Field management technology of safflower

Carthamus tinctorius is a safflower plant of Compositae. Its flower has the effect of promoting blood circulation and regulating menstruation, dispersing stasis and relieving pain, which is helpful to treat amenorrhea, dysmenorrhea and injury caused by falling. At present, there are a large number of cultivation in China, Xizang and other places, so how to carry out field management of safflower? Let's take a look at the detailed introduction.

1. The seedlings are fixed

Safflower seedlings generally need to be divided into two stages, when the seedlings grow to 10 cm, the seedlings should be carried out once, and the sick and weak seedlings should be removed at this time. Generally, 3-4 strong seedlings are left in each hole, and one in 10 cm is left in strip sowing. The second inter-seedling is the fixed seedling, when the seedling grows to 15 cm, generally 2 seedlings are left in each hole, and one plant is sown at a distance of 20 cm. Regular inspection should be carried out after fixing seedlings, and replanting should be made in time after finding the phenomenon of lack of seedlings.

2. Ploughing and weeding

Carthamus tinctorius should be ploughed three times during the whole growth period, the first two times should be carried out together with inter-seedling, and the third time before the plant canopy was closed. Weeding should be carried out according to the field conditions, especially safflower sowing in autumn, the seedling stage is longer, it should be properly increased and often weeded, and attention should be paid to soil cultivation to avoid seedling lodging.

3. Fertilizer and water management

Carthamus tinctorius is a fertilizer-loving plant, in addition to applying sufficient base fertilizer, but also reasonable topdressing in each growth period, so as to obtain high yield. At the seedling stage, the demand for nitrogen fertilizer is too large, and nitrogen fertilizer is conducive to its stem and leaf growth, so when combining interseedling seedlings, 1000-1500 kg of sparse human and animal manure water is applied per mu. Before budding, spraying 0.2% potassium dihydrogen phosphate or 0.5 kg urea to promote flowering has an obvious yield-increasing effect. Carthamus tinctorius is resistant to drought and afraid of waterlogging, so it is generally not necessary to water in the growing period, but appropriate watering in the early stage of growth to keep the soil moist, and pay attention to drainage in the rainy season to reduce diseases and insect pests.

4. Pick the heart

In order to increase the yield, it is necessary to improve the coring of red peanut for a long time and promote its more branches, which can obviously increase the yield. In order to supplement the nutrient consumption of the plant, it is generally necessary to apply fertilizer after coring. It should be noted that if the planting density is too high, the appropriate number of branches is, do not pick the heart, so as not to close the field, which is disadvantageous to growth.
