What are the environmental requirements for macadamia nut growth
Macadamia nuts are a type of nut that many people enjoy eating very much, and the market for them in our country is very large. Basically all of our country's tropical provinces now have artificial macadamia nut planting bases. But not just anywhere can grow macadamia nuts, because macadamia nuts have certain requirements for their growing environment. Below, the editor brings you the requirements for macadamia nut growth regarding environmental conditions, let's take a look together!
1. Light
Macadamia nuts have relatively high requirements for light, especially for trees that are bearing fruit. If the tree's ventilation and light penetration is too poor, it will not only lead to insufficient light, but also affect pollination of the macadamia nut tree, causing fruit drop. The fruit-setting rate of the outer branches of the macadamia nut tree about one month after the flowers fall is far higher than that of the inner canopy branches. Moreover, the fruiting branches of macadamia nuts are mainly perennial branches and spring shoots, and these fruiting branches are concentrated inside the canopy. Then, as the fruit tree grows, the fruiting branches gradually shift outward, causing the amount of fruit set inside the canopy to decrease. Therefore, we must adjust the tree structure well to promote light absorption.
2. Temperature
Although macadamia nuts are a tropical tree species, the temperature should not be too high. If the temperature exceeds 33 degrees, it will have a certain impact on their yield. Also, different varieties have different ranges of temperature adaptability, and different growth stages also have different temperature requirements. For most varieties, during flower bud differentiation, the temperature should be controlled at around 15-21 degrees, with the optimal temperature at 17-19 degrees. During fruit setting, the temperature should be controlled at around 20-30 degrees, otherwise various fruit drop phenomena will occur, seriously affecting yield and reducing planting benefits.
3. Water
Water is also very important for the growth of macadamia nuts. Before flowering, the soil should be kept moist; its water content has a great relationship with the size, quality, and kernel outturn rate of macadamia nuts. If there is a lack of water, after the leaf moisture evaporates, a water deficiency phenomenon will appear. Young leaves will show phenomena such as wilting and drooping, while old leaves lose their luster, and in severe cases, leaves fall. This leads to a decline in photosynthesis in macadamia nuts, and the accumulation of photosynthetic substances will also be seriously insufficient. However, water should not be too much either. During the rainy season or if watering is excessive, drainage should be carried out in time to prevent waterlogging damage.
4. Wind
The wind resistance of macadamia nuts is relatively poor. Macadamia nut trees will not only be blown askew by strong winds, but their flower and fruit quantity and fruit development will also be affected. Especially during the young fruit stage, the flower stalks and fruit stalks are very fragile, and even a slightly stronger wind can break them, causing flower and fruit drop. Wind is also the main cause of macadamia nut fruit drop, so when choosing a planting plot, everyone should try to choose an area with little wind. If the wind volume is large and frequent, then we should establish a good windbreak forest around it.
The above is a brief introduction to the environmental requirements for macadamia nut growth. The growing environment for macadamia nuts is relatively demanding. Therefore, many places cannot grow them, so everyone must pay attention to doing preparatory work well before planting to avoid losses. That is all for today's introduction.
