Straw fertilizer for improving continuous cucumber cropping soil

Abstract

The invention belongs to the technical field of soil remediation and in particular relates to a straw fertilizer for improving continuous cucumber cropping soil. The straw fertilizer is prepared by fermenting crop straws, cyperus rotundus rotten roots, carbonized rapeseed pods, boron-magnesia fertilizers, monopotassium phosphate, dipotassium phosphate, actinomycetes, root rot bacteria and verticillium dahliae. Compared with the prior art, the straw fertilizer disclosed by the invention has the advantages that by analyzing the loss problem of the continuous cucumber cropping soil and selection and reasonable proportioning of raw materials in the formula and by fermenting the raw materials, the obtained fertilizer is capable of improving the microbial environment and the composition change of the continuous cucumber cropping soil, heavy metals in the soil can be adsorbed according to organic combination of biological and vegetal characteristics of cucumber and inorganic trace elements, the absorption of crops on the heavy metals can be reduced, losses of nutritional ingredients in the soil are reduced, and problems occurring during continuous cucumber cropping are solved, so that the yield and the quality can be prevented from being influenced after continuous cropping, and economic benefits are obvious.

Description

Technical field [0001] The invention belongs to the technical field of soil remediation, and specifically relates to a straw fertilization for improving cucumber continuous cropping soil. Background technique [0002] Nowadays, vegetable facility cultivation is a fast-growing industry in facility agriculture and has become an important part of modern agriculture. However, due to the large cultivation area and large market demand for products, continuous cropping is very common, and continuous cropping obstacles are very serious, which directly leads to vegetables. With the sharp decline in product and quality, continuous cropping obstacles have become one of the restricting factors for the sustainable development of facility vegetable production. The continuous cropping obstacles with soil-borne diseases as the main feature have always been mainly based on chemical agents, which not only have side effects. , And it is easy to cause environmental pollution.

[0002] Today, protected cultivation of vegetables is a fast-growing industry in protected agriculture and has become an important part of modern agriculture. However, due to the large cultivation area and the large amount of products demanded by the market, continuous cropping is very common and the obstacles to continuous cropping are very serious, which directly leads to vegetable cultivation. With the sharp decline in products and quality, continuous cropping obstacles have become one of the restrictive factors for the sustainable development of facility vegetable production. The continuous cropping obstacles characterized by soil-borne diseases have always been controlled by chemical agents, which not only have side effects , and it is easy to cause environmental pollution. Although it can reduce the occurrence of continuous cropping diseases, its use is limited due to its strong toxicity and serious harm to human health and the environment. In addition, crop straw is the main by-product in the production process. Large, and there is no ecological and economical and effective recycling method. Even if the straw is composted or directly poured into the field, the natural degradation time of the straw is long, and the conversion efficiency is not ideal, which affects the application of subsequent crops. The limitation of composting conditions leads to the need to Covering a large amount of soil will easily destroy precious soil resources and cannot improve the soil structure. Therefore, further research on how to effectively use straw
