Cultivation techniques of safflower blueberry

Safflower blueberry is a deciduous tree of the genus Campanulaceae, which is native to subtropical America, Mexico and Argentina. Now it has been widely introduced and cultivated in China, often as an excellent street tree, and can also be planted in courtyards, campuses, residential areas, and so on. It is suitable for roadside and waterfront cultivation in parks, green spaces and so on. Let's take a look at the cultivation techniques of Safflower Wind Suzuki.

Growth habit

Carthamus tinctorius is native to subtropical areas and is sexually fond of high temperature. the optimum temperature for growth is 20-30 ℃. It needs to be warm and sheltered in winter. The northern part of South China is cold, rainy and humid in winter, so we should pay attention to cold damage. The sandy loam rich in organic matter is the best cultivated soil. Drainage and sunshine should be good.

Reproduction method

Camellia oleifera can be propagated by seed, cutting and striping. Because its seeds are easy to germinate. therefore, sowing is mainly used in production, seeds should be picked and sown immediately, and it will take 2-3 years from sowing, flowering to fruiting. The plants propagated by cutting and striping can blossom earlier, but the root system is underdeveloped and the trunk is not obvious.

Cultivation techniques

Carthamus tinctorius is fond of high temperature and grows well in the middle and south of South China. The cultivation site should be high, and the sunshine should be sufficient. Spring to summer is the peak growth period, applying a small amount of fertilizer once every two months, applying fertilizer two or three times a year, and fully replenishing water. Flower bud differentiation of adult plants from late autumn to spring, avoid pruning, so as not to affect flowering. Pruning and pruning should be carried out after flowering to promote lateral branches to differentiate and blossom more.

Pest control

Safflower wind chimes are vulnerable to diseases and insect pests when new leaves sprout every spring. For leaf spot disease, 50% carbendazim powder 600 times and 70% methyl topiramate powder 800 times can be sprayed alternately. The pest can be sprayed alternately with 1000 times of Wanling powder and 1000 times of Lesbon EC, once every 7-10 days, 3 times for 4 times, and the control effect is better.
