Seedling raising substrate for promoting absorption of chilies to phosphorus and preparation method thereof

Abstract

The invention discloses a seedling raising substrate for promoting absorption of chilies to phosphorus and a preparation method thereof. The seedling raising substrate comprises a basic material, andthe basic material is composed of grass carbon, vermiculite and perlite and further comprises a nitrogen-phosphorus-potassium substrate and a phosphate-solubilizing bacterium solution, wherein 3-8 g of the nitrogen-phosphorus-potassium substrate and 100-150 ml of the phosphate-solubilizing bacterium solution are added into each kilogram of the basic material. The preparation method comprises the following steps of strain activating, preparing of the nitrogen-phosphorus-potassium substrate, preparing of the basic material and preparing of the seedling raising substrate. Through the chili substrate, absorption of the chilies to phosphorus is significantly promoted, and technical support is provided for decreasing the use amount of chemical fertilizer.

Description

technical field [0001] The invention relates to the technical field of seedling-raising substrates, in particular to a seedling-raising substrate for promoting the absorption of phosphorus by peppers and a preparation method thereof. Background technique [0002] Pepper is widely planted in my country and is an important economic crop of characteristic vegetables. Along with the scale, standardization and specialization of pepper production in our country, pepper seedling cultivation in industrial plug trays has developed rapidly, so the demand for pepper-specific seedling substrates continues to increase; moreover, a good seedling substrate can provide a stable and coordinated environment for the growth of vegetable seedlings. Water, fertilizer, air, heat and other conditions, have the functions of fixing and supporting vegetable plants, supplying water and nutrients, loosening and ventilating. Pepper seedlings have a relatively long cycle. Although after the seeds germina...

AI Technical Summary

Problems solved by technology

[0003] At present, the seedling substrate of pepper is mainly composed of peat, vermiculite, perlite, etc. according to a certain proportion. However, these components lack nutrients such as nitrogen, phosphorus, and potassium, and are not suitable for vegetable crops with a long seedling cycle; Potassium is the main nutrient absorbed by the growth and development of seedlings. The lack of nitrogen, phosphorus and potassium in plants will result in reduced yield, short plants, and easy lodging.

Among them, phosphorus is an important nutrient in plant growth. The fixation of phosphorus in the soil and substrate leads to a low utilization rate of phosphorus fertilizer, which endangers the growth of plants.
