Seed price and planting method of lotus root

Lotus root is the fat lower stem of Nymphaeaceae plant lotus, also known as Rong Yujie, Jade Linglong, Jade arm Dragon, etc., with high cultivation value. It was cultivated as early as 3,000 years ago in China, and now carbonized ancient lotus seeds have been found in Liaoning and Zhejiang. It can be seen that it has a long history. Let's take a look at lotus root seed prices and planting methods.

How much is the lotus root seed?

The price of lotus root seeds is about 20-30 yuan per jin, which varies greatly due to different varieties, producing areas and quality, but the production is mainly asexual reproduction, such as lotus root reproduction, terminal bud propagation and so on. Lotus root is widely cultivated in various parts of our country, which is suitable for growing in hot and rainy seasons. it is planted in the south of the Yangtze River from March to early April and in Beijing in early May. The cultivated species can be divided into three categories: lotus root, seed lotus and Hualien. Among them, lotus belongs to aquatic flowers, lotus root and seed lotus belong to aquatic vegetables.

Cultivation conditions of Lotus Root

The main results are as follows: 1. Temperature: the lotus root can germinate only when the lotus root is above 15 ℃. In the peak growth period, the temperature is 20: 30 ℃ and the water temperature is 21: 25 ℃. The temperature of lotus root is higher at the initial stage, but the temperature difference between day and night is larger in the later stage. During the dormant period, it is required to keep more than 5 ℃, and less than 5 ℃ is easy to be frozen.

2. Light: the lotus root is a light-loving plant and is not tolerant to shade. Sufficient light is required during the growth period, and the length of sunshine is not strict. Sufficient light in the early stage is beneficial to the growth of stems and leaves, while sufficient light in the later stage is beneficial to flowering, fruiting and enriching the lotus root.

3. Moisture: the water level of the lotus root is 510cm in the budding stage, 30cm and 50cm in the vigorous stage, and then gradually shallower with the flowering, fruiting and fruiting of the plant. Dormant overwintering only requires the soil to be fully moist or keep shallow water.

4. Soil: loam and clay loam, which are rich in organic matter, are the most suitable for lotus root growth. the content of organic matter should be at least 1.5%. The soil pH should be between 5.6 and 7.5, with equal emphasis on nitrogen, phosphorus and potassium.

Propagation methods of Lotus Root

1. Seed reproduction: the lotus seed is covered with a hard shell, first break the concave end of the shell, then soak it in 26-30 ℃ water to promote bud, wait for the bud to grow in water to prevent dehydration and atrophy, grow to 4 leaves and 1 whip, it can be planted in the field.

2. Whole lotus root propagation: the whole lotus root propagation is to plant the whole branch of the main lotus root together with the son lotus root and the grandson lotus root according to a certain distance between the rows and plants, the top is inserted into the mud, and the tail tip is exposed and inserted diagonally.

3. Seed lotus root reproduction: seed lotus root refers to the lateral branches on the main end, there are one node, two nodes, and four nodes of lotus root, which is related to the position of seed lotus root on the main lotus root, but no matter which section can be cut off to breed separately.

4. The propagation of lotus root head: the propagation of lotus root head is to cut off the top section of main lotus root to make seed, and it can also cut off the top section of lotus root to make seed.

5. Lotus root node propagation: lotus root node propagation is to cut 5-6 cm from the node to plant seeds, which is to use the axillary buds on the lotus root node to propagate.

6. Terminal bud propagation: terminal bud propagation is to cut off the buds at the top of the main lotus root or lotus root together with the basal node and insert them into the soft soil seedbed for propagation.

7. Lotus whip cutting: after the buds on the lotus root protrude to the branches, the two lotus whips with terminal buds are dug up and transplanted into the field.

Planting methods of Lotus Root

1. Select improved varieties: select shallow lotus root varieties with no injury and disease, good seed character, large individual, complete head, complete tail, complete terminal bud and lateral bud, stout and plump lotus root nodes, early maturity and high yield, and strive to be uniform in size.

2. Fertilization and field preparation: it is better to choose the field with fertile, deep mud layer, convenient drainage and irrigation and planting rice last year. 15 days before planting lotus root, 2000-3000 kg of mature organic fertilizer, 150 kg of cake fertilizer, 70 kg of superphosphate and 80 kg of quicklime were applied.

3. Planting time: choose sunny afternoon to arrange the lotus root seeds in the field according to the required plant spacing, and then dig trenches by hand according to the size of the lotus root, the front end of the lotus root is inclined downward, and the back end is slightly exposed to the soil, which is conducive to receiving light and air and promoting germination.

4. planting method: the mud depth is covered with mud to cover the lotus root body and lotus root bud. When planting near the ridges of the field, pay attention to all the lotus root heads turn to the heart of the field when opening ditches or ponds for planting.

5. Weeding and picking leaves: a month or so after the lotus root is planted, the withered leaves are removed when the floating leaves are withering, and before closing, they are combined with topdressing and weeding. When weeding, they should walk on both sides of the rolled leaves, and the flower branches are often bent but not cut off when they appear buds or blossoms.

6. Reasonable topdressing: 25kg / mu of high-N-P compound fertilizer was applied when 3 ~ 5 standing leaves, 30kg / mu of high-N-K compound fertilizer was applied when standing leaves were full, 15kg / mu or 10kg / mu of pure potassium fertilizer was applied when ending leaves appeared.

7. adjust the water level: the lotus root is irrigated with shallow water of about 5cm from planting to sprouting, in order to increase the ground temperature and facilitate seedling emergence. With the growth of standing leaves and branches, the water layer is gradually deepened to 15cm. Shallow water should be irrigated during lotus root formation and before harvest.

8. Straighten out the lotus root head: the lotus root vine grows rapidly around in June, and artificial vine management should be carried out. Dig up the mud and pull up the lotus root vine at noon, and then turn to the blank ground and bury it in the soil.

9. Mature harvest: most of the local upper standing leaves are withered and yellow, and the lotus root can be harvested one after another when the lotus root is fully mature. The harvest of lotus root can be divided into green lotus root and withered lotus root, the green lotus root is mostly carried out in August, and the harvest of dry lotus root is from March to April of the following year.
