Description

一种微胶囊有机化肥的制备方法A kind of preparation method of microcapsule organic fertilizer

技术领域 technical field

本发明涉及一种微胶囊有机化肥,特别是涉及一种微胶囊有机化肥的制备方法。The invention relates to a microcapsule organic fertilizer, in particular to a preparation method of the microcapsule organic fertilizer.

背景技术 Background technique

有机肥料是指含有有机物质,既能提供农作物多种无机养分和有机养分,又能培肥改良土壤的一类肥料。其中绝大部分为农家就地取材,自行积制的。施用有机肥料是数千年来中国传统农业发展的根本措施,尽管近一时期化肥用量不断增加,但在当今日益重视人类生存环境的情况下,有机肥料再度受到人们的关注。有机肥料依靠日变幅较小的土壤水热动态周期性变化,给微生物活动创造一个良好的环境,使它能够顺利通过腐殖化阶段,形成保水保肥力高的腐殖质,从而提高土壤的肥力及作物产量和品质。Organic fertilizer refers to a type of fertilizer that contains organic substances and can not only provide a variety of inorganic and organic nutrients for crops, but also fertilize and improve the soil. Most of them are collected by farmers on the spot and made by themselves. The application of organic fertilizers has been the fundamental measure for the development of traditional Chinese agriculture for thousands of years. Although the amount of chemical fertilizers has been increasing in recent times, organic fertilizers have once again attracted people's attention under the circumstances of today's increasing emphasis on human living environment. Organic fertilizers rely on the periodic changes in soil water and heat dynamics with small daily fluctuations to create a good environment for microbial activities, enabling them to pass through the humification stage smoothly and form humus with high water and fertility retention, thereby improving soil fertility and Crop yield and quality.

有机肥料是农业中养分的再循环和再利用部分,因此,随着化肥施用量的增加和作物收获物的增多,有机肥料的数量也有所增加。虽然近年来由于化肥投入的大量增加,有机肥料投入的养分所占的比例显著降低,但仍占总养分总投入量的36.7%,有机肥料除含有氮、磷、钾和有机碳养分外,还可提供相当数量的中量、微量元素和氨基酸、核酸、糖、维生素等有机营养成分。有机肥料由于来源广泛,所以种类很多,一般可分以下几类:一是粪尿肥,包括人粪尿、家畜粪尿、禽粪等。二是堆沤肥类,包括堆肥、沤肥、秸秆还田及沼气酵肥等,各种原料制成的堆肥都含有作物需要的氮、磷、钾和微量元素,有利于培肥土壤囝;秸秆占作物生物量的50%左右,是一类数量极其丰富、能直接利用的有机肥资源。三是饼肥类,包括大豆饼、花生饼、菜饼和茶籽饼等。四是泥炭类,又称草炭。含有较多的腐植酸,可用于制造腐植酸铵、硝基腐植酸铵、腐植酸钠等腐植酸肥料。五是泥土类,包括塘泥、湖泥、河泥、墙土、坑土等。六是城镇废弃物类,包括生活污水、工污水、屠宰场废弃物、垃圾和各种有机废弃物等。七是杂肥类,包括皮屑、蹄角、海肥、蚕粪。Organic fertilizers are part of the recycling and reuse of nutrients in agriculture, so the amount of organic fertilizers has increased as fertilizer applications have increased and crop harvests have increased. Although in recent years, due to the large increase in chemical fertilizer input, the proportion of nutrients input into organic fertilizers has decreased significantly, but it still accounts for 36.7% of the total nutrient input. In addition to nitrogen, phosphorus, potassium and organic carbon nutrients, organic fertilizers also contain It can provide a considerable amount of medium and trace elements and organic nutrients such as amino acids, nucleic acids, sugars, and vitamins. Due to the wide range of sources, there are many types of organic fertilizers, which can generally be divided into the following categories: First, manure fertilizers, including human excrement, livestock excrement, poultry manure, etc. The second is composting manure, including composting, retting manure, straw returning to the field and biogas fermentation fertilizer, etc. Compost made of various raw materials contains nitrogen, phosphorus, potassium and trace elements needed by crops, which is conducive to fertilizing the soil; About 50% of crop biomass is a kind of organic fertilizer resource that is extremely abundant and can be directly used. The third is cake fertilizer, including soybean cake, peanut cake, vegetable cake and tea seed cake. The fourth is peat, also known as peat. Contains more humic acid, which can be used to make humic acid fertilizers such as ammonium humate, ammonium nitrohumate, and sodium humate. The fifth is soil, including pond mud, lake mud, river mud, wall soil, pit soil, etc. The sixth is urban waste, including domestic sewage, industrial sewage, slaughterhouse waste, garbage and various organic wastes. The seventh is miscellaneous fertilizers, including dander, hoof horns, sea manure, and silkworm dung.

微胶囊能保护物质免受环境影响,屏蔽味道、颜色、气味,改变物质重量、体积、状态或表面性能,隔离活性成分,降低挥发性和毒性,控制可持续释放等多种作用,自二十世纪三十年代至今,微胶囊已被广泛应用于医学、食品、农药、化妆品、金属切削、涂料、油墨、添加剂等多个领域。微胶囊的制备首先是将液体、固体或气体囊心物质(芯材)分细,然后以这些微滴(粒)为核心,使聚合物成膜材料(壁材)在其上沉积,涂层,形成一层薄膜,将囊心微滴(粒)包覆。这个过程称为微胶囊化。微胶囊化方法很多,但还没有一种规范的方法可以使用于所有微胶囊的生产,故有关微胶囊方面的文献虽然很多,但大多是描写某一个具体的微胶囊化过程或介绍微胶囊技术在某一领域的应用。Microcapsules can protect substances from environmental influences, shield taste, color, smell, change the weight, volume, state or surface properties of substances, isolate active ingredients, reduce volatility and toxicity, control sustainable release, etc. Since 20 Since the 1930s, microcapsules have been widely used in many fields such as medicine, food, pesticides, cosmetics, metal cutting, coatings, inks, and additives. The preparation of microcapsules is first to divide the liquid, solid or gas capsule core material (core material), and then use these droplets (particles) as the core to deposit polymer film-forming material (wall material) on it, coating , forming a layer of thin film, the capsule core droplet (granule) coating. This process is called microencapsulation. There are many methods of microencapsulation, but there is no standardized method that can be used in the production of all microcapsules. Therefore, although there are many literatures on microcapsules, most of them describe a specific microencapsulation process or introduce microencapsulation technology. application in a certain field.

微胶囊剂可谓是当前农药新剂型中技术含量最高的一种,虽然,它在农药制剂市场中占据的份额还很小,远排不上农药主要剂型的地位,但鉴于它拥有诸多极具魅力的优点和功能,已日益引起人们的广泛关注,特别是即将到来的人们对于安全、环境生态和可持续发展的意识不断增强,微胶囊剂的许多优点势必将成为农药制剂的重要发展方向。Microcapsules can be said to be one of the most technologically advanced new formulations of pesticides. Although its share in the pesticide formulations market is still very small, it is far from the status of the main formulations of pesticides. However, given its many attractive features The advantages and functions of microcapsules have increasingly attracted people's attention, especially the upcoming people's awareness of safety, environmental ecology and sustainable development. Many advantages of microcapsules are bound to become an important development direction of pesticide formulations.
