Spring is coming

Today (4 February) at 10.42 hours

Usher in the Start of Spring solar term

Start of Spring is the first of the 24 solar terms

At this time, the earth gradually wakes up

Things begin to recover

After the start of spring, vegetable production is in seedling planting period, what should be noticed?

First, strengthen sowing time management, improve seedling emergence and seedling rate

The planting period of melon vegetables should avoid cold weather and choose 3-4 days before the fine weather when the seeds are exposed and emerging. Heating equipment is used when sowing, and small arch shed is built after sowing to keep heat and increase application. Turn down the appropriate temperature in time after vegetable emergence to prevent vegetable seedlings from growing and reduce the rate of seedling formation. Watering available greenhouses in the spare water, so you can prevent the hot seedling ice water caused by seedling "cold". If vegetables appear because of low temperature and high humidity caused by rational disease, according to the weather conditions to properly supplement the fertilizer water, promote seedling recovery.

Two, pay attention to reasonable ventilation and light

With the warming of the weather, the temperature and humidity in the greenhouse will be increased at the same time, but too high temperature and humidity in the shed is not conducive to the normal growth of vegetables, but also easy to induce vegetable diseases and pests. Therefore, if the external weather conditions allow, attention should be paid to strengthen the ventilation and light management in the shed, so as to reduce the temperature and humidity in the shed and increase the amount of lighting of vegetables in the shed. At the same time, harmful gases such as sulfur dioxide and ammonia accumulated in the shed can also be removed from the shed in time. However, during ventilation, attention should be paid to choosing noon in the daytime when the temperature is higher, and cold wind should be prevented from blowing vegetable plants directly to prevent the temperature from plummeting and affecting the normal growth of vegetables.

Three, pay attention to the method of vegetable planting

Spring temperature and humidity is more suitable, less suitable for the vigorous growth of crops, whether sowing seedlings, or transplanting, attention should be paid to strengthen the management of water and fertilizer, to ensure that there is sufficient nutrient supply for vegetable germination and growth, and to enhance the cold resistance of vegetables.
