Problems solved by technology

[0003] Using chemical fertilizers for a long time will pollute resources, cause many plant diseases, it is difficult to increase the yield, and the product quality is low; in soilless cultivation, it is easy to burn the roots, the plant growth is not vigorous, there are many diseases, the yield is low, and the nitric acid in the product Salt content and pesticide residues are difficult to control, and the product quality is poor
At present, inorganic fertilizers are used in soilless cultivation, which can only produce pollution-free products, which cannot meet the requirements of organic products.

Embodiment 1

[0033] A soilless cultivation method utilizing organic fertilizer, comprising the following steps:

[0034] 1. Matrix preparation and disinfection

[0035] Mix the sand and slag outside the shed according to the mass ratio of 2:1, and pour evenly a formaldehyde solution with a mass percentage concentration of 1.5% from the top. If seepage is found under the stacking matrix, immediately cover it with a plastic film and seal it for disinfection for two weeks. After that, close the tuyere of the greenhouse in August every year, and use the sun and high temperature to sterilize the greenhouse for a week.

[0036] 2. Fill the substrate into the cultivation ditch

[0037] After two weeks, remove the plastic film and dry it in the air for 1-2 days to volatilize the residual formaldehyde, and fill the sterilized matrix into the cultivation ditch.

[0038] 3. Preparation before planting

[0039] First, open the seal to air the shed for 1 day. During the airing period, check whether ...

Embodiment 2

[0059] A soilless cultivation method utilizing organic fertilizers is applied to tomato cultivation, comprising the following steps:

[0060] 1. Production of soybean meal fertilizer

[0061] Before the seedlings are planted, soak the soybean meal or soybean cake (broken into small pieces) with water and pile them on the outdoor cement ground, cover them with plastic film and seal them for fermentation. A week later, when the plastic film bulges and feels difficult to press with your hands, use a fine needle to pierce about 10 small holes in the upper part of the pile to let the gas slowly release every day, so as not to affect the fermentation due to too much internal pressure. Ferment for one month and remove the plastic film to dry the fertilizer for later use. In July, the light time is long, the temperature is high, and the fermentation time is short, which can quickly decompose organic matter.

[0062] 2. Production of root strengthening agent

[0063] Purchase microb...

Abstract

The invention discloses a soilless culture method utilizing an organic fertilizer. The method comprises the steps of base material preparation and disinfection, filling of the base materials in cultivate furrows, pre-planting preparation, planting, post-planting management and the like. According to the planting step, 5 g to 7 g of root strengthening agents for every plant and fine sand are evenly stirred to be applied to roots. The soilless culture method is applied to tomato planting and comprises the steps of bean pulp fertilizer preparation, root strengthening agent preparation, culture medium processing, seedling planting, post-planting management and two crop rotations every year. According to the method, operation is convenient, quantitative fertilization is achieved, no roots are injured, few diseases exist, no pesticide is needed, the product nitrate content is greatly lowered, the requirement for organic agricultural products can be met, the yield is high, the quality is good, the product has the unique flavor and taste, and meanwhile the technical problem that organic fertilizers and organic matter are difficult to decompose when used in gravel is solved.

Description

technical field [0001] The invention relates to a soilless cultivation method using organic fertilizer and its application, belonging to the field of soilless cultivation. Background technique [0002] Soilless cultivation is divided into hydroponics, aerosol cultivation and substrate cultivation. All soilless cultivation in my country uses soluble inorganic salts as plant nutrients. [0003] Using chemical fertilizers for a long time will pollute resources, cause many plant diseases, it is difficult to increase the yield, and the product quality is low; in soilless cultivation, it is easy to burn the roots, the plant growth is not vigorous, there are many diseases, the yield is low, and the nitric acid in the product Salt content and pesticide residues are difficult to control, resulting in poor product quality. At present, inorganic fertilizers are used in soilless cultivation, which can only produce pollution-free products, which cannot meet the requirements of organic ...
