Points for attention in the planting of Shegan

Belamcanda chinensis is one of the traditional Chinese medicinal materials in China. It has no strict requirements for soil, cold and drought resistance, and is planted all over the country. However, due to improper management measures during planting, production is often reduced. Let's take a look at the precautions for planting Belamcanda chinensis.

1. Seed treatment

Belamcanda chinensis can be propagated by rhizomes and seeds. When using seeds for propagation, because the germination rate of seeds is not high, it should be treated before sowing. The specific method is as follows: first soak the seeds in clean water for 2 days, change the water once a day, stir them evenly with fine sand, put them indoors, water frequently, keep them moist, and sow most of the seeds after germination, which not only sprouts quickly and neatly, but also helps to improve the yield.

2. Intertillage and weeding

After the seedlings emerge, they should often loosen the soil and weed, so that there are no weeds in the field, so as not to occupy the nutrients and growth space of the seedlings and affect the growth of the seedlings. Weeding and loosening should be done frequently in spring, but after closing the ridge in June, do not loosen the soil and weed. At this time, soil should be cultivated in time to avoid seedling lodging. After budding, if the plants other than seeds are retained, the rest should be removed to avoid large consumption of nutrients, concentrate nutrients and roots, promote rhizome expansion, and improve yield.

3. Thinning, fixing and supplementing seedlings

The method of seed reproduction is to avoid lack of seedlings and keep strong seedlings, but too many sown, resulting in more seedlings after emergence, density, so in order to control the planting density, to timely thinning and thinning seedlings. Thinning seedlings to keep strong seedlings, between the weak seedlings, pests seedlings, thinning seedlings should not be a foot early, so as not to grow seedlings thin and weak. When the seedlings grow to 10 cm high, start to fix seedlings, generally leave 1-2 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 excellent yield, attention should be paid to the prevention and control of diseases and insect pests. The diseases of Belamcanda chinensis are mainly in the seedling stage, mainly rust damage, which will lead to large-scale death of seedlings when serious. The control method is to increase phosphorus and potassium fertilizer to enhance disease resistance, spray triadimefon liquid medicine in time when the disease occurs, once every 7-10 days, for 2-3 times continuously, and the effect is better. Insect pests are mainly aphids, cutworms, grubs, etc. They will gnaw the stems, leaves and roots of seedlings clean. Pesticides such as trichlorfon and dichlorvos can be sprayed or irrigated for control. However, attention should be paid to the concentration to avoid phytotoxicity or drug residue to seedlings.
