Fertilizer for sweet potato planting

Abstract

The invention relates to the field of fertilizers and particularly relates to a fertilizer for sweet potato planting. The fertilizer is prepared from the following ingredients in parts by weight: 20-25 parts of straws, 10-20 parts of sawdust, 10-12 parts of expansible perlite powder, 1-2 parts of nitrification inhibitor DMPP, 0.3-0.5 part of tea saponin, 9-10 parts of urea, 9-11 parts of formaldehyde, 10-12 parts of pig manure and 4-6 parts of bovine bone powder. According to the fertilizer, the disadvantages in the prior art can be overcome, the preparation method is simple, the prepared fertilizer for sweet potato planting is high in utilization ratio, the investment of the conventional fertilizers is reduced, the nitrogen activity is improved, inherent nutrients in soil can be activated, crops can thoroughly absorb and utilize the nutrients, the increase of yield of the crops is promoted, the resistance of the crops is improved, and the soil can be effectively improved; due to high adaptability, the fertilizer is applicable to the majority of crops and soil; and due to good compatibility, 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
