? 1, biological characteristics
Like cool, humid environment, can withstand severe cold, drought, high temperature and high humidity conditions, poor growth and low yield. The soil requires the upper layer to be deep, fertile and loose, especially on sandy soil and humus soil with groundwater level. Hard clay, damp and low-lying waterlogged areas are not suitable for cultivation.
2. Cultivation techniques
Reproduce with seeds and roots. Seed propagation: It can be sown in spring, summer and autumn. Because sheep's hoof is a kind of deep-rooted plant, in order to increase the yield of roots, it is necessary to dig deep into the ground, plow to a depth of not less than 30cm, and apply sufficient base fertilizer. After ploughing, break the clods, rake them flat and make them into high ridges with a width of 60cm and a height of 25cm, and sow them in rows or holes.
In order to facilitate seedling management, drilling is better. If the newly harvested seeds are used, there is no need for any treatment. If they are soaked in warm water (below 20℃) 1d before sowing, the seedlings can emerge in advance. Sow in the north in May, and emerge in10 ~15d after sowing. The sowing amount per 1hm2 is about10.5 kg.
Cover the soil 3cm, water it in time after sowing, and keep the soil moist. After emergence, combine scarifying and weeding1~ 2 times. Root-splitting propagation: divide the root head of the mother plant into several blocks, each block has at least l-2 buds, and then carry out hole planting at the spacing of 60cmx45cm, and each 1hm2 needs about 2250kg of seed blocks.
3. Field management
After emergence, intertillage, weeding, topdressing and watering should be done in time, especially in dry weather. In addition to being used as a seed plant, the yield of roots can be improved by picking off the flower stems as early as possible. During planting,1~ 2 times of field soil cultivation should be carried out to promote the growth of roots.
