The latest course of planting techniques and methods of cauliflower

Daylily is a perennial herb belonging to Hemerocallis of Liliaceae. It is cultivated in all parts of North and South China. It is distributed in the south of Qinling Mountains, Hunan, Jiangsu, Zhejiang, Hubei, Jiangxi, Sichuan, Gansu, Shaanxi, Jilin, Guangdong and Inner Mongolia grasslands. Sichuan Qu County is known as "the hometown of Chinese daylily." Let's take a look at the planting technology of daylily together.

The growth habits of daylily

Daylily bears barren, drought-tolerant, and has no strict requirements for soil. It can be cultivated geographically or on slopes. It has a wide range of light adaptation and can be intercropped with taller crops. The ground part is not cold-resistant, and the underground part is resistant to low temperature of-10℃. Avoid soil too wet or ponding. Seedlings began to emerge when the average temperature was above 5℃ for ten days. The optimum temperature for leaf growth was 15~20℃. The higher temperature was required for flowering, and 20~25℃ was more suitable.

Cultivars of daylily

1, early maturity type: daylily early maturity type has April flower, May flower, early morning flower, early tea mountain flower, etc.

2. Medium-mature type: The medium-mature type of day lily has mid-stage flowers of short arrows, mid-stage flowers of high arrows, Mengzi flowers, white flowers, eggplant flowers, zizi flowers, long handle flowers, black beak flowers, etc.

3. Late-maturing type: Late-maturing type of day lily includes inverted arrow flower, fine leaf flower, mid-autumn flower, large leaf flower, etc.

The reproduction method of daylily

1, ramet: daylily ramet propagation is the most commonly used method of propagation of daylily. One is to dig out all the mother plants and replant them. The other is to dig out some plants from one side of the mother plants and let them continue to grow. When digging seedlings and dividing seedlings, the roots should be injured as little as possible, and the seedlings should be planted immediately along with the digging seedlings and dividing seedlings.

2. Slicing: After harvesting daylily, dig out the roots and plants, separate them one by one according to bud pieces, remove the hair leaves around the shortened stems, leave the dead leaves, then cut off the upper ends, and then cut the rhizomes into two pieces from top to bottom. When cutting, each seedling piece needs to be equipped with seedling stems and fibrous roots. After cutting, soak and disinfect with 50% carbendazim 1200 times solution for 1~2 hours. After fishing out, use fine soil or plant ash to mix seeds and raise seedlings.

3, cuttage: day lily harvest, from the flower bud, the upper part of the bract fresh green, and bract growth point obvious, in the growth point of the upper and lower left about 15 cm cut, slightly curved flat inserted into the soil, so that the upper and lower ends buried in the soil, so that the bract has a growth point part exposed to the ground, slightly covered with fine soil protection, about 1 week later can grow roots and buds, after 1 year of cultivation, each plant tiller number of more than 12, at least 5, the next year can bloom.

4. Sowing: Daylily is artificially pollinated 10~60 minutes after flowering. The fruit bearing rate of the top branch of the main inflorescence and the second branch is the highest, and the fruit bearing rate of the first and second fruit nodes is the highest from the node position. Therefore, for the first to fourth branches, the flower buds on the 1~4 fruit nodes can be retained, the flower buds on the first and second fruit nodes can be retained on the top branch of the main inflorescence, and the rest flower buds should be thinned to concentrate nutrients on the fruits and seeds.
