Tobacco complete-nutrition integrated base-topdressing fertilizer and preparation method thereof

Abstract

The invention discloses tobacco complete-nutrition integrated base-topdressing fertilizer, comprising the effective components, including, by weight, 20-30% of active biological bacterial fertilizer, 2-5% of medium-trace element fertilizer, and 65-75% of an inorganic fertilizer, wherein the active biological bacterial fertilizer is made from, by weight, 50-60% of rapeseed meal, 20-30% of soybean meal, 5-10% of sesame seed meal, 5-10% of peanut meal and 1-2% of EM (effective microorganism) composite bacterial agent by means of full fertilization and decomposition through trough-type mechanical aeration fermentation. The tobacco complete-nutrition integrated base-topdressing fertilizer replaces conventional base fertilizer, special topdressing, potassium sulfate and other fertilizers; nutrients of the various fertilizers are retained; by adding the slow-release fertilizer ingredient into the tobacco complete-nutrition integrated base-topdressing fertilizer, the growth need of tobacco during growth can be met just through single fertilization, fertilization labor and cost are reduced, the input-output ratio is increased, and the income of tobacco farmers is increased.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a flue-cured tobacco full nutrient-based topdressing integrated fertilizer and a preparation method thereof. Background technique [0002] The construction of modern flue-cured tobacco agriculture is inseparable from the progress of science and technology. Its basic characteristics are intensive saving, informatization, specialization and scale. Establishing and improving the light and simple cultivation technology system will be the main direction of the development of modern flue-cured tobacco agriculture in the future. In recent years, although the investment in flue-cured tobacco production has gradually increased, the phenomenon of increasing production without increasing efficiency has become more and more common. The main reason is that the number and quality of rural laborers have generally declined, the number of tobacco growers has decreased, the average planting ...

AI Technical Summary

Problems solved by technology

It can be said that problems such as excessive labor and high cost have always been the bottleneck restricting the large-scale production of tobacco leaves

With the rapid expansion of the average household size and the continuous increase of labor costs, the cost of flue-cured tobacco cultivation has increased significantly

Taking the traditional flue-cured tobacco package fertilization technology as an example, its fertilization mode is base fertilizer + seedling raising fertilizer + special topdressing fertilizer + potassium sulfate, in which the base fertilizer includes organic fertilizer and compound fertilizer for 2 times of fertilization, the seedling raising fertilizer is applied in 2 times, and the special topdressing fertilizer is 2 times. -3 times, potassium sulfate topdressing 1-2 times, so in terms of fertilization, huge labor fertilizer costs and fertilization labor costs will seriously restrict the development of modern tobacco leaves
