地膜覆盖栽培,能促进花生增产增收是无疑的。但地膜覆盖中常发生烂果现象,我县金厂大队1979年开始搞地膜栽培以来,无论在小区试验或大面积生产上,均有烂果现象发生,一般烂果率(单墩烂果占结果数的百分率,下同)在10—20％,多者达60—70％. 据我们分析,烂果的原因在于高温多湿,而多湿起主导作用。地膜覆盖后,土壤水份由下向上密集于结实层或地表层,前期具有促进花生秸棵和荚果早生快发的作用。但在土质粘重的地块,特别在高温多雨季节,由于排水不畅,透气不良,便会使膜内土壤长时间处于高湿缺氧状态,早期结成的荚果只能烂掉。 Film mulching cultivation, can promote peanut increase yield is undoubted. However, the phenomenon of rotten fruit often occurs in the mulching. Since the Jinchang Plant of our county began to cultivate the mulch in 1979, both rotten fruit and rotten fruit occur in the plot test or large area production. The same below) in 10-20%, more than 60-70% .According to our analysis, rotten fruit is due to high temperature and humidity, and wet play a leading role. After mulching, the soil moisture from bottom to top intensive in the stratum or surface layer, early to promote early peanut straw and pod role in hair growth. However, on parcels of soil quality, especially in the hot and rainy seasons, the soil in the film is exposed to high humidity and oxygen for an extended period of time because of poor drainage and poor ventilation. The pods formed in the early stage can only rot.
