The Latest Technical Method Tutorial for Field Management of Safflower

Safflower is a plant of the genus Carthamus in the Asteraceae family. Its flowers, when used as medicine, have the effects of promoting blood circulation and regulating menstruation, and dispersing blood stasis and relieving pain, and are helpful in treating amenorrhea, dysmenorrhea, and traumatic injuries. At present, it is widely cultivated in Xinjiang, Tibet and other places in China. So how should field management of safflower be carried out? Let's take a look at the detailed introduction below.

1. Thinning and final thinning of seedlings

Thinning and final thinning of safflower seedlings generally need to be carried out twice. When the seedlings grow to 10 cm, thinning should be carried out once. At this time, diseased and weak seedlings are removed. For hole sowing, generally 3-4 strong seedlings are left per hole, and for drill sowing, one plant is left every 10 cm. The second thinning is the final thinning, carried out when the seedlings grow to 15 cm. Generally, 2 seedlings are left per hole, and for drill sowing, one plant is left at a spacing of 20 cm. After final thinning, frequent inspection is needed, and missing seedlings should be replanted in time when found.

2. Cultivation and weeding

Safflower needs to be cultivated three times throughout the growth period. The first two times are carried out together with thinning and final thinning, and the third time is carried out before the plants close in and form ridges. Weeding should be carried out according to field conditions. Especially for autumn-sown safflower, the seedling stage is relatively long, so weeding should be appropriately increased, and attention should be paid to earthing up to prevent seedlings from lodging.

3. Fertilizer and water management

Safflower is a fertilizer-loving plant. In addition to applying sufficient base fertilizer, reasonable topdressing should also be carried out at each growth stage so as to obtain high yield. During the seedling stage, the demand for nitrogen fertilizer is relatively high, and nitrogen fertilizer helps its stems and leaves grow, so when combining thinning and final thinning, apply 1000-1500 kg of dilute human and livestock manure water per mu. Before budding, spray 0.2% potassium dihydrogen phosphate, or 0.5% kg urea, to promote flowering, with an obvious yield-increasing effect. Safflower is drought-tolerant and afraid of waterlogging, so generally no watering is needed during the growth period. During the early growth stage, water appropriately when drought occurs, and just keep the soil moist. During the rainy season, pay attention to drainage to reduce pests and diseases.

4. Pinching

In order to increase yield, pinching should be increased during the safflower growth period to promote more branching, which has an obvious yield-increasing effect. In order to supplement the plant's nutrient consumption, fertilization is generally required after pinching. It should be noted that if the planting density is too high and the number of branches is suitable, pinching should not be carried out, so as to avoid excessive field closure, which is unfavorable to growth.
