A kind of pear tree planting method

Abstract

The present invention designs a kind of pear tree planting method, comprises the following steps: special seedling breeding of pear tree, field planting, tree structure cultivation, fruit branch cultivation, tree body nutrient complementation, fertilizer and water, fruit bagging, pest management; Du pear seeds are treated hierarchically, seedlings are raised, transplanted, and T-shaped budding or woody budding is selected. During this period, the fertilizer and water management of seedlings is normally carried out, and field planting is carried out. Then the tree structure is cultivated, and pear seedlings are selected. The part along the row is bent to change the growth direction. The part before the bend of the nursery tree is the trunk, and the horizontal branches at the bend and above are cultivated as the backbone branches of the tree. The extension of the backbone branches of the tree is carried out along the north-south direction. The branches are connected with the adjacent plants by grafting, and then the fruiting branches are cultivated on the backbone branches. The management of fertilizer and water, fruit bagging, and pest control are the same as the conventional management of pear trees.

Description

technical field [0001] The invention relates to the field of pear tree cultivation, in particular to a method for planting pear trees. Background technique [0002] Pear trees are deciduous pear trees. In the production of pear trees, the cultivation of tree structure is very important. An excellent tree structure is the basis for high-quality and high-yield fruit. The tree structure determines fruit output, quality and management labor costs. At present, two tree-shaped cultivation modes of evacuated layered or trellis type cultivation are generally adopted at home and abroad. The evacuated layered tree is tall, and the height of the tree is between 3-5m. Fruit thinning, harvesting is difficult, and labor costs are high, resulting in poor quality of flower buds, poor quality of produced fruits, and inconsistent sizes. At the same time, due to the complex structure of the tree, many levels of branches, many types of fruiting branches, and aging of fruiting branches Seriousl...

Problems solved by technology

At present, two tree-shaped cultivation modes of evacuation layered or trellis type cultivation are generally adopted at home and abroad. The evacuation layered tree body is tall, and the height of the tree is between 3-5m. Fruit thinning, harvesting is difficult, and labor costs are high, resulting in poor quality of flower buds, poor quality and inconsistent sizes of fruit produced, and due to the complex structure of the tree, many levels of branches, many types of fruiting branches, and aging of fruiting branches Seriously, the technical requirements for tree pruning management are high, so it is not easy for fruit farmers to master the technology of pruning management, and the current shortage of rural labor force leads to poor management level of orchards, poor fruit quality, low yield, and poor fruit quality

The current trellis cultivation reduces the height of the tree to a certain extent, which facilitates orchard operations. However, due to the use of grid cultivation, the branches open at a large angle and grow close to the horizontal. This planting mode causes the tree to easily produce elongated branches. Poor stability, serious waste of tree nutrients, need to cut off the long branches every year, increase labor costs

The current grafting methods are single plant grafting with branch and rootstock or branch and tree grafting. The current grafting method is only single plant grafting, and nutrients are also supplied by single plant. waste, so the current existing tree structure cultivation models have their own shortcomings, it is difficult to meet the development needs of the pear tree industry, and the economic benefits of orchards are declining. Therefore, how to test and study labor-saving, light and simple and High-quality tree-shaped cultivation new technology is very urgent to reduce orchard labor, improve fruit quality and orchard economic benefits
