3. Cultivation techniques of Oxalis safflower

[sowing]: safflower sorrel can also grow in general soil, but it grows fastest in fertile, loose and well-drained sandy soil. Planting should not be too deep. Apply organic fertilizer once a month during the growing period and water it in time. During the growing period, you should pay attention to watering, keep it moist, and apply fertilizer 2-3 times to keep the flowers blooming and leaves luxuriant. The growth is slow in the hot season, basically in the dormant state, should pay attention to stop fertilizing water, put in the shade, protect the summer. Fertilizer and water management should be strengthened during the peak growth period in winter and spring.

[seedling]: dig up the whole aging seedling with a shovel, gently pat off the persistent soil around the root system, and store it centrally. Dig seedlings a little further away from the plant, so as to avoid accidental injury to the bulb, and pay attention to the spade to dig straight down, not obliquely dig down, hurt the bulb.

[ramet]: the withered and residual leaves were removed and the old leaves were removed to reduce transpiration and water loss after planting. The lower old bulb should be cut off with a sharp knife, and the incision should be under the first or second new bulb, so that the seedlings with one or two new bulbs can not only remove the lower old bulb, renew and rejuvenate, but also ensure that the new plant has enough nutrients to sprout and blossom quickly. Finally, in the cut new bulb wound, dip it with fresh plant ash to prevent the wound from rotting.

[fertilization]: apply organic fertilizer in the flower bed where the aging seedlings are dug up, turn it over again and rake away the withered leaves and weeds. Generally, 0.5 to 0.8 kg / m2 of cooked cake fertilizer is applied, and appropriate phosphorus and potassium fertilizer is applied to ensure the flowering needs of safflower sorrel.

[planting]: separate the large plants of safflower sorrel, each small plant with several bulbs, and finally plant and water it. The underground stem of safflower sorrel spreads rapidly, the ramet is very easy, and can be carried out all the year round. Even in the peak flowering period, a very high survival rate can still be obtained as long as the soil at the root is pressed when planting and enough water is watered.

[pest control]: Carthamus tinctorius is easy to be damaged by red spiders. if it is not controlled in time, it can cause yellow leaves, dry up, few flowers and affect the ornamental value. Therefore, the grass can be sprayed with 1000 to 1500 times of omethoate, 0.2 to 0.3 degrees of stone sulfur mixture, and acaricides.
