Compound fertilizer for increasing yield of lotus roots

Abstract

The invention discloses a compound fertilizer for increasing the yield of lotus roots. The compound fertilizer is prepared from, by weight, 150-170 parts of organic fertilizers, 0.4-0.8 part of calcium chloride, 0.6-1 part of magnesium sulfate, 2-4 parts of sodium selenite, 1-2 parts of zinc sulfate, 0.4-1.2 parts of diaminoferric xanthohumate, 100-120 parts of major-element fertilizers, and 4-8 parts of fertilizer retaining synergist. A preparing technology of the fertilizer retaining synergist includes the steps that sodium bentonite, isobutyl triethoxysilane and absolute ethyl alcohol are mixed to be even and ultrasonically dispersed, the absolute ethyl alcohol is removed, polyethylene oxide and hydroxypropyl acrylate are added, the mixture is ground to be even, the pH value of the system is adjusted to be 6.4 to 6.8, potassium persulfate and sodium sulfite are added under nitrogen protection, the mixture is stirred to be even, N,N-methylene bisacrylamide is added, the mixture is stirred, filtered, dried and smashed, and the fertilizer retaining synergist is obtained.

Description

technical field

[0001] The invention relates to the technical field of fertilizers, in particular to a compound fertilizer for improving the yield of lotus roots. Background technique

[0002] The taste of lotus root is sweet and sour, and it has many nutritional values. At present, in the planting process, there are often low fruit yields and poor quality phenomena due to improper management, or some growers only determine the type of fertilizer based on general planting experience when fertilizing, or use a large amount of fertilizers to increase yield. Chemical fertilizers and pesticides have caused serious damage to the soil, and the amount of pesticides on the fruit peels exceeds the standard. There are also some improper planting methods, which lead to a low survival rate of lotus roots, seriously damage the planting benefits, and cannot meet the needs of the market.
