Cultivation methods and matters needing attention of orange flower pot cultivation

1. Culture methods:

1. Watering. Keep the basin soil moist, water should be watered thoroughly, and it is better to have water seeping out from the drainage hole at the bottom of the basin. At the same time, avoid stagnant water, timely drainage, otherwise it is easy to cause rotten roots.

2. Fertilization. Adhering to the principle of "frequent application and thin application", mature liquid fertilizer should be applied before plant germination, and then liquid fertilizer should be applied every 7-10 times, mainly nitrogen fertilizer, in order to promote its growth and produce more spring shoots. In the orange blossom growth period, you can sprinkle some cake fertilizer to the basin to enhance fertility. After autumn, gradually reduce fertilization to avoid overnutrition, resulting in fruit drop. Fertilization is strictly controlled in autumn and winter.

3. Shaping and pruning. Potted orange blossoms should be pruned and thinned in time because of their limited nutrients. Generally every 2 years need to change the basin to change soil, combined with pruning.

2. points for attention:

In the case of no frost damage in winter, generally do not overwinter indoors, let it hibernate naturally outside. In order to prevent frost damage, the soil can be watered once before freezing, and then the whole container can be wrapped with a straw bag to protect against cold, or ditches can be dug and buried.

What if the leaves of orange blossoms turn yellow

1. The yellowing of orange leaves after reasonable watering may be caused by too hot weather and too much water loss. At this time, you should appropriately increase the amount of water, you can water once in the morning and once in the evening, and pay attention to the amount of water not to be too much. In addition, you can usually spray water to the leaves, or sprinkle water around the basin to increase the humidity of the air.

2. Correct fertilization lack of nitrogen fertilizer or boron fertilizer will make the leaves of orange trees yellow, so fertilizers containing nitrogen or boron should be applied at this time. Less nitrogen can be applied to farm manure or spraying urea, boric acid can be applied to boron deficiency, and boric acid solution is also a good choice.

3. Changing the soil quality of the orange tree is more suitable to survive in the acidic soil, if the soil is alkaline, it may cause its leaves to turn yellow or even lose their leaves. You can water it with a little beer, but be careful not to mix it too much. In addition, when choosing soil, you should choose fertile soil with better ventilation. If the soil is dug out from the wild, it should be exposed to the sun.

Common insect pests of orange blossom and their control

1. Leaf miner. Control method: a large number of new shoots germinated in spring. When the shoot length is less than 1cm, the biological pesticide Bacillus thuringiensis 100x solution can be used for spray control, and the effect is very good, and the fruit can also be sprayed with omethoate EC 1000 times.

2. Full claw concealment. Prevention and control methods: during the occurrence period, it can be sprayed with 0.3 degree stone sulfur mixture or 1000 times of 40% dimethoate emulsion or 70 times of 20% acarate wettable powder, once every half month, 3-4 times, and the effect is remarkable.

3. Jade belt Phoenix butterfly. Control methods: the pupae found to be overwintering on the plant in winter should be removed manually in time. The larvae of Phoenix butterflies are large and easy to be found, and can be caught and killed in time when they occur sporadically. During the larval occurrence period, it can be sprayed with 800 times of 90% trichlorfon.

In fact, it is not difficult to cultivate orange flowers, mainly to master its growth habits, and then start with its growth habits. In breeding, we must pay attention to the light and soil, and then timely management of fertilizer and water, so that orange blossoms can grow better.
