Problems solved by technology

However, the nutrient ratio of the existing slow-release compound fertilizers is relatively fixed, it is difficult to meet the different needs of various soils and various crops, and does not match the growth needs of crops, especially the growth of potatoes, thereby reducing fertilizer efficiency and affecting crop growth. Reduce production and income

Abstract

The invention discloses a slow-release fertilizer for planting potatoes. The slow-release fertilizer is characterized by comprising the following raw material components in parts by weight: 40-50 parts of modified peanut shells, 10-15 parts of cow dung, 18-22 parts of green weed manure, 5-8 parts of urtica leaf and stem powder, 2-4 parts of garlic husks, 8-10 parts of urea, 6-8 parts of potassium hydrogen phosphate, 4-6 parts of calcium chloride, 2-3 parts of sodium borate and 7-9 parts of bacterial powder filler. Due to the adoption of the peanut shells, the production cost is reduced, and meanwhile, the phenomenon that the nutrition of the traditional compound fertilizer is single and fixed is relieved; due to the synergistic effect of the green weed manure and the urtica leaf and stem powder, nutrients required by the growth can be provided for the roots of crops, waste materials can be changed into things of value, a healthy growth environment can be provided, the bacterial powder filler has dewatering and water controlling capacity and a good slow-release effect, and viable bacillus subtilis powder also has certain pest expelling and sterilizing effects, so that the nutrients are not easily lost, the fertilizer effect is more long, and both production and income can be favorably increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a slow-release fertilizer used for planting potatoes. Background technique [0002] Potatoes like to be cool and cool, and the formation and growth of underground tubers require 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. [0003] In modern agricultural production, compound fertilizers can be seen everywhere, playing an important role in promoting high and stable crop yields. However, with the application of fertilizers, the diversity of surface plants decreased, and the ecological environment began to deteriorate, followed by a decrease in soil biodiversity, and finally serious soil degradation.
