The first frost is coming. If you want to come next spring, leeks will grow vigorously, so make these three stops.

With the approach of the first frost solar term, the outside temperature is gradually decreasing. Dewdrops on the ground in the morning and evening tell the story of a cold night. At this time, the farmers are busy. The fields are full of laughter, and the vegetables in the small vegetable garden are lush. Careful people will find that the Chinese cabbage and peppers in the garden are normally picked and eaten, but the lush leeks are left unattended and farmers let them grow naturally.

Leek is a perennial root vegetable with strong adaptability, cold resistance and heat resistance. It is cultivated in all parts of China. According to the edible part, it can be divided into four varieties: root leek, leaf leek, flower leek and leaf leek Because of the high yield and simple management of leek, it is very common to grow leek, also called sunny grass. It tastes very delicious and has a unique fragrance. It has become a crop planted in some areas, especially in early spring.

First, stop cutting.

Chinese chives like to be cool, and the optimum growth temperature is 15℃ to 25℃. When the temperature is cold in winter, the aboveground part will die, and the underground part will go into a dormant state. In spring, the topsoil will thaw, start to sprout and grow again. Before the first frost, the growth of leek gradually slowed down and the stress resistance began to deteriorate. At this time, if we continue to harvest leeks, leeks will continue to produce new leeks due to the top advantage, which will cost.

Second, stop fertilization.

The first frost of leek entered the solar term, and the cold outside temperature led to the slow growth of leaves, which was due to the weak absorption capacity of roots. This is also the instinct that leeks can maintain exuberance in the face of extreme environment, so that the roots can store enough nutrients, which can lay a solid foundation for safe wintering and thus thrive in the next spring. If fertilization is applied at this time, the absorption capacity of the root system will be improved, and the root system will continue to grow leaves, making it mistakenly think that nutrients are sufficient, resulting in insufficient storage materials in the root system and poor growth in the next year.

Third, stop watering.

Before and after the first solar term in first frost, leek was basically in a dormant period, paving the way for wintering. Leek is a tuberous root plant, which is suitable for planting in loose soil. Moisture can promote the rapid rooting of leek, but wet soil is easy to lead to retting. Therefore, it is necessary to stop watering leek when it is near the first frost solar term, which can prevent leek from further rooting, consume energy and spend the winter safely. The leek that will grow next spring is the strongest and fattest.

To sum up, the first frost solar term is coming, and the temperature outside is getting lower and lower. Leek is a kind of vegetable that people like to eat. Its root system is underdeveloped, its taproot is shallow, and its ability to absorb water and nutrients is weak. In order to keep the roots full of nutrients, it is necessary to do the above three stops in the coming spring.
