Fertilizer for planting Lpomoea batatas

Abstract

The invention relates to the field of fertilizers, and especially relates to a fertilizer for planting Lpomoea batatas. The organic fertilizer comprises the following components in parts by weight: 20-25 parts of straw, 10-20 parts of sawdust, 10-12 pats of expanded perlite powder, 1-2 parts of a nitrification inhibitor DMPP, 0.3-0.5 parts of tea saponin, 9-10 parts of urea, 9-11 parts of formaldehyde, 10-12 parts of pig manure, and 4-6 parts of cattle bone powder. The fertilizer overcomes the disadvantages of prior art, the preparation method is simple, and the fertilizer for planting Lpomoea batatas has the advantages of high utilization rate, reduced addition of common fertilizers, and improved nitrogen activity; the fertilizer can activate original nutrients in soil, ensure full absorption and utilization of crops, promote increase of crop yield, improve stress resistance of crops, and effectively improve soil. The fertilizer has good adaptability, and is suitable for most crops and soil with good compatibility, and various fertilizers can be added.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a fertilizer for planting sweet potatoes. Background technique [0002] The fertilizers currently on the market for the application of sweet potatoes are generally aimed at supplementing certain elements or using ordinary chemical fertilizers. In fact, the effective absorption of fertilizers during the planting of sweet potatoes is less than 50%, and the nutritional value of many fertilizers is low. Being wasted, that is to say that the fertilizer utilization rate of general application is very low, so it is also very necessary to be solved urgently about the research on being able to repeatedly release fertilizer to supply the nutrients needed for sweet potato growth. Contents of the invention [0003] In view of the above problems, the technical problem to be solved in the present invention is to provide a fertilizer for planting sweet potatoes. [0004] In order to solve the abov...

[0002] The fertilizers currently on the market for the application of sweet potatoes are generally aimed at supplementing certain elements or using ordinary chemical fertilizers. In fact, the effective absorption of fertilizers during the planting of sweet potatoes is less than 50%, and the nutritional value of many fertilizers is low. Being wasted, that is to say, the utilization rate of commonly used fertilizers is very low, so research on the ability to release fertilizers many times to supply the nutrients needed for sweet potato growth is also very necessary and needs to be resolved urgently
