Selenium-enriched biological organic fertilizer and fertilization method thereof

Abstract

The invention discloses selenium-enriched biological organic fertilizer. The selenium-enriched biological organic fertilizer is prepared from raw materials containing organic matters, major elements such as nitrogen, phosphorus and potassium as well as trace elements such as calcium, magnesium, sulfur, silicon, boron, zinc, copper and molybdenum through the processes of pulverizing, mixing, fermenting and the like. The organic fertilizer comprises the following components in percentage by weight based on active content: 40 percent of organic matters, 1.5 to 2.0 percent of nitrogen, 2.5 to 3 percent of phosphorus pentoxide, 1.5 to 3.4 of potassium oxide, 4.25 percent of calcium, 1.85 to 2.0 percent of magnesium, 1.5 percent of silicon, 1.3 percent of boron, 2.4 percent of sulfur, 0.05 percent of copper and 0.02 percent of molybdenum. Basic fertilizer special for production of clonal line selenium-enriched fruits and vegetables contains organic matters, N, P and K which are necessary forfruit and vegetable production soil, also contains calcium, magnesium, boron, iron and sulfur which are specially added, and can enhance the disease resistance, wind, resistance, flooding resistanceand cold resistance of the fruits and vegetables, so that the fruit and vegetable agricultural products are green, organic, rapid in growth, well-balanced in tree shape and high in finished product rate.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a selenium-enriched bio-organic fertilizer and a fertilization method thereof. Background technique [0002] The fruit and vegetable agricultural products grown in South China have excellent characteristics such as short growth period, fast growth, and high yield. In order to obtain a higher yield in a short period of time, a large amount of basal fertilizer must be applied, especially in the south where the soil is poor, and the effect of planting and applying basal fertilizer is very obvious, and it is also one of the important measures for producing green fruits and vegetables. [0003] In the multi-round production of fruit and vegetable growth, sufficient base fertilizer is still the primary material guarantee for production. In areas where there is no understanding of the special base fertilizer for fruits and vegetables, most growers will use imported com...

Problems solved by technology

And use this kind of fertilizer as basal fertilizer or germination fertilizer, because fruits and vegetables have different crops to the demand of organic matter, this has just caused the waste of fertilizer nutrient, has increased cost, and because of lacking the necessary middle trace element (ca
