大力子系一种常用中药,近年来各地普遍栽种,惟产量不高,每亩约产200—300斤。湖南邵东九龙岭公社,对栽培大力子有丰富的经验,去年该社创亩产大力子800斤的高产记录。其丰产培育方法是:一、选择良种:在大力子收获时,选择无病虫害颗粒饱满的成熟种子,阴干作种。由于严格选种,可保证发芽率。二、选地整地:选择地势较高、土质肥沃而稍潮润的粘性黄泥土栽种为最好。春初将选好的土地深耕一尺以上,打碎整平,然后按行距4尺,株距5尺打穴,穴深二、三寸,每亩用灰肥500斤大粪200斤(发酵后)作基肥。三、播种:在春初二、三月播种,每穴下种4—5粒;播种前每穴施放火土灰一把,每亩约需火土灰肥2,000斤。播后约十天左右即可发芽。
The Daweizi is a commonly used traditional Chinese medicine, which has been widely planted throughout the country in recent years. However, the yield is not high, and the yield per mu is about 200-300 pounds. Hunan Jiulongling Community, Shaodong, Hunan, has rich experience in cultivation of Daweizi. Last year, the agency created a high-yield record of 800 pounds per mu. Its high yield cultivation method is: First, choose the good seed: When the Datongzi harvest, select the mature seeds without pests and pests, and dry for the seed. Due to strict seed selection, germination rate can be guaranteed. Second, the choice of site preparation: choose a higher ground, soil fertile and slightly moist run sticky yellow mud planting is the best. In the beginning of the spring, the selected land will be ploughed more than one foot, broken and leveled, and then the spacing will be 4 feet, the spacing between the plants will be 5 feet, the depth of the hole will be two or three inches, and the ash fertilizer will be 500 pounds and 200 pounds per mu (after fermentation). As base fertilizer. Third, sowing: In the spring of February and March sowing, planting 4-5 seeds per hole; before sowing a fire ash per hole, about 2,000 pounds per acre of fire and soil ash. About ten days after sowing can germinate.
