The whole process and method of sweet potato planting

1. Select marketable varieties with high yield for seedling raising (spring planting) or seedling cutting.

2. To plant sweet potato seedlings, the plots should be sorted out first. If it is planted in spring, the plot is high, there is no stagnant water or good drainage, try to use plastic film cover cultivation. The soil of the plot should be loose and fertile, and it is advisable to choose well-drained and loose sandy loam.

3. Apply plantar fertilizer, farmhouse fertilizer and compound fertilizer should be applied appropriately. Generally, 4000kg of well-rotted high-quality farm fertilizer, 20kg of diammonium phosphate, 30kg of urea, and 7 12kg of potassium sulfate are applied per mu.

4. To do ridges, it is generally to take high ridges and double rows of dense planting, with a ridge height of 20 25 cm, a ridge width of 60 80 cm, and a ridge spacing of 15 20 cm. The ridge surface is required to be smooth and meticulous. The double row is covered with polyethylene mulch with a thickness of mm and a width of 110 cm.

There are also single-ridge cultivations.

5. Mulching and seedling: Here are those who are planted first and then mulched, and there are also those who are mulched first and then planted. Each has its own advantages and disadvantages, the former is mostly used for artificial planting, which is more labor-saving; The latter can be mechanically laminated, and the temperature is increased in advance to ensure picking. The water in the planting hole must be watered enough to avoid drought during the seedling period.

6. Put the sweet potato seedlings in the planting hole, water them thoroughly, bury the stems and roots at the bottom with soil, and expose 3 4 leaves on the ground. Sweet potato seedlings are very good to survive, even if the seedlings of sweet potatoes are cut off, and cuttings can be carried out directly, cuttings propagation is a common method of sweet potato planting, as long as there is no lack of water, it is very good to take root. It is necessary to keep the soil moist at the seedling stage, and long-term drought is not conducive to slowing down the seedlings.

7. Field management, timely check the seedlings and fill the gaps, and appropriately top the excessively long stems. If the growth is too vigorous after ridge sealing, it can be sprayed with chlormequat or Bijiu solution to control the growth of stems and leaves. For premature senescence fields with yellowing leaves, foliar sprays can be applied with urea 1% or potassium dihydrogen phosphate aqueous solution, and sprayed once every half a month.

8. Turn the seedlings in a timely manner. The sweet potato seedlings covered with plastic film did not take root, which saved a lot of trouble. If there is no mulch covering, after the sweet potato is overgrown on the ground, the seedling should be turned over, and the seedling should be picked up from the ground with a stick, and the adventitious roots of the seedling rooted in the soil should be torn off once in a while.

If you don't turn the seedlings, the sweet potatoes won't grow much.

9. Timely harvesting, the root is not easy to water within 20 days before the root is harvested, so as not to reduce the storage resistance of the root, such as the autumn waterlogging to drain in time, otherwise the sweet potato is not resistant to storage, and there will be "hard heart" rot in serious cases.
