Cultivation techniques of goldfish grass (leading flower)

Goldfish grass, also known as dragon head flower, lion flower, ocean sparrow and so on, originated in the Mediterranean region, because the flower shape is similar to goldfish, has a high ornamental value, at the same time, it is also a blindly traditional Chinese medicine. So, what are the cultivation techniques of goldfish grass? Let's get to know it together.

I. sowing environment

Goldfish grass has strong cold resistance and is not suitable to grow in an environment of high temperature. it is best to plant it in a sunny or half-sunny place, choose a soil with normal drainage, deep soft soil layer and strong permeability, pay attention to soil fertility, not too barren, and do a good job of soil preparation and deep disinfection to prevent residual bacteria from harming the growth of goldfish grass, and then apply sufficient fertilizer. The base fertilizer is mainly fully mature farm manure to meet the sufficient nutrition needed for the growth of goldfish grass.

Second, sowing seeds at the right time

Goldfish grass is mainly planted by sowing, and the spring and autumn season is the best sowing time for goldfish grass, but this time should be changed according to the planting area. The Yangtze River valley is generally sowed in autumn, and the seedling growth ability in autumn is stronger than that in spring. The flowering rate is high. In order to promote germination before sowing, the seeds should be replanted in gibberellin and other solutions for seed sowing, and attention should be paid to sowing density when sowing. After sowing, cover fine soil and compaction, ensure that the seeds are in full contact with the soil, and then pour enough water to ensure that the soil is moist, control the temperature, prevent water from evaporating too quickly, and improve the germination rate of seeds.

III. Seedling management

Under normal management after sowing, it can sprout about a week later, and then the plastic film should be opened in time to promote the top soil of the seedlings and receive light. During the growth of the seedlings, about two times of interseedling work should be carried out to ensure that each seedling can grow healthily. When the seedlings grow out about 5 true leaves, they can be transplanted and planted. When transplanting, we should pay attention to transplanting with soil as far as possible to prevent the lack of water and affect the development of the seedlings. Before transplanting, we should do a series of work on the field, control the planting density, dig the planting ditch, irrigate enough water after planting, do a good job of topdressing, strengthen field management, and improve the survival rate of planting.

IV. Field management

Goldfish grass contains rhizobium and has a strong effect of nitrogen fixation, so there is no need to topdressing nitrogen fertilizer, but mainly phosphorus and potassium fertilizer. Proper topdressing of phosphorus and potassium fertilizer can improve flower quality and enhance petal glossiness. It is very important for the growth of goldfish grass. In the planting process, it is necessary to do a good job of coring, usually once when the seedlings grow to about 14 centimeters, and then coring again at 20 centimeters. Coring can effectively promote the growth of lateral branches, improve the flowering rate and increase the ornamental value of the commodity.

The above are the cultivation techniques of goldfish grass, I hope I can help you!
