Description
Technical Field
The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a method for orchard establishment of early-fruiting high-yield rootstocks of apple trees.
Background
For a long time, finished seedlings are mostly adopted for apple orchard establishment, the survival rate of nursery stocks for orchard establishment is low, the investment cost is high, and the variety of the nursery stocks cannot be guaranteed, so that the problems of mixed varieties, low yield and poor benefit exist in most apple orchard. Therefore, the high-standard apple orchard can be built by utilizing the spring planting and autumn grafting of the apple seedlings in the current year, selecting the variety of the medium-short branch type apple, and carrying out comprehensive cultivation technologies of timely pinching and bud carving, mulching film covering and the like. Not only ensures the purity of the young tree variety, but also reduces the investment of nursery stock for garden building, and is suitable for modern dwarf close planting cultivation. Because the grafting part of the traditional nursery stock is generally 10cm above the seedling stock, the tree form is free spindle shape, the row spacing of the tree is 3 multiplied by 4m or 4 multiplied by 5m, the full bud is selected at about 100cm after planting, the tree body randomly branches after stem fixing, the branches below 80cm of the trunk are useless branches, the branches need to be pruned in successive years, the damage to the tree body is more, the main branch group culture above 80cm is influenced, the crown is tall and big, the orchard is closed, the pruning quantity is large, the forming is slow, the flower formation is slow, the fruiting is late, the photosynthetic efficiency is low, and the fruit yield is low.
Disclosure of Invention
The invention aims to: the technical means of planting wild apples or crabapple seedlings in the spring of the same year, grafting in the autumn, pruning in the next year and shaping and trimming in the later period are adopted, so that the problems of large trimming amount, slow forming, late flowering, late fruiting, high crown, low photosynthetic efficiency, low fruit yield and the like of the traditional apple seedling orchard building are solved, and the technical effects of high seedling survival rate, small trimming amount, quick forming, early bearing, tree vigor, dwarfing tree body, good high yield and high quality fruit rate are realized.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
a method for building a garden on an apple tree early-bearing high-yield rootstock comprises the following steps:
1) planting and building a garden: planting Xinjiang wild apple seedlings in spring, and specifically building a garden according to the density of 1.5-2m multiplied by 4 m;
2) high grafting in autumn: in autumn of the year after planting, selecting good apple variety scions to carry out bud grafting with wood at a position 60-70cm away from the ground of the seedlings of the wild apple trees in Xinjiang;
3) spring pruning: pruning 0.5cm above the grafted buds after planting before sprouting in spring of the second year to ensure that the grafted buds sprout and shoot, uniformly erasing the other lower germinated branches, and drawing partial branches in summer to facilitate shaping and flower formation because the buds grow vigorously and grow 7-8 or more branches with wide angles due to good healing;
4) drawing a branch thin tube: in the third year after planting, pulling branches to promote flower growth, pulling branches completely at the bottom of 6 months to promote flower formation, after harvesting apples in autumn, trimming in winter, and trimming into a high spindle shape or a slender spindle shape according to the requirements of tree shapes;
5) ensuring high yield: and ensuring high yield in the fourth year, carrying out branch pulling and pruning in successive years, culturing 1-2 year-old robust bearing branch groups, maintaining tree vigor, and subsequently carrying out reinforcement management.
Further, when the plantation in the step 1) is built, the crabapple seedlings can be selected to replace the wild apple seedlings in Xinjiang to be planted and built.
Further, the seedlings of the Xinjiang wild apples and the seedlings of the crabapples are 1 year old.
Further, when the autumn high grafting is carried out in the step 2), selecting medium and short branch type good apple varieties, such as 'maturity No. 1', 'Yanfu No. 6', 'Ruixue' and the like, and carrying out ligneous bud grafting at the position 60-70cm away from the ground of the Xinjiang wild apple or the crabapple tree seedling.
Compared with the prior art, the invention has the beneficial effects that:
1) the method selects 1-year-old Xinjiang wild apple or Chinese flowering crabapple seedlings to be planted to build the garden, the wild tree species have the excellent characteristics of low cost, freezing resistance, drought resistance, salt and alkali resistance and rot resistance, the adaptability to the garden is strong during planting, the survival rate can reach more than 95 percent, and particularly the planting survival rate of the Xinjiang wild apple seedlings can reach more than 98 percent; meanwhile, the Xinjiang wild apples or Chinese flowering crabapples are used as the stocks to build the garden, and the garden has the advantages of regular garden appearance, dwarfed tree body, quick forming and early fruiting; in addition, the invention selects the good varieties of medium-short branch type such as 'maturity number 1', 'Yanfu number 6', 'Ruxue', etc., which have the characteristics of easy flower formation, easy control of tree vigor and strong dwarfing, and are suitable for modern dwarfing close planting cultivation of northwest loess plateau;
2) the high-standard apple orchard is built by adopting the technical means of spring planting in the current year, high grafting in autumn, pruning in spring of the next year, shaping and trimming in later period, and only grafted buds germinate and shoot and the rest lower germinating branches are completely removed, so that only the grafted buds germinate and shoot to form a tree body, the growth vigor and the shape of the tree body can be effectively controlled, and the later period trimming and shaping are facilitated; the lower parts of the grafting buds have no branches, so that the successive thinning and trimming amount is reduced, the damage of the thinning and trimming to main branch groups of the tree body is reduced, the trimming amount is reduced, and the photosynthetic efficiency of the tree body is improved; meanwhile, the grafted buds can be healed in about 15 days, the buds are well healed and grow vigorously, 7-8 secondary branches are extracted, and the branches are opened at angles, so that the buds can be shaped into flowers conveniently; in addition, the bud grafting position is 60-70cm away from the rootstock, the height not only can ensure the space distance required by the extension of the branch during the later period pruning, but also can effectively control the growth of the top end of the tree body, and the tissue grafting success rate at the position is up to more than 92%;
3) the method for building the orchard by the rootstocks has the advantages of low cost, tidy garden appearance, small later trimming amount, quick forming, strong tree vigor, good high yield, high quality fruit rate and the like, fruit trees in the orchard have good freezing resistance, drought resistance and rot resistance, more importantly, the traditional method for building the orchard by the vigorous apples generally takes 6-7 years to carry out fruit bearing, but the method for building the orchard starts to carry out fruit bearing from 3 rd year, and compared with the traditional method for building the orchard to carry out fruit bearing earlier for 2-3 years, the method for building the orchard by the rootstocks is suitable for being popularized and cultivated in regions such as northwest loess plateau drought, northeast cold regions, southwest cold regions, Bohai gulf and the like.
