未成熟的“畜禽粪便”不是有机肥料!

更新时间:2016-03-04 出版者:通达

在畜禽粪便的堆肥过程中, 通过微生物的作用, the organic matter that is difficult to be used by crops is turned into nutrients that are easily absorbed by crops, 所以它可以被称为有机肥料. The high temperature of about 70°C generated in the process of composting can kill most germs and eggs, 基本上是无害的.

1. The possible harm caused by the application of immature organic fertilizers to fruits and vegetables. We can often see in rural areas that many vegetable farmers and fruit farmers directly apply immature organic fertilizers to the ground. 这会造成什么样的伤害?

(1)焚烧根系和幼苗. When the unfermented livestock and poultry manure is applied to the fruit and vegetable garden, 由于发酵不完全, it cannot be directly absorbed and utilized by the root system of the plant, and the phenomenon of "secondary fermentation" will occur. 发酵, when the fermentation part is close to the root or the crop plant is small, the heat generated by the fermentation will affect the growth of the crop, 造成“烧根烧苗”, 在严重的情况下, 这会导致植物的死亡.

(2)滋生害虫. The feces contain bacteria and pests such as coliform bacteria and nematodes. Direct use will 引领 to the spread of diseases and insect pests, 使农作物生病, and will also affect the health of people who eat agricultural products. When unripe organic matter is fermented in the soil, it is easy to breed bacteria. and insect pests, 引领ing to the occurrence of plant diseases and insect pests. 例如, the citrus fruit fly has a certain relationship with the application of manure, 也为越冬的害虫提供了一个地方, 如蛴螬和梨花网虫.

(3)产生有毒气体和缺氧. 在分解未成熟肥料的过程中. harmful gases such as methane and ammonia will be produced, which will cause acid damage to the soil and damage to the root system of plants. 与此同时, 在分解过程中, 土壤中的氧气会被消耗掉, 土壤就会处于缺氧状态. In this anoxic state, the growth of plants will be inhibited to a certain extent.

2. The harm caused by the application of immature chicken manure to fruits and vegetables. Chicken manure is the most complete and best manure among livestock manures. 然而, if it is applied to gardens such as fruits and vegetables when it is not fully decomposed, 它也会造成伤害, 而且它可能比其他肥料造成更大的危害.

(1)有机酸、氨气中毒. The direct application of chicken manure to the ground will produce organic acid, 哪些因素会影响种子的发芽, 在严重的情况下, 会导致种子和芽腐烂吗, 也会造成幼苗生长不良, 矮的植物, and excessive application of immature rot at the adult stage. Chicken manure can make the leaves of the plant turn yellow from top to bottom, 好像缺少某种元素.

(2)蝇类危害. The adult flies of the seed fly have the habit of tending to immature manure. 因此, 施用越不成熟的鸡粪, 种子对蝇幼虫的危害越严重. The larvae damage the germinated seeds and young stems, so that the seeds cannot germinate and unearth; they can also burrow into the roots or stems, causing malnutrition on the ground; the wounds caused by the threat are easy to cause the invasion of pathogenic microorganisms and cause invasiveness The occurrence of diseases will cause greater losses.

(3)盐渍土. 如果年复一年地使用鸡粪, a large amount of sodium chloride salt will remain in the soil. The average salt content per 6 cubic meters of chicken manure is about 40 kg, and the salt content of 10 kg per mu has seriously restricted soil permeability and activity, 什么能使磷凝固. , 钾肥, calcium magnesium zinc iron boron manganese and other trace elements, 植物生长异常, 稀疏的花蕾, 缺果等减产现象, significantly restricting the improvement of crop yield and quality.

(4)繁殖病毒病. 因为鸡粪是一种酸性很强的物质, it will cause 化学 trauma and serious damage to the plant stem base and root tissue. A large number of virus bacteria carried by chicken manure will break out when the humidity and temperature are suitable, 导致疾病和害虫的传播. , 繁殖的病毒病, 根腐病, 枯萎病和其他疾病, 导致植物枯萎, 黄枯萎, 死苗, 甚至死亡. Some plants are infected with viral diseases, blight, stem rot, 根腐病, bacterial wilt, etc., which are the most obvious sequelae of using chicken manure.

(五)重金属超标. The raw chicken manure that has not been decomposed and fermented contains a lot of heavy metals such as copper, 汞, 铬, 镉, 引领, 砷, 更多的激素残基, which will cause the heavy metals in agricultural products to exceed the standard, and these heavy metals are difficult to degrade and destroy The replacement has laid hidden dangers for the safety of food and the sustainable development of the agricultural industry.


Fermented chicken manure and livestock manure can not only be used for fruits and vegetables, but also a rare good fertilizer with very rich nutrients and long-lasting fertilizer effect. 很有帮助.
