Black functional mulch dedicated for fruit tree

Abstract

The invention discloses a black functional mulch dedicated for a fruit tree, which is prepared from the following raw materials in percentage by weight: 35-45% of LLDPE(Linear low density polyethylene), 6-15% of LDPE(Low-density polyethylene), 5-12% of HDPE (High-density polyethylene), 15-25% of mPE (polyethylene), 8-15% of black master batch and 5-12% of functional master batch of mulch dedicated for a fruit tree, wherein the functional master batch of mulch dedicated for a fruit tree comprises the following raw materials in percentage by weight: 30-45% of LLDPE powder, 5-12% of LDPE, 5-12% of HDPE powder, 5-15% of mPE, 4-12% of hindered amine light stabilizer, 1.5-3.5% of antioxidant, 1.5-3.5% of ultraviolet absorber, 1.5-4.0% of dispersant stearic acid, 1.5-4.0% of dispersant polyethylene wax, 2-8% of herbicide acetochlor and 5-9% of insulating agent. According to the black functional mulch dedicated for a fruit tree, the problem that the common black mulch has short service life (about 80 days) and is easy to age is solved. The service life of the black functional mulch is above 12 months which is more than four times of the service life of the common black mulch. In addition,the functional effects on collecting rain, conserving moisture, lowering and keeping temperature and preventing weeds in the whole root system development, growth and fructescence period of the fruittree can be ensured. In addition, the black functional mulch is a pollution-free production which is easy to recover and is friendly to the environment, and the ecological environment is powerfully protected. The black functional mulch is widely suitable for fruit mulching cultivation in areas with the rainfall capacity of 300-500mm, big temperature difference and low temperature.

Description

technical field [0001] The invention relates to an agricultural ground covering film, in particular to a special black functional film suitable for fruit tree planting. Background technique [0002] Covering the soil under the canopy of fruit trees such as apples with black plastic film can increase yield and benefit, increase the rate of large fruit, prevent orchard weeds, and pests. A big innovation. This technology solves many problems in orchard soil management in one package, and has the effect of saving costs, improving quality, and increasing efficiency. However, the commonly used black mulch film has a service life of only about 80 days, and it is difficult to completely recycle it after aging, gradually forming a large area of ​​pollution. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a special black weed-killing mulch for fruit trees, whose service life can reach more than 12 months, thereby r...
