A brief discussion on the high-yield cultivation and management skills of Niu Di powder ridge

Niulli is a very good traditional Chinese medicine. In recent years, with the shortage of wild medicinal resources, the market supply of traditional Chinese medicinal materials is far from enough. Many people get rich by planting medicinal materials, and Niulli is one of many medicinal materials. So how can high benefits be achieved in planting? The following editor will tell you about the high-yield cultivation and management skills of Niu Di Fan Rong.

High-yielding cultivation techniques of Niudi Powder Ridge

1. Seed and seedling selection

1.1 seed seedlings

In general, the use of seed germination treatment can form a strong seed seedling, there is a main root structure, after truncation, the new lateral root will not form an inflated potato diameter. For the shape of seedlings, the planting effect is not very good, the yield can not be guaranteed, and it will not blossom and bear fruit until about two years after planting.

1.2 tissue culture plantlets

Bovine Dali tissue culture seedlings are mainly produced in batch by means of tissue culture, but at present, the cost of tissue culture seedlings is high and the production quantity is relatively small.

1.3 Cuttage seedlings

There are great advantages in the use of cuttage seedlings, which is beneficial to improve the seed collection effect, ensure simplicity, enhance the overall use effect, and the number of results is very large, and it takes about 3 years to improve the overall yield.

two。 Planting preparation

2.1 site selection

Niu Li needs a lot of water in the seedling stage, and it is necessary to ensure the wetness of the soil. Because the plant does not have the ability to withstand waterlogging, it is necessary to do a good job of drainage in time in the rainy season, and there can be no stagnant water in the depression area. suitable to carry out planting and other work.

2.2 Land preparation

After the cattle vigorously selected the land to weed, mechanical ridges were carried out according to the planting requirements, the depth was about 80cm, the width of rotary grinding with double drills was 60cm, and the row spacing was 150cm. Then dig the drainage ditch according to the terrain. Ridges with 120cm width and 60cm height along the contours. After growing, the cattle can fully absorb sunlight for photosynthesis and promote growth. Wide ventilation can reduce the occurrence of diseases. Ridging planting is more suitable for cattle growth, tuber is more directional, along the powder ridge soil loose ridge growth, tuber concentration is easy to Peng, which is conducive to harvest.

2.3 Base fertilizer

In soil preparation, the application of base fertilizer should be done well, organic fertilizer should be applied with calcium phosphate mixed fertilizer per mu of land, and plastic film should be used to cover it during the actual planting period, so as to improve the overall planting effect.

2.4 Seedling training

Slow seedling treatment should be carried out after the plant comes out of the nursery, and then the planting work can be realized. The seedlings can be sprayed with 400 times carbendazim solution to control diseases and insect pests, and watering should be done after planting to ensure that they can meet the current requirements of seedling management and improve the survival rate of seedlings.

3. Planting technology

3.1 removal Management

At the top of the ridge covered with black film, drill holes according to the density of 600,700 plants per mu, the pore diameter is 12-15cm, and the plant spacing is 80cm, choose the afternoon with weak sunlight to plant, if the cloudy day can be planted all day, first put the seedlings near the planting hole, dig holes, tear open the nutrition bowl at the edge of the hole, and then put the seedling with soil block into the hole and prevent soil from spreading, it is best to choose non-woven bag nutrition bowl. When planting, you don't have to take apart the nutrition bowl and plant directly, which saves time and labor. The planting depth should be one centimeter higher than the nutrition bowl. After planting, the root is fully watered, and if possible, the eyedropper method can be used to water it. Replenish water timely according to weather and soil conditions.

3.2 weeding at the right time

After the completion of the planting work, due to the slow growth rate, herbicides can be used to remove weeds, prevent weeds competing for fertilizer and other problems, and promote the good growth of seedlings. When spraying herbicides, it should be treated in windless weather to prevent the liquid from floating on the plants, resulting in dead seedlings and lack of seedlings.

3.3 Water and fertilizer management

Cattle vigorously have a certain ability to withstand drought, but do not have the ability to resist waterlogging. In the seedling period, if you encounter rainy weather, you should do a good job of drainage, set up drainage ditches to prevent excessive problems of Rain Water, and timely sprinkle water to ensure the survival of seedlings in dry weather. Fertilization management should be done about a month after planting, applying 2kg compound fertilizer per mu, adding 200kg to water, and watering the roots. After three months of planting, 40 jin of compound fertilizer was applied per mu (20 jin of urea and 20 jin of compound fertilizer), a small amount of fertilizer was applied in holes, and then fertilized once every spring and autumn, and the amount of fertilizer gradually increased.

3.4 Branch pruning

The vine type or small shrub type cattle breeds should be managed by pruning branches to effectively control the branch growth. For the plants that can not be propagated, pruning should be carried out to make the nutrients fully supply the root growth, promote the underground potato to bear more seeds, grow faster and increase the yield. In addition to early pruning, the plants with retained seeds were fertilized with a bottle of 30KG spray mixed with water per mu. After spraying for 2-3 times, 8-9 plants planted in March-April entered the flowering stage.

3.5 thinning flowers and promoting fruit

For the buds of cattle, they should be pruned when they grow, there should not be too many spikes, the consistency of the number of plant branches should be ensured, and Yuhualing No. 2 should be sprayed reasonably before flowering, so as to achieve the purpose of flowering and poding. it can ensure the concentrated supply of nutrients to the underground rhizome and realize the reasonable growth of the rhizome. According to the actual growth situation, fertilizer can be applied reasonably to ensure the overall yield and quality.

3.6 Disease and pest control

In the cattle plant growth, there is usually no pest problem, but if there is a high temperature environment, there will be leaf spot disease, you can generally use 50% carbendazim wettable powder plus 80% mancozeb 600-fold liquid spray for control.

3.7 harvesting and processing

For Niu Di, autumn is the best time to harvest. The harvested Niu Da Potato can be stored in 0-5 ℃ cold storage for half a month, and fresh Niu Da Potato can be directly sold or sliced and dried. It can also be vacuum packed with fresh slices to make drinks, soup, wine, and so on.

In fact, Niuli is a very good kind of traditional Chinese medicine, and its planting method is simple, and it is not difficult to obtain high benefits at all. The above is about the high-yield cultivation and management skills of Niudi vermicelli, which growers should learn as soon as possible.
