抚宁县是我省的油料出口基地县之一,全县种植花生9.6万亩,其中地膜花生6.5万亩,平均亩产230公斤,比裸地花生增产一倍以上。抓播种、保全苗是夺取地膜花生高产的关键,应抓好以下技术措施。 第一、底墒足。土壤墒情以田间持水量的60—70%或绝对含水量的16—18%为合适,即手握成团落地松散为适宜。墒情差,种子难发芽,湿度大,种子易霉烂。春季多大风少雨天气,土壤容易失墒,必须强调缺墒补墒。最好用喷雾机喷水,也可不隔沟浇水,要防止大水漫灌,延误播期。 第二,底肥饱。因为地膜花生在生育期间只能 Funing County is one of the province’s oil export base counties, the county planted 96000 acres of peanuts, of which 65000 acres of plastic film peanuts, the average yield 230 kilograms, more than double the peanut yield. Grasp sowing, seedling protection is to seize the key to high-yield plastic film peanuts, should pay close attention to the following technical measures. First, the end of foot enough. Soil moisture to the field of water content of 60-70% or 16-18% of the absolute water content is appropriate, that is, holding hands loose into groups suitable. Poor moisture, difficult to germinate seeds, humidity, easy to rotten seeds. How windy and rainy weather in spring, the soil vulnerable to loss of moisture, we must emphasize the lack of moisture upkeep. Spraying water is best to use, but also do not ditch watering, to prevent flood irrigation, delayed sowing. Second, the end of fullness. Because plastic film peanuts only during birth

马铃薯(Solanum tuberosum L.)是四大粮食作物之一,具有丰富的野生资源。马铃薯青枯病是由茄科的雷尔氏菌(Ralstonia sozanacearum)引起的毁灭性的细菌性病害,在马铃薯生产中造成重大损失,目前还没有有效的防治措施,选育抗病品种是最有效的途径。但是在马铃薯栽培种中尚未发现青枯病抗源,仅在野生种、原始栽培种中存在少数青枯病抗性材料,因而扩大马铃薯遗传基础是加快马铃薯青
