Safflower planting methods and picking

Land selection and land preparation: planted in dry land or wasteland. Timely sowing: according to the local climatic conditions, we can choose spring sowing, autumn sowing, winter sowing, and then according to a certain plant spacing, each hole can sow 6-7 seeds. Field management: when the seedlings grow to 6-7 cm, the seedlings can be applied twice in the later stage. Prevention and control of diseases and insect pests: control rust, root rot, crickets, ground tigers and other diseases and insect pests. Picking: when the tip of the Corolla changes from yellow to red, it is suitable for picking, and attention should be paid to the technique when picking.

I. selection of land and land preparation

1. Carthamus tinctorius is suitable for growing in dry and fertile soil, and can generally adapt to barren soil, but it is not suitable to be planted in wet, waterlogged low-lying land, so it can be planted in dry land or wasteland.

2. The previous crops are generally wax gourd, soybean, taro and so on. After the previous crop is harvested, it is necessary to plough the land to make the soil loose and good drainage, and then apply rotten farm manure 1000kg and superphosphate 15kg per mu.

Second, sowing seeds at the right time

1. Safflower can choose spring sowing, autumn sowing and winter sowing according to local climatic conditions. Generally, Jiangsu and Zhejiang are sown in winter, while Shandong is sown in autumn, and Xinjiang and northeast cold regions are sown in spring.

2. Generally, high and low beds can be made according to the terrain, and each border can be made with two rows, and you can choose strip sowing or on-demand sowing. No matter it is strip sowing or on-demand sowing, you should sow 6-7 seeds per hole according to a certain plant spacing, then cover the soil and water it, and wait for about 14 days for seedling emergence. Generally, the amount of seed used per mu is 1.5-2.5kg.

III. Field management

1. When the seedlings grow to 6-7cm, the weak seedlings should be removed, and then the strong seedlings should be retained. Generally, 2-3 strong seedlings can be retained in each hole. If there is a lack of seedlings, it is necessary to replenish the seedlings in time.

2. When the seedlings grow 4-5 leaves, thin human manure and urine fertilizer should be irrigated once, and topdressing should be applied from the root to avoid seedling lodging, and then the second fertilizer should be applied before and after waking. 500-600kg of human manure and urine fertilizer can be applied per mu to avoid flower bud lodging.

IV. Prevention and control of diseases and insect pests

1. During the growth period, safflower is disturbed by various diseases and insect pests. The common diseases are rust, root rot, black spot, anthrax and so on, while the common pests are crickets, ground tigers, golden needle worms, grubs, mole crickets.

2. They will affect the normal growth of the plant, and even lead to the death of the plant, which is very harmful, so it is necessary to do a good job in the prevention and control of diseases and insect pests.

5. Picking

1. Generally, those sown in autumn are picked before and after the Beginning of Summer to Lesser Fullness of Grain or by the Summer Solstice. Those sown in spring are picked later than those sown in autumn. 2-3 days after the beginning of flowering, they will enter the full flowering stage, so they can be picked in time.

2. Generally speaking, it is appropriate to change the tip of the Corolla from yellow to red. If the Corolla is harvested prematurely, the Corolla will not turn red, and the quality will be poor. If it is harvested too late, the Corolla will become dark purple and will not be oily after drying.

3. Flower picking can be carried out from the dry dew in the morning to about 10:00 in the morning, and each head can be picked 2-3 times continuously, once every 1-2 days.

4. Pick 3 fingers (thumb, index finger, middle finger), or 4 fingers squeeze the Corolla and lift it up, then twist it, and you can pick and lower it into the flower basket.
