The culture methods and matters needing attention of the latest Jiuli incense

Jiuli incense is an evergreen shrub plant of the genus Rutaceae, also known as chili, Jiuqiu incense, Jiushu incense, Qianlixiang, and so on. Sometimes it can grow into a small tree-like tree with beautiful trees, beautiful branches and leaves, and full-bodied flowers. In the southern region, it is often used as a hedge material, or as a decoration for flower beds and hotels, as well as bonsai materials. Let's take a look at the breeding methods and matters needing attention of Jiuli incense.

The Propagation method of Jiuli incense

1. Seed reproduction: pick full and ripe scarlet fresh fruit, rub it in clean water, remove peel and floating impurities and shrunken grains, and dry them. Seeds can be sown in both spring and autumn. Spring sowing is usually used. When the temperature is 16: 22 ℃ from March to May, it will sprout 25-35 days after sowing, and it is suitable for autumn sowing from September to early October. Before sowing, select the plot with better water and fertilizer conditions as the nursery, turn deeply, break the soil, rake flat for the border, the width of the bed is 1 to 1.2 meters. It can be broadcast or broadcast.

2. Striping propagation: in the growth period from May to June, the tree can be planted under false planting by using circular peeling and white film to take root in about 50 days. The pressing strip is easy to take root, the whisker root is well developed, and the effect is very good.

3. Grafting propagation: using Jiuli incense seedlings as rootstocks, abdominal grafting, cutting and small bud grafting can be used in the growing period. When grafting, we should pay attention to: because the cortex of Jiuli incense is particularly thick, we must peel off the cortex and show the yellow-white cambium, otherwise it is not easy to survive.

Culture method of Jiuli incense

1. Soil: Jiuli incense culture soil can be made from 7 parts of sandy loam, 1 part of fine slag, 2 parts of cake fertilizer slag (residue of cake fertilizer and water) or 5 parts of pond mud, 4 parts of peat and 1 part of river sand. Potted plants should choose sandy loam with good drainage and apply delayed organic fertilizer with more phosphorus and potassium fertilizer as base fertilizer at the bottom of the pot.

2. Fertilization: generally changing the basin once every 2 to 3 years, bone powder, phosphate fertilizer and cake fertilizer can be put on the bottom of the pot, and organic fertilizer can be applied 2 times a year to promote the growth of seedlings. Entering the growing period in May, fertilization should be increased to once a week, and the concentration of fertilizer can also be slightly higher, and it is suitable for 40% liquid fertilizer of raw juice to 60% clear water.

3. Watering: Jiuli Xiangsheng watering cake fertilizer once a month for a long time, watering requirements are generally not too strict, basin soil can be watered dry, watering should not be too much, too wet soil is easy to cause defoliation. Watering at the flowering stage should be timely and appropriate in order to ensure more flowering and fragrance.

4. Lighting: Jiuli incense likes the sun very much, but it can grow a little worse, but although it wants to appreciate the flowers, it is best to put it in a place where the sunshine is good.

5. Temperature: Jiuli incense likes to be warm and slightly resistant to cold. It grows well in the temperature range of 18-28 ℃. The overwintering temperature can not be lower than 5 ℃, but it can withstand short-term low temperature of 0 ℃.

Disease control of Jiuli incense

1. Powdery mildew: powdery mildew occurs in leaves and can be controlled by spraying azoxystrobin, triadimefon, thiophanate, etc.

2. Iron rust: iron rust is a common disease of branches and stems, which leads to the decay of branches and stems, which can be prevented by spraying triadimefon.

3. Red spider: the red spider occurs when the temperature is high, it absorbs the sap of branches and leaves, the leaves show gray spots after being killed, and when they are serious, they are withered and yellow and fall off. It can be controlled by spraying acetylide, thiazox and dacarine.

4. Scale insects: they can also cause coal fouling disease by absorbing tree sap, resulting in poor growth of trees, withered branches and leaves, early defoliation, which can be killed by dimethoate, trichlorfon and dichlorvos besides being wiped out manually.

5. Longicorn beetles: longicorn beetles do great harm to plants, and adults can be removed manually, or stone-sulfur mixture can be applied for control.

6. Beetles: during the growth of young leaves, you can spray 800x trichlorfon aqueous solution or 1000 times once purified aqueous solution for control. Family potted Jiuli incense can be controlled by artificial capture, and the captured pests can be scalded to death with hot water.

7. Leaf roll moth: during the growth of tender leaves, 1500 times pure water solution of aphid lice, or 1500 times water solution of great meritorious heroes, or 1500 times an Lubao water solution can be sprayed once to control and kill larvae.

Matters needing attention in Jiuli incense culture

1. Jiulixiang culture basin soil should choose fertile soil, change the basin every spring, add appropriate amount of phosphorus and potassium fertilizer to the bottom of the basin or use rotten barnyard manure as base fertilizer.

2. Jiuli incense culture management should be based on the "three fears" of Jiuli incense, that is, those who are afraid of dampness, exposure and cold, and take corresponding measures to avoid watering too much, but like moist air, exposure should be placed in a semi-shady place, and when the winter temperature is lower than 5 ℃, it should be moved indoors.

3. Jiulixiang culture uses more organic fertilizer and less chemical fertilizer when fertilizing. You can choose the rotten cake fertilizer, apply the broken cake fertilizer directly to the soil, or soak in water.

4. Jiuli incense needs pruning and pruning in time to remove overdense branches, long branches and overlapping branches, which is beneficial to flower and fruit flourishing, and the pruning time is better before spring flowering and summer and autumn.

5. Mixed nitrogen, phosphorus and potassium fertilizer should be applied during the growth period of Jiulixiang, not partial application of nitrogen fertilizer. Apply more phosphorus and potassium fertilizer before flowering and budding. If there is too much nitrogen fertilizer and lack of phosphorus and potassium fertilizer, the branches and leaves are easy to grow without budding and blooming. When pregnant buds should be properly less watering, in order to facilitate pregnancy buds.

6. Jiuli incense plants gradually stop growing after the autumn is cool, so they should begin to reduce the number of watering. Generally, they can be watered once every other day, and fertilization can also be gradually stopped. By the end of September, it should be moved indoors and kept in a sunny place for maintenance. At this time, watering should be greatly reduced, usually once every 3-4 days, and fertilizer should be stopped completely.

7. Jiulixiang should prevent the plant from frost damage in winter, the lowest indoor temperature should be maintained above 10 ℃, and watering should be strictly controlled. If the basin soil is not dry, it is appropriate to keep it a little dry.

8. Jiuli incense can be changed every 2012. the basin soil is fully mixed with 50% needle rotten leaf soil, 20% garden soil, 20% fine yellow sand and 10% compost soil. Changing the basin can be carried out in April or May in spring, and sufficient mature basic fertilizer should be applied at the bottom of the basin when changing the basin.
