Pear planting density

The planting density of pear trees can be determined according to variety type, tree size, tree planting technology, climatic environment, soil environment and root living environment. In general, for varieties with large crown, many branches and vigorous growth, the planting density can be carried out according to the row spacing of 4-5m and about 30 plants per mu, while the varieties with small crown and few branches can be appropriately denser, according to the row spacing of 3-4m. About 50 plants per mu are planted, while varieties with very small crowns can have a higher density.

First, the type of variety determines the planting density.

The main results are as follows: 1. The planting density of varieties with large crown, more branches and vigorous growth can be a little lower, such as white pear system varieties. Planting 333-500 plants per hectare, the plant spacing of each plant is 4m and the row spacing is 5m.

2. The planting density of the varieties with small crown, few branches and weak growth should be denser, with 500-833 plants per hectare, the plant spacing of each plant is 3m and the row spacing is 4m.

3. Japanese pear varieties such as Fengshui, Yukizu or Nansanji can have a higher planting density because of their very small crown, with 833-1666 trees per hectare, with a plant spacing of 2m and a row spacing of 3m.

Second, the size of pear trees determines the planting density.

Generally, there are about 55 large trees per mu and 75 small trees per mu. If the density of the branches is too high, some should be evacuated, leaving an appropriate number of branches, and the density of the fruiting branches can be adjusted to an appropriate one.

Third, the technology of planting trees determines the density

The quality of planting technology will have a certain impact on the growth and development of fruit trees. whether the planting technology, the way of fertilization is scientific, and the pruning of branches are not in place, all these will affect the growth of fruit trees. therefore, the planting density of pear trees can be determined by mastering planting techniques and cultivation methods.

IV. Planting density is determined by climate and environment

Climatic environment will have a certain impact on the growth and development of fruit trees. In places with poor climatic conditions, the growth of fruit trees is limited and the crown is usually smaller. If you need to plant fruit trees in places where the environment is poor, you can increase the planting density and help the trees resist the adverse climate. If the environment and climate are suitable, the nutrients are sufficient, the fruit trees grow taller and the crown is larger, which can appropriately reduce the density.

5. Soil environment determines planting density.

The planting density of fruit trees can also be determined by the soil environment and fertility. Fruit trees are not easy to grow in low-fertility soil, so the planting distance can be smaller and the density can be higher. On the contrary, it can grow well in fertile and deep soil, and the trees are tall and suitable for low-density planting, with larger plant spacing and row spacing.

6. the root environment of fruit trees determines the planting density.

The root growth of fruit trees is mainly maintained by nutrients in the soil. When the planting density is too high, the growth space of the root system will be affected and reduced, which affects the ability of the root system to absorb water and nutrients and metabolism, and limits the growth and development of the root system. The planting method with large row spacing can be adopted to solve the adverse effects of high-density planting, and the spatial and nutritional problems of root growth can be considered from the perspective of high-density planting.
