Selenium-rich EM-inoculant-fermenting composite fertilizer for seedless grapes

Abstract

The invention relates to a fertilizer and particularly relates to a selenium-rich EM-inoculant-fermenting composite fertilizer for seedless grapes and a preparation method thereof. The selenium-rich EM-inoculant-fermenting composite fertilizer is prepared from the following materials in parts by weight: 100-120 parts of cow and sheep dung, 40-45 parts of urea, 20-23 parts of potassium chloride, 30-34 parts of calcium superphosphate, 2-3 parts of zinc sulfate, 30-34 parts of vinegar residue, 30-34 parts of manioc waste, 18-20 parts of potassium sulfate, 30-34 parts of ammonium chloride, 2-3 parts of sodium selenite, 3-4 parts of zinc sulfate, 3-4 parts of EM inoculant and 4-6 parts of enveloping agent. The selenium-rich EM-inoculant-fermenting composite fertilizer for seedless grapes and the preparation method have the advantages that since the EM inoculant is utilized for fermenting low-cost materials such as cow and sheep dung, the vinegar residue and the manioc waste and the like, the traditional compost fermenting time is shortened, the fermented and decayed organic fertilizer is matched with a proper amount of chemical fertilizer, so that the nutrition is comprehensive and balanced, not only the yield of the seedless grapes is increased, but also the sweetness is also increased; in addition, due to containing of selenium-rich materials, the edible value of grapes is improved; and the selenium-rich EM-inoculant-fermenting composite fertilizer is environment-friendly and high-efficiency and has less harm to soil.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a compound fertilizer fermented with a selenium-enriched EM bacterial agent for seedless grapes and a preparation method thereof. Background technique [0002] In the process of fruit tree cultivation, the correct selection and application of fertilizers is very important. At present, the fertilizers used for crops are mainly chemical fertilizers. The application of chemical fertilizers is simple, the content of nutrient elements is sufficient, and the absorption is fast. However, long-term use of chemical fertilizers will cause damage to the environment and soil. Irreversible damage, the yield and quality of fruits are gradually declining. In order to improve the sustainable development ability of the soil, organic fertilizers can be used to replace some chemical fertilizers. Combining organic fertilizers and chemical fertilizers, the two can maximize their strengths and avoid weaknesses. The comp...

[0002] In the process of fruit tree cultivation, the correct selection and application of fertilizers is very important. At present, the fertilizers used for crops are mainly chemical fertilizers. The application of chemical fertilizers is simple, the content of nutrient elements is sufficient, and the absorption is fast. However, long-term use of chemical fertilizers will cause damage to the environment and soil. Irreversible damage, the yield and quality of fruits are gradually declining. In order to improve the sustainable development ability of the soil, organic fertilizers can be used to replace some chemical fertilizers. Combining organic fertilizers and chemical fertilizers, the two maximize their strengths and avoid weaknesses. Compound fertilizers are more comprehensive in nutrition and fertilizer efficiency. It is more durable, not only meets the nutrition needed for the growth of fru
