Safflower is a cold-tolerant plant, and it should follow natural laws in the production process, select the area that is most suitable for its growth, give full play to its potential for yield increase, and trade off the largest gain with lower input. Therefore, the following links should be grasped when planting safflower. The quality of fine plowing ploughs determines the quality of sowing, and ultimately affects the increase in output. Seed treatment of safflower is susceptible to rust and root rot when it encounters suitable temperature and humidity after emergence, resulting in a reduction in the number of harvested plants and affecting yield. Severe rust will cause the leaves of all fields to die and reduce the grain production. Caused by the disease is the seed bacteria, soil bacteria and airborne. In order to reduce the incidence of safflower, seed treatment should be carried out to prevent seedling infection. The method is as follows: 50% of the enemy's wettable powder is used to seed the seeds with 0.5% of the seed amount. Early time sowing, reasonable close planting, diligent cultivating safflower is a cold-resistant crop, early sowing can extend the development stage, is conducive to the development of the root system, cultivating strong seedlings, and is very effective in increasing yield. Safflower sprouted at 4 to 5°C, and was able to withstand low temperatures of -6°C during the seedling stage. Reasonable dense planting is an effective measure to ensure high yields. Plants with too high a density are susceptible to development due to their delicate development, while those that are too dilute do not meet the expected yield. Therefore, an interval of 8 to 10 cm is preferable for each plant. The cultivator is conducive to raising the ground temperature, keeping grasshoppers, and weeding. It is conducive to the development of roots, seedlings, and disease resistance.
