Techniques for growing and caring chrysanthemum plants

Please introduce to the technical people to plant and take care of chrysanthemum plants according to the new method.

1. Choose soil and soil.

Selecting the soil of Cuc Cuc has a set of horizontal roots, mainly shallow soil, from 5-20cm, there are many secondary roots. The root system is strongly developed so the soil is suitable for Cuc, which is light, porous soil, especially the new alluvial soil, the surface is flat, well drained, there is no polluted water source. Suitable pH on soil for growing Chrysanthemum from 6 -6.5.

If planting Chrysanthemum on low land, low humidity, squash, acidic soil, leading to lack of oxygen and affecting the activity of such microorganisms in the soil, the process of decomposing organic matter is slow and the root system is poorly developed. This affects the nutrient uptake of plants, leading to stunting, yellowish leaves and poor growth.

In order to plan the development of a large intensive farming area, it is necessary to select fields of> 50 hectares, tall, near the main road, or near the consumption point (urban, airport, port . ). There is an unpolluted soil and water source, convenient for investment in infrastructure (irrigation, in-field traffic, cold storage, preservation and packaging). Each household must have at least 2,000 m ² to facilitate the application of mechanized and advanced technical measures. If planted on a small scale, self-sufficient for the locality, it is necessary to select a well-lit, well-ventilated field that can be rotated with wet rice annually to eradicate pest germs.

2. Prepare soil before planting

Cultivation for Chrysanthemum needs to be plowed deeply and exposed to enhance the activity of aerobic microorganisms, enhance the air circulation in the soil, and help the soil to retain water well. Depending on the soil structure, the level of plowing varies. With alluvial soil, just plow, harrow and then up the bed. For medium soil and heavy meat, milling the soil many times. However, do not make the soil too small, break the structure of the soil. Because small soil is susceptible to clogging when rain or when watering, it loses the porosity needed.

Before planting 10-12 days, go up 20-0cm high bed, apply fertilizer. Because Cuc is grown with a high density, it is not applied in the cavity, in rows, but evenly applied on the bed surface. Liner fertilizer includes:

• Manure is item 0 tons / ha.
• Urea urea 25-0 kg / ha.
• Phosphate superficial 70-80 kg / ha.
• Potassium chloride 50-60 kg / ha.
• (1 ton of manure + 1 kg of urea nitrogen + 2.5- kg superphosphate + 1.8-2, 2 kg of potassium chloride for 1 sao of Bắc Bộ).
• The above fertilizers are mixed with soil and then covered with plastic to prevent the rain from washing off and the grass grows, waiting until it is planted.

3. Planting techniques

After good preparation of soil, basal fertilizer and seedlings that meet the planting criteria, we plant the night.

Density, distance

Depending on the characteristics of the variety, the purpose of use (for a flower or for the inflorescences), the type of soil, the level of fertilizer, intensive farming techniques that decide to plant with different densities:

- For big flowers: The planting distance is 12x15cm for tall, hard, hardy varieties, no need to support stakes and only leave 1 cotton / 1 plant (like Taiwanese, Gold Tau, CN9, CN98 varieties, CN97 - 8-12cm cotton diameter). At this distance, the density reaches 480,000 trees / ha (918,000 trees / 1 sao in the North).

- For medium flower varieties: Planted at a distance of 15x20cm with soft curved branches, playing whole bunches like white daisies, yellow limbs, purple pots, yellow stamens, yellow, silver, vegetables panicle, etc. (one body has 5 petals - diameter of 4-7cm). Density reaches 00,000 trees / ha (12,000 trees / 1 sao in the North).

- With small flower varieties: Plant with a distance of 0x40cm with raspberries, Indian red . (diameter of 2-5cm cotton). Need to press the tops several times to shape the spherical tree, play the whole tree, plant trees in pots. Planting density reaches 80,000 trees / ha (.000 trees / 1 sao in the North). Note that in conditions of growing with large distances, it is advisable to staggered each other to save space, to help plants not compete with each other.

Standard planting

The plants selected to be grown outside production must be healthy, healthy trees with developed root systems. Eliminate weak, pestilent plants. If you want to buy seedlings, you need to classify the plants. The plants have the same shape, size, root, and vitality grown into 1 bed. The trees are weaker than other beds. This is convenient for future care and harvesting.

4. How to grow

Choose a cool day, or plant it in the cool afternoon, lightly sprinkle the prepared soil then use small girders. When finished planting, take your hands and press the root. Use the original straw or litter to cover the soil and use a spray bottle or light sprayer to spray the bed. Straw straw has the effect of moisturizing the plants and has the effect of limiting the shedding of topsoil, making irrigation water easy to root down. In the early days, watering should be very gentle to avoid shaking the roots and drifting the trees. Do not let the leaves below stick to soil or mud to shoot on young leaves that clog the stomata, affect photosynthesis, respiration and water evaporation of the leaves when the tree has not regained green.
