Cashew growing environment

If the fruit is a special fruit, its shape is like that of a human kidney, so it is named cashew. Cashew has high nutritional value and is a famous dried fruit. The fruit can also be used as medicine. It is mainly planted in Yunnan, Guangdong, Fujian, Taiwan and other places. From these main planting sites, we can roughly see that cashew nuts are suitable for growing in a relatively hot climate. What is the specific growth environment and what are the necessary factors? now let's take a look.

I. Climate

Mainly grow in the tropics, but do not like too humid environment, prefer sunny, warm, freeze-free environment. Poor cold resistance, easy to die from cold. Areas like Hainan are very suitable for cashew growth, so the climate is suitable for cashew growth.

2. Soil

Clay and calcareous soils do not grow well, and soils with low content of organic matter, such as red soil, do not grow well. In loose, breathable, fertile, deep soil growth is good, must be loose, prevent stagnant water, good air permeability, root growth is also very good. More resistant to drought, so do not plant in low-lying land, resistant to barren, but still provide fertile soil.

Third, temperature

Growth requires a monthly average temperature of 23 to 30 degrees, below 23 degrees is slow, below 20 degrees affects growth, below 17 degrees is easy to freeze, and below 15 degrees is dangerous. Because cashew nuts like temperature, must grow in a warm environment, below 23 degrees can not blossom and bear fruit, flowering and fruiting period suddenly encounter low temperature, will fall flowers, poor fertilization, drop fruit or form abnormal fruit.

4. Moisture

The root system is strong and drought-resistant, but try to keep it moist, not too dry, the growth will be better, do not water during flowering, can be properly watered before flowering, fruiting period, the peak growth period is generally in the rainy season, timely drainage, florescence can not encounter rain, the groundwater level is too high is not suitable for planting. Because the root system is strong, it is mainly watered in the fruiting period, not too much, about once a month.

5. Lighting

Xiguang, must be sufficient sunlight to grow, not shade-tolerant, can not grow in a hidden environment, especially requires annual light to be more than 1800 hours, but it does not mean that lower than this light will have a serious impact, but poor growth conditions, such as flowering must be enough light to flower bud differentiation, fruit expansion also needs enough light.

Cashew growing environment is a tropical environment, to warm, sufficient light, soil requirements are not strict, strong adaptability, strong root system, need water, but can not be flooded, can not be frozen. Therefore, planting and production should pay attention to these problems.
