一试验的目的人参系一种多年生珍貴的药材,每年生长时期短,生长发育比较缓慢,参根与种籽产量亦低;一般种参习惯都不进行施肥,因此作者参照其他作物的根外追肥方法来研究根外追肥对人参所起的作用。本试验的目的,就是在人参生长季节,进行根外喷肥来提高种籽与参根产量。二试验材料和方法本试验选用四年生二等参苗,于吉林省撫松参埸的新林地上进行试验,其方案为: 1.过磷酸钙1% 2.过磷酸钙2% 3.氯化钾1% 4.高锰酸钾0.2% 5.对照采用对比法排列,磷肥三次重复,钾肥二次重复,统计区四平方米,保护区一平方米,行距20公分,株距14公分,每统计区共有参苗160株。
The purpose of a test of ginseng is a perennial rare medicinal herbs, annual growth period is short, relatively slow growth and development, root and seed yield is also low; the general practice of ginseng will not be fertilized, so the authors refer to other crops top dressing Method to study the effect of root top dressing on ginseng. The purpose of this experiment is to increase the yield of seeds and root of ginseng by spraying fertilizer outside the root during the growing season of ginseng. The second test materials and methods In this experiment, four-year-old second-seeded seedlings were selected to test the new forest land in Fusong, Jilin Province, the program is as follows: 1 superphosphate 1% 2 superphosphate 2% 3 chlorination Potassium 1% 4. Potassium permanganate 0.2% 5. Control by contrast method arrangement, phosphate fertilizer three times repeated, potassium fertilizer repeated twice, the statistical area of four square meters, protected area of one square meter, row spacing of 20 cm, spacing of 14 cm, each statistics District Senate total of 160 plants.
