Biological fertilizer improving soil

Abstract

A disclosed biological fertilizer improving soil is characterized by comprising the following substances in parts by weight: 200-250 parts of paddy rice straw, 120-130 parts of chicken manure, 150-170 parts of pig manure, 50-60 parts of rice bran, 1-3 parts of trace elements, 3-7 parts of potassium polymetaphosphate, 2-9 parts of potassium pyrophosphate, 13-20 parts of sodium aluminum phosphate, 1-6 parts of calcium hydrogen phosphate, 11-18 parts of calcium phosphate, 25-30 parts of calcium pyrophosphate, 0.1-0.2 part of rhodococcus powder, 0.1-0.2 part of pityrosporion ovale powder, and 0.1-0.2 part of humic acid. The biological fertilizer is non-toxic, harmless and free of pollution, is capable of comprehensively providing nitrogen, phosphorus and potassium for crops, does not cake soil, is capable of improving soil structure, has relatively strong water retention capability, and has relatively excellent effect and relatively long fertilizer efficiency especially aiming at dry crops.

Description

technical field [0001] The invention relates to a biological fertilizer for improving soil. Background technique [0002] In the prior art, the development from farmyard manure to chemical fertilizer, the application of chemical fertilizer has led to a rapid development of agricultural production, but chemical fertilizer pollutes the environment, compacts the soil, destroys the soil structure, and makes many beneficial organisms in the soil gradually extinct, resulting in the decline of soil fertility , Deterioration of crop quality and other defects. In addition, the application of organic fertilizers on the soil where chemical fertilizers have been applied, due to the lack of decomposition of beneficial microorganisms, the nutrients in them cannot be released for absorption and utilization by crops, so the fertilizer and absorption rate are low, and the fertilizer efficiency is poor. To improve soil fertility, we have to use increase The application of chemical fertilizer...

Problems solved by technology

[0002] In the prior art, the development from farmyard manure to chemical fertilizer, the application of chemical fertilizer has led to a rapid development of agricultural production, but chemical fertilizer pollutes the environment, compacts the soil, destroys the soil structure, and makes many beneficial organisms in the soil gradually extinct, resulting in the decline of soil fertility , crop quality deterioration and other defects

In addition, the application of organic fertilizers on the soil where chemical fertilizers have been applied, due to the lack of decomposition of beneficial microorganisms, the nutrients in them cannot be released for absorption and utilization by crops, so the fertilizer and absorption rate are low, and the fertilizer efficiency is poor. To improve soil fertility, we have to use increase The application of chemical fertilizers, if things go on like this, will inevitably aggravate soil compaction on the one hand, destroy the structure of soil aggregates, and make the soil fertility decline, and on the other hand, increase the investment in agriculture year by year
