2. Selecting germination: According to the local climatic conditions, select the appropriate variety of yam, whether it is the use of yam mouth or yam stalks, all must be budding before the next species, and only choose to stay one robust. This is one of the major differences between yam punching and traditional planting.
3, soil preparation fertilization: the same with the traditional method of planting. Field fertilization must be completed before drilling.
4. Punch: The spacing and spacing of holes for punching are related to the yam variety, land fertility and planting habits. Generally, the plant spacing is 25 to 30 centimeters. The row spacing is wide and narrow, and the width is generally 80 to 90 centimeters. Narrow lines are generally 50-60 cm. The pore size is generally 6 to 12 cm and the depth is 80 to 140 cm, which is entirely related to the yam variety.
Before drilling, shovel a flat ditch with a depth of 10 cm and a width of 20 cm with shovels and put the shoveled soil aside. This is a nutrient-containing soil for burying the seeds of yam. Then use the punch to drill holes at the required distance and depth. Due to the close spacing of the holes, it is very easy to throw the soil that was thrown out into the previous drilled hole when drilling, so use the foot to plug the hole that has been drilled, or use a piece of wood or iron to block the hole. mouth. Drill the earth out with a spade shovel to the other side.
5, the next species: the hole covers covered in the hole (hole cover can be made of easily decayed crop stalks, can also be used injection parts; hole cover is larger than the hole diameter 30 ~ 50 mm, hole cover center to stay There is a hole with a diameter of 20-30 mm. Sprinkle 5 to 10 mm thick nutrient soil on the surface. Put the yam or yam mouth of a good seedling into the soil. The bud must be aligned with the hole of the hole cover so that the hole can be covered smoothly. Into the hole. Then cover the top with 150 to 200 mm of nutrient soil. Ditch the nutrient soil ditch for the next line to dump out the mud.
6, maintenance management: maintenance management and traditional planting. Note: When pouring the ground, do not use full water to avoid pouring holes! Yam itself is also afraid of embarrassment. If it does not collapse, the sandy soil can generally be used continuously for 2 to 3 years, and the clay soil can be used for 3 to 4 years.
The use of perforating methods to grow yam has the following advantages:
A. Increase production by about 30%;
B. To improve the quality of yam, the appearance of yam grows round and thick and straight, like the machine does;
C. greatly reduce the labor intensity and reduce the harvesting harvest time, harvest, do not need to dig manpower, just to remove the floating soil at the surface of the yam, you can directly pull out the hand, each person can harvest about an acre a day; Reduce harvesting costs by more than 80%;
D. Reduce the cost of planting. A hole can be used for 2 to 3 years. A machine can make an acre for 4 to 5 days. The cost for drilling an acre of land is only 400 to 500 yuan (labor cost 200, gasoline 100, equipment depreciation and consumables consume 200 yuan) If the hole is only used for 2 years, the perforation cost per hole is 250 yuan, if you use it for 3 years, the per-mu hole cost is only 170 Multiple
E. Yam hole cultivation is not limited by soil, where it can be grown, as long as its nutrients are suitable for yam growth;
F. The cultivation method is simple and easy to learn. The drilling machine is cheap and reliable.
1. Prepared land: The land to be used for yam cultivation should be prepared and the ground should be leveled to facilitate drainage. Apply the base fertilizer before the next planting, and use the farmyard fertilizer as the primary fertilizer. Fertilization and ploughing can be carried out after the autumn of last year, at the latest in the first half of the next season. Before planting, there must be a certain amount of bottom soil. There is no difference between preparation and traditional planting methods.
