Is it better to sow potatoes flat or on ridges?

Planting potatoes should be planted on sandy soil, flat terrain, drought watering, and waterlogging drainage. The requirements for the soil are to strive for fertility and looseness. As for how to sow seeds, here are a few suggestions:

First of all, it is necessary to sow seeds at the right time. Sowing at the right time has an important impact on the growth and development of plants and the formation of yield, which is the key to promote early maturity. There are several principles for determining the sowing date.

First of all, frost should be avoided when potato seedlings are sown in spring, therefore, according to the local final frost date, 20 to 30 days before the appropriate sowing period (germination, mulching and seedling emergence are fast, and appropriate late sowing). Secondly, the tuber formation period should be arranged in the season suitable for tuber formation and expansion. During this period, the average temperature does not exceed 23 degrees, the sunshine hours do not exceed 14 hours, and there is a moderate amount of rainfall.

Thirdly, through facility cultivation, the sowing date range can be appropriately adjusted in order to obtain higher yield and higher economic benefits. Nationwide, potatoes are sown all year round. In each locality, the sowing date must be strictly controlled according to the local climatic conditions.

Then it is time to choose the right way to sow seeds. Potatoes are cultivated crops, and the tubers are formed by expanding underground, so they are suitable for ridge cultivation. For arid sandy soil areas, flat sowing can be used for spring moisture preservation.

Ridge cropping can improve ground temperature, prevent waterlogging, facilitate weeding and soil cultivation, facilitate gas exchange in the soil, and provide good environmental conditions for tuber expansion. The sowing techniques of ridge cultivation have their own characteristics in different places, and they can be roughly divided into three types

Sowing on the ridge: The method of sowing on the ridge is to plant in a ditch, and then build the soil into a ridge, and the thickness of the cover soil is about 10 cm. In some areas, potato pieces are sown on the surface of the soil, and the soil is covered into ridges, because the covering soil is thinner and the soil temperature is higher, the seedlings emerge earlier after planting, and the seedlings are full and strong, but they are not drought resistant.

Ridge cropping is suitable for areas with more rain and more moisture.

In some areas, cultivation is to ridge first, ditch and sow on the ridge, cover the soil after sowing to suppress and protect moisture, and the seed potatoes are above the ground, this method is commonly used in rainy and flood-prone areas, and can be drained in case of waterlogging, and watering is not flooded. Furrow sowing: furrow height 20 30 cm, furrow width 200 cm, furrow surface transverse sowing, general row spacing 35 40 cm, plant spacing about 25 cm.

The height and width of the furrow are determined by the topography and the loose viscosity of the soil, and the covering soil is flat with the furrow surface after sowing.

Flat sowing and sowing: there are two ways to sow and ridge with seedling. Flat cropping is mostly used in areas with high temperatures, low rainfall, drought and lack of irrigation conditions.

The sowing furrow with the ridge can be shallow, and the ridge covering soil should not be thick. After the emergence of ridges, the sowing furrow is generally 10 15 cm deep, and after the emergence of seedlings, combined with the first tillage ridge. When sowing, the ditch is first opened, the cut pieces are placed in the ditch, and then the ditch is flattened.

Finally, there is the sowing density. The appropriate planting density of potatoes depends on the time and conditions, and is also affected by the sowing method and variety. Spring potatoes are thinner than summer and autumn potatoes, and they are also thinner than summer and winter potatoes.

The medium and late maturing large seedling varieties are rarer than the small seedling varieties. The land should be thin when it is good, and dense when it is barren. Planting experts with high management level generally have a sparse cultivation density, a sown whole potato sown, and a large potato sowing sparse than a cut plant.

It is better to grow potatoes with ridges.

Potato ridge planting is better, so it is easy to manage, the yield is high, and the ridge planting effect is better than that of flat planting, but it is more labor-intensive. Personally, I feel that the ridge is made, which is convenient for field management, ventilation and light transmission, and is conducive to mechanical harvesting.

Flat sowing of potatoes is not as good as sowing on ridges, because sowning on Gong is conducive to good ventilation, but the distance between seedlings must be maintained.

Potatoes are still sown on ridges, and they should be sown on large ridges and deeply.

Sowing seeds on the ridges well can make the potatoes grow more and bigger.

The ridge planting soil is loose, which is conducive to tuber expansion.

Ridge sowing is more productive, because ridge sowing can effectively prevent pests and bacteria, so that potatoes are not easy to be made by these things, and now many potato planters also use ridge sowing.

Ridge seeding yields are higher. Ridge forming and high-yield planting is a potato comprehensive planting method that is assembled and integrated with subsoiling, ridge shaping, deep fertilization and reasonable dense planting, which increases the yield by more than 15% and the commodity rate of qualified potatoes by more than 20% compared with the general planting.

Potato is a crop with a large planting area in China, and it is also a favorite food crop of people. There are two types of sowing methods: ridge cropping and flat cropping. Then I will elaborate on their sowing methods and advantages and disadvantages.

Potato stems swell underground, making them more suitable for ridge cultivation. Because ridge cultivation can increase ground temperature and promote early maturation of potatoes, although this sowing method is not drought resistant, it can prevent waterlogging. Moreover, ridge cropping is convenient for weeding, and is also conducive to concentrated fertilization and watering irrigation.

Because the ridge body is higher than the ground, it is conducive to gas exchange, which provides better environmental conditions for the expansion of tubers after tillage. Increase the amount of organic fertilizer, increase the density, and increase the yield.
