Problems solved by technology

The rock wool seedling raising technology has not been further developed due to the constraints of harm to the human body and environmental pollution. Rice husk seedling raising has not been greatly improved due to the complexity of fermenting rice husk technology and the frequent occurrence of seedling diseases caused by bacterial contamination. The scope of promotion, vitrified microbeads has many unfavorable factors because of single perlite seedlings, because the permeability and conductivity of perlite is too strong, it is very sensitive to temperature response, hotter when it is hot, and cooler when it is cold, resulting in poor quality of seedlings , no seedlings, no roots, some places cannot transplant seedlings, dead seedlings often occur, and are not accepted by the common people

Embodiment Construction

[0015] Below in conjunction with embodiment the present invention is described in further detail:

[0016] Rice soilless seedling raising method of the present invention, it comprises the following specific steps:

[0017] 1) Proportioning matrix: Take 2 catties of perlite powder, 3 catties of peat, 4 kg of fermented plant straw powder, 4 catties of fermented livestock and poultry manure, and 20 g of slow-release fertilizer and mix evenly;

[0018] 2) In the prepared substrate, the moisturizing agent and adhesive should be included in the ratio of 15 grams of moisturizing agent and 20 grams of adhesive per 100 catties of substrate. After mixing evenly, put it into the seedling tray and scrape it flat, with a thickness of 0.6cm, and then watered, the watering rate is 1.0 kg / square meter;

[0019] 3) Sowing, sowing according to the seeding rate of 0.7 kg / square meter, after evenly sowing, lightly press the seeds with a flat plate to make the three sides of the seeds sink into th...

Abstract

The invention discloses a green and efficient rice soilless seedling raising method. The method includes the following steps: preparing a matrix according to a proportioning ratio; adding a humectantand an adhesive to the prepared matrix; and seeding at a seeding rate of 0.7 kg / m2; sprinkling burnt coal ash on paper with air ventilation holes, adjusting the pH value of the burned coal ash, then watering, then covering with a layer of moisture retention mulch film employing non-woven breathable film, pouring liquid fertilizer once on the 8th-12th day after uniform emergence of seedlings, and performing routine seedling raising management. The matrix employs turf, plant straw after fermentation, livestock and poultry manure after the fermentation, and the like, is rich in organic matter andhumic acid, is rich in trace elements, has all nutrients needed for a rice seedling period, and is light in volume weight, after rice seedlings are transplanted, the seedlings have no seedling recovering stage, the seedlings spring up fast in an early stage, the matrix has no diseased eggs and grass seeds, a seed bed does not use a seedling strengthening agent and herbicides, the method is greenand environmentally friendly, a strong seedling stage can be reached in 20-25 days, and a standard of transplanting rice seedlings by a machine can be achieved in 20 days.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a green and efficient method for cultivating rice seedlings without soil. Background technique [0002] Soilless rice seedling cultivation has a history of more than ten years. In northern China, rock wool, rice husk, vitrified microbeads, and perlite seedling cultivation techniques are more representative. The rock wool seedling raising technology has not been further developed due to the constraints of harm to the human body and pollution to the environment, and the rice husk seedling raising has not been greatly improved due to the complicated technology of fermenting rice husk and the frequent occurrence of seedling diseases caused by the contamination of bacteria. The scope of promotion, vitrified microbeads has many unfavorable factors because of single perlite seedlings, because the permeability and conductivity of perlite is too strong, it is very sensitive t...
