Problems solved by technology

[0002] With the rapid development of my country's rural economy in the late 1990s, the area of ​​greening and planting of economic forest seedlings in many northern provinces continued to expand. Due to the strong wind and severe cold weather in the north in winter and spring, the newly planted saplings were frozen within a few days. And dry, the survival rate is very low

Embodiment Construction

[0018] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0019] Technical performance and formula produced by the present invention:

[0020] LLDPE 60%;

[0021] EVA 25%;

[0022] Metallocene 2018EB 15%.

[0023] The formula of the invention can increase the lateral tension of the bag; change the performance of the film to make the bag soft.

[0024] character

[0025] According to the height of the fixed pole of the newly planted saplings, the length and width specifications of the seedling protection bag are determined: 60cm*5cm, 80cm*5.5cm, 100cm*5.5cm, 1.2cm*5.5cm, 150cm*6cm. The antifreeze protection bag passes through the extruder Production or different width barrel ring film, cut to length according to the height of the fixed pole of the sapling, and seal at one end

[0026] Technical requirements: 1. Increase the transverse tensile force of the film (calculate the inflation ratio...

Abstract

The invention discloses an antifreeze moisturizing bag for tree seedlings and a making method of the antifreeze moisturizing bag and belongs to the technical field of agriculture. The formula comprises the following components: 60% of LLDPE (Linear Low Density Polyethylene), 25% of EVA and 15% of metallocene 2018EB. The invention further provides a making method of the antifreeze moisturizing bagfor tree seedlings. The novel antifreeze moisturizing bag for tree seedlings developed in the invention is not damaged in an environment at the temperature of about 20 DEG C below zero and at 5-7-grade wind within 20 days or longer, and achieves the effects of moisturizing, preventing air drying and preventing from dewatering. Therefore, the survival rate of the tree seedlings reaches 90% or higher.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to an antifreeze and moisture-retaining bag for saplings and a manufacturing method thereof. Background technique [0002] With the rapid development of my country's rural economy in the late 1990s, the area of ​​greening and planting of economic forest seedlings in many northern provinces continued to expand. Due to the strong wind and severe cold weather in the north in winter and spring, the newly planted saplings were frozen within a few days. And dry, the survival rate is very low. Contents of the invention [0003] The object of the present invention is to provide a kind of sapling antifreeze moisturizing bagging and manufacturing method thereof, and this product is in the environment of subzero 20 degrees, 5-7 grade wind environment, and bagging is not damaged more than 20 days, achieves moisturizing, anti-drying, Without dehydration, the survival of young saplings reache...
