Aquilaria sinensis (white woody, earth aloe, daughter incense, gum tree) generally grows below the altitude of 400 meters above sea level. Compared to its distribution area, the aquilaria tree species grows at high temperatures and rains near the Tropic of Cancer. Aquilaria growing distribution climate description:
1, the average annual temperature of 19 to 25 degrees Celsius.
2. In January, the average temperature is 13 degrees Celsius.
3. In July, the average temperature is above 30 degrees Celsius.
4, the annual rainfall of 1600 to 2400 mm.
5, relative humidity 80 to 90?.
Aquilaria sinensis is a land with thick soil and loose humus, loose bricks and red soil or mountain yellow soil. The defoliation compost recovered is a necessary and effective source of fertilizer for the growth period of agarwood.
3. Can Aquilaria trees be planted together with other trees?
Aquilaria semperflorens and other mixed species such as Cyclobalanopsis glauca, Olive, and Yellow twig can be coexisted with Areca and tropical fruit trees. They have deep root and low fat characteristics and do not produce other tree species.
Extruding effect. Because the seedlings of the weak-positive tree species are shaded by his tree, they have grown rapidly since the fourth year, and the average annual growth height can reach 90 cm. It blooms from March to April each year. The flowers are elegant and the fruit matures from August to September. The seed has a short life and should be planted immediately. After germination is unearthed, seedlings can be transplanted and planted at a height of more than 30 cm.
Integrated pest control
1, seedling wilt
Seedling blight occurs when seedlings die out and die. The old seedbeds, poor drainage, and intensive cultivation are susceptible to disease. Control methods: 1 Pre-plantation disinfection seedbed, reasonable close planting; 2 In the early stages of disease removal and use of 70% of diseased plants in a timely manner
The enemy cough 1000 to 1500 times, 50% carbendazim 800 times the soil 2 to 3 times, each interval of 7 to 10 days.
Anthracnose damages the leaves, beginning with brown dots, then expanding to round, oval to irregular spots, and some lesions are rim-like, severely punished when the leaves fall off. Rainy and moist, large dew is conducive to the occurrence of disease. Control methods: In the initial stage of disease, spray 80% of anthrax and 600-700 times of anthrax or 75% of chlorothalonil 400-600 times for 2-3 times, every 7-10 days.
3, leaf roller
Roller leafworms harm each other between the summer and autumn each year. The larvae spit the leaves to roll up the leaves and hide them in the leaves, causing photosynthesis to weaken and affecting normal growth. Control methods:
(1) Manually extinguish and find the leaves in time to cut it off, concentrate deeply, and reduce pests. The worm is the main pest of white wood, and eats leaves when it is severe.
(2) Chemical control can be diluted with 500% solution of 25% insecticidal fleas before insect leaf rolling or egg incubation, or 600-1000 times of 80% dichlorvos EC, sprayed once every 5-7 days, continuously 2 -3 times.
Larvae invade from stems, branches or stem bases, and tree heads, bite xylem, and trunks die when severely damaged. Control methods: manual killing of egg masses and larvae; when boring holes are found, inject 80% dichlorvos 800-1000 times with a syringe, and then seal with yellow mud.
Chafer worms often damage young shoots, tender shoots, and flowers during pumping and flowering. This is also the main pest of white wood. Control methods: manual kill or spray 80% dichlorvos 1000 times control.
