What are the latest precautions for tamarind cultivation
Tamarind, also called tamarind bean and sour fruit, is the fruit of an evergreen large tree that grows in tropical and subtropical regions. Tamarind is not very common in our daily lives, mainly because tamarind cultivation is not large in scale and has a long growth cycle, generally ten years of growth, ten years of flowering, and ten years of fruiting, making it a very rare medicinal material. So today the editor brings you the precautions for tamarind cultivation, and friends who are interested can take a careful look.
1. Planting environment
Tamarind has relatively high requirements for the planting environment, and we need to decide based on its growth characteristics. Tamarind is cold-tolerant and light-loving. The annual average temperature of the planting site should be maintained between 18 and 25 degrees, among which the average minimum temperature cannot be lower than 10 degrees, and the minimum temperature month cannot be lower than 3 degrees. Second, the planting site should have low rainfall, generally preferably intermittent drought and rainfall, and there should be no frost weather. It is suitable for growing in acidic loam.
2. Seed treatment
Before sowing, we need to treat the tamarind seeds, because their seed coats are relatively hard, their absorbency is poor, and the germination rate is low. For tamarind seeds, we usually use the method of soaking seeds in warm water, at a temperature of about 40 to 50 degrees, and the soaking time is two days. During the soaking process, we should constantly stir the seeds so that they are heated and absorb evenly, which can improve the speed of seed emergence and the emergence rate.
3. Scientific water and fertilizer
The growth of tamarind trees does not require much water, so under normal circumstances there is no need for excessive watering. During the young tree stage and the growth period of tamarind trees, we mainly use nitrogen fertilizer to promote the growth of tamarind trees, applying about twice a year, and the amount of fertilizer also increases year by year. Adult tamarind trees have relatively large fertilizer requirements, mainly during the flowering and fruiting periods, so we need to fertilize according to their growth characteristics. During the flowering period, urea is mainly used, combined with compound fertilizer, while during the fruiting period, calcium fertilizer should be used together to promote the enlargement of the fruit.
4. Pruning and mounding
When planting tamarind, we should also pay attention to tree shape pruning and dwarfing the tamarind trees, so as to facilitate later management and harvesting. Pruning of tamarind trees generally starts from the young tree stage. At the beginning, only one or two main branches are retained, and later the number of main trunks and secondary and tertiary trunks is gradually increased, gradually expanding the crown and trimming the crown. Fruiting trees, however, need to have dead branches, diseased branches, old branches, insect-damaged branches, and dense branches thinned out. In addition, after tamarind has been planted for two years, we need to dig pits and expand the holes, which can not only improve the soil but also promote the expansion of the tamarind tree root system, which is what we call mounding.
5. Weeding and disease prevention
Weeding is also very important in the tamarind cultivation process, especially in some areas with poor soil. In order to reduce nutrient consumption, we need to weed at least two to three times each year, especially in July and August each year. Also, attention should be paid to the prevention and control of pests and diseases, among which the main ones are powdery mildew, leaf spot, and blue-green weevils and green scarab beetles. We can use wettable powder Baifenling, wettable powder methyl thiophanate, and omethoate emulsifiable concentrate respectively for prevention and control.
The points summarized by the editor above are the most common issues we encounter when planting tamarind, and they are also places that everyone needs to pay special attention to during the planting process.
