Planting method and time of bitter chrysanthemum

The planting time of bitter chrysanthemum is from March to April in spring and from September to October in autumn. Planting method: bitter chrysanthemum is suitable for planting in loose soil and slightly acidic clay rich in organic matter. the basic fertilizer can be applied to farm manure and sowed by sowing. The amount of seeds per mu is about 2 kg. When the seedlings grow to a certain height, there should be time for seedlings and replenishment of seedlings, and timely weeding, watering at the seedling stage should be dry and wet, the soil should be moist during the prosperous growth period, and moisture should be controlled in the later growth period.

1. Planting time of bitter chrysanthemum

Bitter chrysanthemum is suitable to be planted from March to April in spring or from September to October in autumn. when planting, it is necessary to select excellent varieties with high yield and disease resistance and sow in time, which is beneficial to prolong the vegetative growth period and harvest time.

Second, the planting method of bitter chrysanthemum

1. Land selection and preparation

Bitter chrysanthemum is more cold-resistant and drought-resistant, so it is suitable to be planted on hillsides, fields, forests, or near water sources at an altitude of 170-3200m. It can be planted in slightly acidic clay or sandy soil with loose soil, rich organic matter and good water and fertility conservation. The suitable soil pH value is about 4.5-8.9. After land selection, the soil is ploughed and leveled, and 1000-2000kg per mu is applied as base fertilizer, and then the border is made.

2. Sowing seeds

Can choose to plant in spring or autumn, need to select varieties with stable yield and strong disease resistance, the seeds of bitter chrysanthemum are relatively small, generally can be sown by sowing, make a shallow ditch on the border, sow the seeds evenly into the ditch, and then cover a small amount of fine soil, the depth is controlled at about 0.5-1cm, to avoid affecting seedling emergence, after soaking the soil thoroughly, gently suppress, the seed consumption per mu is about 2kg During this period, it is necessary to control the sowing density, which is beneficial to improve the quality and yield.

3. Field management

The seedlings can emerge after sowing for about 4-5 days. when the seedlings are soaked, the fields should be inspected in time, and the soil can be properly watered to keep the soil moist, so as to avoid the soil too dry and affect the growth of the seedlings, and the roots of the seedlings are relatively weak, so it is necessary to loosen the soil in time to promote the growth of the roots, and do not damage the roots when loosening the soil. when the seedlings grow to a certain height, it is necessary to carry out inter-seedling and supplementary seedlings in time, and if sick and weak seedlings are found, they should be removed. At the same time, it is also necessary to pull out weeds in the field to avoid excessive weeds and seize the nutrients of seedlings.

4. Fertilizer and water management

During this period, according to the growth of the plant, reasonable watering and fertilization can ensure the robust growth of the plant. During the seedling period, keep the soil dry and wet, do not water too much, avoid excessive growth of the seedlings, and should not be too dry. It will cause the seedlings to age, but in the vigorous season of plant growth, it is necessary to keep the soil moist. If the water supply is insufficient, it will lead to the bitter taste of bitter chrysanthemum and slightly poor taste. It is necessary to control moisture in the later stage of growth, which is beneficial to the improvement of quality and yield.
