The rhizome of Yellow Lotus is yellow, branched and has many fibrous roots. The leaves have very long petioles that are about 5-12cm in length, and the leaf blades are ovate-triangular. It has 1-2 scapes, about 12-25cm in height, and the petals are linear or linear-lanceolate. The seeds are long elliptic, usually with 7-8 seeds.
The yellow dock is more demanding on light when planting, so try to choose half sunny slopes for planting, the yellow dock doesn't need much sunlight in the early planting stage, but with the growth of the yellow dock, the demand for light will increase, so it's best to choose half-sunny slopes when planting. Or in the pre-planting stage of the planting of Huanglian shade planting.
When planting Huanglian, it is best to choose a soil that is loose and fertile. After the soil is selected, the soil should be deep tilled fertilization. In the fertilization of the best use of organic fertilizer as the field of the base fertilizer, after the fertilization, the soil for leveling. After the fertilization, the soil will be leveled. After that, the land will be made into beds. The width of the border is about 1.5 meters. After the ditching to level the beds can be planted.
The growth cycle is long when planting, which also makes the growth rate of the yellow dock vary after planting. This is very troublesome to manage. So before planting try to give Huanglian continue to screw a seedling for planting. Huanglian planting time is generally divided into three sections, the first planting is generally planted in late September, the second planting is generally planted in early December. The last planting is done in February. When we are planting, we first evenly spread the seeds on top of the seedbed. Afterwards, water and mulch. After mulching, it's best to cover it with straw or film once. This way, the yellow germination speed will be faster.
When the seedlings grow to about 10 centimeters, they can be transplanted. Huanglian's seedling emergence time is usually in February and March. We try to transplant in May when the weather is warm. The weather is warmer at this time, and the survival rate of Huanglian seedlings will be increased accordingly. When transplanting Huanglian, we should not plant too densely, and generally plant according to the spacing of 15 centimeters between each row and 10 centimeters between each plant. If too dense, it will make Huanglian in the growth of each other, which is very unfavorable to the growth of Huanglian.
The yellow dock in the planting of high yield, water and fertilizer is indispensable. After transplanting the yellow dock, we have to water it once, which can better help the yellow dock to adapt to the new environment, so that the survival rate of the yellow dock can be improved. The first fertilizer should be applied 3 to 5 days after planting. When fertilizing, try to use manure to fertilize.
The second application of fertilizer should be done when the yellow dock blooms. In this fertilization, try to use Trim Phosphorus and Potassium fertilizer for fertilization. The last fertilization should be done when the stem of the yellow dock starts to expand;. The use of Cuim Potassium fertilizer can be very good to help the expansion of yellow dock stems. In the field management time also can not forget to give yellow yellow watering and weeding.
The yellow dock needs to grow in a cooler environment in the early stages of growth, and if it receives sunlight at this time, it will cause burns. So Huanglian pre-shade work should be done, in the Huanglian blossom can be successively let it see a little sunshine. When the rhizome starts to expand, it needs a lot of sunlight. This time there is no need to shade.
