The geographical distribution of the fat sea
3 geographical distribution Distributed in Vietnam, India, Malaysia and other places. Site preparation: Choose sandy loam, yellow loam soil and brick red loam that are well-drained and sheltered from flat ground or slopes. Cut down the shrubs and weeds first, and then plant after excavating the roots. 1 Seed breeding. The mature seeds with blackish brown skin and obvious wrinkles on the surface were sown on a clean sand bed and on demand. The distance between seeds was about 3 cm. After sowing, cover with sand, then cover the surface with straw, soaked with water, and keep the surface wet. After budding, it can be transplanted into the nutrition bag nursery for nutritious soil for seedlings, as soil and decomposed cow dung, in a ratio of 3:1, or in a 2:1 mixture with compost. After sowing, shading and moisturizing are needed. After new roots are established, the shade can be gradually reduced. The seedling height is 30 to 50. Big sea fruit Big sea fruit (4 photos) It can be planted in Daejeon in centimeters. 2 air pressure strip breeding. Select the corked branches, circumcision at a distance of 20 to 30 centimeters from the top, the width of the girdling is about 3 cm, and the depth is up to the xylem, and scrape off to form a layer to prevent the healing. After girdling for about 1 to 2 days, after the wound is slightly dry, wrap it in wet mud with wet cocope or straw and wrap it around the wound with a plastic wrap. After about 2 months, grow a new root. If corkification has already begun, the branches can be cut and planted in the sand, or directly planted in the field, and the survival rate can reach more than 80%. Colonization: Both spring and autumn can be planted, and the survival rate is high when planting on cloudy or rainy days. Row spacing is 4 meters by 4 meters. 41 plants per acre are planted with 50 cm of planting holes of length, width and depth. Each hole is cooked with mature cows or 15-20 kg of compost. After mixing with the top soil, the seedlings will be planted. Remove the nutrition bag and put it in the hole. Cover the soil about 20 to 30 cm thick. Drench it with water and shade. After the seedlings have survived, the shade can be gradually removed. 1 fertilization. When one year after planting, fertilize one time per quarter, apply 1-2 kg of urea per mu, decompose beef cattle compost or 800-1000 kg of compost, use acupuncture and apply soil after application. 2 Topped. One year after the planting of the fat sea, the plant height has reached about 1 meter, and the top can be dwarfed. The method is to use a branch cutter or bud grafter to cut at a distance of about 2 cm from the growing point. After about 14 to 35 days, a new branch is drawn and 2 to 3 branches are left until it is continuously drilled 2 or 3 times. After the second picking, the top picks up 3 times in succession, and the dwarfing is achieved. Green scale weevil. Adults damage leaves and tender stems, causing irregular nicks and broken tender stems. Control methods: 1 Manually kill and use the adult's dead-dead habits, tap the leaves with a stick to make the insects fall to the ground and concentrate to kill; 2 spray with 50% phoxim 1000 times.
