What fertilizer do you need for laterite grown flowers that don t grow much?

More plant ash can reduce acidity. It is best to find some humus soil to mix in, otherwise the potting soil is easy to form plates, and many flower species will not live.

You can use your own organic fertilizer.

Hello, planting safflower is generally applied per mu with compound fertilizer or urea as base fertilizer, in order to ensure the emergence rate is generally not used as fertilizer as base fertilizer, it is recommended to wait until the seedlings are full and then apply ternary compound fertilizer.

1. Fertilization technology of safflower.

Safflower is drought-tolerant, salinity-tolerant, and barren-tolerant, but the planting area of safflower is generally not very fertile, so many friends think that safflower does not need to be fertilized, but this is wrong.

The demand for fertilizer for safflower depends on soil fertility, moisture, sowing period, etc., when the soil is fertile, you can not apply or less nitrogen fertilizer, generally there are medium and low fertility soils with irrigation conditions, combined with cultivating and weeding after the seedlings are set, topdressing urea 5-8 kg to lift seedlings, and applying urea 10-15 kg per mu during the pregnancy bud period.

In fields without irrigation, it is recommended that nitrogen fertilizer can be omitted, and micronutrient fertilizer can be used for safflower. It can significantly increase yield, generally at the beginning of the budding stage. Apply Haihewei potassium dihydrogen phosphate, chelated calcium fertilizer, potassium sulfate, chelated boron fertilizer, etc. per mu.

2. Sowing. 1. Period.

Adjust the sowing period of safflower is a long-day plant, the yield of different sowing dates is different, the yield of early sowing is high, and the yield of late sowing is low, so sowing should be early rather than late. Safflower seedlings are more cold-tolerant and can tolerate low temperatures, and some varieties can tolerate -15 low temperatures, so the sowing time of safflower is generally in early October, sowing in dry land in mid to late part, and digging corn feet before harvest.

2. Seed treatment.

In order to have a high yield, to ensure that the seedlings are strong and strong, soak them in water for 6-8 hours to allow them to fully absorb the water and keep the seedlings out.

The method of preparing the nutrient soil for planting flowers is as follows:

Peaty soil: garden soil: river sand: bone meal = 3:3:3:1, or peat: sandy soil: organic fertilizer: superphosphate is mixed and sieved according to 5::1.

According to the different resources of the north and the south, yellow mud can also be used: pastoral soil: humus:

Ash 2:2:1:

1 ratio, or garden soil: compost: river sand:

Grass ash is equal to 4:4:2:

1 class is acceptable.

Specific examples:

1. Kumquat is an acid-loving plant, and the potting soil should be loose and breathable and rich in humus.

The nutrient soil of kumquat flowers can be mixed in a 1:1 ratio of river sand, peat, and pine needle soil. Pine needle soil is the soil that increases the acidity of the soil, so that it does not appear that the new leaves turn yellow.

Peaty soil can be replaced with humus soil to increase nutrients. River sand can be replaced with other granular soil (slag, ceramsite) in order to increase the air permeability of the soil.

2. The requirements for potting soil are not very strict, after all, they are all varieties that take root in the south.

The formula that can be used to raise triangular plum blossoms at home: garden soil: humus soil: sand = 5:3:2; Peat:Saprolite:Sand:Perlite=5:2:2:1.

3. Milanese flowers are common in the south. In the preparation of potting soil, use 2 parts of peat soil and one part of gaza; or choose 2 parts of fertile garden soil and 2 parts of compost soil, and 1 part of Gaza; Or choose 2 parts of fertile garden soil and compost soil, 1 part of Gaza mixed mixture, and put an appropriate amount of rotting cake fertilizer at the bottom of the pot as base fertilizer.
