What vegetables are suitable for planting in rainy season?

After the solar term of rain, the sun is the spirit, the rainfall begins to increase, and everything is full of vitality, which is very conducive to the germination of seeds. Rainwater solar terms are suitable for planting: spinach, spring potato, lettuce, coriander, Chinese cabbage, leek and so on.

What vegetables are suitable for planting in rainy season?

First, spinach

Spinach is rich in nutrition. It is a typical vegetable that likes to enjoy the cool. Seeds are difficult to germinate when the temperature is too low, and flowers are easy to bloom when the temperature is too high. The optimum growth temperature is 15 ~ 22℃, which is very suitable for sowing after rain and saves solar energy.

The cultivation of spinach is very simple. Before sowing, the seeds can be soaked in cold water for 12 hours to make the seed coat absorb water and soften, which can accelerate the emergence of seeds. When sowing, select soil with strong water and fertilizer conservation ability, apply fully decomposed farmyard manure, rake the soil evenly and finely, then scatter the seeds on the soil, rake the topsoil lightly with a toothed rake (so that the seeds are buried in the soil), and thoroughly irrigate the soil.

Second, spring potatoes

Potatoes, also known as potatoes, are rich in nutrition and complete, and are important vegetable crops and food crops in China. Potatoes like cold climate. Tubers can germinate when the temperature is above 5℃, and the most suitable temperature for growing period is 17 ~ 22℃. Therefore, it is also a suitable sowing time for spring potatoes after rain, and they can be harvested three months after sowing.

To achieve high potato yield, we must first strictly select seeds, and choose potatoes without disease spots, deformities and eye necrosis as seeds. Then, we cut the potatoes into 30-50 grams. The slice is too small, the growth of potato seedlings is weak, and the slice is too large, which increases the planting cost. Secondly, the soil in YEATION, with deep soil layer, loose structure and rich organic matter, is suitable for planting potatoes, and the soil with large porosity is very conducive to the full expansion of tubers; Third, when planting potatoes, we can use plant ash for seed dressing. Plant ash can not only prevent seed rot, but also be used as seed fertilizer to prevent the occurrence of element deficiency.

Third, lettuce.

Lettuce is tender, crisp and refreshing, so it is named because it is suitable for raw food. Lettuce is neither cold-resistant nor heat-resistant, and it is also a typical cold-loving vegetable. The optimum growth temperature is 65438 05 ~ 20℃. When the temperature exceeds 25℃, the leaves will become old and bitter, which is very suitable for planting after the rain is solar-saving.

Lettuce likes humidity. When the soil is wet, the leaves will become tender and juicy. Lettuce should also be watered frequently during the growth period to keep the soil moist as much as possible. Lettuce can be divided into wrinkled lettuce and bulbous lettuce. For wrinkled lettuce, nitrogen fertilizer can be given priority. For lettuce with heading, it is also necessary to apply potassium fertilizer, and 400 times of potassium dihydrogen phosphate can be sprayed at the beginning of heading.

Fourth, coriander

Coriander is an important seasoning vegetable in our life, and also a cool vegetable. The most suitable temperature for the growth period of coriander is 15 ~ 25℃. We can rest assured that it is solar energy saving when planting after rain.

Coriander is divided into big leaf coriander and small leaf coriander. The yield of coriander is high, but the smell is light. Although the yield of coriander is low, it is rich in flavor. Many people grow coriander, which is caused by no broken shell. The seeds of coriander are wrapped in a thick seed coat, so it is difficult to germinate directly. We can crush the seeds of coriander in glass bottles and soak them in cold water 12 hours before sowing.

Five, Chinese cabbage

Chinese cabbage likes cold climate and has a short growth cycle. It can be eaten more than 20 days after sowing, which is very suitable for planting in spring and autumn.

The planting method of Chinese cabbage is very simple. We only need to choose the soil with high organic matter content and strong water and fertilizer conservation ability, and then plant the soil after finishing the land. Chinese cabbage rarely gets sick during the growing period, and the main pests are flea beetle, aphid, cabbage caterpillar and so on. For pests, we can carry out green control by spraying tea bran water or plant ash.

Special attention: Chinese cabbage has a shallow root system, which is neither drought-tolerant nor waterlogging-tolerant in the growth period. It should be irrigated with small water frequently, and nitrogen fertilizer can be applied topdressing in the growth period.

Six, leeks

Leek is rich in nutrition and has high edible value and medicinal value. Many people like to grow in the countryside. Leek can be propagated asexually with roots or sexually with seeds, which grows slowly and cannot be harvested after transplanting that year, so we can plant it with "leek roots".

Leek is cold and heat resistant. As long as the soil is not frozen, leek roots can be transplanted all year round. When transplanting leek roots, the fibrous roots and stems and leaves should be cut off, which can not only prevent nest roots, but also promote root regeneration and improve the survival rate of leek root transplantation. Leek has strong regeneration ability. When the nutrients are sufficient, it can be cut one after another, and it can be "knife topdressing" if conditions permit.

Meteorological changes of rain solar terms

Rain solar term means the beginning of rainfall, but the rainfall level is mainly light rain or Mao Mao rain. In rainy and solar terms, the direct point of the sun is gradually approaching the equator from the southern hemisphere. At this time, the sunshine hours and intensity in the northern hemisphere are increasing, and the temperature is rising rapidly. Warm and humid air from the ocean becomes active and gradually pushes northward. At the same time, cold air is not to be outdone in the weakening trend, and it frequently competes with warm air to form rainfall.

From the meteorological point of view, the highest temperature in most parts of China can generally rise above 0℃ after rain. Although it has entered the spring rain solar term, there is no breath of spring in most parts of northern China. The average temperature in many areas of South China is above 10℃. At this time, rape, winter wheat, etc. Generally, it will turn green, which requires higher moisture. As the saying goes, spring rain is as expensive as oil, and suitable precipitation is very important for the growth of crops. At this time, the precipitation in North China, Northwest China and Huanghuai areas is generally less. If there is little rain in early spring, timely irrigation after rain is beneficial to crop growth.

Because China is different, some areas are in early spring and some areas are in late spring. Snow is an important symbol of winter, and it is still snowing in some parts of northern China, and it is still very cold. The solar term with the heaviest snow in the middle and lower reaches of the Yellow River and its vicinity is neither a light snow nor a slight cold (because the temperature was low at that time and there was less water vapor in the atmosphere), but a solar term in the spring rain in late February.

The southwest and most of the south of the Yangtze River is a scene of early spring, with warm sunshine and green fields. South China is full of spring and flowers are in full bloom. Spring scenery is everywhere in southern Yunnan.

Anti-freezing measures to save rainwater

Seedling raising of double-season early rice in South China has begun, and the rainy season and weather are uncertain, which is one of the seasons with the most cold waves in the whole year. Hot and cold weather and warm and cold weather are very harmful to the growth of crops, forests and fruits that have sprouted and turned green and people's health.

While paying attention to the cold and antifreeze work of crops, greenhouse vegetables and industrial and commercial departments, we should still pay attention to personal hygiene and health care to prevent the prevalence of certain diseases in early spring.

Rainy solar terms are the origin of the twenty-four solar terms in the Yellow River basin. Before the rain, it was very cold, but the snow was flying and the rain was falling, which was unpleasant.

After the rain, the temperature can generally rise above 0℃, with less snow and more rain.

However, in the warm southern region, even in the dead of winter, rainfall is not uncommon. The average temperature in most parts of southern China in this period is above 10℃, peaches and plums are in bud, and cherries are in full bloom. It is indeed a climatic spring.

In addition to a few years, the frost period has come to an end.
