Paddy seedling cultivation matrix and preparation method thereof

Abstract

The invention discloses a rice seedling raising substrate, which is characterized in that it is composed of the following components according to the mass ratio: 200-300 parts of cow dung, 50-100 parts of mushroom dregs, and 40-80 parts of carboxymethyl cellulose , 60-80 parts of ammonium polyacrylate, 50-60 parts of ammonium sulfate, 40-80 parts of sodium nitrate, 60-80 parts of calcium magnesium phosphate fertilizer, 30-50 parts of carboxymethyl cellulose and the balance is water The present invention adopts the nutrients and reasonable proportions needed by the seeds during rice seedling raising, plus trace elements such as calcium, magnesium, nitrogen, etc., which can well promote the rapid growth of rice seedlings, and solve the problem of rice seedling raising to a large extent.

Description

Technical field: [0001] The invention relates to the technical field of agricultural production, in particular to a rice seedling raising substrate and a preparation method thereof. Background technique: [0002] Rice is one of the most important food crops in the world, and nearly half of the world's population uses rice as a staple food. my country is a big rice planting country, and the planting area is basically maintained at about 420-450 million mu. In recent years, with the acceleration of agricultural mechanization, machine-transplanted rice seedlings have been vigorously promoted across the country, and the proportion of machine-transplanted rice seedlings has increased year by year. Among them, machine-transplanted rice seedlings in Jiangsu Province have reached more than 50%, and even reached more than 85% in southern Jiangsu. However, machine transplanting technology has specific requirements on the quality of seedlings. How to cultivate blocky seedlings with s...

AI Technical Summary

Problems solved by technology

[0003] At present, studies on the effects of seedling raising methods, sowing density, sowing period and light environment on the quality of machine-transplanted seedlings have been reported.

However, there are few researches and patents about the preparation of light-weight seedling-raising substrates, and the patents for preparing seedling-raising substrates with rice husk organic substrates as the main raw material have not been published.

In the current production, most of the nutrient soils are prepared by farmers themselves. It is difficult for farmers to prepare nutrient soils to ensure a reasonable nutrient level, and because the seedling trays are too heavy, the mechanical work load is increased, which is not conducive to the promotion of large-scale and standardized machine-transplanted rice seedlings.
