How can we raise the rich tree in the latest?

The rich tree is very popular with people, and how to raise it well has become a problem that people often pay attention to, but many people do not understand its habits and are careless in management, resulting in diseases such as withered branches and leaves, stem rot and so on. How on earth should the rich tree be maintained?

To understand the habit of making a fortune tree.

The rich tree likes light and shade, likes water and fertilizer, tolerates drought and barren, likes high temperature and humidity, avoids low temperature frost and frost injury, the suitable growth temperature is 15 ℃ to 30 ℃, and the low temperature branches below 0 ℃ can produce frost injury.

The daily maintenance and management of the rich tree should be fine.

1. Spray regularly, check more frequently, and find that diseases and insect pests are dealt with immediately: common diseases of rich trees are: leaf spot, branch blight, stem rot, root rot and so on. Common pests include aphids, white planthoppers and some pests that eat stems and roots, which should be prevented in daily management. For example, 1% half-dose Bordeaux solution, 70% methyl topiramate wettable powder 700-800 times to prevent leaf spot disease, irrigating Shuangling-manganese-zinc wettable powder 500-600 times solution, 70% ethyl manganese wettable powder 300-400 times solution to prevent stem rot, branch blight, root rot and other diseases; pot application of 3% furan granules 2 to 5 g or 15% 0.g5 to 0.7 g to control various pests. Medication interval is generally 7 to 15 days, each dosage should be appropriate, in order to prevent drug damage.

2. The cultivation substrate should be loose and permeable.

3. Strict watering and fertilizer application: under normal circumstances, watering should be done once a day in summer, once every 3 to 5 days in spring and autumn, and once every 5 days in winter. Combined with watering, 3% to 5% urea water can be applied every summer. 3% to 6% potassium dihydrogen phosphate solution can be applied every semimonthly; 3% to 6% potassium dihydrogen phosphate solution is applied every spring, autumn and winter, and 3% to 5% urea water is applied every semimonthly.

4. Anti-freezing injury in autumn, winter and spring: in late summer and early autumn, rich trees enter the growing period, when the amount of nitrogen fertilizer can be increased, and gradually decreased in October, while the use of phosphorus and potassium fertilizer will be increased, and nitrogen fertilizer will be stopped 20 days before frost. after that, 3% potassium dihydrogen phosphate solution was sprayed every 3 days to enhance its adaptability to low temperature and adverse environment. Warm measures were taken when the minimum temperature appeared at 4 ℃ during the day, and phosphorus and potassium fertilizer was still applied to warm the climate in spring, while the amount of available nitrogen fertilizer was gradually increased, and the use of phosphorus and potassium fertilizer was reduced in early May.

Remedial measures for branches caused by chilling injury

The sudden drop of temperature above 0 ℃ can cause chilling injury, and when the temperature drops to 3-4 ℃ in autumn and winter or in winter and spring, freezing injury occurs in leaves. Branches and roots below 0 ℃ should be moved to a warm place as soon as the symptoms appear. If the leaves are damaged, the leaves can be sprayed with 5-15ppm butyl naphthalene acetate and gibberellin solution of 10ppm, and the roots can be irrigated with 10-3ppm naphthalene acetic acid solution, vB20.2mg/ plant and vB20.3mg/ plant solution. This treatment should be done every 3 days, and after the tender leaves grow, it should be changed to once every 7 days, for a total of five to six times. If the branches and stems have been damaged, they should be re-cut (usually cut off the healthy part 10 to 20cm) and scorched and cut at the same time to prevent bacterial infection, then irrigate the roots every 5 to 7 days with the above-mentioned root irrigation agents, or dissolve 3G aspirin in 10-4ppm naphthalene acetic acid 500ml solution and slowly inject into the body through the infusion belt until the new buds sprout, during which the roots can be irrigated 2 to 3 times with 70% ethyl manganese wettable powder to prevent root rot. When it is found that the root is damaged, the light one can pour 200 times of 70% ethyl manganese wettable powder solution, and then put it in a warm and dry place; for heavy ones, remove the basin, rinse the root clean, dig up the damaged part, then immerse the root in 200 times 70% ethyl manganese wettable powder solution for 4 to 5 hours, take out and insert it into the sand bed, wait for the new root to grow and put it into the basin again.

Control measures of other diseases

When it is found that the branch is withered and the upper stem becomes soft, the diseased branch and stem should be re-cut to prevent bacteria from infiltrating with the tissue liquid, and at the same time, 70% ethyl manganese 200 to 300 times solution should be used to irrigate the root. If the stem appears disease spot or root local rot, you can scrape off the disease spot and part of the healthy tissue. Then apply Pikangwang ointment on the sores, and then irrigate with 70% ethyl manganese wettable powder 200 times.
