How to water transplanted trees in autumn and winter?

Trees transplanted in autumn and winter need to be watered with cha pipes, but not too often. In winter, the metabolism of plants declines. If it is a deciduous plant, it is basically dormant. Evergreen plants metabolize faster only during the day, so it is not necessary to water them too often. If you water them often, it's easy to get water in the roots, so plants will die.

Secondly, it has something to do with your planting environment. If you are in the ground at ordinary times and don't need watering in winter, natural precipitation can basically be maintained. If you are in a flowerpot, you should water it when the sun is shining during the day. The reason is that watering at night, if the temperature is too low, the space in the flowerpot is small, and the water in the soil is easy to freeze, which will directly hurt the roots of plants and cause freezing damage.

Winter is one of the four seasons, between autumn and spring. Astronomically speaking, it was from February to March in 65438. China used to refer to the three months from beginning of winter to beginning of spring, and also referred to the "October, November (winter) and December (wax) months" of the lunar calendar. The time in the northern and southern hemispheres is different. According to the meteorological significance, in the temperate and cold regions of the southern hemisphere, winter is in June, July and August (or May 2 1 to August 22 according to the constellation standard), in the temperate and cold regions of the northern hemisphere, winter is in the solar terms of 12, 1 and February (or according to the constellation standard/kloc-0) Westerners generally call winter the solstice and spring the winter. From the climatological point of view, it is winter when the average temperature is lower than 10℃ for five consecutive days.

Transplanting, also known as transplanting, refers to the operation of transplanting the seedlings in the seedbed into the field.

The transplanting period depends on crop species, suitable seedling age and stubble. Generally, rice is transplanted with leaf age index of 40%-50%, cotton is transplanted with 2-4 leaves, and corn is most suitable for 25-35 days after emergence.

Transplanting can be done with or without soil. Transplanting with soil can shorten the slow seedling stage, live early and develop early. Water and moisten before transplanting to avoid root injury or less root injury. When transplanting, determine the row spacing according to the planned specifications, and determine the transplanting depth according to the crop species and seedling size. Generally, the depth is about 3cm, which requires the same depth. It is best to transplant large and small seedlings in different levels, and fertilize and water them in time after planting to promote survival and seedling growth.

Generally, newly planted trees must be watered thoroughly for the first time to meet the water demand of trees. In May and June, the temperature rises day by day, the trees grow vigorously, and the transpiration of trees is obvious, so it is necessary to increase the frequency and quantity of watering. In July and August, the weather is hotter and drier, and at the same time, trees have reached a period of vigorous growth and development. At this time, the irrigation amount should reach full irrigation, and the surface soil should not be wet when the bottom soil is still dry.

The correct watering method is to distribute water evenly, reduce soil erosion, maintain a good soil structure, give full play to water use efficiency and pay attention to saving water resources.
