1. Soil: soft soil is the best choice for the better growth of safflower. Its root system needs to breathe oxygen through soft soil. Alkaline soil is more suitable for its growth, so it is suggested that flower friends should choose lime or sandy soil when breeding.
2. Watering: it is a kind of plant with a large demand for water, especially when growing flower buds, it is necessary to increase the watering amount. Enough water can help its flowers bloom brightly, and also can greatly extend its flowering period. Note: there should be no water.
3. Temperature: a temperature of about 25 ℃ can make it grow better, and a mild ambient temperature can make it in a vigorous growth state, which can make it absorb nutrients in the soil, and the flowering period will also be longer. Too high temperature in summer will make it in a state of malaise, and too low temperature in winter will make it enter a period of dormancy.
4. Fertilizer: it is very important to apply fertilizer properly in addition to proper temperature if you want to have a longer flowering period. It is better to apply nitrogen fertilizer before it blooms. It is better to use nitrogen, phosphorus and potassium together in flowering period. It is better to apply fertilizer once every half a month.
The disease of safflower all over the sky is relatively less than that of insects, which can be said to be basically no, because it grows faster and takes less time to form. Insect damage is mostly aphid and spider, the symptoms of insect damage are almost the same, after the discovery of insect damage, the disease branches can be removed, using the concentration of 40% Omethoate emulsion 1000 times spray can also be used for control.
