Where is the pistachio tree suitable for planting? Introduction to the latest suitable planting regions
The pistachio is a nut with a very good taste. Its tree is a deciduous small tree, native to the Middle East, and was later introduced to some remote mountainous areas of China. So what kind of growing conditions does pistachio growth require, and what kind of regional environment can satisfy its good growth, and where in our country is it currently suitable for planting? Let us take a look together, hoping to give some help to those who need to know.
1. Soil adaptation
Overall, its adaptability to soil is still very strong, and it can generally grow in ordinary soil. But it is best to use deep, loose, dry sandy loam. It adapts to growing in yellow loam and sandy soil. The desert soil of the Xinjiang region seems very suitable for growth. Some barren hills and poor mountainous land can also support its growth. But there is one point: the pistachio is afraid of salinity and alkalinity, and cannot grow in waterlogged environments.
2. Water requirements
The pistachio is relatively drought-tolerant. The annual rainfall should not be too much or too little; about a medium level is best for growth. The key is that summer needs the most water, and it cannot be drought-stricken or lack water, as water directly affects yield at this time. General air humidity has little effect on growth, but soil moisture still has a certain effect. In summer, water can be supplemented for planting.
3. Light and temperature
The pistachio is a sun-loving fruit tree and is not shade-tolerant, so it cannot grow in shaded environments. It needs to satisfy a certain amount of light in order to grow better. This includes fruiting and development, which both need to satisfy a certain amount of light. As for temperature, its adaptability is very strong; it can generally withstand high temperatures, and general suitable temperatures are also very good. Only in some regions of the Soviet Union can pistachios be forced to withstand low temperatures below zero. However, the temperature of the Iran region is the most suitable temperature for pistachio growth.
4. Suitable environment
The northern Shaanxi plateau has a medium annual rainfall level and is a semi-humid region, so it is neither too wet nor too dry. Generally, the light duration is very long, and the temperature is, after all, suitable; the winter low temperature is around minus 5 degrees, which is a completely bearable temperature. The local soil is relatively fertile humus-containing soil, and the growing soil nutrients are very good. Moreover, the local vegetation is sparse, and the pistachio tree has very good growth adaptability, so there are certain planting advantages.
The pistachio has very strong adaptability to soil, temperature, and water, and can be planted in semi-arid regions. At present, it is adapted to the Loess Plateau and Xinjiang, as well as some tropical regions. Tropical regions may relatively speaking have a bit more rainfall, but the impact is not great, and in actual growth, the limitation is not so obvious.
