Cultivation techniques of Golden Needle

Golden Needle is what we call cauliflower in our daily life, and the planting area in our country is very large. Golden Needle is a very traditional vegetable in China, which has a long history of eating in China. Therefore, the current market demand is also very large, and there are naturally more and more people planting. So how to grow Golden Needle? The following editor brings you the cultivation techniques of Golden Needle, let's have a look!

1. Soil selection

The climate of the origin of Golden Needle is relatively warm, but it has strong cold tolerance. Although the stems and leaves of Hippophae rhamnoides die in autumn, its roots spend the winter in the soil. Although its soil adaptability is very strong, but if you want to ensure high yield, it is necessary to choose fertile, deep, loose and strong water and fertilizer conservation soil for cultivation. It is best to have a certain shading ability to provide a good growth environment for Golden Needle. After selecting the soil, do a good job of soil preparation, deep disinfection, eliminate the germs in the soil, and prevent harm to the growth of Golden Needle.

2. Methods of reproduction

The propagation method of Flammulina velutipes is mainly split propagation, which usually begins when the old buds of the plant grow to about 10 cm in spring. In ramet, at least two corms should be planted as one plant. When planting, we should pay attention to control the planting density, and the plant row spacing should be controlled at about 10-15 cm. Then according to the size of the bulb to control the size of the planting hole, the depth to bury the bulb. Before planting, sufficient farm manure should be applied to each planting hole, and the dosage should be controlled at about 1-2 jin. Then pour enough water after planting to improve the survival rate.

3. Field management

The growth ability of Golden Needle is relatively strong, and the management can be properly extensive when planting. However, there are also many things that need our attention. The first thing is to do a good job of ploughing and cultivating soil. Because the root of cauliflower is fleshy root, soil fertility and looseness have a great influence on the root development. Therefore, during the planting period, we should plough reasonably according to the consolidation of the soil. Then it is necessary to do a good job of topdressing, at least three times during the whole growth period, and feces are carried out in various important periods such as seedling emergence, bolting, budding and so on. Finally, it is necessary to control the moisture and keep the soil moist, but the moisture should not be too much, and drainage measures should be taken in the rainy season to prevent root retting.

4. Timely harvest

In the same year of planting, if it is properly managed and grows normally, it can blossom. However, it is not suitable for harvesting in that year, and it usually does not begin until the next year. The picking time should be carried out every morning, and it is the best time to harvest when the flowers are not yet fully unfolded. Under normal circumstances, the yield of each plant is about 3 jin. The total output of fresh flowers is 3000 jin, and the flowers of 5kg can be dried into 1 jin of dried flowers, so the dry yield is about 300jin. After harvest, processing measures should be taken to steam it, but it should not be excessive and the storage time should not be too long.

The above is a brief introduction to the cultivation techniques of Golden Needle. In fact, the planting technology of Golden Needle is relatively simple, as long as the normal management, its benefits are very good. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
