在白浆土上开展玉米降解地膜种植与祼地种植的效果比较试验,并对其生育期、生物学性状及产量等进行调查分析。结果表明,降解地膜种植玉米,可明显提高保苗率、提高穗粒数、提高千粒重,使玉米出苗期、吐丝期及成熟期提前5~6 d。降解地膜种植玉米较裸地种植增值1 899.96元/hm2,同时节省清除地膜所需费用。因此,桦甸市地白浆土应用降解地膜种植玉米,是高产稳产达到高效生产的根本保障。
In white soil to carry out maize degradation of plastic film planting and land cultivation comparison test, and its growth period, biological characteristics and yield were investigated and analyzed. The results showed that planting corn with degraded plastic film could improve the seedling protection rate, increase the number of grains per spike, increase the 1000-grain weight, and improve the emergence, silking and maturity of maize by 5 ~ 6 d. Degradation of plastic film planting corn than bare planting value of 1 899.96 yuan / hm2, while saving the cost of removing the film. Therefore, the application of biodegradable corn in Huadian City is the fundamental guarantee of high and stable yield and efficient production.
