1.3 Variety selection and pollination tree configuration
1.3.1 Variety selection: Choose the varieties with strong cold resistance and safe wintering, mainly Pingou 110 (82-11 large fruit); Dawei (84-254 fruit); Liaojing 3 (84-226 large fruit) ); Jade pendant (84-310 small fruit); Pingou 210 (81-21 small fruit); Pingou 28 (85-28 small fruit), and other varieties that have been stably introduced for many years.
1.3.2 Pollination tree configuration: When planting the garden, 3-4 main varieties should be planted, and each variety should be planted 3-4 rows. The plants can be pollinated with each other, or the main varieties can be 4-5 rows. Line, meet the pollination, the effective distance of pollination is less than 18m.
1.4 Planting methods
1.4.1 Planting density: The land is fertile, and the planting distance of the flat land is larger, and the planting distance of the mountain with larger slope and thin soil can be smaller. The fruit is mainly grown at 3 × 3 m (1100 plants/ha), 4 × 2 m (1250 plants/ha) or 4 × 2.5 m (1000 plants/ha).
1.4.2 Planting method: The north-south direction of the flat planting is good, which is beneficial to the uniformity of the trees and the mountain along the contour line. Planting methods include rectangles, squares, and triangles.
1.4.3 Site preparation: Before planting, it is necessary to clean up the rattan shrubs, weeds, stones and other debris, and then deep-turn the whole garden, and the depth of deep turning is more than 30cm.
1.4.4 Drilling at a fixed point: the site is fixed, and the pit is excavated according to the point. The excavation is best in the autumn of the previous year. It should be centered on the planting point, with a diameter of 70-80 cm and a depth of 60-70 cm.
1.5 seedling preparation
Choose high-quality seedlings with developed roots, 8-10 pieces of woody roots, root lengths of 20 cm or more, seedlings with more roots, full stems, and seedling heights above 80 cm. After the selection, the roots of the seedlings are trimmed and the length is 10-12 cm.
1.6 Planting technology
1.6.1 Planting time: From April 20th to May 10th, the soil is thawed more than 25cm, and the seedlings are not suitable before germination.
1.6.2 Planting method: The soil is required to be wet before planting, and water is poured immediately after planting. When planting, it should be suitable for depth and depth. The root neck and the ground level should be 3-5 cm below the ground, that is, the depth of the buried soil above the root is 6-10 cm.
2. Management in the same year after planting
2.1 Drain after planting: Set the dry height to 50cm. After drying, apply lead oil on the cut to prevent water loss. The dry height of the single dry shape is 40-60 cm, and the dry height of the dry cluster is about 30 cm.
2.2 Watering irrigation: The cultivation garden combines fertilization and watering three times a year, the first time before and after germination, the second time in May-June, the third time after defoliation and before the soil is frozen.
2.3 cultivating and weeding: pay attention to deep-turning, expanding, weeding and loosening in the growing season, usually every other year. Minimize root damage when deep turning and expanding. The weeding of loose soil is generally carried out about 5 times a year.
2.4 Fertilization and topdressing: In the autumn after picking the fruit and before the freezing, combined with deep-turning into the base fertilizer, mainly organic fertilizer; topdressing soil fertilization and root topdressing two kinds, soil fertilization can be applied by annular ditch, radial ditch, ditch Fertilization and acupoint fertilization, mainly compound fertilizer, the fertilization depth is 20-30 cm.
2.5 Winter management: fill the frozen water once before winter, remove the mulch, and then protect the soil from cold.
2.6 Inter-line intercropping: In the first three years, intercropping crops or medicinal materials may be planted, and the intercropping crop is not less than 80 cm from the eucalyptus.
3. Plastic trimming
The local cultivation is mainly single-dry, with a dry height of 50-70cm, and 3-4 uniformly distributed main branches are selected on the trunk, and the side branches and the resulting mother branches are placed on the side branches. Winter pruning is carried out in the dormant period of eucalyptus, and pruning is carried out in March. The extension branches of the main branches of the tree during the fruiting period should be lightly cut, and cut off by 1/3 or 1/2 of the length to promote the occurrence of new branches. In order to increase the amount of flower buds and increase the yield, the middle branches and short branches are not pruned, and only the extension branches of the main side branches are lightly shortened.
4. Pest control
4.1 Disease prevention
Powdery mildew: harms leaves, infects shoots, shoots and preserves;
Control methods: improve the ventilation and light transmission conditions of eucalyptus, and enhance the disease resistance of the tree; spray the triazolone 800 times solution to the tree from May to June, every 7-10 days.
