0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; With the change of the beautification environment, more and more places where seasonal flowers are used are also used. If you have more, you need to understand the relevant planting.
(1) Terrain finishing
1 The quality of land preparation has an important relationship with the growth of flowers. It can change the physical properties of the soil, make water and air circulate well, make the root system easy to stretch, and the softness of the soil is helpful to maintain the soil moisture, not easy to dry, can promote soil weathering and beneficial microbial activities, and is conducive to the increase of soluble nutrients. Through land preparation, the germs and pests in the soil can be turned to the surface, exposed to the air, and killed by sunlight and severe cold, which has the effect of reducing the occurrence of pests and diseases.
2 On the basis of the original mechanical leveling of the site, further use mechanical roughening in the flower planting area, because the over-dense land plots in the field are turned over deeply 40 ～ 50 cm Apply a lot of organic fertilizer.
3. The site preparation should first turn over the soil, finely crushed soil, and clean up the rubble such as stones, tiles, residual roots, broken stems and weeds. After being roughly roughened, sprinkle a relatively good organic fertilizer of no less than 5 kg / ㎡, and then use a rotary tiller to deeply turn over 30 cm. The site preparation has increased the drainage slope within the scope of the design permit to facilitate drainage and waterlogging prevention.
(2) Fixed-point pay-off
Use theodolites, measuring ropes, steel rulers and other instruments and tools to refer to the location of the completed park roads, squares and other facilities, and measure and release the contours of flower planting according to the design drawings.
Seasonal grass and flower seedlings should be hoisted when the soil is moist, so that the moist soil is attached to the root system, and root damage can be reduced when digging seedlings. If the soil is dry, it should be better irrigated 24 hours or hours before emergence. For seedlings transplanted with bare roots, dig soil with a hand shovel and gently shake off the soil clumps attached to the roots. Don't pluck or hurt fine roots, then plant. Before planting, do not expose the root to strong light or strong wind for a long time to avoid shrinkage of the fine root and affect survival. For seedlings transplanted with soil, first shovel the seedlings with a hand shovel, and then dig out seedlings from the sides and bottom to prevent the entire soil ball from breaking. Sometimes, in order to maintain water balance, some leaves can be removed to reduce transpiration. However, if too many leaves are removed, the reduction in photosynthetic area will affect the growth of new roots and seedlings.
(4) Flower selection and transportation
Seasonal flowers and plants should choose healthy and pest-free plants. Due to the poor resistance of flowers, the transportation distance needs to be shortened. At the same time, pay attention to the moisture, heat insulation, ventilation and other facilities during transportation.
