However, many growers have found that potatoes only grow but do not produce potatoes or produce few potatoes.

Potato is a common vegetable, which is planted in many areas. in the process of planting, the general flowering of potato represents the stage of reproductive growth, which is also the stage of potato fruiting. However, many growers have found that potatoes grow only but do not produce potatoes or produce few potatoes. What is the reason for this? How to prevent it? Let's take a look.

First, the reason why potatoes do not produce potatoes or there are few potatoes.

1. The temperature is too high

The suitable temperature for potato tuber formation is 19-22 degrees during the day and 13-15 degrees at night. When the temperature is higher than 25 degrees, the tubers will stop growing, but the stems and leaves will grow vigorously, so when planting potatoes late sowing or suddenly encounter high temperature weather, there will be little or no tuber.

2. Sowing too late

Potato can be planted in all seasons, generally in spring, autumn and winter. If high temperature occurs in tuber formation, it means that it is too late to sow seeds, and it is easy to encounter rainy season and high temperature season, which is not conducive to tuber formation.

3. Variety

Different varieties of potato have different sensitivity to light and temperature, and spring and autumn are suitable for potato growth for a short time, so when planting mid-and late-maturing varieties, there will be no tuber phenomenon.

4. Improper cultivation and management

For example, sowing too densely, fertilizing too much nitrogen fertilizer, and insufficient phosphorus and potassium fertilizer, will lead to excessive growth of seedlings, resulting in poor permeability, which is not conducive to the formation of tubers.

5. Drought

Potato is sensitive to water, and the soil should be kept moist during tuber formation and growth period. if it is too dry, it is difficult to form tuber, so it should be irrigated in time when drought occurs during tuber formation and growth period.

6. Sowing is too shallow

The sowing depth of potatoes is generally 15-20 cm. Sowing too shallow will lead to high ground temperature, and it is easy to take root at will, so in the potato period, we should cultivate the soil at the right time, the soil is too shallow, the soil temperature changes greatly, and the effect of heat preservation is small, which will affect the formation and expansion of tubers.

II. Preventive measures

1. Variety selection

The selection focuses on the selection of varieties with high yield and high individual weight, as well as the local climate and soil conditions.

2. Appropriate early sowing

Should potatoes be planted in December-January in winter? too early and too late are not conducive to listing. Spring potatoes should be cultivated with plastic film mulching and sown in January-February.

3. Cultivation and management

It is suggested that the reasonable sowing density and depth should be no more than 4000 trees per mu, and the sowing depth should be controlled at about 15-20 cm. Attention should be paid to the application of organic fertilizer and magnesium fertilizer, and little or no nitrogen fertilizer should be applied in the middle and later stage, so as to avoid excessive plant growth and affect the growth of tubers.

4. Rational watering

In the potato growing period to keep the soil dry and wet is suitable, found that the humidity is low is to immediately irrigation, to achieve frequent irrigation of small water, in case of rainy weather to timely drainage.

The above is the introduction of the reasons for little or no potato formation and preventive measures. I hope it can help you. If you want to know more about it, please follow us.
