Special fertilizer for potatoes

Abstract

The invention relates to a special fertilizer for potatoes. The special fertilizer comprises the following raw materials: 22-30 parts of wormcast, 3-5 parts of phosphate diamine, 0.5-0.8 part of boric acid, 15-22 parts of pig manure, 3-5 parts of folium argyeiae acutae, 9-12 parts of elm bark, 6-9 parts of radix rubiae, 3-6 parts of artemisia apiacea, 2-6 parts of viscum articulatum, 0.5-1 part of EM microbial strain, 2-3 parts of sulphur, 9-15 parts of wormcast and 0.5-1 part of ammonium molybdate. The special fertilizer for potatoes provided by the invention can reduce the fertilizer application dose and can further reduce the insect damage occurrence rate.

Description

technical field [0001] The invention belongs to the field of chemical fertilizers, and in particular relates to a special fertilizer for potatoes. Background technique [0002] Potatoes are cool and cool, and they are crops that like low temperatures. The formation and growth of its underground tubers requires a loose, airy, cool and moist soil environment. Requirements for temperature: The optimum temperature for tuber growth is 16°C~18°C. When the local temperature is higher than 25°C, the tuber will stop growing; the optimum temperature for stem and leaf growth is 15°C~25°C, and it will stop growing if it exceeds 39°C. Potatoes have always been an important food crop. They are widely planted in our country. Potato fruits are part of the underground stems. During the planting process, pests such as cutworms and mole crickets will eat the underground stems of potatoes, resulting in a reduction in potato production.

Potatoes have always been an important food crop. They are widely planted in our country. Potato fruits are part of the underground stems. During the planting process, pests such as cutworms and mole crickets will eat the underground stems of potatoes, resulting in a reduction in potato production. Now it is often used to add trichlorfon to the planting soil. Waiting for pesticides for treatment, but the use of pesticides not only kills insects, but also causes damage to microorganisms in the soil, resulting in a decrease in soil fertility
