Chrysanthemum brain cultivation

Chrysanthemum brain is also called roadside yellow, chrysanthemum leaf, which is a closely related species of Asteraceae wild chrysanthemum. It is cold and heat-tolerant, and after winter winter, the roots and underground stolons still survive. In the first year after winter, the new plant germinates in the first year. The adult plants have certain heat resistance and can grow normally in summer. Kinds of chrysanthemum brain should master the following points:
A good selection of chrysanthemum brain is divided into two types of leaf and leaflet according to leaf size. The large-leaved species is also known as the chrysanthemum brain. The leaves are oval, the tip is relatively blunt, the edge of the leaf is not sharp and shallow, the quality is good, and the yield is high. The leaflets of the leaflets are smaller, the leaf margins are deep and the petiole is often lavender, the tip is more pointed, the yield is low, and the quality is poor, but the adaptability is strong.
The second sowing and seedling chrysanthemum brain can be used as the annual culture can also be used for perennial cultivation, generally with seed breeding, can also be bred or cutting propagation, a number of times the harvest. When seeds are used for breeding, 0.5 kg per acre is used and sown in early April. The soil should be loose, finely crushed, sowed or sowed. Before the emergence of the soil to keep moist, seedling height 5 cm between the seedlings, and with the water topdressing available nitrogen fertilizer. When the seedling height is 10-15 cm, it begins to be cut with scissors. After two harvests, the stems are thick and can be cut with a knife. When transplanting seedlings, it is best to plant seedlings in the spring with impotence or plastic sheds. When the seedling height is 6-8 centimeters, it is planted at a distance of 10-15 centimeters and 4-5 strains each time. Removed after harvesting from September to October.
Plants that have been seeded or transplanted with three-year-old cultivation methods are allowed to grow naturally after the end of harvesting, or to cover the cold-proof winters before winter. In early spring, take a small shed to increase the temperature and promote early germination. Cut off the dead branches after germination. In the spring, the dry branches are cut off and fertilizers are applied in time. In particular, it is necessary to diligently water the plants in the summer. Usually, they can be harvested continuously for 3-4 years and then updated again.
Four cuttings and ramets Chrysanthemum brains can be cut and propagated throughout the whole growth period. Among them, the survival rate from May to June is the highest. The method of cutting seedlings is to use a mixture of clean sandy loam, river sand, and peat, or directly apply water to sandy loam soil. Chrysanthemum brain shoots 6-7 cm long, basal 2-3 leaves removed, inserted in bed soil, deep 3-4 cm. Shading, moisturizing, about 15 days to survive, live after the transplant field. Most of the vegetative propagation has been thawed in the spring season. The sprouts have just been grown: the old roots of the chrysanthemums are cut open to expose the root neck, and part of the old roots are cut and planted along with the lateral buds on the roots. water. Dividing plants, plants grow fast, but the amount of seedlings is small, suitable for small area breeding.
5. Timely harvesting and retention of chrysanthemum brains with tender stems and leaves for food, such as from the beginning of May, when the plant height is 10-15 cm, the young shoots are cut and harvested every 15 days till September-October. When buds bloom, they stop. After harvesting, it is bundled into small bundles. When harvesting, pay attention to the height of stubble, keep 3–5 cm high in spring and 6–10 cm in autumn. 4000-5000 kg per mu. When the seeds are left, they will not be harvested after the summer and let them grow naturally. When the seeds ripen in December, they will be harvested, dried and threshed, and the harvested seeds will be about 10 kg.
Six diseases and insect pests have less control of chrysanthemum encephalopathy, and they are harmed by locusts during drought. They can be sprayed and treated with 40% dimethoate emulsion 1000 times. Medication recovery period not less than 10 days.
