What season is tulip suitable for planting?

Tulips can be planted according to different needs, and the best time for family planting is from mid-March to mid-May. The ornamental planting time in scenic spots is generally around September; Tulips planted in greenhouses are generally in early June, 5438+February; Generally, hydroponic tulips are changed once a month in September ~10.

The planting method of tulip should be done according to the following four steps: firstly, low temperature treatment and disinfection of tulip bulbs; Then prepare fertile and loose drainage soil, peel and plant the treated bulbs, do a good job of post-maintenance, and keep the temperature at 5 ~ 10℃ and the sunshine for a long time before tulips can be planted successfully.

1, seed ball treatment

/kloc-Before planting tulips in late October, it is necessary to treat bulbs at low temperature, and store them in the refrigerator at a low temperature of 4 ~ 9℃ to prevent bulbs from becoming moldy and rotten due to high temperature. The seeds after cold storage should be soaked in carbendazim solution for half an hour for sterilization.

2. Sandy soil

The soil for planting tulips should be fertile and loose sand with good drainage, and the soil should be slightly acidic. You can choose to mix peat soil with perlite or humus soil with vermiculite in equal amount, and then add decomposed compost to make the soil full of fertility and meet the growth needs of tulips.

3. All kinds of balls

Put the treated tulip bulbs on the prepared soil, with the top of the bulbs facing upwards, and pay attention to peeling off the taupe skin outside, so that the bulbs can germinate faster. The planting depth of the seed ball is generally 3/2 of the size of the seed ball, and then the top is covered with thin soil.

4. Post maintenance

After planting tulip bulbs, it is necessary to do a good job of later maintenance, keep the temperature between 5 ~ 10℃, and observe them in a cool and ventilated place for about 3 days. Then water the tulip bulbs to keep the soil moist, and apply a small amount of granular compound fertilizer at one time. Generally, it can successfully take root and grow new buds in about 20 days.

5. Preventive measures

(1) Low temperature environment

Tulip seeds like low temperature environment and germinate faster at low temperature. Tulip seeds generally germinate at about 5℃, and the germination rate can reach 90% at about 7 ~ 9℃. However, it should be noted that the temperature exceeding 16℃ will slow the germination of seeds, and 25℃ will stop the germination of seeds.

(2) Appropriate lighting

Tulip is a flower plant with long sunshine time. It likes light very much, and it needs sufficient light for its growth. After the seeds germinate, put their seedlings in a bright area that can accept astigmatism, let them slowly receive sunlight, carry out photosynthesis and promote their better growth.
