Description
Technical field
The present invention relates to ground technical field of membrane, and in particular to a kind of whole life cycle design PP Pipe Compound and preparation method thereof.
Background technique
Agricultural problem is always the grand strategy problem for being related to China's national economy.Mulch is as the important of agricultural production
One of material goods have greatly facilitated crop yield, improve agricultural benefit, driven mode of agriculture change and
Agricultural productive force is developed by leaps and bounds.According to statistics, the popularization and application of film-mulching technique make whole world crops fit kind of an area and exist
Northern Hemisphere and Southern Hemisphere is to the south respectively, north has elapsed 2-4 ° of geographic latitude, and 500-1000 meters of height above sea level has been elapsed to alpine region
Degree, crop generally increase production 10-50%.However, common agricultural mulching mostly uses nondegradable polythene material, agriculture is not only brought
Industry produces upper serious " white pollution ", and brings great threat to the sustainable use in arable land.China is covered for a long time at present
In the agricultural soil of lid mulch, mulch residual quantity reaches 3-15 kilograms in average field per acre.A large amount of remaining mulch fragments are made
It is destroyed at agricultural land soil structure, farmland quality decline, farming operations are obstructed, and the development of agricultural productive force is seriously hindered.Biology
The appearance of degradative plastic film brings a kind of new effective way in order to solve the above problem.
