The latest requirements for safflower planting

Safflower has high medicinal value, which has the effect of promoting blood circulation, removing blood stasis and relieving pain. safflower oil is made from it in daily life. in addition to its strong efficacy, it is also a natural pigment and dye with broad market prospects. Widely used, its economic value is extremely high, attracting a lot of people to plant, so what conditions do you need to grow safflower? Let's take a look.

1. Temperature

Carthamus tinctorius is native to tropical regions and likes warm climate, but it is adaptable to temperature and can sprout at temperatures above 4 degrees and below 30 degrees. Its seeds begin to sprout at 5 degrees, the suitable temperature for germination is 15-25 degrees, and the most suitable temperature for plant growth is 20-25 degrees. Some varieties of safflower can even withstand a low temperature of minus 4 degrees, but if it is below 10 degrees, its buds will grow badly and affect the fruit.

2. Lighting

Safflower sex likes the environment with plenty of light, when it is mature, sufficient light will make it grow and develop well, and its grains will be fuller and fuller. Growing in a hidden environment, its buds will be stunted and, in serious cases, will lead to death. it is a long-sunshine plant, which must be given long-day sunshine to bloom normally when it blossoms, while short-day sunshine should be given to rosette leaves in rosette leaves, otherwise the rosette foliage period will be shortened, affecting yield and quality.

3. Moisture

Carthamus tinctorius should be planted in a dry environment. Safflower has developed roots and strong ability to absorb water, so it has strong drought resistance, but it is afraid of waterlogging, so it is best to regulate and control water when planting, and pay attention to timely drainage in rainy season. In addition, when the humidity is high or the soil moisture is too much, it is very easy to cause diseases, especially in the period of high temperature, when the soil is stagnant in a short time, it will also lead to plant growth hindrance and even death. Waterlogging is avoided at the flowering stage, and if there is a rainy day at the flowering stage, the pollen will be stunted, and the water content of the Corolla will be higher than the normal value, and it is very easy to join together after drying. When the fruit is ripe, if it rains, the yield of the seed will be affected, and the oil content of the seed will decrease.

4. Soil

Carthamus tinctorius is not strict with the soil and can adapt to most of the soil, but it is suitable for sandy loam with high topography, dry, good drainage and fertile soil. If the soil is too fertile, the plant is easy to grow, and it will flourish in a short time, so the ventilation and light transmittance between the plants is poor, so as to cause diseases and insect pests. The soil with low water level, too heavy soil and low-lying water is not suitable to be planted, and it is not suitable to be planted in the soil with too much salt. Too much salt in the soil will affect seed germination, yield and amino acid content.

The above is the introduction of safflower planting requirements, hope to help you, want to know more about the planting of medicinal materials, please pay attention to us.
