Every time the rural land is planted, the growers are smashed their heads and want to plant a good harvest in their own fields. However, no one can think of it, just when others are smashing their heads. Wu Qiang has already made money easily. It turned out that Wu Qiang was busy when the big guys were busy cultivating the land. He has another one. Planting yam is coming. They all say that people are bold and productive. This is really a lie. Let us also look at how to produce high-yield yam.

How to grow greenhouse yam

1. If the shed yam is cut with yam tubers, we can use the lime powder in the incision in time to prevent disinfection. When you plant the next one, you have to make a bud with a piece down, and a large piece of the size down. This will ensure that the buds will come out.

2. Before sowing, use 500 times liquid carbendazim or 72% chlorothalonil 1000 times solution for 3-5 minutes, dry and then seed.

3. Field management: If you use more base fertilizer. You can use less fat or no topdressing. This is to ensure the high yield of yam. Generally can be topdressed 2-3 times. When the crop grows to about 1 meter, it is applied once for high-nitrogen compound fertilizer. Then apply it once every week or so.

4. Yam expansion period: mainly multi-element compound fertilizer with more phosphorus and potassium fertilizer, about 30 kg per acre. It is generally recommended to use the method of flushing.

5. Late growth: 0.2% potassium dihydrogen phosphate and 0.1% urea can be sprayed on the foliage. This will prevent the premature aging of yam. When applying fertilizer, attention should be paid to the application of shallow soil, which is the best position for the absorption of yam roots.

6. Scaffold weeding: The yam is covered with 6-10 cm of floating soil after sowing. Then use 150-200 g of special herbicide for yam to spray evenly with 100 kg of water. Then cover the mulch.

7. Watering: If the yam is too dry, it will directly affect the expansion of yam. Especially during the expansion period of yam, the time is from mid-April to late May. During this period, watering is usually carried out for about 10 days. After the end of May, it is necessary to properly water the soil according to the soil moisture.

The growers have mastered the high-yield planting techniques of the shed yam, and then do the field management and fertilization methods of yam. High yield of yam is not a problem.
