The best time to grow potatoes in the spring is usually when temperatures are stable at 7-10°c, the soil is unfrozen and humid, and generally selected for mid-march to early april. Choosing the right time to grow ensures that the potato germinates and grows well and avoids bad or bad growth due to cold or wet overhang。
1. Temperature conditions: potatoes are suitable for growth in a mild climate, too low temperatures slow the germinate and too high may lead to the decomposition of potatoes. When spring temperatures return to 7-10 degrees celsius, soil temperatures are gradually reaching a suitable range for cultivation. Cultivation can be selected by observing local weather forecasts for several days at a stable temperature。
Soil moisture: potato cultivation requires that the soil be moderately humid but not humid. Overwet soil causes the cultivation of potatoes to rot and affects the gestation rate. Before planting, soil moisture can be checked and a piece of soil can be squeezed by hand, indicating the appropriate humidity if it can be formed without dripping water. If the soil is too wet, it can be properly dried or drained for planting。
3. Potato processing: choose healthy and disease-free seeding, and cut to ensure at least one bud in each piece. The cutting resulted in the drying of potatoes for 1-2 days in the ventilation area, which contributed to healing wounds and reduced the risk of decay. It is also possible to prevent bacterial infections by rubbing grass ash or polybacterium after cutting。
4. Cultivation methods: potato cultivation is generally 8-10 cm, with a range of 60-70 cm and a range of 25-30 cm. Cultivation can be done with the seeding of potatoes and light cover of the soil. After planting, water is properly poured and the soil is humid but water is avoided。
5. Fertilizer management: potato growth requires adequate nutrients, which can be used in soil before planting, either as rotting organic or compound fertilizers. During growth, depending on the growth of potatoes, potassium and phosphorous fertilizers are duly applied to promote tubing. Excessive application of nitrogen fertilizer is avoided in order to prevent long-growing plants from affecting yields。
The key to the cultivation of potatoes in the spring is the selection of suitable temperatures and soil conditions, the rational handling of seeding of potatoes, the application of scientific methods of cultivation and the strengthening of fertilizer management. Through these measures, the production and quality of potatoes can be effectively improved and successful cultivation ensured. Close attention needs to be paid to weather changes and soil conditions during planting, and management measures need to be adjusted in a timely manner to create optimal conditions for potato growth。
