Cultivation Techniques of Cut Lily Flowers

(1) Land preparation

Choose loam land that is loose, fertile and well drained. During soil preparation, fully mature organic manure was applied in 5 square meters per mu, and 30~35cm was ploughed deeply. Then make the border according to the specification of wide 110~120cm and aisle 50cm, then sprinkle calcium 10~15kg, potassium sulfate 4~6kg and pentachloronitrobenzene 0.8~1.0kg on each 100m2 border, and then dig 20~30cm to make the soil loose, broken, flat, soft and fertilizer. Water thoroughly 3 days before sowing. In the plot where other bulbous flowers have been planted, 800 times triclofenac should be added to the mixture to prevent root mites.

(2) seed ball treatment

The bulbs should be treated for 30 minutes at a low temperature of 0 ℃ ~ 4 ℃ for 35 days, or for 40 days at 7 ℃ ~ 8 ℃. After breaking dormancy, soak the seeds and accelerate germination: first, use large and strong bulbs, peel off the outer layer of aging, dead or infected scales, soak the seeds with the mixture of carbendazim and methyl thiophanate for 30 minutes, rinse the seeds slightly with clean water, spread 1 layer on the ground, cover with grass to moisturize and accelerate germination, wait for germination or appear white roots.

(3) sowing

Generally sowing in late September to early October, severe frost in winter and no heating facilities should be sown in early spring.

(4) Field management

Immediately after sowing, the soil was watered thoroughly to keep the soil moist. The seedlings were unearthed about 5cm to chase dilute cake fertilizer water or dilute manure water once, and then apply dilute manure water again 15-20 days later. Spray water in the air immediately after each fertilization, and spray 0.2% potassium dihydrogen phosphate or multi-element micro-fertilizer solution every 7-10 days. Ploughing shallow and weeding in time after each watering, but not ploughing too deep. After emergence, choose a shading net with a light transmittance of 50% to 70% to shade outside or inside the shed.

(5) Disease and pest control

The common diseases of lily are gray mold, leaf spot, root rot and so on, which are mainly controlled by the above-mentioned bulb and soil disinfection. During the growing period, fungicides such as Dysenamine and carbendazim can be sprayed alternately every 7-10 days. The common pests are mainly underground pests such as root mites and aphids, which are controlled by phoxim and triclofenac.

(6) listing

It is appropriate to pick and cut the first flower when it is about to bloom. Scissors need to be sterilized with 75% alcohol, leaving the pile height is generally 10~15cm, in order to keep the ball. After harvest, clean water or deionized water is used to treat it, then finishing and packing.
