摘要
于2019年在湖北省红安县进行花生(Arachis hypogaea)覆盖地膜与露地(CK)栽培的对比试验,分析地膜花生与露地花生田间5~10 cm地温、土壤含水率、土壤容重、土壤孔隙度和花生发育期、产量因素及产量差异。结果表明,地膜花生比露地花生不仅具有较明显的保温增温效果,同时还具有保水保湿、降低土壤容重、提高土壤孔隙度,从而防止土壤板结等综合效应,促使花生早出苗、早开花、早下针、早结荚、早成熟,产量显著提高,经济效益明显。
The comparative text of peanut(Arachis hypogaea)under two cultivation pattern of plastic film and open field(CK)in Hong’an county of Hubei province in 2019 was carried out. The differences of ground temperature,soil moisture content,soil bulk density,soil porosity,peanut development period,yield factors and yield between plastic film peanut and open field peanut were analyzed. The results showed that the plastic film peanut not only had a better effect on heat preservation and temperature increase than the open field peanut,but also had a comprehensive effect on water and moisture retention,reducing soil bulk density and increasing soil porosity,so as to prevent soil from sloughing,promote peanut early emergence,early flowering,early needle,early pod,early maturity,significantly increased yield and economic benefits.
