人们把花生从开花到初见饱果这段时间称作中期生育阶段。这段时间花生所需的营养最多,生长速度最快,如果营养缺乏,势必导致减产。因此,科学地抓好中期管理,及时追好花期肥料是保证花生增产的关键。追肥的种类和数量,要根据地力水平、花生长相来确定。一般来说,肥力高、长势好的地块,主要追施磷、钾肥,亩追过磷酸钙20—30公斤,草木灰50—100公斤,少追或不追氮肥。地力薄、长势差的地块,氮肥为主,每亩可追施标准氮肥10—20公斤,过磷
People call peanuts from flowering to full bloom for the first time. During this time, peanuts need the most nutrition and the fastest growth rate. If nutrition is lacking, it will inevitably lead to the reduction of production. Therefore, scientifically grasp the mid-term management, timely chasing the flowering fertilizer is to ensure that the key to peanut production. The type and quantity of topdressing should be determined according to the level of soil fertility. In general, fertile, growing good plots, the main topdressing phosphorus, potash, chasing 20-30 kilograms of calcium phosphate, ash 50-100 kg, chase less or not chasing nitrogen. Thin, poor growing plots, mainly nitrogen, nitrogen fertilizer can be topdressing 10-20 kg per mu, over phosphorus
