How to grow blackberry lily (Belamcanda chinensis)? These precautions should be understood in advance
Blackberry lily, also known as mountain fan and fan grass, is one of China's traditional medicinal herbs. It has low soil requirements, is cold-resistant and drought-tolerant, and is grown all over the country. However, improper management measures during cultivation often lead to reduced yields. Let's take a look at the precautions for growing blackberry lily below.
1. Seed treatment
Blackberry lily can be propagated through rhizomes and seeds. 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, place them indoors, water frequently, and keep them moist. Once most of the seeds have sprouted, they can be sown. This not only makes seedlings emerge quickly and uniformly, but also helps increase yield.
2. Cultivation and weeding
After the seedlings emerge, loosen the soil and weed frequently to ensure no weeds in the field, so as to prevent weeds from grabbing nutrients and growing space from the seedlings and affecting seedling 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 in time to prevent the seedlings from lodging. After budding, for plants other than those kept for seed, remove the flower buds to prevent nutrients from being consumed in large amounts, concentrate nutrients in the root system, promote rhizome enlargement, and increase yield.
3. Thinning, final thinning, and replanting
The purpose of using seed propagation is to avoid missing seedlings and to retain strong seedlings, but sowing too many seeds leads to too many seedlings and too high a density after emergence. Therefore, in order to control the planting density well, thinning must be done in time. When thinning, keep strong seedlings and remove diseased, weak, and pest-damaged seedlings. Thinning should be done early, not delayed, to avoid thin and weak seedling growth. When the seedlings grow to 10 cm tall, begin final thinning, generally leaving 1-2 strong seedlings per hole. After thinning, replant dead seedlings in time.
4. Pest and disease control
To obtain high and high-quality yields, attention must be paid to pest and disease control. The diseases of blackberry lily mainly occur at the seedling stage, chiefly rust damage, which in severe cases can cause large numbers of seedlings to die. The control method is to apply more phosphorus and potassium fertilizer to enhance disease resistance, and when the disease occurs, promptly spray with triadimefon solution for control, once every 7-10 days, for 2-3 consecutive times, with good results. The main pests are aphids, cutworms, and white grubs, which can eat the stems, leaves, and roots of seedlings clean. They can be controlled by spraying or root drenching with pesticides such as trichlorfon and dichlorvos, but attention should be paid to the concentration to avoid phytotoxicity to seedlings or pesticide residues.
