Organic set meal seedling-raising nutrient medium and preparation method thereof

Abstract

The invention provides an organic set meal seedling-raising nutrient medium and a preparation method thereof. The nutrient medium consists of a germination period substrate, a seedling period substrate and a seedling formation period substrate. The organic set meal seedling-raising nutrient medium suitable for the growth of raised plant seedlings in a germination period, a seedling period and a seedling formation period is prepared by scientifically and reasonably matching a natural organic matter serving as a carrier, an organic substrate, an inorganic substrate and various nutrient elementsfor preventing the disease and pest of the raised seedlings through a scientific process according to the requirements of nursery stock in different growth periods on nutrients based on a plant nutrient theory.

Description

technical field [0001] The invention relates to an organic package seedling-raising nutrient base and a preparation method thereof, and more particularly relates to an organic package seedling-raising nutrient base for plants (arbors), planting forests on deserts, Gobi, steep slopes, and vegetable seedlings. Background technique [0002] my country's chemical fertilizer consumption accounts for about 20-30% of the world's total chemical fertilizer consumption, ranking first in the world. The average seasonal utilization rate of chemical fertilizers in developed countries is 50-60%, while the average seasonal utilization rate of chemical fertilizers in my country is only 30-35% %. The loss and waste of a large number of nutrients not only bring huge economic losses to the society, but also cause serious environmental pollution. It is particularly important to improve the utilization rate of fertilizers, reduce the amount of fertilization, and save labor for fertilization. ...

Problems solved by technology

[0003] Over the years, the application of chemical fertilizers on crops has played a huge role in increasing crop production, but due to a large amount of unreasonable use of chemical fertilizers, it has caused soil compaction, soil fertility decline, environmental pollution, ecological damage, especially the decline in the quality of agricultural and sideline products

In recent years, although various compound ecological fertilizers have appeared, which have achieved certain effects in improving the quality of agricultural and sideline products and preventing soil compaction, the organic raw materials used are mainly industrial organic wastes decomposed by microorganisms, The main defects of crop stalks, livestock and poultry manure, etc.: First, the nutrients in the inorganic fertilizers used are mostly in a locked state, lack of degradation and activation, and are difficult for crops to absorb, which not only causes waste of fertilizers, but also leads to soil structure degradation, hardening, water and fertilizer Decrease in ability to maintain and resist drought and flood and destruction of ecological environment

The third is to pay more attention to the supply of large, medium and trace elements, but lack of degradation, activation and nourishment of organic components. In addition, harmful substances and pesticide components are carried in the products, resulting in a decline in the quality of agricultural products, low nutritional value, and lack of ecological crops. sweet and savory taste
