Almond cultivation methods and precautions

1. Maintenance methods

1. Temperature: It has a very strong cold resistance. It will not be frozen when the temperature is below minus 20 degrees, but it will not grow. Its growth state is best when the temperature is around 30 degrees. It is also very heat-resistant. It will continue to grow when the temperature is above 40 degrees. However, if the temperature is too high, it will affect the fruit setting rate. Therefore, when the temperature is above 35 degrees, you should consider cooling it.

2. Watering: It has good drought resistance and can continue to grow even when the moisture content of the surface soil drops to 5%. It is very sensitive to water. When there is abundant rainfall and it is distributed reasonably, it will grow very well and its yield will increase significantly. If the plant is in a dry environment for a long time, the quality of the almonds will decline. If it doesn't rain for more than two months, you need to water it once a week.

3. Fertilization: The first fertilization is in early spring or late winter, and nitrogen fertilizer is the main fertilizer; the second fertilization is during the expansion period of plant fruiting, and nitrogen and potassium fertilizers are the main fertilizers; the third fertilization is after the fruit harvest, and animal manure is the main fertilizer. When fertilizing, it is combined with deep plowing in autumn. In order to improve the utilization rate of fertilizers, fertilization should be combined with spraying of new lipid film. At the same time, the plants need to be watered, which can also improve the utilization rate of fertilizers.

4. Light: It is a light-loving tree species, and sufficient sunlight plays a vital role in the fruit setting rate of the plant. If there is sufficient light, the plant will grow well and the fruit quality will be good; if there is insufficient light, the plant will be stunted. If possible, the daily light time should exceed six hours.

2. Breeding techniques

1. Reproduction: It can be propagated by grafting. Grafting propagation mainly uses bud grafting, and T-shaped bud grafting is the most common method. Put the leather tube over the bud eye of the rootstock, tighten it a little, and there is no need to tie it after putting it on. Bud grafting is usually done between May and August, because the plants are most active at this time and the success rate of grafting is the highest at this time.

2. Pruning: Pruning is required once during the growing season, and bad branches should be cut off from flowering to autumn leaf fall.

3. Problem Diagnosis

1. Pests: The plant is easily infected by peach aphids, and the infected branches need to be sprayed with dimethoate, usually once a week, and a course of treatment is three times.

2. Diseases: The plant is susceptible to root rot, which can cause the roots of the plant to rot. In severe cases, the plant will die. It needs to be treated by spraying with carbendazim wettable powder.
