Total nutrient rice seedling culture substrate

Abstract

The invention provides a total nutrient rice seedling culture substrate, belonging to plant seedling culture substrates in the field of agriculture, and in particular relates to a total nutrient rice seedling culture substrate which takes turf as a main ingredient. The total nutrient rice seedling culture substrate contains 70%-87% of turf, 10%-27% of a fertilizer and 3%-15% of an agricultural water-retaining agent by weight percentage, wherein the fertilizer contains 20-40 parts of a nitrogen fertilizer, 15-25 parts of a phosphate fertilizer, 10-15 parts of a potash fertilizer, 8-12 parts of hypha protein powder, 6-10 parts of fulvic acid and 5-10 parts of fly ash in parts by weight. The total nutrient rice seedling culture substrate provided by the invention has the advantages of warming, ventilating, retaining the fertilizers and water, being nutritionally balanced, small in volume weight, easy and convenient to operate, easy to manage, good in seedling quality and low in seedling culture cost, labor and effort conservation, and the like.

Description

technical field [0001] The invention belongs to a plant seedling-raising substrate in the agricultural field, in particular to a full-nutrient rice seedling-raising substrate with peat as the main component. Background technique [0002] my country's rice seedling cultivation still follows the traditional method of borrowing soil to raise seedlings. This method has the following shortcomings: First, the traditional soil seedling raising process is complicated, labor-intensive, high cost of seedling raising, low technical content, and difficult to manage. The preparation of nutrient soil only includes many processes such as borrowing soil, drying soil, crushing, sieving soil, mixing fertilizer, mixing medicine, adjusting acid, weeding, and preventing diseases. ), the field transportation of seedlings is labor-intensive, while the rice seedling substrate of the present invention is only about 4 catties per plate, and the seedling transportation intensity is greatly reduced.

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: First, the traditional soil seedling breeding process is complicated, labor-intensive, high seedling cost, low technical content, and difficult to manage

Second, it is difficult to guarantee the quality of seedlings raised in traditional soil

Due to the serious soil-borne diseases of soil seedlings, the requirements for sowing management are high; in case of low temperature in spring, physiological diseases often occur, the quality of seedlings is poor, and it is difficult to grow high-quality robust seedlings; It is very difficult; the success rate of seedling cultivation is low, which is not conducive to factory and standardized seedling cultivation

Third, it is difficult for farmers to raise seedlings and obtain soil

Some farmers go to various places to buy soil; they even dig out the ridges of the paddy fields that they have worked so hard to use as soil for rice seedlings.

Fourth, there has been a serious conflict between raising seedlings and taking soil and protecting the ecological environment

In recent years, people have been exploring and reforming the traditional soil seedling raising methods, and some rice seedling raising substrates have been newly invented, mainly using crop straw fermentation, rice husk fermentation, waste edible fungus bag fermentation, perlite, pulp mixture, and perlite + leech The mixture of stone + peat as raw materials has restricted the progress of new substrates and new technologies for seedlings due to complex production processes, inconvenient transportation of raw materials, high production costs, difficult operations, limited resources, and unsatisfactory seedling effects. Difficult to popularize and apply in a large area, and difficult to innovate and make substantial technical breakthroughs in traditional soil seedling cultivation methods
