Solar term autumnal equinox news

The solar term is the coldest time of the year, so what should we pay attention to in farming activities at this time? During the cold solar term, we should continue to cultivate spring flowers, do a good job of frost and moisture prevention, and strive for a bumper harvest of spring flowers; In order to prevent the damage of snow and freezing rain to bamboo forests and fruit trees, it is foggy and windy in winter, so special attention should be paid to safety when fishing and breeding at sea or in rivers and lakes. What should we pay attention to in small-scale cold farming activities? What is the second farming activity? Let's have a look!

What should we pay attention to in the farming activities of Xiaohan?

In the mild cold season, the southern region should pay attention to the winter application of wheat, rape and other crops, and do a good job in preventing cold and freezing, accumulating fertilizer and building water conservancy projects. In Hainan and most parts of South China, it is mainly to prevent cold and freeze, accumulate fertilizer and build water conservancy projects. In some areas, we should pay close attention to the field management of overwintering crops and pay attention to the antifreeze and heat preservation of livestock.

Artificial mulching in winter is also an important measure to prevent freezing injury of agricultural and forestry crops on the basis of pouring frozen water, applying sufficient winter fertilizer and cultivating bacon before winter. When the cold wave or strong cold air comes, pouring sparse manure and clearing plant ash can effectively reduce the harm of low temperature to rape. Vegetable fields cultivated in the open field can be sparsely spread on vegetable beds in winter as long-term plastic film, which will not affect the light, reduce the wind speed between vegetable plants, prevent the loss of ground temperature, and play the role of heat preservation and antifreeze. The low temperature is coming, and the thick cover is temporarily covered.

What are the farming activities of Xiaohan?

Slight cold is the best time to plant cinnamon.

The slight cold and severe cold in the lunar calendar every year are the best time to plant cinnamon. After about four years, cinnamon can be harvested. Cinnamon is a medicinal plant, and it is full of treasures. Xijiang cinnamon and cinnamon oil made from cinnamon are well-known spices and medicinal products in the international and domestic markets.

Flower promotion and fertilization of litchi before and after slight cold

As far as the phenology of litchi is concerned, it is generally from 165438+ 10 to 65438+ 10 in the following year. At this time, it is necessary to apply flower-promoting fertilizer to litchi, mainly to enhance the nutrition of the tree before flowering, promote the differentiation of flower buds, form strong ears and improve the fruit-setting rate. The fertilizing period of flower-promoting fertilizer is generally 10-20 days before flower bud differentiation.

The flower bud differentiation of "glutinous rice" litchi in Dongguan county is 65438+February15-65438+10.5, and the flower-promoting fertilizer should be applied on June 5438+10.25-June 65438+February 25. The flower buds of "Zhuangyuanhong" litchi in Fuzhou City, Fujian Province began to differentiate from1October1to 165438+20, and should be applied from1October 10. The flower bud differentiation time of "Zhu Lan" litchi in Zhangzhou is from mid-June to mid-February.

Because it is difficult to know the flower bud differentiation period of different varieties and different regions, it is advisable to apply flower-promoting fertilizer before and after the slight cold in early June of 1 and before and after the severe cold in late June of 1. The types of fertilizers are slow-acting fertilizer and quick-acting fertilizer, farmyard manure and chemical fertilizer. Usually, 50~ 100 kg of decomposed human manure and 0.25~0.5 kg of nitrogen fertilizer are applied to each plant.

It is most suitable to sow spring cabbage 10- 15 days before slight cold.

In North China, the suitable sowing date of cabbage stubble in cold shed in early spring is from the middle and late February to the middle and early October of 10-15 days before slight cold after sowing. Generally, seeds do not need to germinate before sowing. Dry seeds can be sown. First, water the seedbed. After underwater infiltration, the surface of seedbed is filled with nutrient soil again. Then, the seeds should be sown evenly. After sowing, the screened medicinal soil should be covered to keep moisture and prevent the seedbed from cracking. The seeding rate of seedbed is 3 ~ 4g per square meter. Sowing amount should be strictly controlled to prevent seedling thinning due to excessive density.
