Planting conditions of durian honey

Durian honey is a popular tropical fruit, which is a well-known specialty in Malaysia, Thailand, Vietnam and other places. It is cultivated in Hainan, Fujian and Guangxi in China. So what are the planting conditions for durian honey?

I. planting conditions

1. Temperature: the average annual temperature suitable for durian honey growth is only 27 degrees to 31 degrees, and can withstand a short period of low temperature. It can be planted in Taiwan, Hainan and other places in China. There is a very significant correlation between temperature and the growth of durian honey, indicating that air temperature is an important factor affecting the growth of durian honey. Durian honey grows slowly when the average temperature is below 20 ℃, grows faster when the temperature is 21-28 ℃, and reaches the maximum when the temperature is 29-30 ℃. The plant grows fastest in the high temperature season when the monthly average temperature is 29-30 ℃.

two。 Site selection: garden soil and climate should be suitable for durian honey growth. The slope is below 25 °, the soil requires good permeability, the content of organic matter is more than 1%, and the pH value is 5.3-6.8. However, the water and fertilizer conservation performance of sandy soil is poor, which is not conducive to the growth of durian honey, and the production cost is high, so it is generally not suitable to plant durian honey.

3. Shelterbelt: shelterbelt should be built around the lotus honey orchard. The fast-growing wind-resistant tree species such as Eucalyptus urophylla 12, Casuarina equisetifolia, Hainan May Tea, Qiongya Begonia, maternal and Chongyang wood should be selected for the shelterbelt, which do not have the same main diseases and insect pests as durian honey.

II. Planting techniques

1. Planting time: after the young shoots of the seedlings are mature, the orchards with poor irrigation conditions will be planted in rainy and cloudy days, mainly in spring and autumn. In Hainan, China, orchards with good irrigation conditions can be planted all the year round.

two。 Planting method: the length × width × depth of the planting hole is 80 cm × 80 cm × 60 cm. When digging holes, separate the topsoil from the subsoil, and backfill with straw, human and animal manure, green manure and other organic manure and calcium magnesium phosphate fertilizer or superphosphate. 30-40 kg of organic fertilizer, 1-2 kg of phosphate fertilizer and 0.5-1 kg of lime are applied to each hole. Green manure, straw and lime are placed in the lower layer of the planting hole, human and animal manure, calcium magnesium phosphate fertilizer or calcium superphosphate are placed in the middle layer, and topsoil is placed in the upper layer of the planting hole. The preparation of planting hole was completed one month before planting. When planting, a tree plate with a diameter of about 1 meter is made around the seedlings, which should be drenched with fixed root water, cover with moisturizing and inhibit the growth of weeds.

3. Fertilization: temperature is significantly correlated with the growth of durian honey, indicating that air temperature is an important factor affecting the growth of durian honey. Among them, durian honey grows slowly when the monthly average temperature is below 20 ℃, grows faster when the temperature is 21-28 ℃, and reaches the maximum when the temperature is 29-30 ℃. The plant growth is the fastest and the growth is the largest in the high temperature season when the monthly average temperature is 29-30 ℃. The amount of fertilizer applied in this period should account for more than 50% of the annual fertilizer application. One year after young tree planting, 30-50 kg of mature human and animal manure and 300-500 g of compound fertilizer were applied to each plant. The fruit tree should appropriately increase the amount of fertilizer each year according to the amount of fruit.

4. Moisture: appropriate amount of irrigation is needed when drought occurs in the period of new shoot emergence, flowering, flowering and fruit development of durian honey, and the amount of irrigation should be wet through the main distribution layer of the root system. During the flowering period of durian honey, water should be controlled to keep durian honey in a moderate drought condition, which is beneficial to flower bud differentiation. The accumulation of water for a long time will affect the growth of durian honey. Therefore, the rainy season or orchard stagnant water, should be timely drainage.

The cultivation conditions of durian honey are relatively high, there are only a small amount of cultivation in China, and the price is relatively high in the interior. If the local temperature is too low, you need to be careful to grow durian honey.
