Method for preparing rice straw fermented fertilizer special for asparagus lettuce

Abstract

The invention belongs to the technical field of rice straw biological treatment, and particularly relates to a method for preparing a rice straw fermented fertilizer special for asparagus lettuce. Themethod comprises the steps of (1) weighing raw materials; (2) frying black beans, mixing and smashing with fresh carrot tops, conducting steam treatment, taking out, and cooling to room temperature to obtain a bean top material; (3) mixing and crushing rice straw and pig manure, steaming, taking out, cooling to the room temperature, adding the bean top material and compound bacteria, mixing, stirring evenly, closing, fermenting, and obtaining a first fermenting material; (4) adding mangosteen polysaccharide, glycyrrhetinic acid, pineapple extract, puerarin extract and compound biological bacteria to the first fermenting material, mixing, stirring uniformly, sealing, fermenting, adding borax and magnesium chloride, sealing, fermenting, granulating, and obtaining the rice straw fermented fertilizer special for the asparagus lettuce; the method promotes the robust growth of the asparagus lettuce, effectively avoids the occurrence of asparagus lettuce hollowness, increases the selenium, carotene and zinc content of asparagus lettuce, effectively improves the utilization efficiency of the rice straw and promotes the economic benefits of asparagus lettuce planting.

Description

technical field [0001] The invention belongs to the technical field of rice straw biological treatment, in particular to a preparation method of special rice straw fermented fertilizer for lettuce. Background technique [0002] Lettuce, also known as lettuce, is a variety of lettuce of the genus Lactuca in the Compositae family that can form fleshy tender stems. It is a biennial herb plant with edible stems above the ground. It mainly eats meaty tender stems, which can be eaten raw, cold, fried, dried or pickled. It is one of the vegetables that people often eat in daily life. It can improve the symptoms of low acidity and weak digestive function in the digestive tract, and is beneficial to promote milk secretion and Volleyball is a therapeutic vegetable for patients with edema, high blood pressure and heart disease. It can regulate the nervous system of the human body, promote intestinal peristalsis, improve constipation, help the mother fully absorb various nutrients, and ...

Problems solved by technology

[0003] The amount of straw resources that can be collected in China is nearly 700 million tons per year, but more than 30% of the straw is placed in the field, of which rice straw accounts for nearly 1 / 3 of the total; due to the lack of feasible collection, treatment and utilization technologies, a large amount of straw Incineration has led to serious air pollution and waste of resources. Effectively improving the utilization rate of rice straw is one of the effective ways to solve China's increasingly severe energy and environmental problems, and has great development potential and research significance; however, rice straw contains a large amount of Refractory cellulose, hemicellulose and lignin are mixed and cross-linked with each other, making it difficult to degrade cellulose and other digestible nutrients that can be used by microorganisms. The special and complex fiber structure seriously restricts the straw utilization efficiency; therefore, processing rice straw for lettuce planting can effectively improve resource utilization efficiency
