1, the growth environment of chrysanthemum morifolium
Saussurea involucrata is an annual plant, which adapts to the ambient temperature range of 15℃~30℃, and likes fields with sufficient sunlight, fertile soil and loose permeability. Chrysanthemum morifolium likes to moisten the soil, but it is not resistant to waterlogging. Waterlogged land and waterlogged land cannot be cultivated, so we should choose fields with high terrain and smooth drainage and irrigation. Chrysanthemum morifolium is a kind of crop that especially likes rural fertilizer. Generally, fully decomposed farmyard manure is applied before planting, and nitrogen, phosphorus and potassium compound fertilizer can be used as base fertilizer if there is no farmyard manure.
2. Dry the ground in advance
When planting crops, it is best to dig deep in the sun one month in advance, or dig deep in winter, seize the sunny day to plow and use the sun's light to kill germs and pests contained in the soil. This is a good method most often cultivated in ancient times. Because there were no chemical fertilizers and pesticides before, even good food for people was very scarce. Usually, germs were killed by drying the ground to improve the fertility of the soil. In winter, the soil will have a good harvest next year. Therefore, turning over the fields in advance can prevent the occurrence of pests and diseases, and the soil is loose and permeable, which is very conducive to the rooting and germination of crops in the future.
3, the most meticulous soil preparation before sowing
A few days before sowing, Chrysanthemum morifolium L. is carefully prepared. More than 3,000 kg of decomposed and fermented farmyard compost is put into each mu. The more decomposed farmyard manure, the better. 50 kg of NPK compound fertilizer can also be used. The fertilizer and soil will be evenly and finely smashed by harrow cultivator or manual ploughing, and made into flat plots, with the width and width determined by themselves, and the depth of the pedestrian ditch will be 25 cm.
4, the best sowing time
Chrysanthemum morifolium is usually sown in spring and autumn, and the best sowing is in spring, when there is enough rain and the temperature is suitable, which is very beneficial to the germination and growth of chrysanthemum morifolium. The most common sowing method of chrysanthemum morifolium is direct seeding. The seeds are aired for several hours, soaked in clear water for several hours, so that the seeds can absorb enough water, and then taken out to dry and sow immediately. Sow the seeds evenly into the soil. If you have plant ash at home, you can mix the seeds and sow them together. The effect is very good. After sowing, sprinkle a thin layer of fine soil on the seeds. Then, water is poured once, and the soil can be moistened thoroughly. Generally, seedlings can emerge in 3-5 days. Generally, small water is poured at seedling stage, and small water is poured when the soil is dry.
5. Water and fertilizer pipe for Artemisia selengensis interplanting
When the seedlings of Chrysanthemum morifolium grow to 5 cm high, it is necessary to interval the seedlings once, so as to reduce the overgrown seedlings of Chrysanthemum morifolium, so that the seedlings can be ventilated, breathable and light-permeable. Like some farmers who plant less, they only grow them for themselves, and most of them choose to harvest them many times. Its density can be moderately wide, with a spacing of 20 cm and a spacing of 25 cm. Professional growers are all harvested at one time, and they can encrypt points appropriately. Chrysanthemum morifolium for water and fertilizer management is relatively simple, as long as the soil is kept wet, drainage work should be done when there is a lot of rain to prevent water accumulation. However, in the case of applying sole fertilizer in fertilization, the quick-acting nitrogen fertilizer should be applied again after Artemisia selengensis grows to 10 cm height, and nitrogen fertilizer 10 kg and phosphorus and potassium 2 kg should be applied to every kilo of decomposed manure. If fertilizer is directly applied, nitrogen fertilizer 20 kg and phosphorus and potassium 5 kg should be used per mu. For farmers with less cultivation, there is enough decomposed manure in their homes, and it can be watered only once a week, and the effect is also very good.
6. Prevention of pests and diseases
Diseases and insect pests rarely occur in Chrysanthemum morifolium. Generally, there will be no pests in this vegetable with strong smell, but as long as the diseases are well managed, the diseases will not occur if planted according to the above methods. In the process of managing the growth of chrysanthemum morifolium, it is necessary to pay attention to the situation of weeds in the field. If weeds are found, they need to be pulled out in time to avoid the competition between weeds and chrysanthemum morifolium for nutrients.
Conclusion; The above content is about the process of cultivating Chrysanthemum morifolium. You can also cultivate Chrysanthemum morifolium with high yield as long as you sun the ground in advance, sow in time and manage water and fertilizer.
