Do I need to water sweet potatoes? When is the best time to dig the ridges?

Sweet potatoes are rich in nutrients and are a food on many people's tables. Sweet potatoes are also easy to grow and are produced in most parts of my country. So do you need to water sweet potatoes? When is the right time to make ridges?

Do I need to water sweet potatoes?

Need to water.

Sweet potatoes like water relatively, but do not like waterlogging. Watering should be done frequently during the seedling stage, and the soil moisture should be kept above 60%. During the expansion period, watering and draining should be done frequently to maintain soil moisture, but waterlogging should not occur. Too much drought will affect the expansion of sweet potatoes, and it is easy to grow firewood roots. Uneven dryness and wetness often cause cracked skin and deformities. Therefore, scientific field management is very important for planting sweet potatoes.

In addition, sweet potatoes like light. If there is sufficient light, the leaves are dark green, the stems are strong, and the conductive tissue of the stems is well developed, it is easy to transport nutrients to various tissues and achieve high yield.

When is the best time to plant sweet potatoes?

Sweet potatoes are tuber crops that require deep, loose, permeable and fertile soil to ensure high yields. Obviously, sweet potatoes are best planted in ridges and ridges, as this is most suitable for the expansion and growth of its underground parts. When ridges and ridges are formed, wide ridges with double rows or narrow ridges with single rows can be used according to the variety or space.

There are many benefits to planting sweet potatoes in ridges. First, it fully utilizes the looseness and air permeability of the soil, which facilitates the expansion of the tuberous stems of the sweet potatoes in the later stage and increases the yield of sweet potatoes. After ridges are formed, it is easy for the sweet potatoes to take deep roots, which means that the role of base fertilizer is fully utilized to improve fertilizer efficiency and better promote the growth of sweet potatoes. It is convenient for drainage to avoid sweet potato rot caused by soaking.

As for when to form ridges, it depends on the season and whether the sweet potatoes are planted in succession.

Sweet potatoes planted in spring are spring sweet potatoes, also called early sweet potatoes, also called white stubble sweet potato planting, that is, planting sweet potatoes on white land. If sweet potatoes are planted on such land, ridges will definitely produce high yields. We all know that spring rain is as precious as oil. In this case, there is little rain, and ridges are planted to facilitate irrigation.

If sweet potatoes are planted after wheat is harvested, they are also called autumn sweet potatoes or successive sweet potatoes. If sweet potatoes are planted under such circumstances, the yield of sweet potatoes will definitely decrease.

Steps for growing pollution-free sweet potatoes:

1. Land preparation requirements.

Clearing weeds on the ground, leveling the land, deep plowing to loosen the soil, improving soil aeration, increasing rainwater infiltration, expanding root distribution, improving drought resistance, and promoting microbial activity are the primary conditions for high yields of pollution-free sweet potatoes.

2. Fertilization requirements.

The principle is "mainly farmyard manure, secondly biological organic fertilizer, and supplemented by chemical fertilizer." About 4,000 kilograms of farmyard manure, 40 kilograms of organic fertilizer, and 30 kilograms of three 17 potassium sulfate compound fertilizer are used per mu.

3. Field management requirements.

Farmyard manure and chemical fertilizer are spread as base fertilizer at one time, which is convenient and saves trouble. It is required to cover the ground with mulch and plant in ridges to increase the yield. In the later stage, foliar fertilizers such as potassium dihydrogen phosphate can be sprayed on the leaves. For insect pests, pyrethroid biological pesticides can be used.
