农业添加剂中凹凸棒的性能
Properties of attapulgite in agricultural additives

　　凹凸棒无论是利用在农业还是药业里都是非常值得研究的，那么在畜牧业以及植物生长里凹凸棒饲料添加剂起着哪些预防以及性能特点呢？下面，我们就来深究一番吧！

　　首先，凹凸棒农业施用时可单独使用，也可与其他肥料、农家肥掺和使用，需减去之前肥料的30-50%的量，可以做底肥、追肥用，不可滴灌。一般大棚蔬菜一亩地初次使用150-200公斤左右，隔年缓慢减少到100公斤，果园一颗一年生树可用1斤。

　　其次因为凹凸棒石细腻且有粘附作用，与盐类混合后不易分离，用其制成颗粒饵料，具有良好的漂浮性和粘结性，符合鱼类颗粒饵料的质量要求；比重轻，沉降速度慢，可延长鱼的觅食机会，提高饲料利用率。同时，凹凸棒石还能吸附鱼塘中的氨离子，防水质污染和腐臭。

　　当然，畜禽使用饲料添加剂后，能够增加猪只体重，有效预防疾病的发生，并且针对矿物质缺乏症，微量元素缺乏症治疗效果明显。

　　综上所述，大家对凹凸棒饲料添加剂在动植物研究上的有效应用也多了一项了解，也因此凹凸棒饲料添加剂值得在临床上大力推广。

　　Whether attapulgite is used in agriculture or medicine industry is very worthy of study. What prevention and performance characteristics of attapulgite feed additive play in animal husbandry and plant growth? Now, let's take a closer look!
　　First of all, attapulgite can be used alone or mixed with other fertilizers and farmyard manure. The amount of 30-50% of the previous fertilizer should be subtracted. It can be used as base fertilizer and topdressing, but not drip irrigation. Generally, the first use of greenhouse vegetables is about 150-200 kg per mu of land for the first time, and then slowly reduced to 100 kg every other year. An annual tree in orchard can use 1 jin.
　　Secondly, because attapulgite is fine and has adhesion, it is not easy to separate when mixed with salt. It has good floatability and cohesiveness, which meets the quality requirements of fish pellet bait. Due to its light specific gravity and slow settling speed, it can prolong fish's foraging opportunities and improve feed utilization rate. At the same time, attapulgite can also adsorb ammonia ions in the fish pond to prevent water pollution and putrefaction.
　　Of course, the use of feed additives can increase the weight of pigs, effectively prevent the occurrence of diseases, and for mineral deficiency, trace element deficiency disease treatment effect is obvious.
　　To sum up, we have more understanding of the effective application of attapulgite feed additive in animal and plant research. Therefore, attapulgite feed additive is worthy of clinical promotion.
