The time starts from December to the end of December. At this time, it is the period when vegetables are changed in spring, because the time for vegetable change in winter is relatively short, and the environmental conditions in winter are compared with other. In the three seasons, it will be a lot worse. If the method of vegetable management and vegetable fertilization is not correct, the growth of vegetables will be more affected. So what do you need to pay attention to during the process of changing vegetables in winter? Let's take a look.
First, the plow bottom of the vegetable soil needs to pay attention to break
Some vegetables may be planted year after year, using a rotary tiller to mechanically turn the ground, forming a plow floor below the 25 cm layer. The soil in the bottom of the plow is poorly breathable, and it is difficult to deepen the roots of the vegetables. Therefore, when changing vegetables, it is best to use agricultural machinery to deepen the soil, to break the bottom of the plow under the vegetable soil, and to improve the permeability of the vegetable soil.
Second, the amount of potassium fertilizer needs attention
Although the presence of potassium has a certain effect on the fruit expansion of vegetables, for vegetable soils with excessive potassium content, it is necessary to control the amount of potassium fertilizer used.
Third, the use of soil conditioning agents need to be cautious
Soil conditioners generally have a good effect on acidified vegetable soils. However, the use of soil conditioners is not too arbitrarily. In some areas where calcareous soils are used, the soil in which the vegetables are grown generally does not undergo acidification, so soil conditioning agents are not required in these soil conditions. It is also recommended to use safer bio-stimulant products, which are better for the improvement of soil aggregate structure and plant nutrition.
Fourth, the vegetable fertilization method should pay attention to
When changing vegetables, pay attention to the method of fertilization. The best method of applying the base fertilizer is to use the vegetables in the whole shed and carry out deep turning.
The above is a brief introduction to the precautions for the winter vegetables in the early spring. In early spring, vegetables have started in many areas, and during this time everyone should pay attention to the management of vegetables and antifreeze.
