%,而未盖膜或已撤掉膜者病 Hot pepper hot disease is the perennial hot pepper disease. According to the author’s survey, the general disease rate of 10 to 30%. Severe disease block more than 50%, seriously affecting the pepper (especially sweet pepper) yield and quality. The cause of the disease In addition to direct sunlight, we also found several cultivated factors on the incidence, are reported as follows: First, the cover film on the impact of Japan’s disease. Cover film cultivation can be early colonization, and promote strong seedlings early hair. If the hot pepper can be sealed before the ridge or timely removal of mulch can reduce the Japanese burn disease, on the contrary, it aggravate the damage. According to our multi-point survey results, there is no closure of the ridge and still cover the membrane, the fruit burning rate of 3.3 ~ 32.5%, an average of 19.8%, without membrane or removed membrane disease
