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. Several tropical provinces in our country now basically all have artificial planting bases for macadamia nuts. However, macadamia nuts cannot be planted just anywhere, because macadamia nuts have certain requirements for their growing environment. Below, the editor has brought you the requirements of macadamia nut growth for environmental conditions. Let's take a look!
1. Light
Macadamia nuts have relatively high light requirements. Especially for some fruiting trees, if the tree canopy has poor light penetration, it will not only lead to insufficient light, but also affect the pollination of macadamia trees, causing fruit drop. The fruit-setting rate of the outer branches of macadamia trees about one month after the flowers fall is far higher than that of the inner 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 trees grow, the fruiting branches gradually turn outward, resulting in reduced fruiting inside the canopy. Therefore, we must properly adjust the tree structure to promote light absorption.
2. Temperature
⟦NL>Although macadamia nut is a tropical tree species, the temperature should not be too high. If the temperature exceeds 33 degrees, it will have a certain impact on its yield. In addition, different varieties have different temperature adaptation ranges, 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, different degrees of fruit drop will occur, seriously affecting yield and reducing planting benefits.
3. Moisture
Moisture 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 yield of macadamia nuts. If there is a water shortage, the leaves will show signs of water deficiency after water evaporation. Young leaves will wilt and droop, 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, there should not be too much water either. During the rainy season or if too much water is applied, drainage should be carried out in time to prevent waterlogging damage.
4. Wind
Macadamia nuts have relatively poor wind resistance. Macadamia trees will not only be bent by strong winds, but their flower and fruit quantity and fruit development will also be affected. Especially during the young fruit stage, their 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. Therefore, when choosing planting plots, everyone should try to choose areas with little wind. If the wind volume is large and frequent, then we should establish good windbreak forests around them.
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 plant them, so everyone must pay attention to doing preparation work before planting to avoid losses. That is all for today's introduction.
