摘要
为了探寻不同灌水定额对粤西主要北运蔬菜品种——辣椒生长效果的影响,试验区选在粤西的化州市鉴江区柴脚岭建设农场内,进行大田试验。根据当地的灌溉习惯以及辣椒的需水情况,固定灌水次数和每次灌水时期,采用不同的灌水定额进行对比试验,即设定灌水控制上限分别为田间持水量(θ_田)的90%、80%、70%和60%,试验表明,灌水上限为80%θ_田时辣椒产量最高,其次为90%θ_田、70%θ_田和60%θ_田。试验成果可为当地辣椒推广节水灌溉提供科学依据。
In order to research the different irrigation quota on vegetable varieties pepper growth effect in the west of Guangdong Province,Chaijiaoling Farm of Jianjiang area at Huazhou City in the western Guangdong is selected as the test area,and field experiment is carried out at this area. According to the local irrigation habits and pepper water demand,irrigation times and irrigation period are fixed to different irrigation quota contrast test,that is,upper irrigation control limits are set respectively for the field to water（ 90% θ_田,80% θ_田,70% θ_田and 60% θ_田）. The experiment shows that irrigation upper limit for 80% θ_田is the highest,followed by 90% θ_田,70% θ_田and 60% θ_田. The experimental results can provide scientific basis for the promotion of water saving irrigation for local pepper.
