Second, transplanting 1, Ouping hybrid hazelnut planting 1 selection Ouping hybrid hazelnut tree is a tall shrub - small tree, 3 years old began to result, 6 years old is the early fruit period, 7-10 years old fruit for the early fruit, more than 10 years for the full fruit period, continuous high yield, life expectancy More than 50 years. Fushun can be planted in the territory. Ouping hybrid hazelnuts have strong adaptability and can be cultivated in all types of soils. However, soils with deep, fertile, PH value of 5.5-8, and well-drained sandy loam are most suitable. Auping hybrid hazelnuts like hi light can be cultivated on any slope direction below a slope of 15 degrees, but it is best to use deep slopes and well-drained flat lands in the lower and middle parts of the sunny slopes. 2 selection seedlings Nearly 100 strains of new varieties of Ouping hybrid hazelnuts have different performances in different regions. In particular, special attention should be paid to its cold resistance. The strains that have been successfully grown in the region or cultivated in similar areas should be selected. Ouping hybrid hazelnut should be used to plant seedlings. Hazelnuts are all cross-pollination plants, planting asexual propagation of seedlings to configure the pollination tree. The ratio of the main cultivars to the pollination cultivars is 6-8:1; several fine cultivars can also be mixed and pollinated. 3 planting methods In the autumn of the previous year, the planting pits with depths of 60 to 70 centimeters each were dug, mixed with organic fertilizers, weeds and dead leaves, and then filled into the topsoil. Planting time should be in the middle of April. Before planting, cut the roots of the seedlings and cut the roots that are too long. Keep 12-15 cm. Planting seedlings should not be too deep, seedlings can not appear under the pit phenomenon. Immediately irrigated after planting. According to the comprehensive conditions of planting plots, the density of planted hazel seed should also be different. The commonly used plant spacing is 2 m × 2 m, with 156 per mu; 2 m × 3 m, 111 per acre; 2 m × 4 m, 83 per acre; 3 m × 3 m, 74 per acre; 2.5 m × 4 m, 66 per mu. Practice has proved that in Fushun area, 2m × 3m, that is, 111 plants per mu is the best; 2m × 2m, ie, 156 plants per acre are suitable for the first 10 years and are suitable for seedling propagation; 10 years later can be changed to 2 m × 4 meters. 4 Field Management Ouping hybrid hazelnut field management is relatively simple and easy, including pruning, fertilizing, weeding, irrigation and so on. A: Trim. Ouping hybrid hazelnuts are single dried. The natural tree height can reach 5-8 meters, but the hazel after pruning should not exceed 4 meters in general. The single-dry trimmer program is: In the first year, one-year-old seedlings are planted and planted immediately after planting in the spring. The stem height should be 40-70 cm, and the trunk should be vertically upward. For planting two-year-old seedlings, the branches below 40 cm should be cut off; annual branches should be short and heavy. In the second year, 3 to 5 main branches with different orientations were left in the main trunk. Each main branch was light and short cut, and about 1/3 of the branch length was cut off. In the third year, for each main branch left on the trunk, 2-3 collateral branches were selected and light and short cuts were taken. The original main branch was continuously cultured to extend the branches, and the branches were extended to light and short cuts, and they grew obliquely upwards. The internal branches were not trimmed. . In the fourth year, continue to light and short cut the main and lateral branch extensions and continue to expand the canopy. Three to five main branches were formed on the main stem, the lateral branches grew on the main branches, the secondary branches on the lateral branches and the resulting mother plants grew, and a naturally happy crown was formed on the short upper trunk. Pruning time: The first is during the dormant period. Ie winter pruning. Fushun Yichun cut. The second is pruning in the growing season. That is, pruning in summer aims to regulate the reasonable distribution of nutrients. B: Fertilization The use of fertilizer and water should be based on the benefits of increasing the amount of solid fruit. Fertilization is divided into base fertilizer and top dressing. Schiff base should be applied in the autumn after the nuts are harvested and before the soil is frozen (from September to October). The first top dressing should be from late May to early June, and the second time should be from early July to mid-July. C: weeding soil 4-6 weeds can be removed each year, preferably after rain or irrigation. There should be no weeds in Ouping hybrid hazel. However, in the past few years, low- and short-term crops can be used. D: Irrigation The newly planted seedlings must be timely watered. In general, the irrigation period is 2-3 times, which can be combined with topdressing at the same time. The first time before germination; the second time from late May to early June is the expansion of young fruit and the vigorous growth of new crops. This is the key to guarantee the production of the year; the third irrigation can be conducted in the late June when there is little rain. . In the rainy season in July, pay attention to drainage. 2. Planting of flat hazelnuts Ping hazelnut planting can be divided into single row planting, strip planting, crypt planting and other cultivation methods. Due to different cultivation methods, the density is also different (see table below). Flat hazelnut planting density table Planting methods Plant spacing (m) Line spacing (m) Number of acres (clusters) Suitable block Single row planting 1.5-2 2-2.5 133-222 Mechanized operation garden Ribbon planting 0.8-1 1-1.2 333-476 More formal and upright slope garden Cave planting 1-2.5 1-2.5 Hills, mountains, valleys and sporadic planting 1 Single planting: It is planted on a gentle slope, terraced field or horizontal ditch in a single row at a certain plant spacing. Its row spacing can be flexibly controlled by location. 2 Strip planting: that is, two rows or several behaviors, the distance between the belt and the belt is slightly larger, and the spacing between the belts is too small to form a strip. The number of planted plants per unit area is more, which can increase the early yield. Band spacing is generally 2.5-2.8 meters is appropriate. 3 hole planting: that is, in the hills and mountains where the terrain changes greatly, according to the topography features, scattered and scattered planting, plant spacing can be flexibly mastered. 4 Planting methods and management Planting seedlings, strong seedlings per hole, weak seedlings 2-3 per hole, roots and ground level, fill in step solid; planting seedlings and root seedlings, should pay attention to the direction of the old rhizome, the original upward The buds are still upward. When planting, put the root into the hole, and the depth of the root can be covered with 10 cm thick soil. 3-5 years for a renewal. Other aspects were carried out according to the Ouping hybrid hazel planting method. BTE Hearing Aid BTE Hearing Aid Shenzhen Sunshine Technology Co.,Ltd , https://www.yatwinsz.com
