What dish is best for open-air growth in March?
Due to the different regions, the temperatures in the north and south are different, and the climate in each province is also different. For example, in Zhejiang, Guangdong, Henan, Hangzhou, Shandong, Hunan and other regions, the climate after spring is still very different.
So in March of the solar calendar, some vegetables can be planted in the open air in the south, but not necessarily in the north. Today, I will introduce you to the vegetables suitable for the growth of the north and the south in March.
Chinese chives
The planting season of leeks is spring, summer and autumn. Generally, the planting time in spring is between March and May, and it can be planted when the temperature is stable above 15 degrees. Therefore, during March, basically all plants can be planted except in cold areas such as Northeast China and Inner Mongolia.
cucumber
The planting time of cucumber begins in March and lasts until August, covering three seasons: spring, summer and autumn. When planting, the temperature should be kept above 15 degrees, preferably around 20 degrees.
From the temperature point of view, cucumber can be planted in the open air on a large scale in March in the south, and planting in some colder areas in the north will be postponed until April-May.
If vegetable farmers grow cucumbers, they usually buy cucumber seedlings and transplant them. If it is a seedling production enterprise, it will choose to raise seedlings in greenhouse in advance.
When it was sold in March, the survival rate of vegetable farmers transplanting cucumber seedlings was also relatively high. It is suggested that when buying seedlings, Miao Zhuang, big seedlings and seedlings with good growth should be given priority.
Chinese cabbage
The planting time of Chinese cabbage is mostly in spring and autumn, and it is usually planted in March-April in spring. The temperature of Chinese cabbage and cucumber is similar, so it is better to keep it above 15 degrees or better.
Moreover, Chinese cabbage is not tolerant to low temperature, so in order to improve the survival rate, temperature is very important. Southern and central areas can be planted properly in March, and planting in northern areas will be postponed until April.
For vegetable farmers who grow cabbage on a large scale, it is mainly to avoid risks. In addition, the price of Chinese cabbage changes greatly, with only 2-3 cents per catty in cheap years, and above 1 yuan per catty in expensive years.
Fried green beans
Mung beans are also called kidney beans. Although the name is "Four Seasons", they can't be planted in the open air all year round (except in greenhouses).
In the open air, the sowing time of green beans is concentrated in spring and autumn, and the spring time is usually from February to April. According to the temperature difference between north and south, green beans can be planted in Central China and Southwest China in March.
The Huanghuaihai region was postponed to April, and the northern plateau region was postponed to May. Autumn sowing time is generally concentrated in July-September, and the suitable sowing date is selected according to the specific situation.
Tricolor amaranth
Spring is the season to eat wild vegetables, and amaranth is essential. The time for planting amaranth in the open air began in March and lasted until August. Of course, the planting time of amaranth is related to the temperature in different regions, and it can also be related to varieties.
It is understood that amaranth and amaranth can be planted in March. Friends who want to grow amaranth can hurry up.
shepherd's purse
At present, the area of artificial shepherd's purse is gradually increasing, and it can be planted in spring, summer and autumn. Shepherd's purse has strong adaptability and does not need special management after planting. It can be planted when the temperature is above 20 degrees.
Therefore, during March, some friends who want to plant shepherd's purse can get good yield by choosing the right site without too much fertilization management.
Crown daisy
Chrysanthemum can be planted all year round in the south, and the planting time in the central and northern regions is concentrated in spring, summer and autumn. March is the sowing time in spring, which is a semi-cold-tolerant vegetable.
If the sowing temperature is low, it is not conducive to growth. So in March, when the temperature rose above 15 degrees, we planted chrysanthemums in the open air.
tomato
The planting time of tomatoes is mainly concentrated in spring and autumn. Of course, according to different regions, March-May is the peak of spring sowing.
To plant tomatoes, you can choose to buy seeds for sowing or buy seedlings for planting. For ordinary vegetable farmers or their own small vegetable gardens, it is recommended to buy seedlings for planting. Relatively speaking, planting is relatively easy.
Lettuce; lettuce
Lettuce likes a cool but not cold environment. Therefore, spring and autumn are the seasons for planting lettuce, and the sowing time in spring is February-April.
In February, it is mainly in the southern region, which can be extended to the Huang-Huai-Hai region in March and basically to the northern region in April.
The cultivation of lettuce is relatively simple, the root system is relatively developed and the drought resistance is better. Moreover, it is also easy to grow lettuce. After purchasing seeds, sow them directly in the soil and cover them with thin soil.
Small carrot
Radish can be planted all year round. March belongs to spring radish. According to different varieties, the growth period is long and short, 1-2 months.
When planting spring radish, the temperature is stable above 15 degrees. If the temperature is too low, on the one hand, it will affect seedling emergence.
On the other hand, the radish grows weakly, which leads to the radish not growing up. If the local warming time is late in spring, the planting time can be postponed appropriately.
