Abstract

The invention discloses a water retaining fertilizer for potatoes. The fertilizer is prepared from, by weight, 20-30 parts of urea, 20-30 parts of potassium phosphate, 20-30 parts of potassium chloride, 5-8 parts of calcium chloride, 2-4 parts of zinc sulfate, 1-2 parts of potassium borate, 0.5-1 part of copper chloride, 3-4 parts of magnesium sulfate, 1-2 parts of vitamins, 20-40 parts of fermented needle mushroom residues and 5-8 parts of additives, wherein the additives include chitosan, carboxymethyl cellulose, lignite and ammoniated biochar. The invention further discloses a preparing method of the water retaining fertilizer for potatoes. The water retaining fertilizer is good in water retaining property and rich in nutrient and can improve the soil breathability and promote the potato growth.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water-retaining fertilizer for potatoes and a preparation method thereof. Background technique [0002] Potato is the fourth largest food crop in the world and a staple food with important edible value and processing value in China. The crop has a high water requirement and is sensitive to water deficiency, which can hinder or even seriously damage the normal potato development. However, about 60% of the potato planting in China is in arid and semi-arid areas, and there are very few potatoes with irrigation conditions. [0003] People often add water and nutrients to potatoes by mixing water-retaining agent and fertilizer, but the water-retaining agent and fertilizer will reduce the water absorption performance of the water-retaining agent, and even affect the absorption of nutrients by potatoes, hindering the growth of potatoes. Contents of the invention [0004] Based...
