Environmental requirements for the growth of Hawaiian fruits

Hawaiian fruit is a kind of nut that many people like to eat very much, and it is a very big market in our country. At present, several tropical provinces in China basically have artificial planting bases for Hawaiian fruits. But Hawaiian fruit can not be grown everywhere, because Hawaiian fruit has certain requirements on the growing environment. The following editor brings you the environmental conditions for the growth of Hawaiian fruit. Let's have a look!

1. Lighting

Hawaiian fruit requires high light, especially some fruit trees, if the permeability of fruit trees is too poor, it will not only lead to lack of light, but also affect the pollination of Hawaiian fruit trees, resulting in fruit drop. The fruit setting rate of the outer branches of Hawaiian fruit trees is much higher than that of the inner branches about a month after the flowers fall. And the fruiting branches of Hawaiian fruit are mainly perennial branches and spring shoots, and these fruiting branches are concentrated in the crown, and then with the growth of fruit trees, the fruiting branches will gradually turn to the outside, resulting in a decrease in the amount of fruit in the canopy. Therefore, we must adjust the structure of fruit trees to promote light absorption.

2. Temperature

Although Hawaiian fruit is a tropical tree species, the temperature should not be too high. If the temperature exceeds 33 degrees, it will affect its yield to a certain extent. And the temperature adaptation range of different varieties is also different, and different growth stages also have different temperature requirements. During flower bud differentiation, the temperature of most varieties should be controlled at about 15-21 degrees, and the best temperature is 17-19 degrees. When setting fruit, the temperature should be controlled about 20-30 degrees, otherwise it will produce different fruit drop phenomenon, seriously affect the yield and reduce the planting benefit.

3. Moisture

Moisture is also very important for the growth of Hawaiian fruit. It is necessary to keep the soil moist before flowering, and its water content is closely related to the size, quality and kernel yield of Hawaiian fruit. If there is a lack of water, the phenomenon of water shortage occurs after the evaporation of leaf water. While the young leaves will appear withered, drooping and other phenomena, the old leaves lose their light, and when they are serious, the leaves fall. As a result, the photosynthesis of Hawaiian fruit decreases and the accumulation of photosynthetic matter is seriously insufficient. But the moisture should not be too much, encounter the rainy season or too much watering, but also timely drainage to prevent waterlogging.

4. Wind power

The wind resistance of Hawaiian fruit is relatively poor. Hawaiian fruit trees will not only be swayed by strong winds, but also affect the flower and fruit quantity and fruit development of Hawaiian fruit. Especially in the young fruit period, its flower stalk and fruit stalk are very fragile, and a little stronger wind can blow it off, resulting in falling flowers and fruits. Wind is also the main cause of fruit drop in Hawaii, so people should try to choose less windy areas when choosing planting plots. If there is a lot of wind, then we should build a windbreak around us.

The above is a brief introduction to the requirements of the environmental conditions for the growth of Hawaiian fruit. The growth environment of Hawaiian fruit is relatively harsh. Therefore, it is impossible to grow in many places, so we must pay attention to make preparations before planting to avoid losses. That's all for today's introduction.
