Abstract
The invention discloses a composition for radix ophiopogonis planting. The composition is prepared from the following components in parts by weight: 799 to 1,051 parts of a nitrogen fertilizer, 1,904to 2,296 parts of a phosphate fertilizer, 823 to 901 parts of a potash fertilizer and 44 to 59 parts of paclobutrazol. The invention further provides the application of the composition in a Sichuan radix ophiopogonis planting process and an application method of the composition. According to the composition provided by the invention, on the basis of reducing the use amount of the paclobutrazol, the over-ground part of Sichuan radix ophiopogonis can fully grow; the leaf dry weight and the number of leaves are correspondingly increased, so that the yield and the quality of the Sichuan radix ophiopogonis are improved. Compared with the prior art, the composition disclosed by the invention has the advantages that the fresh yield is increased by 66.40 percent, the dry yield is increased by 66.46 percent, the content of water-soluble extracts is increased by 1.21 percent, and the content of total saponins is increased by 31.43 percent.
Description
technical field [0001] The invention relates to the field of traditional Chinese medicine planting, in particular to a composition for planting Ophiopogon japonicus. Background technique [0002] In recent years, in the production area of Ophiopogon japonicus in Sichuan, a compound fertilizer with a ratio of nitrogen, phosphorus, and potassium of 1:1:1 has been mainly used in the process of planting Ophiopogon japonicus. The ratio of this compound fertilizer is unreasonable. Since the existing technology shows that the use of paclobutrazol can increase the yield of Ophiopogon japonicus, a large number of growers in the Chuan Ophiopogon production area of Sichuan have increased the amount of paclobutrazol to correct the problem of unreasonable compound fertilizer ratios, making the amount of paclobutrazol used from the initial 15kg / hm 2 Evolved to the current 150kg / hm per mu 2 . However, paclobutrazol has strong adsorption in the soil, and most of it remains in the soil...
