Description

Technical Field

[0001] The invention relates to the technical field of lawn planting, and in particular to a seed ecological bag and a construction method for sowing a flower-studded lawn using the same. Background Art

[0002] At present, with the acceleration of urbanization, urban desertification is aggravated, and the corresponding requirements for urban greening are also increasing. However, urban greening is mostly pure grass greening, which can only present a green visual effect. With the improvement of people's living standards, green lawns alone can no longer meet people's viewing needs. Therefore, there is an urgent need for the birth of a flower lawn. In the prior art, people mostly use potted flowers to place on the lawn to present a colorful visual effect, but this operation method is relatively cumbersome. It is necessary to first cultivate flowers in pots, and then move the flowers to the lawn after the flowers grow up, which is time-consuming and labor-intensive. Moreover, the flowers will wither after a certain period of growth and need to be manually removed and discarded, causing unnecessary urban garbage and waste of manpower. After the potted flowers are removed, part of the lawn will be exposed or withered, and it needs to be repaired manually. In view of this, the inventor provides a construction method of a flower lawn and a seed ecological bag, and uses the seed ecological bag provided by the present invention to sow a flower lawn. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a seed ecological package, comprising seed coating pills, granular organic fertilizer / BB fertilizer, bacterial fertilizer and soil remediation agent, wherein the seed coating pills: granular organic fertilizer / BB fertilizer: bacterial fertilizer: soil remediation agent = 18-22: 13-17: 4-6: 0.05-0.15; the preparation method of the seed coating pills is: first grinding the seeds, and then soaking the seeds in a potion prepared by a medicine for repelling animals and insects, a water retaining agent and an adhesive, or stirring the seeds in a wet powder prepared by the medicine.

[0004] The present invention also provides a construction method for sowing a flower-studded lawn using the seed ecological bag, sowing grass seeds and flower seeds at the same time to form a colorful flower-studded lawn, and the specific method is as follows: A construction method for a flower lawn comprises the following steps: S1. Site cleaning: In the area with stone content of 10%-60%, clean up the stones with a particle size of 5-60cm and construction waste, and clean up the soil layer with a depth of 25-35cm; S2. Rough leveling of the site: digging, filling and transporting the earth on the site to make the land level; S3. Pipeline laying: excavate the water supply trench, and compact the backfill soil after laying the pipeline; the excavation depth should take into account the thickness of the local frozen soil layer in winter, and the width of the deep excavated trench should not be less than 80cm. After the pipeline is laid, compact the backfill soil and bury it below the frozen layer; S4. Application of base fertilizer: Apply organic fertilizer (including farmyard manure, stable manure, green manure and cake fertilizer) 3-5m³ / mu, and apply compound biological organic fertilizer 30-60kg / mu and nitrogen, phosphorus and potassium compound fertilizer 15-15-15 30-35kg / mu at the same time or separately, evenly spread on the surface, and then plow into the soil to a depth of 15-20cm; make sure that the fertilizer is evenly mixed with the entire plough layer of soil to facilitate the absorption and utilization of nutrients by different root layers of crops; S5. Fine leveling of the site: after plowing and before sowing, fine leveling should be done according to the terrain; S6. Pre-sowing treatment: Before sowing, water the land to allow weeds to grow to 2-4 leaves, then use herbicides or shallow rotary tillage, and then turn the land over. When using herbicides, pay attention to safety and safety intervals; S7. Product preparation: Make the seeds into seed coating pellets, mix them in the ratio of seed coating pellets: granular organic fertilizer / BB fertilizer: bacterial fertilizer: soil repair agent = 18-22: 13-17: 4-6: 0.05-0.15, and prepare an ecological bag; S8. Sowing: Sow the eco-bag at a rate of 18-22kg / mu. If the sowing rate is too large, due to inter-species and intra-species competition, the vegetation will grow too long, the flowering period of flowers will be delayed and the flowers will be small, affecting the later landscape effect. S9. Soil covering and compaction: After sowing, cover the soil first and then compact it. Compress the topsoil of 3-5 cm to make the surface smooth. Soil covering and compaction means that after sowing, in order to make the seeds in close contact with the soil, which is conducive to water absorption and germination and prevent the soil from drying out, the surface is artificially or mechanically compacted to make the seeds absorb water quickly and germinate evenly. If compaction is not performed after covering the soil, 35-50% of the seeds will be lost. S10, surface covering: using a special covering material for covering, wherein the special covering material is any one of straw curtains, shade nets and non-woven fabrics; S11. Initial watering: water thoroughly once immediately after the surface is covered, with a watering amount of 10-14 tons / mu, and then water thoroughly every 5 days, with the water penetrating to below 15cm of the soil layer as the standard; S12. Irrigation: When the temperature is higher than 28℃ in summer, watering time is before 10 am and after 4 pm, 1-2 times a day; when the temperature is lower than 28℃ in summer, watering can be done all day, and each watering should penetrate the soil moisture by more than 15cm; when the night temperature is -3℃-3℃ in late autumn and early winter and early spring, irrigation with frozen and thawed water should be carried out; the amount of water for each irrigation of loam should not be less than 12 tons / mu, and it should be adjusted according to the soil water retention; If the water flow impacts the area due to factors such as soil quality and terrain, you can use appropriate amount of watering repeatedly until it is thoroughly watered. It is advisable to water the soil surface to keep it from drying out. After the seedlings are formed, the areas with vigorous growth need to control water, exercise plant resistance, and enhance plant root growth, so that the plants do not wilt. For loamy soil, with adequate watering and maintenance, seedlings will begin to emerge 5-7 days after sowing, and all seedlings will emerge in 20-40 days. The height can reach more than 15 cm 50 days after sowing, and the coverage can reach about 40%. Flowers will begin to bloom 60 days after sowing, and the best flower effect will be achieved in 75-80 days. S13. Topdressing: When the average plant height is greater than 10 cm, topdressing should be performed every 55-65 days; S14. Weeding: Weeding should be carried out 25-40 days after sowing; S15. Thinning and pruning: When the seedlings grow densely, thin them out and replant them in less dense areas; remove dead flowers and dead branches and leaves during the flowering period, prune to two-thirds of the plant height, sort out the dead flowers at any time, and water and fertilize in time after pruning; S16. Reseeding: For bald spots, timely reseeding should be carried out to close the bald spots and prevent weed invasion; the reseeding time is the growth period when the original plants grow poorly, reseeding annual varieties in spring and reseeding perennial varieties in autumn, and the reseeding amount is the same as the sowing amount; S17. Management in autumn and winter: Carry out fire prevention management in autumn and winter, do not clean up the dead leaves on the ground, accumulate snow in winter to preserve moisture for plants to overwinter, and prune plants in early spring of the following year.

[0005] Moreover, the herbicide in step S6 is a closed agent, and after turning the soil, at least the top 8-12 cm of soil is kept in a loose state.

[0006] Moreover, in step S7, the seed coating pills are flower field and flower sea seed coating pills and grass field and flower seed coating pills, and the preparation method is: first grind the seeds, and then soak the seeds in a potion made of an agent for repelling animals and insects, a water retaining agent, and an adhesive, or stir them in a wet powder made of the agent.

[0007] Moreover, in step S7, the seeds are mixed seeds of grass seeds and flower seeds, the grass seeds are any combination of ice grass, sheep grass, and Elymus salsa; the flower seeds are any combination of zinnia, blue flax, eight-petal plum, blue sage, blue flax, cosmos, and poppy; granular organic fertilizer / BB material refers to a granular fertilizer made by dry mixing the three nutrients of nitrogen, phosphorus, and potassium; bacterial fertilizer refers to biological fertilizer; the soil remediation agent is powdered microbial fertilizer, and the microbial fertilizer is silicate bacteria.

[0008] Moreover, the content of flower seeds in the flower field and flower sea seed coated pellets is 60%-65%, and the content of flower seeds in the grass field and flower coated pellets is 25%-35%.

[0009] Moreover, in step S8, the sowing time is from the beginning of the frost-free period to 60 days before the end of the frost-free period in each place. When the ground temperature is >10°C, the sowing is done in May-June in spring and in August in autumn.

[0010] Moreover, in step S9, the thickness of the covering soil is 0.5-2 cm for sand / loam and 0.5-1.5 cm for clay.

[0011] Moreover, in step S10, the shade net is removed when the seedlings penetrate the shade net by 1-2 cm, and the non-woven fabric is removed when the seedlings lift up the non-woven fabric. The straw mat is not removed, which plays a role in retaining water and heat, and gradually ferments into the soil in the later stage.

[0012] Moreover, in step S13, the amount of topdressing is 5-10 kg / mu of urea, and the amount of compound fertilizer applied is 25-30 kg / mu; when the growth of seedlings is poor, 10-15 kg / mu of humic acid water-soluble compound fertilizer is applied.

[0013] Moreover, in the step S14, for the grassland where the flower field and flower sea seed coated pellets are planted, 55-65 g / mu of fluazifop-butyl emulsifiable concentrate is used to weed the grass weeds, and manual weeding is required for the broad-leaved weeds.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a construction method for a flower-studded lawn, including S1 site cleaning, S2 rough site leveling, S3 pipeline laying, S4 base fertilizer application, S5 site fine leveling, S6 pre-sowing treatment, S7 product preparation, S8 sowing, S9 soil covering and compaction, S10 surface covering, S11 initial watering, S12 irrigation, S13 topdressing, S14 weeding, S15 thinning and pruning, S16 reseeding, S17 autumn and winter management, and provides a technical solution for each step to facilitate promotion.

[0015] 2. The present invention provides a seed eco-bag, which is made into seed-coated pellets and then prepared into eco-bags for planting, so that the seed survival rate is high and the plants grow vigorously.

[0016] 3. After repeated experiments, the present invention finally determined that the ecological bag should be sown at a sowing rate of 18-22kg / mu; if the sowing rate is too large, due to inter-species and intra-species competition, the vegetation will grow too long, the flowering period of flowers will be delayed and the flowers will be small, affecting the later landscape effect; if the sowing rate is too small, the vegetation will grow sparsely, affecting the appearance.

[0017] 4. The present invention can customize the combination scheme according to the flower color, flowering period, and plant shape effect to present the effect of flower sea, flower field, and grass dotted with flowers, making the planting effect richer.

[0018] 5. After sowing, the present invention covers the soil and presses the seeds to make them in close contact with the soil, which is beneficial for water absorption and germination and prevents the soil from drying out, so that the seeds can absorb water quickly and germinate evenly. During the implementation process, it was tested that if the seeds are not pressed after covering the soil, 35-50% of the seeds will be lost, resulting in economic losses and poor planting effects.
