Problems solved by technology

If solid organic fertilizers are completely used as fertilizers, the total supply of nutrients is insufficient and the release rate of nutrients is slow, thus affecting the growth of vegetables. The production level is low and cannot be compared with inorganic nutrient hydroponics.

Embodiment 1

[0019] Production of organic liquid fertilizer from water hyacinth.

[0020] Method: The freshly salvaged water hyacinth is crushed by a pulverizer, squeezed by a juicer, separated from solid and liquid by a filter, and sterilized by an ozone generator to obtain an organic liquid fertilizer.

[0021] The produced organic liquid fertilizer was used in the soilless cultivation of eggplant organic composite substrate, drip irrigation with nutrient solution of solanaceous vegetables every morning, and drip irrigation with organic liquid fertilizer diluted 10 times in the afternoon, and the control only used nutrient solution drip irrigation of solanaceous vegetables. The output is as follows: the output of eggplant grown with organic liquid fertilizer is 2692 kg / mu, and the output of control eggplant is 2390 kg / mu, with an increase of 11.2%.

Embodiment 2

[0023] Production of organic liquid fertilizer from cucumber leaves.

[0024] Method: The freshly crushed old cucumber leaves are pulverized by a pulverizer, squeezed by a juicer, separated from solid and liquid by a filter, and sterilized by an ozone generator to obtain an organic liquid fertilizer.

[0025] The produced organic liquid fertilizer was used in the soilless cultivation of eggplant organic composite substrate, drip irrigation with nutrient solution of solanaceous vegetables every morning, and drip irrigation with organic liquid fertilizer diluted 10 times in the afternoon, and the control only used nutrient solution drip irrigation of solanaceous vegetables. The output is as follows: the output of eggplant grown with organic liquid fertilizer is 2712 kg / mu, and the output of control eggplant is 2390 kg / mu, with an increase of 13.5%.

Abstract

A process for preparing organic liquid fertilizer from water hyacinth and the stem and leaf of agricultural crops includes breaking raw materials, squeezing, solid-liquid separation, sterilizing the liquid by ozone, microbial fermenting, and mixing with the dregs generating by fermentation to prepare marsh gas. Its advantages are high fertility and no environmental pollution.

Description

1. Technical field: [0001] The invention relates to an organic fertilizer, and in particular discloses a process for producing organic liquid fertilizer by using water hyacinth and crop stems and leaves. The invention is mainly used for soilless cultivation of vegetables, fruits, flowers and seedlings, and belongs to the field of modern agriculture. 2. Background technology: [0002] The general trend of the world's agricultural development is to develop organic agriculture, and vegetable cultivation in our country should also follow this development trend. Especially since our country has joined the WTO, only the development of high-quality vegetables can be competitive in the international market, and organic vegetables are the hope of earning foreign exchange through export. [0003] The core of developing organic agriculture is to establish an organic agricultural production system. The establishment of this system requires a conversion process from inorganic to organic....
