Crimson saffron, also known as saffron, saffron, sarsaparilla, poland, etc., is a perennial herb of the iris family. In the past, many farmers had planted safflower, but because they did not understand scientific management, the safflower bulbs were longer and smaller, the flowers were opened more and more, and the yield per mu was getting lower and lower. Most of them abandoned cultivation due to no benefit. After more than ten years of planting experiments, Henan Agricultural University and relevant units have shown that as long as the scientific management of the saffron is sufficient, the basal fertiliser should be applied, and the bulbs of more than 8 grams should be selected (Note: the bulbs below 8 grams do not bloom), and the budding technique is adopted. , Appropriate amount of hormones, while increasing the amount of bulbs planted, will ensure the high yield and stable yield of safflower. Planting one mus of saffron, the average mu of 1-2 kg of dried flowers, bulbs of 600-1000 kg, the domestic market price of saffron 4000-7000 yuan / kg, the international market price of 2,000 US dollars / kg, the market price of bulbs 40-50 Yuan/kg. The annual income of a safflower safflower is about 1 million yuan. After the second year, there is no investment in bulbs, and the benefit is greatly increased.
In the open cultivation of saffron in September, the north should be sooner rather than later. Early cultivation, early emergence, first hair root, after germination. Indoor flowering bulbs are planted in Daejeon immediately after picking 80% of flowers indoors from late October to mid-November. The saffron grows in Daejeon from mid-November to early May. The time is approximately six months. During this period, the following work should be done:
About 20 days after the scientific supply of fertilizer, about 2000 kilograms of livestock and manure will be poured into the water per acre. Under drought conditions, it will be more watery. The saffron will return to green in mid-February of next year, and 300-400 kilograms of human feces will be applied per mu. Since March, the production of safflower has entered a vigorous stage. 0.2% of monobasic potassium phosphate is sprayed every 10 days and sprayed 2-3 times.
It is necessary to regulate and control the water. If the safflowers do not have sufficient moisture in the soil after the next seeding, they must be fully watered. The northern region should be kept dry and the water should be irrigated before entering the winter. In the following year, it should be irrigated again to meet the growing needs.
Should pay attention to anti-frozen Baomiao Although safflower is a cold-resistant plant, but encountered cold temperatures of minus 20 degrees to 10 degrees to take antifreeze measures, covered with a layer of hay in the gills, covered with plastic film, take the wind barrier.
If the lateral buds have been removed when the side bud bulbs are removed, if they are found in the field, if they are found to grow, they will be inserted into the soil with a knife and removed.
Good control of pests and diseases The entire growth period of saffron is basically low temperature, with few pests and diseases, and it is usually prevented during rejuvenation. In case of rot disease, pour with 5% of the bacillus special 800 times liquid. If there are locusts, use 10% of Dimethoate Emulsion 2000 times spray. At the same time, we must do a good job of rat-biting bulbs and field rabbits to eat saffron leaves.
