Preparation method of flower and plant nutrient soil

Abstract

The invention discloses a preparation method of flower and plant nutrient soil. The flower and plant nutrient soil is prepared from the following ingredients in parts by weight: 50-100 parts of soil, 20-30 parts of vermiculite, 10-15 parts of chicken manure, 10-15 parts of tomato pomace, 8-10 parts of monopotassium phosphate, 5-8 parts of dipotassium phosphate, 5-7 parts of corn flour, 5-10 parts of potassium feldspar powder, 5-10 parts of oyster shell, 3-5 parts of mixed culture, 4-6 parts of glucose and 4-7 parts of water. The nutrient soil prepared by the preparation method has rich nutrition, nutrition substances can be easily adsorbed by plants, the nutrition substances can be prevented from being washed away by rain or from being decomposed under a natural condition, and the nutrition substances can be provided for the plants for a long time.

Description

technical field [0001] The invention relates to the field of flower nutrition soil, in particular to a preparation method of flower nutrition soil. Background technique [0002] China is a country with serious soil degradation. The organic matter content of cultivated land in China is generally low, and the soil organic matter content of paddy fields is mostly 1% to 3%, while the organic matter content of dry land soil is lower than that of paddy fields, and the organic matter content of <1% accounts for 31.2%; most of China The total nitrogen in the cultivated land soil is below 0.2%. Among them, five provinces (regions) including Shandong, Hebei, Henan, Shanxi and Xinjiang account for more than half of the total cultivated land area; the area of ​​phosphorus-deficient soil is 673,000 square kilometers. More than half of the cultivated land in more than 20 provinces (regions) is severely deficient in phosphorus; the proportion of potassium-deficient soil is relatively sm...

The evaluation of the national comprehensive soil fertility status has not been reported yet. As far as the eastern red soil hilly area is concerned, the selection of soil organic matter, total nitrogen, total phosphorus, available phosphorus, total potassium, available potassium, pH value, CEC, physical clay content, The results of the comprehensive evaluation of soil fertility on 11 soil fertility indicators such as powder/clay ratio and surface soil thickness show that most of the soils are affected by fertility degradation to varying degrees, and are in the middle an
