What are the key points to note when growing blackberry lily (Belamcanda chinensis)? A full breakdown of the latest essentials

Blackberry lily, also known as mountain fan and fan grass, is one of China's traditional medicinal herbs. It is not demanding about soil and tolerates cold and drought, and it is grown all over the country. However, improper management during cultivation often leads to reduced yields. Below, follow the editor to learn about the key points to note when growing blackberry lily.

1. Seed treatment

Blackberry lily can be propagated by rhizome and by seed. When using seed propagation, because the seed germination rate is not high, the seeds must be treated before sowing. The specific method is: first soak the seeds in clean water for 2 days, changing the water once a day, then mix them evenly with fine sand and place them indoors, watering frequently to keep them moist. Once most of the seeds have sprouted, they can be sown. This not only produces fast and uniform emergence, but also helps increase yield.

2. Cultivation and weeding

After the seedlings emerge, loosen the soil and weed frequently, keeping the field free of weeds, so that weeds do not seize nutrients and growing space from the seedlings and affect their growth. In spring, weed and loosen the soil frequently, but after the rows close in June, do not loosen the soil or weed; instead, earth up promptly to prevent the seedlings from lodging. After budding, except for plants kept for seed, remove the flower buds from the rest, so that nutrients are not consumed in large amounts, concentrating nutrients in the roots and rhizomes to promote rhizome enlargement and increase yield.

3. Thinning, final thinning, and replanting

The purpose of using seed propagation is to avoid gaps in the stand and to keep strong seedlings, but sowing too many seeds leads to many seedlings and high density after emergence. Therefore, to control planting density well, thin the seedlings in time. When thinning, keep the strong seedlings and remove diseased, weak, and pest-damaged seedlings. Thinning should be done early rather than delayed, so the seedlings do not grow thin and weak. When the seedlings reach 10 cm tall, begin final thinning, generally leaving 1-2 strong seedlings per hole. After the thinned seedlings become established, replant any dead seedlings promptly.

4. Pest and disease control

To achieve high and quality yields, attention must be paid to pest and disease control. The diseases of blackberry lily occur mainly at the seedling stage, chiefly rust, which in severe cases causes large numbers of seedlings to die. The control method is to apply more phosphorus and potassium fertilizer to strengthen disease resistance, and when disease occurs, promptly spray with triadimefon solution, once every 7-10 days, for 2-3 consecutive times, which gives good results. The main insect pests are aphids, cutworms, and white grubs, which eat the stems, leaves, and roots of the seedlings clean. They can be controlled by spraying or drenching the roots with pesticides such as trichlorfon and dichlorvos, but pay attention to the concentration, so as not to cause phytotoxicity to the seedlings or leave pesticide residues.
