Organic leach liquor tablet for plant production and preparation method thereof

Abstract

The invention discloses an organic leach liquor tablet for plant production and a preparation method thereof, and belongs to the crossing field of facility agriculture engineering technology and pharmaceutics, the tablet comprises 15%-45% by mass of a main drug and auxiliary materials, and the main drug is an organic leach liquor extracted from non-edible parts of plants, livestock and poultry excreta or agricultural wastes. The auxiliary materials comprise the following components in percentage by mass: 30%-45% of an acid source, 15%-27% of an alkali source, 1%-5% of polyethylene glycol and 2%-8% of polyvinylpyrrolidone. The preparation method comprises the following steps: taking an organic leaching solution extracted from non-edible parts of plants, excrements of livestock or agricultural wastes as a main drug, the main drug and the auxiliary materials are uniformly mixed according to the proportion, sieved and tableted to obtain tablets, or the main drug is respectively mixed withan acid source and an alkali source to prepare a soft material, the soft material is dried to obtain acid granules and alkali granules, and the acid granules and the alkali granules are mixed and tableted to obtain the tablets.

Description

technical field [0001] The invention belongs to the intersection field of protected agricultural engineering technology and pharmacy, and specifically relates to an organic extract tablet for plant production and a preparation method thereof. Background technique [0002] As a relatively new cultivation method, soilless cultivation has been developed for decades. Its principle is based on the theory of mineral nutrition of plants. Up to now, nutrient solution formulas for soilless cultivation have emerged in an endless stream, but the chemicals used The types have not changed, that is, calcium salts, magnesium salts, iron salts, nitrates, potassium salts, molybdates and other water-soluble salts that contain essential nutrients for plants and do not react with each other in aqueous solution. The different formulas are just the dosage. adjustment. Due to people's deep-rooted impression of traditional agricultural cultivation, people have doubts about the safety of vegetables...

Problems solved by technology

In addition, in the conventional nutrient solution configuration process, it is necessary to decompose the configuration process into three dissolution stages A, B, and C (sometimes also divided into two stages A and B) based on the properties of chemicals. The process is cumbersome and requires plant physiology and related chemistry. Knowledge background, which also increases the planting threshold for the public to carry out soilless cultivation

[0003] In recent years, some scientific research institutes have used the extracts of some biological organic residues or agricultural wastes after special fermentation treatment for plant cultivation, such as plant stems, leaves, or livestock and poultry manure, urine, etc. for fermentation and extraction. It is mentioned that some experiments have shown that organic extracts are rich in amino acids, and these small molecular amino acids can be absorbed and utilized by plants, which can increase the synthesis of chlorophyll in plants, regulate the opening of stomata, etc., and the quality of plant fruits cultivated with them is excellent. And it can significantly reduce the nitrate content. However, due to the liquid form of the organic extract, its storage and circulation are inconvenient, which affects the possibility of its commercialization. Organic extracts are often prepared and used immediately, and there is still a lot of room for improvement
