Attention should be paid to the management of potato growing period

Apply more fertilizer and water.

During the period from the full flowering period to the senescence of stems and leaves, this period is also the period when the potato needs the most fertilizer and water in its life. Spraying Diguo Zhuangtieling can increase the nutrient flow, promote fruit development and expansion, enhance plant water absorption and fertilizer absorption, and improve fruit yield and quality. And 25 kg of nitrogen, phosphorus and potassium compound fertilizer per mu or about 5 kg of high potassium fertilizer per mu to ensure an adequate supply of water and fertilizer.

Pay attention to the cultivation of soil.

After the potato pieces turn green, the content of solanum nigrum increases, which not only tastes spicy and tastes less commercial, but also has toxic symptoms such as nausea and dizziness, so it is necessary to cultivate soil in time to prevent the above phenomena from happening. Potatoes are generally cultivated twice with a thickness of 3cm to 4cm to prevent potato pieces from exposing the ground.

Control the growth.

The full flowering stage of potato is also the most exuberant stage of aboveground stem and leaf growth. at this stage, we should pay attention to control the vigorous growth and promote the expansion of potato pieces. According to the growth of potato, Chuanhuawang No. 3 can be sprayed to force the top tip to return a large amount of exuberant nutrition, so that its main nutrition can be transferred to the young fruit development system, improve fruit expansion vitality, avoid leaf hypertrophy and improve field permeability.
