At this time, many farmers want to plant pear trees in spring. As we all know, pear trees bloom earlier than many fruit trees. Because the buds of pear trees formed early, they stopped growing in the new shoots, and the bud scales began to differentiate after one month.

After winter dormancy, the average temperature of flower buds reached above 0, and the flower organs in flower buds began to grow slowly, and the temperature further increased, which accelerated the growth of flower buds. Especially in the warm south, the buds bloom earlier. It takes about half a month for flower buds to go from flowering period, flag-revealing period, inflorescence separator, crown-revealing period, flowering period to fire-breathing period. Is it appropriate to plant pear trees at this time? How to manage?

The planting time of pear buds can be divided into autumn and winter seeds and spring seeds. In colder climates, spring sowing is usually carried out before soil germination. Areas that are not cold in winter are suitable for planting in autumn. Planting as soon as possible after defoliation is helpful to root recovery and has a high survival rate. It can grow rapidly after germination in the second year, but it is also suitable for spring planting.

The planting time depends on the growth characteristics of pears and local climate conditions, but the approximate time is divided into1-March and 9-65438+February each year. However, at present, seedlings and container seedlings with mud function can not be planted except in high temperature and dry weather, and can be planted in other seasons. So after the Spring Festival, February can basically end. If it is not arranged in February as soon as possible, it may be later than March.

Because before eating pear trees, there are many preparations to be done, including selecting seedlings, stopping, digging, preparing fertilizer and so on. Especially before planting, when the content of soil organic matter reaches about 1%, the soil should be improved and rebuilt. Even if it can't be improved in an all-round way, we should use normal blood to transform the soil. In hilly areas, the soil layer should be thickened and sticky particles should be added to the beach. In alkaline soil, terraces and drains should be repaired first, and "alkali should be diluted". In plain clay land, we should pay attention to the congestion in Gaza. No matter what land is improved, don't disturb the soil layer. In other words, the top is cooked soil, and the bottom is raw soil. At the same time, organic fertilizer should be applied.

In fact, the preparation before planting is really hard work. All the work needs a lot of time and energy. If you don't do this preparatory work in advance, it will be difficult to finish the formal work before the end of March.

Everyone said, "The teacher's roots are planted in autumn and germinate first in spring. If you plant it earlier in February and March, the result will be one year ahead of schedule. " Early planting will not only affect the parasitic survival rate, but also affect the early fruit of pear trees. We are often told: "Peaches are three apricots, four times five years, and walnuts and persimmons are six to seven years. Jujube can be sold in that year, and ginkgo will be eaten for decades. " In fact, it doesn't have to take five years to plant pear trees and catch up with management measures. As long as effective planting management measures are taken, pear trees will determine the direction and find new branches, so that pear trees can enter the high-yield period as soon as possible. In addition to the correct selection of planting time, we should also carefully deal with planting density, planting measures and post-planting management in order to better achieve the goal of high yield of early fruits. Planting density should be planned according to variety characteristics, climate environment, soil conditions and topography.
