Microbial mixed fertilizer for lycium barbarum cultivation and preparation method thereof

Abstract

The invention discloses a microbial mixed fertilizer for lycium barbarum cultivation and a preparation method thereof. The microbial mixed fertilizer is prepared from a microbial bacterial fertilizer,a chemical fertilizer and a farmyard manure mixture. The preparation method of the microbial mixed fertilizer mainly comprises the following steps of preparation of farmyard manure, addition of the fertilizers, shed film decomposition and secondary addition of the bacterial fertilizer. The microbial mixed fertilizer is obtained by mixing the microbial bacterial fertilizer, the chemical fertilizerand the farmyard manure mixture according to an appropriate proportion, the best fertilization effect can be achieved in soil of lycium barbarum planting land with high saline-alkaline hardening degree, the utilization rate of the fertilizer reaches 80% or above, and the problems are solved that the utilization rate of the microbial bacterial fertilizer is low due to the excessive alkali contentof the soil, the nutrient content of using the farmyard manure alone is excessively low, and the utilization rate of using the chemical fertilizer alone is excessively low.

Description

technical field [0001] The invention belongs to the technical field of wolfberry planting, and in particular relates to a microbial mixed fertilizer for wolfberry cultivation and a preparation method thereof. Background technique [0002] Fertilizer is an important material basis for agricultural development. For a long time, the excessive application of chemical fertilizers has caused environmental pollution, increased pests and diseases, and the decline in the quality of agricultural products. At the same time, the extensive use of chemical fertilizers has also continuously increased the cost of agricultural production. It has been highly valued by relevant state departments; in recent years, my country has been working hard to explore effective ways to rationally fertilize and improve the utilization rate of chemical fertilizers. The role in agriculture has gradually been recognized by people, and microbial fertilizers have gradually been applied to crop cultivation. [00...

AI Technical Summary

Problems solved by technology

[0003] Most counties, cities, towns and towns in Northwest my country are located on the edge of the Gobi Gobi, and the land has a high degree of saline-alkali compaction. In order to make full use of the unique location and climate advantages of local alkaline land and long sunlight time, we vigorously promote the cultivation of wolfberry that is resistant to salt and alkali and is easy to survive. , but the average pH value of the local wolfberry planting soil has reached 8.3. For microbial fertilizers with a suitable pH value between 7.0-8.0, over-alkaline soil will reduce the use of microbial fertilizers, and microbial fertilizers alone cannot exert their full potential. It should have the desired effect. If chemical fertilizers are used excessively, the local soil compaction will be further aggravated.

[0004] Although there are many varieties of existing microbial fertilizers, most of their fertilizer effects are relatively average in the process of growing wolfberry, mainly because the composition of the existing various microbial fertilizers is not very reasonable enough, and the ratio of each component is not scientific. , thus greatly affecting the performance of fertilizer fertilizer, therefore, there is an urgent need for a microbial mixed fertilizer with good fertilizer efficiency, scientific and reasonable formula combination, environmental protection and harmlessness suitable for wolfberry cultivation
