A detailed guide to the latest key points for growing pistachio trees

The pistachios we usually see are basically processed products, and many people have never seen pistachios growing on trees. In fact, pistachios are initially wrapped in a layer of skin, but what we eat is only the kernel. The economic value and sales volume of pistachios on the market are both very good, but many pistachios are not quite ideal in quality. So today Qinnong.com will tell you a few issues that need attention during planting, so that you can ensure your pistachios have high yield and good quality. Let's take a look below.

1. Soil

Just from the name pistachio, it sounds happy no matter when, so it seems it can grow anywhere. However, if you want to grow high-quality and high-yield pistachios, then the quality of soil selection is the most basic condition for pistachio growth. We generally choose soil with good permeability or sandy soil. Calcareous soil and yellow soil are both very good choices. Next, the soil pH is best moderate. Of course, it can also be slightly acidic, but it must never be alkaline, otherwise it will directly affect its growth.

2. Water

Pistachio growth also has certain requirements for water, and it cannot grow in soil with standing water. Therefore, the planting site is best to have a certain slope and no pits or hollows. Next, during its growing period there must also be water. If there is less rainfall, although it will still bear fruit, the quality will simply be too poor to look at. Especially if there is a lack of water in summer, it is very likely that you will get nothing and all your efforts will be in vain. Therefore, the humidity of the planting site should be maintained at at least about 40% to 50%. Next, the average annual rainfall should reach about 300 mm. Only in this way can the normal growth of pistachio trees be maintained.

3. Light

The pistachio tree is a plant that greatly loves light, so its requirements for light are relatively strict. The growth of pistachio trees needs sufficient photosynthesis, so that they can bear fruit. According to relevant statistics, in one year a pistachio tree needs at least 3,000 hours of light. This also means that it basically needs to be under light for about 8 hours a day. Next, the temperature for pistachio tree growth is best kept at about 28 to 30 degrees. However, during the fruiting period, the greater the temperature difference between day and night, the more fruit it bears, so you can increase the temperature during the day and lower it at night.

4. Fertilization

⟦NL>Fertilization management for pistachio trees is carried out in stages. During the seedling stage, only one fertilization is needed. Adult fruit trees need at least three fertilizations a year, according to the growth period. The first is when they sprout in spring, the second is when they bloom, and the third is after fruiting. After the fruit trees have gone through four or five years, we need to add one more fertilization on this basis to prevent the saplings from aging and reduce yield. Therefore, after each harvest, one more fertilization is also needed. Of course, for pistachio trees, fertilization is best based mainly on organic fertilizer.

5. Pruning

Because pistachio trees have relatively strict requirements for light, pruning branches and leaves is also very necessary. Reasonable pruning can enhance the light transmittance in the orchard, so that the fruiting rate of pistachio trees can be ensured. We generally prune away weaker branches and leaves, dead branches, old branches, diseased branches, and branches and leaves in places where growth is too dense.

6. Pollination

The pistachio tree is a monoecious plant, which means it can perform self-pollination. Although the fruit-setting rate of self-pollination is high, the fruit is not firm, and fruit drop is very serious. Therefore, to a certain extent, we need to carry out artificial supplementary pollination, which can increase the success rate of fruiting and thereby increase the final yield of pistachios.
