What do you need to pay attention to when planting Asarum?

Asarum, also known as Asarum, is a kind of perennial herb of dicotyledonous class and Asarum genus. It has the effects of dispelling wind, dispelling cold and opening orifices. it is often used in medicine to treat headache, nasal abyss, toothache and rheumatic paralysis and other diseases. Asarum cultivation in China is mainly distributed in the early northeast, in which Jilin and Liaoning are the main producing areas. So what the editor wants to share with you today is the main issues of Asarum planting. Let's take a look.

1. Soil selection

Wild Asarum generally grows under the forest, because the general soil under the forest is rich in humus, which is suitable for the growth of Asarum, so we can also choose to plant under the forest. If we choose to plant in the field, we should choose sandy loam with deep soil layer, rich humus, loose soil, adequate fertilizer and convenient drainage and irrigation. In particular, clayey soil and poor soil areas can not be planted, otherwise it will occur frequently, which increases the difficulty of planting, at the same time, the yield is not high and the quality is not good.

2. Planting time

The planting time of Asarum is related to its planting mode. If fresh seeds are used, we usually start sowing in early July, no later than early August, because the longer the seed is stored, the lower its germination rate. If the newly collected seeds are sown, the germination rate is as high as 96%, but if the seed is placed for more than 60 days, then the germination rate of the seeds is only 2%, so sow as soon as possible. The use of ramet propagation and rhizome propagation, generally as long as planting in the summer, there is no excessive requirements.

3. Density management

Planting density has a great impact on the yield and quality of Asarum. At the same time, in the later stage of field operation, reasonable planting density is also convenient for growers to carry out field management, which can also reduce the difficulty of labor. No matter which planting method is adopted, the spacing between rows is generally fifteen centimeters and the spacing between plants is about ten centimeters. Of course, we also need to reasonably regulate the planting density of Asarum according to the degree of fertility of the planting land, and improve the utilization rate of land resources as much as possible.

4. Water and fertilizer management

Water and fertilizer management is the key to high yield and high quality of Asarum. During the growth period of Asarum, in addition to base fertilizer, topdressing should be carried out twice a year. Topdressing is applied in May and September every year, mainly with ammonium sulfate in the interrow ditch. Of course, we can also use a mixture of pig manure and superphosphate to fertilize, which is said to be extremely effective. In addition, in the process of planting, we can cover the ground with a layer of rotten fallen leaves, which can not only provide nutrients, but also protect fertilizer and water. Finally, it is necessary to water reasonably in the dry season every year to maintain the moisture of the soil and promote the growth of Asarum. At the same time, remember to drain water in the rainy season.

In fact, we still have many points to pay attention to in Asarum planting, such as the matters needing attention in weeding, the adjustment of light intensity, overwintering protective measures and pest control measures and so on. If you are interested, you can continue to follow us.
