浙江省磐安县深宅乡上享堂高級农業社第二小队,在1957年于当地水鎮头山的四等土地上种植元胡0.79市亩(該乡土地以土層深淺分作7等,4等地的土層厚为1.2—1.5尺),收获水子元胡788斤,平均每亩达水子997.6斤。每斤下种籽可生長水子14.25斤,如以300斤水子折合干子100斤,則每亩产干元胡332.531斤。获得高額产量的主要經驗是: (一)选留良种,妥善儲存:种籽的好坏是直接关系到今后生产量的高低,因此必須在每年立夏后10天,一面收获,一面即进行粒选。选种标准以不大不小均匀的呈扁圆球形無病虫害和無伤疤为佳。同时必須剔除老元胡(俗称元胡娘,即上年下种的元胡籽)。挑选后平攤在太陽照不到的陰涼干燥处,約过三、四天待其表皮稍干时方可以放入竹簍里收藏。收藏方法:(1)
Zhejiang province Pan’an County Shen Zhaitang Advanced Rural Cooperatives second team, in 1957 on the fourth-class land in the township of water head Yuhu 0.79 city acres of planting (the township of soil depth sub-divided into 7, etc. , 4 and other places of soil thickness of 1.2-1.5 feet), Harvest Yuanzi 788 pounds, an average of 997.6 pounds per acre of water molecules. Seeds per kilogram can grow 14.25 pounds of seed water, such as 300 pounds of water equivalent to 100 kg of dried seeds, the per-mu yield stem 332.531 pounds. The main experience of obtaining high yield is: (1) The selection of good seeds for proper storage: The quality of the seeds is directly related to the level of production in the future. Therefore, it must be done 10 days after the end of summer every year, . Selection criteria to be uniform and uniform was oblate spherules and no scars better. At the same time must remove the old Yuan Hu (commonly known as Yuan Hu Niang, that is, the seed of the previous year Huohu seed). After the selection of equal parts in the sun can not reach the shady and dry place, about three or four days until the epidermis slightly dry before it can be placed in the bamboo basket collection.
