The latest planting precautions of Shegan

Shegan is one of the traditional Chinese medicinal materials in China, which is not strict with the soil, cold and drought tolerance, and is planted all over the country. But when planting, because of some improper management measures, often lead to a reduction in production, the following with the editor to take a look at the planting points for attention.

1. Seed treatment

Shoot stem can be propagated through roots and seeds, when using seeds to propagate, because the seed germination rate is not high, so it should be treated before sowing. The specific method is to soak the seeds in clean water for 2 days, change the water once a day, then stir evenly with fine sand, put them indoors, water them frequently, keep them moist, and sow most of the seeds after sprouting, which is not only fast and neat, but also helps to increase the yield.

2. Ploughing and weeding

After emergence, the seeds should often loosen the soil and weed, so that there are no weeds in the field, so as to prevent weeds from seizing the nutrients and growth space of the seedlings and affecting the growth of the seedlings. Weed and loosen the soil frequently in spring, but do not loosen the soil and weed after the ridges are closed in June. Cultivate the soil in time so as not to lodge the seedlings. After budding, if except for the remaining plants, the rest of the buds should be removed so as not to consume a lot of nutrients, concentrate nutrients and roots, promote rhizome expansion and increase yield.

3. Interseedling, fixed seedling and supplementary seedling

The method of seed propagation is to avoid lack of seedlings and retain strong seedlings, but the sowing quantity is too much, which leads to more seedlings and high density after emergence, so it is necessary to control the planting density. It is necessary to keep strong seedlings and remove sick and weak seedlings, diseased and insect seedlings, and seedlings should be less than a foot earlier, so as to avoid weak seedling growth. When the seedlings grow to 10 cm high, they begin to fix the seedlings, generally leaving 1-2 strong seedlings per hole. After the seedlings survive, the dead seedlings should be replenished in time.

4. Pest control

In order to obtain high yield and high yield, more attention should be paid to the prevention and control of diseases and insect pests. Shoot-dried diseases are mainly in the seedling stage, mainly caused by rust, which will lead to the death of a large number of seedlings. The control method is to increase the application of phosphorus and potassium fertilizer to enhance the disease resistance, and timely spray the powder rust ning solution to prevent and cure the disease, once every 7-10 days, 2-3 times in a row, the effect is better. Insect pests are mainly aphids, ground tigers, grubs, etc., they will eat the stems, leaves and roots of the seedlings, and can be sprayed or irrigated with pesticides such as trichlorfon and dichlorvos, but pay attention to the concentration so as not to cause drug damage to the seedlings or cause drug residues.
