Problems solved by technology

[0004] At present, there are many researches on the health care, classification and geographical distribution of sagegrass, but the purpose of sagegrass as turfgrass is not to harvest tubers, but to obtain a good lawn effect. There are very few studies on the effect of turfgrass on the effect of turf and the condition of fertilizers suitable for the growth of turf

Embodiment 1

[0011] The dwarf step grass clone introduced from Japan was used as the research object.

[0012] The fertilizer is prepared by mixing the following raw materials: 1 / 2 Hoagland nutrient solution is added with pure urea, potassium dihydrogen phosphate and potassium sulfate to make N, P 2 o 5 and K 2 O concentrations are: 32mg / L, 20mg / L, 12mg / L.

[0013] For one-year-old dwarf stepgrass plants with 8-10 leaves, first use 1 / 2 Hoagland nutrient solution to cultivate for 20 days, then apply this fertilizer, and then supplement it every 7 days. Groups were administered 1 / 2 Hoagland nutrient solution.

[0014] Use the fertilizer of the present invention to the following impact on the growth of the upper part of the dwarf step grass: the rate of turfgrass blade expansion is to represent the time required for the blade to fully expand, and the smaller the value, the faster the blade grows and the faster the speed of covering the ground. The level of chlorophyll content is an import...

Embodiment 2

[0018] The fertilizer is prepared by mixing the following raw materials: 1 / 2 Hoagland nutrient solution is added with pure urea, potassium dihydrogen phosphate and potassium sulfate to make N, P 2 o 5 and K 2 O concentrations are: 32mg / L, 20mg / L, 24mg / L.

[0019] The growth rate of leaf elongation in the experimental group was 0.51 cm / week, which was significantly higher than that in the control group. The leaf unfolding rate was 5.17d / leaf, which was significantly lower than that of the control group. The chlorophyll content of leaves was 2.004mg / g·FW, significantly higher than that of the control. The number of new roots and root activity in the experimental group were significantly higher than those in the control group.

Abstract

The present invention provides a fertilizer of Ophiopogon Japonicus and is characterized in that the ratio of the weight percentage of N, P2O5 and K2O is equal to 7 to 3 to from 8 to 8.5. The N, P2O5 and K2O are respectively provided by pure urea, potassium dihydrogen phosphate and potassium sulfate. The fertilizer of Ophiopogon Japonicus is prepared according to the growth characteristics of the Ophiopogon Japonicus, the required nutrients, the rules about the fertilizer, as well as the types and the content characteristics of nutrients that are provided by soil; thus the fertilizer has the targeted, efficient, scientific, dynamic and other characteristics. The application of the fertilizer can obviously improve the chlorophyll content in the leaves of the Ophiopogon Japonicus, and can adjust the biomass distribution on the ground and under the ground, so as to promote the growth of plants.

Description

technical field [0001] The invention belongs to fertilizers, and in particular relates to a fertilizer for dwarf phalaenopsis. Background technique [0002] In recent years, with the improvement of people's living standards, the requirements for the living environment are getting higher and higher, and the lawn industry in our country has developed rapidly. Different lawn functions require different types of turfgrass to be selected. The requirements for turfgrass are different from gardens and flower beds in scenic forests, because there are often tourists in scenic forests, and the maximum vegetation coverage is required to make visitors feel pleasing to the eye. The canopy density under the forest is very high, and the turfgrass must have the following four characteristics: the first is shade tolerance, which can be suitable for the canopy environment under the dense forest; the second is evergreen, which ensures the landscape in all seasons; the third is ornamental Sexu...
