What are the agricultural activities of rain and solar terms?

As a farmer friend who focuses on farming, what he cares about is how to grasp it. A year's plan lies in spring? Have the key seasons, spring ploughing, spring planting and spring tube, been realized? Plant a millet in spring and harvest 10 thousand seeds in autumn? Desire. The following is Xiao Bian's carefully recommended knowledge about rain and solar terms in north and south agriculture, hoping to help you.

Rain, north-south farming, as far as fields are concerned, rain? Rape and winter wheat generally turned green before and after, and the demand for water was relatively large. However, in North China, Northwest China and Huanghuai areas, the precipitation is generally less at this time, which often cannot meet the needs of crops. If there is little rain in early spring, spring irrigation before and after the "rain" can achieve better results, which is often said that "spring rain (water) is as expensive as oil". At the same time, in the rainy season, for those lands that have not been ploughed in autumn, especially hard stubble lands such as grain stubble and rice stubble, it is necessary to take advantage of the opportunity of thawing to mop the stubble land with a pull (a tool for dragging stubble in rural areas, made of strips or branches), or press the stubble with a roller, and then drag it down for rolling, which can not only ensure the sowing quality, but also achieve the effect of drought resistance and moisture conservation. In the area south of Huaihe River, there is usually a lot of rain at this time, so it is necessary to do a good job in clearing ditches and draining farmland, weeding in intertillage and so on to prevent wet damage and rotten roots. Seedling raising of double cropping rice and early rice in South China has started. In order to prevent the harm of cold and hot weather to seedlings, we should pay attention to the "cold tail and warm head" weather, seize the sunny day to sow and strive to protect seedlings once.

Main management measures:

1. The weather is cold, so it is necessary to strengthen anti-freezing and warmth, but also pay attention to ventilation to prevent seedlings from being stuffy.

2. Properly control fertilizer and water to prevent seedlings from growing white, but not too much, otherwise it will affect the growth of seedlings and appear thin, small and yellow seedlings.

3. The garbage mud, manure and human manure used in seedbeds and nutrition bowls should be fully decomposed, otherwise it will spread diseases or attract pests or burn the roots of seedlings. Seedbed fertilization should not be applied with raw fertilizer or agricultural fertilizer. Pay special attention to the concentration when using chemical fertilizer, and enough is enough.

Rainwater prepares for agriculture. Rainwater is a critical period for Koharu to manage and Da Chun to prepare for agriculture. After the solar term of rain, the temperature began to rise, the wheat began to turn green from south to north, and the water vapor in the soil continued to rise and condense on the soil surface, freezing at night and melting at day, and began to return to pulp. Due to the increase of rainfall, humid air and warm weather, it is very suitable for the growth of all things and has a great influence on the growth of overwintering crops. An agricultural proverb says: "Rain and rain are good crops, and Da Chun and Koharu are treasures." According to the weather characteristics, the vast rural areas should carry out weeding and fertilization on the middle tillage such as Sanmai, clear ditches and bury soil moisture to prepare for drainage and waterlogging prevention.

Before and after rainfall, rape and winter wheat generally turn green and grow, which requires high water content. ? Spring rain is as expensive as oil? At this time, suitable precipitation is particularly important for crop growth. At this time, the precipitation in North China, Northwest China and Huanghuai areas is generally less, which often cannot meet the needs of agricultural production. If there is little rain in early spring, the best economic benefit can be obtained by timely spring irrigation before and after the rain. In the area south of Huaihe River, it is mainly to strengthen intertillage and hoeing, and at the same time, do a good job in clearing ditches and draining water in the field to prevent excessive spring rain from causing wet damage and rotten roots. As the saying goes:? Wheat seedlings, vegetable flowers? The coated rape should be topdressing with moss fertilizer in time to compete for the weight of multiple pods. Seedling raising of double-cropping early rice in South China has begun, so pay attention. Cold tail and warm head? Grab the sunny day to sow, and strive to sow all the seedlings at once.

Rain is solar term, and the weather is changeable, which is one of the seasons with the most cold waves in the whole year. The cold and hot weather at first is very harmful to the growth of crops, forests and fruits that have sprouted and turned green. Attention should be paid to the cold and antifreeze work of crops, greenhouse vegetables and public transport departments.

That's right. Rain and spring rain are as expensive as oil, which can prevent soil moisture from flowing, accumulate more fertilizer and grain, select fine varieties and win a bumper harvest. ?

Agricultural tips in various places: South China's double-cropping early rice seedling raising 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. This kind of hot and cold weather is 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 also pay attention to personal health care to prevent some diseases from spreading in late winter and 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. It is timely to graft fruit trees and plant trees. After the winter drought, there are many droughts in spring in South China all the year round, especially in the west of South China? Spring rain is as expensive as oil? . In agriculture, attention should be paid to moisture conservation and timely irrigation to meet the water supply at the jointing and booting stage of wheat and the critical period of bolting and flowering of rape. The mountainous area of the northwest plateau is still in the dry season, with low temperature and high wind speed, which is prone to forest fires.
