First of all, environmental choice
The quality of soil determines the development of Ophiopogon japonicus seedlings. If the soil is particularly good and the living environment is particularly good, the gardener's maintenance will be much simpler. Ophiopogon japonicus has low requirements on soil quality, which can be sand, yellow mud and clay, but the soil with large sand content germinates generally. Ophiopogon japonicus is afraid of flooding and needs high terrain to facilitate drainage. When rainy days come, there is too much rainfall, so the accumulated water should be drained in time, otherwise it is easy to die locally. The terrain focuses on draining water, with similar soil quality and abundant sunshine.
Second, soil preparation
1. Cultivated land: Ophiopogon japonicus is very sensitive to fertility. If the soil fertility is sufficient, the flowers will look good and the plants will be strong. However, the soil fertility of many scenic spots is similar. If you want to blossom well, you must sprinkle enough base fertilizer before planting, and sprinkle 3.5~8 tons of cow dung and pig manure per mu. Plow the fertilizer once and rake it carefully, so that the soil and fertilizer are evenly mixed together, and there is no big clod, which is convenient for planting and improves the germination rate.
2. Border-making: In order to facilitate the maintenance of Ophiopogon japonicus seedlings such as watering, weeding and fertilization in one year, Changjing Garden suggests that you make the land into a fixed standard border with a width of 1.4m and a length of 16 ~ 25m depending on the terrain.
Third, the planting method
Ophiopogon japonicus seeds have average particle size and good germination rate. Shallow planting is recommended, and the depth of soil cover should not exceed 5 cm. Basically, the seeds of Ophiopogon japonicus are mixed with wet sand under the condition of low wind and evenly scattered on the ground. After planting, soil can be covered by hand or machinery, and the germination rate can be improved about 6~ 10 days after soil covering.
Fourth, the maintenance method
The workload of management and maintenance of Ophiopogon japonicus in the growth period is very small, basically disease-free, and the development trend is very strong. Most important things are concentrated in the flowering period. Before the flowers bloom, apply 50 kilograms of compound fertilizer per mu. The purpose of topdressing before flowering is to prolong the flowering time, increase the amount of flowers and make the color more gorgeous. There is no need for fertilization when flowering, and Ophiopogon japonicus needs enough water when flowering. At this time, it is necessary to water it according to meteorological conditions.
