Field management techniques of safflower
It is a kind of safflower in Compositae. Its flowers have the effects of promoting blood circulation, regulating menstruation, removing blood stasis and relieving pain, and are helpful to treat amenorrhea, dysmenorrhea and traumatic injury. At present, there are a large number of plants in Xinjiang and Tibet, so how to manage safflower in the field? Let's take a look at the detailed introduction.

1, thinning seedlings and fixing seedlings

The spawning and seedling fixing of safflower usually need to be done twice. When the seedlings grow to 10 cm, they should be interplanted once. At this time, the weak seedlings will be separated. Generally, 3-4 strong seedlings are reserved for hole sowing in each hole, and 1 plant is reserved for slim sowing. The second thinning is fixed seedling, which is carried out when the seedling grows to 15 cm. Generally, 2 seedlings are left in each hole, and every 20cm 1 seedling is drilled. After the seedlings are fixed, they should be inspected frequently, and replanted in time if they are found missing.

2, intertillage weeding

In the whole growth period, safflower should be cultivated three times, the first two times between seedlings and seedlings, and the third time before closing the plants. Weeding should be carried out according to field conditions, especially sowing safflower in autumn, and the seedling stage is long. Weeding and ridging should be increased frequently to prevent seedlings from lodging.

3. Fertilizer and water management

Safflower is a fertilizer-loving plant. In addition to applying sufficient base fertilizer, it is necessary to apply topdressing reasonably in each growth period in order to obtain high yield. The demand for nitrogen fertilizer at seedling stage is too large, and nitrogen fertilizer is helpful to the growth of stems and leaves. Therefore, combined with thinning and fixing seedlings, dilute human and animal manure 1000- 1500 kg should be applied per mu. Spraying 0.2% potassium dihydrogen phosphate or 0.5%kg urea before budding can obviously promote flowering and yield increase. Safflower is drought-tolerant and afraid of waterlogging, and generally does not need watering during the growing period. Water properly at the beginning of drought to keep the soil moist. Pay attention to drainage in rainy season to reduce pests and diseases.

4. Choose your heart

In order to increase the yield, it is necessary to remove the core during the growth period of safflower and promote its multi-branching, thus obviously increasing the yield. In order to supplement the nutrient consumption of plants, it is generally necessary to remove the core after fertilization. It should be noted that if the planting density is too high and the number of branches is appropriate, it should not be picked, so as to avoid closing the field and adversely affecting growth.
