The latest key points of Potato Seedling Management

The period of potato seedling emergence to group plant is the seedling stage, and its seedling stage is relatively short, only about half a month. At this time, the matching period should be short, grow early, grow fast, pay attention to seedling cultivation and lay a high yield foundation. So how to manage the potato seedling stage? Let's take a look.

1. Promoting root

When the seedlings were unearthed, spraying 2116 Zhuangmiaoling + 300x urea solution every 10-15 days for 3-4 times could promote root growth, plant health, drought and low temperature tolerance, promote fertilizer absorption and utilization by plant roots, enhance leaf photosynthetic efficiency, promote nutrient synthesis, and lay a solid foundation for early fruiting and increasing yield.

2. Ploughing and weeding

Weeding in the middle tillage should be done well in the seedling stage, the weeding in the middle tillage should be diligent and early, the resistance of the seedlings is weak after being unearthed, and weeds will affect its normal growth and development, so weeding must be done diligently, and attention should be paid to the concentration and methods of weeding when using chemicals. Mid-tillage can increase soil temperature, loosen soil, break soil consolidation, promote soil gas flow, and promote plant growth.

3. topdressing at the right time

Topdressing should be carried out in the seedling stage and bud stage combined with watering, especially in the early budding stage, when the underground tuber expands rapidly and the potato has the highest demand for fertilizer and water. At this time, topdressing should be combined with watering to dissolve fertilizer and begin to be absorbed by plants. Potassium sulfate compound fertilizer can be applied 20-30 kg per mu, or fertilized according to the application of base fertilizer and seedling growth to promote tuber expansion.

4. Control of underground insect pests

When ladybugs are found to be harmful in the seedling stage, 1500-2000 times cyhalothrin solution should be sprayed in time to control. Underground pests are easy to die when seedlings are encountered, so attention must be paid to underground pest control. 3000-4000 grams of phoxim granules per mu are applied for control.
