Problems solved by technology

[0004] The technical problem to be solved by the present invention: the straw in the rice seedling raising substrate prepared mainly with crushed straw as the main raw material and with the addition of water-retaining agents decomposes too quickly, making its physical properties deteriorate, causing poor ventilation, and water-retaining agents, etc. Substances are difficult to decompose and cause soil pollution. A method is provided to mix river sludge, chicken manure and self-made expanded vermiculite powder, and add crushed conifer bark for mixing to dilute the heavy metals in river sludge and obtain After composting the mixed material, inoculating it with earthworms until the compost mixed material turns into vermicompost, mixing it with self-made acidified fermented wheat starch to prepare the rice seedling raising substrate

example 1

[0018] First weigh 2kg of vermiculite, put it into a universal pulverizer, pulverize and sieve, collect 40-mesh particles, then transfer the particles to a microwave heater, heat for 60min with 800W power, discharge, let stand, and naturally cool to room temperature to obtain puffed vermiculite powder; then weigh 600g of coniferous pine bark, soak it with 2L biogas tank supernatant for 5 days, take out the soaked coniferous pine bark, transfer it to a tissue grinder, grind it into sawdust, add In a mixer filled with 2L of clear water, add 4kg of river sludge, 300g of chicken manure and 800g of the above-mentioned expanded vermiculite powder in sequence, stir and mix for 2 hours at a speed of 800r / min, and discharge to obtain a mixed material; The stockpile is placed in a dark and ventilated place. Under the condition of temperature of 45 °C and relative air humidity of 75%, compost for 3 days, and then inoculate the mixed material after composting with 15% of the inoculum amoun...

Abstract

The invention relates to a preparation method of rice seedling matrixes, belonging to the agricultural field.The method comprises following steps: combining river sludge, chicken manure and self-prepared puffed vermiculite powder, mixing with crushed needle pine barks, diluting heavy metal in river sludge and obtaining combined material, carrying out compost treatment, inoculating earthworms till compost material turns into earthworm manure and mixing with self-prepared acidified and fermented starch wheat such that rice seedling matrixes can be prepared. The preparation method of rice seedling matrixes has following beneficial effects: ventilation and water retention are good so that seedlings can sprout out rapidly; allowable weight of matrixes are low and high nutrients are obtained so that seeding survival rate is increased; decomposable substance is included so that soil pollution is avoided and the environment is protected.

Description

technical field [0001] The invention relates to a preparation method of a rice seedling raising substrate, which belongs to the field of agriculture. Background technique [0002] Machine transplanting is a new type of intensive rice production technology and an important mode of rice production modernization. Standardized seedling raising using standard seedling trays, also known as rice seedling raising substrates, is a key technology in the rice production process. At present, most areas that use seedling trays to raise seedlings still use soil-based nutrient soil as the medium. Therefore, it will cause damage to a large amount of cultivated land surface soil due to soil extraction for seedling raising, causing water and soil loss, and damaging the environment; The process is labor-intensive; and the quality of the nutrient soil is unstable and cannot be standardized, which often leads to seedling failure; the above-mentioned shortcomings of the soil-based nutrient soil a...
