Sweet potato is also called sweet potato. It is a kind of crop that is easy to grow in food products. The yield of random planting is also very good. Now the use of sweet potato is promoted. Sweet potato leaves are also a very delicious vegetable, while sweet potato can be made. A variety of food, the current market demand for sweet potatoes is still quite large, let's take a look at the sweet potato planting time and planting methods, let's take a look.
Planting time
Sweet potatoes are generally harvested in the autumn and winter seasons. After a long period of growth, for example, they must first be seeded, then cut, and finally formally grown. The time for planting sweet potatoes is usually between April and May of each spring. The best time to sow is in mid-May. At this time, the temperature is basically stable at 15 to 20 degrees. In this case, the sweet potato can be planted. Rapid sprouting.
Planting method
1, choose the species
Although the sweet potato planting seems simple, the selection of the seed is also the basic condition for the high yield of sweet potato, and it is also the basic requirement for its rooting and germination. When selecting seeds, we usually choose larger sweet potatoes. The first is to observe whether there are any defects in sweet potato seed potatoes, or where they have been bitten by insect mice. If not, then continue to see how many buds grow from sweet potatoes. The vitality is not strong, so basically it can be.
2, sowing
When sowing, the sweet potato seed potato is soaked in the polylinguistic solution for ten minutes, which can effectively prevent some diseases, and can also prevent the seed potato from being stolen by the mouse before it has germinated, and then it is planted and sowed. When we have to distinguish between the head and the tail, otherwise the seedlings will not come out, if it is really unclear, it can be placed obliquely. Finally, the seed potato is covered with a layer of dry grass rot, then a thin layer of The soil can be covered, if we are afraid that the temperature is not up to the requirements, we can cover it with a film. When the sweet potato seedlings grow out for thirty or forty centimeters, we will cut them down, and then cut the three leaves into sections to cut into small sections. The cuttings are usually about 30 centimeters per plant.
3, fertilization
After the planting, it is necessary to carry out the first fertilization. The fertilization is mainly to make the new sweet potato seedlings grow new roots, so it is generally applied human waste water, and the second fertilization is after the sweet potato survives, because The growth is different, so it looks uneven. This time it is mainly for Qi Miao. Urea is generally used. The third fertilization is to raise the seedling fertilizer and urea. But it needs to add some compound fertilizer. Finally, it is the most important strong fruit fertilizer. Potassium and boron fertilizers are generally used.
4, Shun Miao
In order to facilitate the subsequent harvesting and to consume unnecessary nutrients, we have to carry out the seedlings of the sweet potato seedlings in the field, and clear the sweet potato vines in the field in one direction, so that they are long in one direction, so that they are harvested in time. There will be a lot of time, and then it will be good to remove some extra leaves when Shun Miao.
5, prevent disease
Commonly affected by the growth of sweet potatoes are leaf curlers and aphids as well as scorpions and voles. Leaf curlers and mites generally harm sweet potato leaves and affect photosynthesis, while 蛴螬 and voles generally prefer to eat sweet potatoes in the fields, which will bite the sweet potatoes in the field one by one.
Generally, it is good to use the trichlorfon solution for the pests that damage the branches and leaves. However, the effect of killing such things is not great for the voles. Therefore, it is generally used to trap and kill the rodent's favorite food in the field. Booby.
6, harvesting
Harvesting is generally in September. First, we must cut the sweet potato seedlings, and then dig out the sweet potatoes. The sweet potatoes that are dug out are generally stored in the mantle, otherwise the water is easily lost and is easily rotted.
