Why do you need to plant green manure? What are the benefits of planting green manure? Nowadays, green manure does not mean traditional fertilizer. However, in order to increase crop yield, reduce fertilizer use, improve soil fertility, and increase economic benefits, many farmers choose to plant green manure to achieve fertilizer effect. Now that winter is coming, many green manures cannot be planted, so we need to choose something that is good for winter, that is, winter green manure.

Winter green manure refers to green manure that can be used in autumn or early winter, and in spring or early summer. Half of its entire growth period is in winter, so we all call them winter green manure. So, which plants are called winter green manure? How to plant green manure in winter? If you want to have high yields in green manure, you must grasp the key points to plant it. Let me give you a brief introduction.

Vagina

1. The most common winter green manure variety:

1. Vagina: Vagina is an annual or annual herb, mainly distributed in Yunnan, Sichuan, Hubei, Guizhou and other places where I have lived. It is generally used to sow in the autumn rice fields or plant between the cultivated crops. It is one of the important green manures in orchards in the north and south of my country. The sweet potatoes are mainly sown in autumn, and can be sown in spring in North China and Northwest regions. The suitable temperature for germination is around 20 degrees. The roots of the sweet potatoes will form nodules 10 to 15 days after the emergence of the seedlings. The appropriate temperature for flowering is 15 to 20 degrees, and the sweet potato's cold resistance is stronger than that of Ziyunying. Vagina has less strict requirements for the soil planted. It can be planted in loam, sand and clay, and has strong barren tolerance. As a green manure overwintering, Vagina plays an important role.

You can also choose to sow in early spring. In winter, there are suitable temperatures in the south. The sowing volume is about 1.5-2kg per mu. Before sowing, stir the seeds and fine sand evenly and then sow. Planting rat thatch for 4 to 5 years without weeding can greatly reduce the cost of weeding, improve the quality of fruits, enhance soil fertility, and achieve the effect of increasing yield.

Before sowing, seeds should be dried for 4 to 5 hours. Rhizobia should be used to mix seeds to improve their nodule growth and nitrogen fixation ability. When the plant decomposes, cymbidium can produce a large amount of nitrogen in the excitation soil, which plays an important role in maintaining the nitrogen cycle in the farmland ecosystem.

2. Advantages brought by planting green manure:

Choose green manure to plant green manure first, you must first understand its characteristics, pay attention to its growth period and stress resistance. Green manure can bring rich nutrients to the soil.

⑴Improved soil: Planting green manure can improve soil structure, improve soil fertility, retain water and fertilizer effects, and reduce soil erosion.

⑵ Low investment and low cost: Planting green manure only requires a small amount of seeds and fertilizers, and no large amount of other traditional fertilizers is required, which reduces the cost of artificial weeding and fertilizers.

⑶ High quality and good fertilizer efficiency: Green manure is rich in organic matter, containing nitrogen, potassium, phosphorus and a variety of trace elements, which can increase yield on crops.

⑷ High utilization rate: Green manure can also be used as forage to feed livestock, and livestock manure can be used to fertilize the fields, promoting each other, and increasing the development of animal husbandry.
