一、概况土面增温剂是一种农田化学复盖物.作为一种土壤水分蒸发抑制剂,在农林业生产上应用,具有增温保墒、固沙压碱、抵御风吹水蚀多种作用,从而提高产量.在农田上施加复盖物,这在我国已有悠久的历史.远在二千多年前的农书“汜胜之书”里就有记载,其它各种农书也都有所论述.而西方,只是到了十七世纪,枯枝落叶一类的物质复盖于农田这样的词汇才见诸于文献.到二十世纪三十年代,美、苏、日、澳等国利用石油、油脂等化工付产品制剂,代替原来的秸杆、细砂、卵石之类的物质复盖于农田,具有施用量小,使用方便,效果显著等优点,这种新制剂,一般称做农田化学复盖物,也叫水分蒸发抑制剂.我国因目前主要是用于早春提高地温,故被通俗地称为土面增温剂.
First, an overview Soil warming agent is a farmland chemical covering .As a soil moisture evaporation inhibitor, applied in the production of agriculture and forestry, with warming soil moisture, sand and alkali, resist the wind and water erosion, a variety of roles, Thus increasing the output.Applying cover in the farmland, which has a long history in our country.More than two thousand years ago, the agricultural book “Book of Wisdom wins” there are records, other kinds of agricultural books also have However, in the West, it was only in the 17th century that the words such as litter covered the fields were found in the literature. By the 1930s the United States, the Soviet Union, Japan, Australia and other countries used Oil, grease and other chemical products, instead of the original straw, sand, pebbles and other substances covered in farmland, with a small amount of application, easy to use, the effect is significant, etc. This new preparation, commonly known as farmland Chemical covering, also known as moisture evaporation inhibitor.Our country is mainly used for increasing ground temperature in early spring, it is popularly known as soil surface temperature agent.
